In order to reduce accidents and enhance the safe operation of mowers, Alamo Group Ag Division, in
cooperation with other industry manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower Safety Practices video and guide book.
The video will familiarize and instruct mower-tractor operators in safe practices when using industrial
and agricultural mowing equipment. It is important that Every Mower Operator be educated in the operation of their mowing equipment and be able to recognize the potential hazards that can occur while operating a mower. This video, along with the mower operator’s manual and the warning messages on the
mower, will significantly assist in this important education.
Your Authorized Alamo Ag Dealer may have shown this video and presented you a DVD Video when you
purchased your mower. If you or any mower operator have not seen this video, Watch the Video, Read
this Operator’s Manual, and Complete the Video Guidebook before operating your new mower. If you
do not understand any of the instructions included in the video or operator’s manual or if you have any
questions concerning safety of operation, contact your supervisor, dealer or Alamo Group Ag.
If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax

General Safety Instructions and Practices

SAFETY

A safe and careful operator is the best operator. Safety is of primary importance to the manufacturer and
should be to the owner/operator. Most accidents can be avoided by being aware of your equipment, your
surroundings, and observing certain precautions. The first section of this manual includes a list of Safety
Messages that, if followed, will help protect the operator and bystanders from injury or death.
Read and
understand these Safety Messages before assembling, operating or servicing this Implement.
This
equipment should only be operated by those persons who have read the Manual, who are responsible and
trained, and who know how to do so safely and responsibly.
The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this manual and on
decals which are attached to the equipment. The Safety Alert Symbol means: “ATTENTION! BECOME
ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal Word are intended to warn the owner/
operator of impending hazards and the degree of possible injury faced when operating this equipment.
Practice all usual and customary safe working precautions and above all---remember safety is
up to YOU. Only YOU can prevent serious injury or death from unsafe practices.

The lowest level of Safety Message; warns of possible injury. Decals located on the Equipment
with this Signal Word are Black and Yellow

Serious injury or possible death! Decals are Black and Orange.

Imminent death/critical injury. Decals are Red and White.

(SG-1)

READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or
death may occur unless care is taken to follow the warnings and instructions stated in the
Safety Messages. Always use good common sense to avoid hazards. (SG-2)

Safety Section 1-2

SAFETY
Engine Exhaust, some of its constituents, and certain vehicle components contain or emit
chemicals known to the state of California to cause cancer and birth defects or other reproductive
harm. (SG-30)
Battery posts, terminals and related accessories contain lead and lead compounds, chemicals
known to the state of California to cause cancer, birth defects or other reproductive harm. (SG-31)

The rotating parts of this machine continue to rotate even after the PTO has been turned off. The
operator should remain in his seat for 60 seconds after the brake has been set, the PTO
disengaged, the tractor turned off, and all evidence of rotation has ceased. (S3PT-10)
“Wait a minute...Save a life!”
Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch. Release of
the control lever or mechanical failure will result in the Implement falling and possible injury or
death. Always securely block up the Implement before crawling underneath to perform repairs
and service. (S3PT-19)
Never operate the Tractor or Implement until you have read and completely
understand this Manual, the Tractor Operator’s Manual, and each of the Safety
Messages found in the Manual or on the Tractor and Implement. Learn how to
stop the tractor engine suddenly in an emergency. Never allow inexperienced
or untrained personnel too operate the Tractor and Implement without
supervision. Make sure the operator has fully read and understood the manuals
prior to operation. (SG-4)
The operator and all support personnel should wear hard hats, safety shoes,
safety glasses, and proper hearing protection at all times for protection from
injury including injury from items thrown by the equipment. (SG-16)

Safety Section 1-3

SAFETY

Operator Safety Instuctions and Practices

SAFETY

PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT
HEARING LOSS! Tractors with or without an Implement attached can often be
noisy enough to cause permanent hearing loss. We recommend that you
always wear hearing protection if the noise in the Operator’s position exceeds
80db. Noise over 85db over an extended period of time will cause severe
hearing loss. Noise over 90db adjacent to the Operator over an extended
period of time will cause permanent or total hearing loss. NOTE: Hearing loss
from loud noise [from tractors, chain saws, radios, and other such sources close
to the ear] is cumulative over a lifetime without hope of natural recovery. (SG-I7)

Always read carefully and comply fully with the manufacturers instructions when
handling oil, solvents, cleansers, and any other chemical agent. (SG-22)

KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement and
possible serious injury or death. (SG-24)

Never allow children to play on or around Tractor or Implement. Children can slip or fall off the
Equipment and be injured or killed. Children can cause the Implement to shift or fall crushing
themselves or others. (SG-25)
NEVER use drugs or alcohol immediately before or while operating the Tractor
and Implement. Drugs and alcohol will affect an operator’s alertness and
coordination and therefore affect the operator’s ability to operate the equipment
safely. Before operating the Tractor or Implement, an operator on prescription
or over-the-counter medication must consult a medical professional regarding
any side effects of the medication that would hinder their ability to operate the
Equipment safely. NEVER knowingly allow anyone to operate this equipment
when their alertness or coordination is impaired. Serious injury or death to the
operator or others could result if the operator is under the influence of drugs or
alcohol. (SG-27)

Prolonged operation may cause operator boredom and fatigue affecting safe operation. Take
scheduled work breaks to help prevent these potentially impaired operating conditions. Never
operate the Implement and Tractor in a fatigued or bored mental state which impairs proper and
safe operation. (SG-32)

Safety Section 1-4

SAFETY
Use extreme caution when getting onto the Implement to perform repairs, maintenance and when
removing accumulated material. Only stand on solid flat surfaces to ensure good footing. Use a
ladder or raised stand to access high spots which cannot be reached from gound level. Slipping
and falling can cause serious injury or death. (SG-33)
Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and hose
connections. Relieve hydraulic pressure before performing maintenance or repairs. Use gloves
and eye protection when servicing hot components. Contact with a hot surface or fluid can cause
serious injury from burns or scalding. (SG-34)

Avoid contact with hot surfaces of the engine or muffler. Use gloves and eye protection when
servicing hot components. Contact with a hot surface or fluid can cause serious injury from burns
or scalding. (SG-38)

Do not put hands or feet under mower decks. Blade Contact can result serious
injury or even death. Stay away until all motion has stopped and the decks are
securely blocked up. (SGM-9)

Always keep a careful lookout and use extreme care when working around utility and municipal
obstructions. Never allow the Mower to contact any utility, municipal, or other type structure.
Clearly mark all mowing obstructions and consult local utility providers for a safe code of
operation. (SPU-5)

Do not operate the implement while wearing loose fitting clothing. Entanglement of the clothing
with the rotating elements can result in serious injury or even death.
Stay clear of all rotating
elements at all times. (SSP-3)

Equipment Operation Safety Instructions and Practices
Never leave the Tractor and Implement unattended while the Implement is in the lifted position.
Accidental operation of lifting lever or a hydraulic failure may cause sudden drop of unit with injury
or death by crushing. To properly park the implement when disconnecting it from the tractor,
lower the stand and put the retaining pin securely in place, or put a secure support under the AFrame. Lower the implement carefully to the ground. Do not put hands or feet under lifted
components. (S3PT-1)

Safety Section 1-5

SAFETY

DO NOT operate this Implement on a Tractor that is not properly maintained. Should a
mechanical or Tractor control failure occur while operating, immediately shut down the Tractor and
perform repairs before resuming operation. Serious injury and possible death could occur from
not maintaining this Implement and Tractor in good operating condition. (SG-36)

SAFETY
Use extreme care when lowering or unfolding the implement’s wings. Make sure no bystanders
are close by or underneath the wings. Allow ample clearance around the implement when folding
or unfolding the wings. Use extreme caution around buildings or overhead power lines. (S3PT-5)

SAFETY

This Implement is wider than the Tractor.
Be careful when operating or transporting this
equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete
abutments or other solid objects. Such an impact could cause the Implement and Tractor to pivot
violently resulting in loss of steering control, serious injury, or even death. Never allow the
Implement to contact obstacles. (S3PT-12)
Be sure you have adequate knowledge of the property you will be working on. Take time to make
yourself aware of any area underground lines or cables. Contact with buried lines or cable could
result in serious injury or death. (SBH-6)

Do not operate Mower if excessive vibration exists.
Shut down PTO and the Tractor engine.
Inspect the Mower to determine the source of the vibration.
If Mower blades are missing or
damaged replace them immediately.
Do not operate the mower until the blades have been
replaced and the Mower operates smoothly. Operating the Mower with excessive vibration can
result in component failure and broken objects to be thrown outward at very high velocities. To
reduce the possibility of property damage, serious injury, or even death, never allow the Mower to
be operated with blades missing. (SFL-4)
Operate this Equipment only with a Tractor equipped with an approved rollover-protective system (ROPS). Always wear seat belts. Serious injury or even
death could result from falling off the tractor--particularly during a turnover when
the operator could be pinned under the ROPS. (SG-7)

BEFORE leaving the tractor seat, always engage the brake and/or set the
tractor transmission in parking gear, disengage the PTO, stop the engine,
remove the key, and wait for all moving parts to stop. Place the tractor shift
lever into a low range or parking gear to prevent the tractor from rolling. Never
dismount a Tractor that is moving or while the engine is running. Operate the
Tractor controls from the tractor seat only. (SG-9)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)

SE4 05/05

Safety Section 1-6

SAFETY
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and responsible
can operate the implement with adult supervision, if they have read and
understand the Operator’s Manuals, been trained in safe operation of the
tractor and Implement, and are physically large enough to reach and operate
the controls easily. (SG-11)
Do not mount the Tractor while the tractor is moving. Mount the Tractor only
when the Tractor and all moving parts are completely stopped. (SG-12)

Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and fuel are
expensive and their presence could present a hazard. Do not check for leaks
with your hand! High-pressure oil streams from breaks in the line could
penetrate the skin and cause tissue damage including gangrene. To check for a
hose leak, SHUT the tractor ENGINE OFF and remove all hydraulic pressure.
Wear oil impenetrable gloves, safety glasses and use Cardboard to check for
evidence of oil leaks. If you suspect a leak, REMOVE the HOSE and have it
tested at a Dealer. If oil does penetrate the skin, have the injury treated
immediately by a physician knowledgeable and skilled in this procedure. (SG-15)

Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust
fumes can be hazardous to your health. (SG-23)

Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death. (SG-26)

Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat with
the seat belt securely fastened around you. Inadvertent movement of the Tractor or Implement
may cause serious injury or death. (SG-29)
SE4 05/05

Safety Section 1-7

SAFETY

Start tractor only when properly seated in the Tractor seat. Starting a tractor in
gear can result in injury or death. Read the Tractor operators manual for proper
starting instructions. (SG-13)

SAFETY
In case of mechincal difficulty during operation, place the transmission in the park position, set
the parking brake, shut down all power, including the PTO and the engine and remove the key.
Wait until all rotating motion has stop before dismounting. (SG-39)

SAFETY

Do Not operate this equipment in areas where insects such as bees may attack you and/or cause
you to lose control of the equipment. If you must enter in such areas, use a tractor with an
enclosed Cab and close the windows to prevent insects from entering. If a tractor cab is not
available, wear suitable clothing including head, face, and hand protection to shield you from the
insects. Attacking insects can cause you to lose control of the tractor, which can result in serious
injury or death to you or bystanders. Never dismount a movingtractor. (SG-40)
Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting.
Never mow in darkness or foggy conditions where you cannot clearly see at least 100 yards in
front and to the sides of the tractor and mower. Make sure that you can clearly see and identify
passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and
foreign objects. If you are unable to clearly see these type of items discontinue mowing. (SGM-1)
There are obvious and hidden potential hazards in the operation of this Mower.
REMEMBER! This machine is often operated in heavy brush and in heavy
weeds. The Blades of this Mower can throw objects if shields are not properly
installed and maintained. Serious injury or even death may occur unless care
is taken to insure the safety of the operator, bystanders, or passersby in the
area. Do not operate this machine with anyone in the immediate area. Stop
mowing if anyone is within 100 yards of mower. (SGM-2)
The rotating parts of this machine have been designed and tested for rugged use. However, the
blades could fail upon impact with heavy, solid objects such as metal guard rails and concrete
structures. Such impact could cause the broken objects to be thrown outward at very high
velocities. To reduce the possibility of property damage, serious injury, or even death, never allow
the cutting blades to contact such obstacles. (SGM-4)
Extreme care should be taken when operating near loose objects such as
gravel, rocks, wire, and other debris. Inspect the area before mowing.
Foreign objects should be removed from the site to prevent machine damage
and/or bodily injury or even death. Any objects that cannot be removed must
be clearly marked and carefully avoided by the operator.
Stop mowing
immediately if blades strike a foreign object. Repair all damage and make
certain rotor or blade carrier is balanced before resuming mowing. (SGM-5)

SE4 05/05

Safety Section 1-8

SAFETY
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating
parts of the mower head. These items could then swing outside the housing at greater velocities
than the blades. Such a situation is extremely hazardous and could result in serious injury or
even death. Inspect the cutting area for such objects before mowing. Remove any like object
from the site. Never allow the cutting blades to contact such items. (SGM-6)

Follow these guidelines to reduce the risk of equipment and grass fires while
operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accesible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage and
plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and
gearboxes. Periodically shut down the Tractor and Mower and clean clippings
and collected debris from the mower deck. (SGM-12)
The Mower is designed for certain mowing applications and is rated to cut up to a specific size
vegetation (see Mower Standard Equipment and Specifications). DO NOT use this mower to cut
vegetation above the Mower’s rated capacity or to cut any type of non-vegetative material. Only
operate this Mower on a properly sized and equipped Tractor. Operating this Mower in an
application for which it is not designed and/or operating the Mower with the wrong size Tractor can
cause Mower component damage and equipment failure resulting in possible serious injury or
death. (SGM-14)

SE4 05/05
© 2005 Alamo Group Inc.

Safety Section 1-9

SAFETY

Mow at the speed that you can safely operate and control the tractor and mower. Safe mowing
speed depends on terrain condition and grass type, density, and height of cut. Normal ground
speed range is from 0 to 5 mph. Use slow mowing speeds when operating on or near steep
slopes, ditches, drop-offs, overhead obstructions, power lines, or when debris and foreign objects
are to be avoided. (SGM-7)

SAFETY
Do not operator or pull the mower into standing water. When uplift or fan type mower blades
contact water they can be severely deflected downward causing possible failure of blade
resulting in serious boldly injury to the operator or bystanders.

(SGM-15)

SAFETY

Use extreme caution when raising the Mower above ground level. Stop the Blades from
turning when the Mower is raised and passersby are within 100 yards. Raising the Mower
exposes the Cutting Blades which creates a potentially serious hazard and can cause serious
injury by objects thrown from the Blades or by contact with the Blades. (SPU-1)

Rotary Mowers are capable under adverse conditions of throwing objects for
great distances (100 yards or more) and causing serious injury or death.
Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good,
workable condition;
-Mower sections or Wings are running close to and parallel to the ground
without exposed Blades;
-Passersby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material such as
rocks, cans, glass, and general debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that
could be struck by the blades, the area should be: inspected and large debris
removed, mowed at an intermediate height, inspected, closely with any
remaining debris being removed, and mowed again at desired final height.
(This will also reduce power required to mow, reduce wear and tear on the
Mower drivetrain, spread cut material better, eliminate streaking, and make the
final cut more uniform). (SRM-1)
Do Not attempt to raise or lower the implement wing unless the Implement tongue is securely attached to
the Tractor drawbar. The Implement could tip over and cause equipment damage and possible serious
injury or death. Raise or Lower the mower wing only while seated in the Tractor operator’s seat with the
seat belt securely fastened. (SRM-2)

SE4 05/05

Safety Section 1-10

SAFETY
Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline which
will cause accelerated wear and breakage of drive train components and could result in possible
injury from the separated Driveline sections. (SRM-4)
Do not let the Blades turn when the Mower Deck is raised for any reason,
including clearance or for turning. Raising the Mower deck exposes the Cutting
Blades which creates a potentially serious hazard and could cause serious
injury or even death from objects thrown from the Blades. (SRM-7)

DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor PTO. Use
of an adapter can double the operating speed of the Mower resulting in excessive vibration,
thrown objects, and blade and mower failure. Adapter use will also change the working length of
the driveline exposing unshielded driveline areas. Serious bodily injury and/or equipment failure
can result from using a PTO adapter. Consult an authorized dealer for assistance if the
Implement driveline does not match the Tractor PTO. (S3PT-14)
Always shut the Tractor completely down, place the transmission in park, and set the parking
brake before you or anyone else attempts to connect or disconnect the Implement and Tractor
hitches. (S3PT-15)

Never operate the Tractor and Mower if the Implement input driveline is directly connected to the
Tractor transmission. Tractor braking distances can be substantially increased by the momentum
of the rotating Mower blades driving the Tractor transmission even though the Tractor clutch has
been disengaged. Install an over running clutch between the Tractor PTO and the Mower
driveline to prevent this potentially dangerous situation. (S3PT-16)
When attaching the Implement input driveline to the Tractor PTO, it is important that the
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. A driveline not attached correctly to the Tractor
PTO shaft could come loose and result in personal injury and damage to the Implement. (S3PT-17)
Before operating the Implement, check to make sure the Implement input driveline will not bottom
out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer
housing until the assembly becomes solid-it can shorten no more. Bottoming out can cause
serious damage to the Tractor PTO by pushing the PTO into the Tractor and through the support
bearings or downward onto the PTO shaft, breaking it off. A broken drive line can cause personal
injury. (S3PT-18)

Transporting Safety Instructions and Practices

SAFETY

Be particularly careful when transporting the Implement with the Tractor. Turn curves or go up hills
only at a low speed and using a gradual steering angle. Rear mounted implements move the
center of gravity to the rear and remove weight from the front wheels. Make certain, by adding
front ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up,
loss of steering control or Tractor tip-over. Slow down on rough or uneven surfaces to prevent
loss of steering control which could result in property damage or possible injury. Do not transport
unless 3-Point lift lever is fully raised and in the latched transport position. Dropping implement in
transport can cause serious damage to the tractor and/or Implement and possibly cause the
operator or others to be injured or killed. (S3PT-2)
Allow sufficient clearance for the Implement to swing outward while turning. Implements carried
behind the Tractor will swing outside the tire path when making turns. Contacting a solid object
while turning will cause equipment damage and possible injury. (S3PT-20)

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in such a
way as to be clearly visible and legible. When transporting the Equipment use
the Tractor flashing warning lights and follow all local traffic regulations. (SG-6)

SAFETY
Transport only at safe speeds. Serious accidents and injuries can result from
operating this equipment at unsafe speeds. Understand the Tractor and
Implement and how it handles before transporting on streets and highways.
Make sure the Tractor steering and brakes are in good condition and operate
properly.
Before transporting the Tractor and Implement, determine the safe transport
speeds for you and the equipment. Make sure you abide by the following rules:

•

Be aware of the operating conditions. Do not operate the Tractor with weak or
faulty brakes. When operating down a hill or on wet or rain slick roads, the
braking distance increases: use extreme care and reduce your speed. When
operating in traffic always use the Tractor’s flashing warning lights and reduce
your speed. Be aware of traffic around you and watch out for the other guy.
(SG-19)

Be particularly careful when transporting the Implement using the tractor. Turn curves or go up or
down hills only at a low speed and at a gradual steering angle. Make certain that at least 20% of
the tractor’s weight is on the front wheels to maintain safe steerage. Slow down on rough or
uneven surfaces. (STI-1)
Only tow the Implement behind a properly sized and equipped Tractor which
exceeds the weight of the Implement by at least 20%. DO NOT tow the
Implement behind a truck or other type of vehicle. Never tow the Implement
and another Implement connected in tandem. Never tow the Implement at
speeds over 20 MPH. (STI-6)

Safety Section 1-13

SAFETY

•

Test the tractor at a slow speed and increase the speed slowly. Apply
the Brakes smoothly to determine the stopping characteristics of the
Tractor and Implement. As you increase the speed of the Tractor the
stopping distance increases. Determine the maximum safe transport
speed for you and this Equipment.
Test the equipment at a slow speed in turns. Increase the speed
through the turn only after you determine that it is safe to operate at a
higher speed. Use extreme care and reduce your speed when turning
sharply to prevent the tractor and implement from turning over.
Determine the maximum safe turning speed for you and this equipment before operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds that you have
determined are safe and which allow you to properly control the
equipment.

SAFETY
Your driving vision may be reduced or impaired by the tractor, cab, or implement. Before driving
on public roadways identify any limited vision areas, and make adjustments to your operating
position, mirrors, and the implement transport position so that you can clearly see the area where
you will be traveling, and any traffic that may approach you. Failure to maintain adequate vision of
the public roadway and traffic can result in serious injury or even death. (STI-10)

Maintenance and Service Safety Instructions and Practices

SAFETY

Make sure the PTO shield, integral driveline shields, and input shields are is
installed when using PTO-driven equipment. Always replace any shield if it is
damaged or missing. (S3PT-8)
Relieve hydraulic pressure prior to doing any maintenance or repair work on
the Implement. Place the Implement on the ground or securely blocked up,
disengage the PTO, and turn off the tractor engine. Push and pull the Remote
Cylinder lever in and out several times prior to starting any maintenance or
repair work. (S3PT-9)
Always disconnect the main PTO Driveline from the Tractor before performing service on the
Implement. Never work on the Implement with the tractor PTO driveline connected and running.
Rotating Parts, Blades or Drivelines could turn without warning and cause immediate
entanglement, injury or death. (S3PT-11)
Never interfere with factory-set hydraulic calibrations. Any change in calibration could cause a
failure of the equipment and may result in injury. (SBH-13)

Always maintain the safety decals in good readable condition. If the decals are missing,
damaged, or unreadable, obtain and install replacement decals immediately. (SG-5)

Do not modify or alter this Implement. Do not permit anyone to modify or alter this Implement,
any of its components or any Implement function. (SG-8)

Never work under the Implement, the framework, or any lifted component
unless the Implement is securely supported or blocked up to prevent sudden or
inadvertent falling which could cause serious injury or even death. (SG-14)

Safety Section 1-14

SAFETY
Never attempt to lubricate, adjust, or remove material from the Implement while it is in motion or
while tractor engine is running. Make sure the tractor engine is off before working on the
Implement. (SG-20)

Periodically inspect all moving parts for wear and replace when necessary with
authorized service parts. Look for loose fasteners, worn or broken parts, and
leaky or loose fittings. Make sure all pins have cotter pins and washers.
Serious injury may occur from not maintaining this machine in good working
order. (SG-21)

SAFETY
Do Not fill gasoline tank while engine is running. Refuel only after engine has cooled down. If
gasoline is spilled, move machine away from the area of the spill and avoid creating any source of
ignition until the gasoline has evaporated. (SG-28)
Perform service, repairs and lubrication according to the maintenance section. Ensure the unit is
properly lubricated as specified in the lubrication schedule and all bolts and nuts are properly
torqued. Failure to properly service, repair and maintain this Implement in good operating
condition could cause component failure and possible serious injury or even death. (SG-35)
Use caution and wear protective gloves when handling sharp objects such as blades, knives, and
other cutting edges. Be alert to worn component surfaces which have sharp edges. Sharp
surfaces can inflict severe laceration injuries if proper hand protection is not worn. (SG-37)

All Safety Shields, Guards and Safety devices including (but not limited to)
- the Deflectors, Chain Guards, Steel Guards, Gearbox Shields, PTO
integral shields, and Retractable Door Shields should be used and
maintained in good working condition. All safety devices should be
inspected carefully at least daily for missing or broken components.
Missing, broken, or worn items must be replaced at once to reduce the
possibility of injury or death from thrown objects, entanglement, or blade
contact. (SGM-3)
Replace bent or broken blade with new blades. NEVER ATTEMPT TO STRAIGHTEN OR WELD
ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE BLADE

INTRODUCTION

INTRODUCTION
Your RHINO SE4 & 42 mower is designed for light-duty cutting such as pasture mowing, weed, and grass
control. With a reasonable amount of preventive maintenance, your Mower will provide years of dependable
service.
For Non-Agricultural use, OSHA, ASAE, SAE, and ANSI standards require the use of Chain
Guards or Solid Skirts at all times. The Cutter manufacturer strongly recommends the use of
Chain Guards or Solid Skirts for Agricultural purposes as well, to reduce the risk of property
damage, serious bodily injury, or even death from objects thrown out by or from contact with the
Cutting Blades.
At least 20% or the tractor’s weight must be on the front tires with the implement lifted to provide
adequate traction for safe steering under good conditions. Slow down on hills, rough terrain,
and curves.

Front and rear, and left and right are determined by the normal direction of travel (the same as on your
automobile).

OPERATION
2.3 Tractor Horsepower

OPERATION

The horsepower required to operate the mower depends on several operating factors including the vegetation
to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most
mowing conditions, the CY60 mower requires a tractor with a minimum of 30 HP and the CY72 mower requires
a tractor with a minimum of 40 HP. Operating the mower with a tractor that does not have adequate power may
damage the tractor engine. Exceeding 75 HP may cause mower damage by overpowering the unit in heavy
cutting conditions.

2.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least
435 lbs.
The SE4 mower is designed to be mounted on a
tractor with a CAT I 3-point hitch. Refer to the
tractor operator’s manual for the category of the
tractor being used. If the hitch does not conform to
ASAE CAT I dimensions, the mower may not fit or
raise properly. Consult an authorized dealer for
possible modification procedures to mount nonconforming hitches.
Depending on the hitch category, certain size pins
are used to attach the mower to the tractor. CAT I hitches require 7/8” lower and 3/4” upper diameter hitch
pins.
CAT I Implement / Hitch Specification
Width from outside to outside A-frame.... 26 7/8”
Quick Hitch width inside lug to lug ......... 27 1/8”
Height from bottom hitch pin to top pin ... 18”
Lower pin diameter ................................. 7/8”
Upper pin diameter ................................ 3/4”
Lynch pin diameter ................................. 15/32”

2.5 Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end
weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the
front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front
weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005

SE4 05/05
© 2005 Alamo Group Inc.

Operation Section 4-6

OPERATION
2.6 Power Take Off (PTO)
Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors
operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the
mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft.
Those operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline
shaft. Note: The mower will not operate on tractors equipped with a 1000 RPM 20-spline, 1-3/4” shaft. Refer
to the tractor owner’s manual for instructions to change PTO speeds on models that operate at more than one
speed.

DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor PTO. Use
of an adapter can double the operating speed of the Mower resulting in excessive vibration,
thrown objects, and blade and mower failure. Adapter use will also change the working length of
the driveline exposing unshielded driveline areas. Serious bodily injury and/or equipment failure
can result from using a PTO adapter. Consult an authorized dealer for assistance if the
Implement driveline does not match the Tractor PTO. (S3PT-14)
Never operate the Tractor and Mower if the Implement input driveline is directly connected to the
Tractor transmission. Tractor braking distances can be substantially increased by the momentum
of the rotating Mower blades driving the Tractor transmission even though the Tractor clutch has
been disengaged. Install an over running clutch between the Tractor PTO and the Mower
driveline to prevent this potentially dangerous situation. (S3PT-16)

3. GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the implement and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for
a complete explanation. OPS-U- 0007
Do not mount the Tractor while the tractor is moving. Mount the Tractor only
when the Tractor and all moving parts are completely stopped. (SG-12)

SE4 05/05
© 2005 Alamo Group Inc.

Operation Section 4-7

OPERATION

If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an
over-running clutch must be used between the PTO output shaft and the driveline of the mower. An
authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006

OPERATION
3.1 Boarding the Tractor
Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control
levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt
around you.

OPERATION

Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be
seriously injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra
riders at all times. OPS-U- 0008
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and responsible
can operate the implement with adult supervision, if they have read and
understand the Operator’s Manuals, been trained in safe operation of the
tractor and Implement, and are physically large enough to reach and operate
the controls easily. (SG-11)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)

3.2 Dismounting the Tractor
Before dismounting, park the tractor and implement on a reasonably level surface, apply the parking brake,
idle the engine down, disengage the PTO, and lower the implement to the ground. Shut down the tractor
engine according to the operator’s manual, remove the key, and wait for all motion to completely stop. Never
leave the seat until the tractor, its engine and all moving parts have come to a complete stop.
Use hand rails and steps when exiting the tractor. Be careful of your step and use extra caution when mud,
ice, snow or other matter has accumulated on the steps or hand rails. Use all handrails and steps for support
and never rush or jump off the tractor. OPS-U- 0009
BEFORE leaving the tractor seat, always engage the brake and/or set the
tractor transmission in parking gear, disengage the PTO, stop the engine,
remove the key, and wait for all moving parts to stop. Place the tractor shift
lever into a low range or parking gear to prevent the tractor from rolling. Never
dismount a Tractor that is moving or while the engine is running. Operate the
Tractor controls from the tractor seat only. (SG-9)

Operation Section 4-8

OPERATION
4. STARTING THE TRACTOR
The operator must have a complete understanding of the placement, function, and operational use of all
tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized
dealer for tractor operation instructions if needed.
Essential Tractor Controls:

• Conduct all pre-start operation inspection and service according to the tractor operator’s manual.
• Make sure all guards, shields, and other safety devices are securely in place.
• The parking brake is on.
• The PTO control lever is disengaged.
• The 3-point hitch control lever is in the lowered position.
• The hydraulic remote control levers are in the neutral position.
• The tractor transmission levers are in park or neutral.
Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and
belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.
After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden
and unexpected tractor movement. OPS-U-0028
Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust
fumes can be hazardous to your health. (SG-23)

Start tractor only when properly seated in the Tractor seat. Starting a tractor in
gear can result in injury or death. Read the Tractor operators manual for proper
starting instructions. (SG-13)

5. CONNECTING THE MOWER TO THE TRACTOR
Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at
ground level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points
between the tractor hitch arms and mower pins. OPS-R-0001

Make sure the tractor is equipped with the
correct PTO shaft. Change shafts if needed.
Shorten or remove the tractor drawbar to
avoid interference when raising and lowering
the mower.
Board the tractor and start the engine. Position the tractor to the mower with the 3-point
lift arms positioned between the respective
set of mower A-frame lift lugs. Note: Set the
3-point lift control to “Position Control” so that
the lift arms maintain a constant height when
attaching the mower. See the tractor Operator’s Manual for correct settings when attaching 3-point equipment.
Turn off the tractor engine and dismount.
One lift arm at a time, align arm end hole
between the set of A-frame lift lugs. Insert
hitch pin through the lug and arm holes and
insert retaining pin into hitch pin.
Walk around to opposite side and repeat procedure for remaining lift arm and hitch pin.
Extend or retract 3-point top link to align its
end hole with the holes of the mower’s top
link. Insert the top link hitch pin and insert
retaining pin into hitch pin.
Adjust any lower link check chains, guide
blocks, or sway blocks to prevent the mower
from swaying side to side and possible contact with tractor rear tires.

Note: Offset Adaptor Hitches are available to position the mower to the left or right. Mowers with Offset
Adaptor hitches connect to the 3-Point hitch the same way as the mower A-frame. See Offset Adaptor Hitch in
the Assembly Section for details to equip the mower with this feature.

6. SETTING THE MOWER
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make
a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of
uneven terrain. NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most
damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may
cause objects to be thrown out from under the mower deck. Always avoid operating the mower at a height
which causes the blades to contact the ground. OPS-U- 0010

SE4 05/05

Operation Section 4-10

OPERATION
Never work under the Implement, the framework, or any lifted component
unless the Implement is securely supported or blocked up to prevent sudden or
inadvertent falling which could cause serious injury or even death. (SG-14)

6.1 Setting Mower Height

3.
4.

6.
7.

Park the tractor and mower on level ground.
Using the 3-point hitch control lever, position
the front of the mower with the side skids 1”
less off the ground than desired cut height.
For example, for a 3” cut, position the skids 2”
from the ground. Set the 3-point control lever
stop at this position to maintain this height
when raising and lowering the mower.
Shut down the tractor and remove the key.
Level the mower deck front to rear by
extending or retracting the 3-point top link.

Level the mower side to side by manipulating
one lower lift arm length. On most tractors, at
least one of the lift arms is designed to allow
for manipulation of its length. Shortening or
extending will allow for deck leveling from
side to side.
Securely block up the mower at this height.
Remove the bolts securing the tailwheel
beam positioning bracket to the support
brackets and allow the tailwheel to rest at
ground level. Align beam and positioning
brackets holes with closest set of holes in
support brackets and reinstall bolts securing
the beam in position. Tighten all bolts and
nuts.
Extend the tractor’s top 3-point link so that
when lifting the mower, the front of the deck
will raise 2 to 2½" before the tail wheel leaves
the ground. This will allow the mower to
follow the contour of uneven terrain.

Note: Install optional check chains when there is a
problem with the hydraulic 3-Point lift maintaining a
set height or when a constant pre-adjusted cut
height is required. See Check Chains in the
Assembly Section for this accessory.

OPERATION
6.2 Setting Deck Pitch

OPERATION

To facilitate safe and efficient operation, the mower
should be operated with the deck approximately
3/4” LOWER IN THE FRONT THAN THE REAR.
Operating the mower at this pitch will allow the
mower to cut the grass only once and requires less
work from the tractor. In addition, a more even
distribution of the clippings from the rear of the
mower will be achieved with this deck pitch.
Adjust the leveling rods linking the tongue to the
rear axle until the front of the mower is at least 3/4”
lower in the front that than the rear. To lower the
front, lengthen the leveling rods and to raise the
front shorten the leveling rods. IMPORTANT: Adjust the leveling rods the same amount and maintain equal
tension in the rods. Improper adjustment may cause rods to snap or bend. Retighten the jamnuts after the
deck pitch has been set. OPS-R-0002

7. DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be
dirt free and greased for attachment.
To connect the mower driveline to the tractor PTO
output shaft, pull the driveline yoke collar back and
align the grooves and splines of the yoke with those
of the PTO shaft. Push the driveline yoke onto the
PTO shaft, release the locking collar, and position
the yoke until the locking collar balls are seated
onto the PTO shaft. Push and pull the driveline
back and forth several times to ensure a secure
attachment.
After the driveline is securely attached, place the
tractor PTO master shield back in the operating position. OPS-R-0003
When attaching the Implement input driveline to the Tractor PTO, it is important that the
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. A driveline not attached correctly to the Tractor
PTO shaft could come loose and result in personal injury and damage to the Implement. (S3PT-17)

SE4 05/05

Operation Section 4-12

OPERATION
7.1 Driveline Length Check
Before operating the Implement, check to make sure the Implement input driveline will not bottom
out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer
housing until the assembly becomes solid-it can shorten no more. Bottoming out can cause
serious damage to the Tractor PTO by pushing the PTO into the Tractor and through the support
bearings or downward onto the PTO shaft, breaking it off. A broken drive line can cause personal
injury. (S3PT-18)

“Bottoming Out” Check Procedure
•
•
•
•

Disconnect driveline from the tractor and slide
the profiles together until fully compressed.
Place a mark on the inner shield 1/8” from the
end of the outer shield.
Reattach the driveline to the PTO Shaft.
Raise the mower and watch the driveline as it
approaches the mark. If the distance between
the mark and the end of the outer shield tube
becomes less than 2” at any point, the driveline
must be shortened. OPS-R-0004_A

SE4 05/05
© 2005 Alamo Group Inc.

Operation Section 4-13

OPERATION

When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most
compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is
sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1”
clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a
minimum profile engagement of 10” must be maintained.

OPERATION
Shorten the driveline profiles as follows:
•
•

OPERATION

•
•

•
•
•

Remove the driveline from the tractor.
Position the mower to the point with the
shortest distance between the tractor PTO
shaft and cutter gearbox. Shut down the tractor
and securely block the mower in this position.
Pull driveline apart and reattach yoke to PTO
shaft.
Hold driveline sections parallel to one another
and measure back 1” from yoke of each shaft
and place mark on opposite section. Cut this
length off with a saw.
Round off all sharp edges and debur.
Thoroughly grease then reinstall the driveline.
Recheck for proper operation.

Engagement Check Procedure
•

With the driveline attached, position the mower to the point where the telescoping driveline is at its
maximum extension. Completely shut down the tractor and secure in position.
• Mark the inner driveline shield 1/8” from the end of the outer shield.
• Disconnect the driveline from the tractor and separate the two driveline halves.
• Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline
profiles were engaged.
• If the engaged length is less than 12” for a CV driveline and less than 6” for a non-CV driveline, the shaft is
considered too short and should be replaced with a longer shaft. Consult an authorized dealer to
purchase the required driveline length.
NOTE: If the driveline cannot be shortened and still maintain the required profile engagement, the operator
must be made aware of terrain conditions and avoid situations which pose a potential problem to avoid
damaging the driveline. OPS-R-0005

8. PRE-OPERATION INSPECTION AND SERVICE
Before each use, a pre-operation inspection and service of the implement and tractor must be performed.
This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped
and functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection
reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing
parts as soon as noticed. By performing a thorough pre-operation inspection and service, valuable down time
and repair cost can be avoided. OPS-U-0029
Always disconnect the main PTO Driveline from the Tractor before performing service on the
Implement. Never work on the Implement with the tractor PTO driveline connected and running.
Rotating Parts, Blades or Drivelines could turn without warning and cause immediate
entanglement, injury or death. (S3PT-11)

death. OPS-U-0032

OPERATION
Transport only at safe speeds. Serious accidents and injuries can result from
operating this equipment at unsafe speeds. Understand the Tractor and
Implement and how it handles before transporting on streets and highways.
Make sure the Tractor steering and brakes are in good condition and operate
properly.
Before transporting the Tractor and Implement, determine the safe transport
speeds for you and the equipment. Make sure you abide by the following rules:

OPERATION

•

Test the tractor at a slow speed and increase the speed slowly. Apply the
Brakes smoothly to determine the stopping characteristics of the Tractor
and Implement. As you increase the speed of the Tractor the stopping
distance increases. Determine the maximum safe transport speed for you
and this Equipment.
Test the equipment at a slow speed in turns. Increase the speed through
the turn only after you determine that it is safe to operate at a higher speed.
Use extreme care and reduce your speed when turning sharply to prevent
the tractor and implement from turning over. Determine the maximum safe
turning speed for you and this equipment before operating on roads or
uneven ground.
Only transport the Tractor and Implement at the speeds that you have
determined are safe and which allow you to properly control the equipment.

9.1 Starting the Tractor
The procedure to start the tractor is model specific.
Refer to the tractor operator’s manual for starting
procedures for your particular tractor. Consult an
authorized dealer if the starting procedure is
unclear. Ensure the 3-point control lever is in the
lowered position and the PTO is disengaged before
starting the tractor. OPS-U-0033

SE4 05/05
© 2005 Alamo Group Inc.

Operation Section 4-20

OPERATION
9.2 Brake and Differential Lock Setting

Always disengage the tractor differential lock when
turning. When engaged the differential lock will
prevent or limit the tractor from turning. During
normal cutting conditions, locking the differential
provides no benefit and should not be used. OPS-U- 0013

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
When operating down a hill or on wet or rain slick roads, the braking distance increases; use
extreme care and reduce your speed in these conditions. When operating in traffic, always use
the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you and
watch out for the other guy.

9.3 Raising the Mower
Using the tractor 3-point hitch control lever, raise
the mower off the ground about 6”, or just high
enough to clear any ground obstacles. When
raising the mower, make sure all connection points
are securely attached and at least 1” clearance is
maintained between the driveline and the deck. If
necessary, place an upper lift stop on the 3-point
hitch control lever to limit the height the mower can
be raised to avoid driveline damage. OPS-R-0042

SE4 05/05

Operation Section 4-21

OPERATION

Make sure the tractor brakes are in good operating
condition. Tractor brakes can be set to operate
independently allowing single rear wheel braking
action or locked together to provide simultaneous
rear wheel braking. FOR MOST DRIVING AND
OPERATING CONDITIONS, THE BRAKE PEDALS
SHOULD BE LOCKED TOGETHER TO PROVIDE
THE MOST EFFECTIVE BRAKING ACTION.

OPERATION
9.4 Driving the Tractor and Mower

OPERATION

Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the
tractor and mower. Moving slowly at first will also prevent the tractor from rearing up and loss of steering
control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent
the operator from stopping quickly during an emergency. If the power steering or engine ceases operating,
stop the tractor immediately as the tractor will be difficult to control.
Perform turns with the tractor and mower at slow
speeds to determine how the tractor with an
attached mower handles a turn. Determine the
safe speed to maintain proper control of the tractor
when making turns. When turning with a towed
implement, the overall working length of the unit is
increased.
Allow additional clearance for the
mower when turning.
To avoid overturns, drive the tractor with care and
at safe speeds, especially when operating over
rough ground, crossing ditches or slopes, and
turning corners.
Tractor wheel tread spacing
should be increased when working on inclines or
rough ground to reduce the possibility of tipping.
Use extreme caution when operating on steep
slopes. Keep the tractor in a low gear when going
downhill. DO NOT coast or free-wheel downhill.
OPS-R-0019
Be particularly careful when transporting the Implement with the Tractor. Turn curves or go up hills
only at a low speed and using a gradual steering angle. Rear mounted implements move the
center of gravity to the rear and remove weight from the front wheels. Make certain, by adding
front ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up,
loss of steering control or Tractor tip-over. Slow down on rough or uneven surfaces to prevent
loss of steering control which could result in property damage or possible injury. Do not transport
unless 3-Point lift lever is fully raised and in the latched transport position. Dropping implement in
transport can cause serious damage to the tractor and/or Implement and possibly cause the
operator or others to be injured or killed. (S3PT-2)

OPERATION
9.5 Crossing Ditches and Steep Inclines

Damage resulting from over-collapse of the driveline’s inner profile and its outer housing may
allow the driveline to come loose from the Tractor which could cause bodily injury to the operator
or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020
When confronted with an incline or ditch, do not
approach from an angle which is perpendicular or
straight on as damage to over collapse of the
driveline may occur.
When crossing such terrain, the wings should be
fully lowered for a lower center of gravity and added
stability. OPS-R-0021

SE4 05/05
© 2005 Alamo Group Inc.

Operation Section 4-23

OPERATION

When crossing ditches with steep banks or going
up sharp inclines, it is possible that the main
driveline inner profile will penetrate into the outer
housing to its maximum depth until the assembly
becomes solid (driveline is at its extreme shortest
length). This type of abusive operation can cause
serious damage to the tractor and mower drive by
pushing the PTO into the tractor and through the
support bearings or downward onto the PTO shaft,
breaking it off.

OPERATION

Inclines and ditches should be approached along a
line which is at an angle as shown. This type of
path will reduce the possibility of over-collapse of
the driveline and resulting damage. If the gradient
is so steep that such as approach increases the
possibility of a tractor roll-over, select an alternate
crossing path.
When operating the tractor and mower across
slopes and inclines, through ditches, and other
uneven terrain conditions, it is important to maintain
sufficient deck to ground clearance. Blade contact
with the ground may cause soil, rocks and other
debris to be thrown out from under the mower
resulting in possible injury and/or property damage.
Ground contact also produces a severe shock load
on the mower drive and to the mower blades
resulting in possible damage and premature wear.
OPS-R-0022

10. OPERATING THE TRACTOR AND IMPLEMENT
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND
IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and
understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These
manuals must be read and explained to any operator who cannot read. Never allow someone to operate the
implement and tractor without complete operating instructions.
Before starting any operation, the operator must become familiar with the area to be worked in and any
obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special
attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.
OPS-U- 0015
Extreme care should be taken when operating near loose objects such as
gravel, rocks, wire, and other debris. Inspect the area before mowing.
Foreign objects should be removed from the site to prevent machine damage
and/or bodily injury or even death. Any objects that cannot be removed must
be clearly marked and carefully avoided by the operator.
Stop mowing
immediately if blades strike a foreign object. Repair all damage and make
certain rotor or blade carrier is balanced before resuming mowing. (SGM-5)

SE4 05/05
© 2005 Alamo Group Inc.

Operation Section 4-24

OPERATION
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating
parts of the mower head. These items could then swing outside the housing at greater velocities
than the blades. Such a situation is extremely hazardous and could result in serious injury or
even death. Inspect the cutting area for such objects before mowing. Remove any like object
from the site. Never allow the cutting blades to contact such items. (SGM-6)

10.1 Foreign Debris Hazards

If you hit a solid object or foreign debris, stop the
mower and tractor at once. Immediately idle the
engine speed and disengage the PTO. Wait for all
mower rotating motion to stop, then raise the
mower and move the tractor and implement off the
object. Inspect the area and remove, or mark the
location of the debris. Inspect the condition of the
mower and make any needed repairs immediately.
Make sure the blades are not damaged and the
carrier is balanced before resuming operation.
Always wear your seat belt securely fastened and
only operate the tractor and mower with the ROPS
in the raised position. If the tractor or mower hits a
tree stump, rock, or bump, a sudden movement
could throw you off of the seat and under the
tractor and/or mower. The seat belt is your best
protection from falling off the tractor and the ROPS
provides protection from being crushed during a
tractor roll-over. OPS-R-0023

10.2 Bystanders/Passersby Precautions
If a bystander comes within 100 yards of the tractor while the mower is being operated, stop the tractor at
once, idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past
the 100 yard distance. OPS-R-0024

SE4 05/05
© 2005 Alamo Group Inc.

Operation Section 4-25

OPERATION

Before mowing, inspect the area to make sure
there are no foreign objects that the mower blades
could hit or become entangled with. Remove all
foreign objects and debris. If objects are too big to
remove, mark them clearly and be sure to prevent
the mower blades from contacting them.

OPERATION
Rotary Mowers are capable under adverse conditions of throwing objects for
great distances (100 yards or more) and causing serious injury or death.
Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good,
workable condition;

OPERATION

-Mower sections or Wings are running close to and parallel to the ground
without exposed Blades;
-Passersby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material such as
rocks, cans, glass, and general debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that
could be struck by the blades, the area should be: inspected and large debris
removed, mowed at an intermediate height, inspected, closely with any
remaining debris being removed, and mowed again at desired final height.
(This will also reduce power required to mow, reduce wear and tear on the
Mower drivetrain, spread cut material better, eliminate streaking, and make the
final cut more uniform). (SRM-1)

10.3 Engaging the Power Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement
must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with
the implement in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to
the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you
hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the
implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027
Do not let the Blades turn when the Mower Deck is raised for any reason,
including clearance or for turning. Raising the Mower deck exposes the Cutting
Blades which creates a potentially serious hazard and could cause serious
injury or even death from objects thrown from the Blades. (SRM-7)
Do not put hands or feet under mower decks. Blade Contact can result serious
injury or even death. Stay away until all motion has stopped and the decks are
securely blocked up. (SGM-9)

SE4 05/05

Operation Section 4-26

OPERATION
10.4 PTO RPM and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.
Recommended speed for efficient mower performance is between 2 and 5 mph. Operate the mower at its full
rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or the tractor
instrument panel for the engine speed and gear to provide the required PTO and desired ground speed.
Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut. If it
becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.

Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death. (SG-26)

10.5 Operating the Mower
Only operate the mower from the tractor operator’s seat with the seatbelt securely fastened. The tractor must
be equipped with a ROPS in the raised position or a ROPS cab.
The mower is designed to cut vegetation up to 1-1/2” in diameter. Sharp blades will produce a cleaner cut and
require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and
maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving pattern
that provides the maximum pass length and minimizes turning.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the
same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining
the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and
be cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut.
Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to
access areas to be cut, make sure there are no persons or other foreign debris behind the mower before
mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to
ensure tractor and mower control is maintained. OPS-R-0026

SE4 05/05
© 2005 Alamo Group Inc.

Operation Section 4-27

OPERATION

Ground speed is achieved by transmission gear selection and not by the engine operating speed. The
operator may be required to experiment with several gear range combinations to determine the best gear and
range which provides the most ideal performance from the mower and most efficient tractor operation. As the
severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to
maintain the proper operating PTO speed. OPS-R-0025

OPERATION
Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting.
Never mow in darkness or foggy conditions where you cannot clearly see at least 100 yards in
front and to the sides of the tractor and mower. Make sure that you can clearly see and identify
passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and
foreign objects. If you are unable to clearly see these type of items discontinue mowing. (SGM-1)

OPERATION

Avoid mowing in reverse direction when possible. Check to make sure there are no persons
behind the mower and use extreme care when mowing in reverse. Mow only at a slow ground
speed where you can safely operate and control the tractor and mower. Never mow an area that
you have not inspected and removed debris or foreign material. (SGM-8)
Follow these guidelines to reduce the risk of equipment and grass fires while
operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accesible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage and
plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and
gearboxes. Periodically shut down the Tractor and Mower and clean clippings
and collected debris from the mower deck. (SGM-12)
When you get to the end of a pass, slightly raise the
mower (2-4”) before turning. Never raise the
mower entirely while the blades are turning. If the
mower must be raised higher than 12” from ground
level, disengage the tractor PTO and wait for all
mower rotation to come to a complete stop before
proceeding to raise the mower.
When turning, the angle between the tractor and
mower should not be so great that a clattering of
the U-joints occurs.
Sharp turns can cause
premature failure of the joints and place pressure
on the tractor PTO shaft and could cause extensive
mechanical damage to the mower and tractor.

proceeding to drive or shut down the tractor.

Park the tractor on a level surface, place the
transmission in park or neutral and apply the
parking brake, lower the attached implement to the
ground, shut down the engine, remove the key, and
wait for all motion to come to a complete stop
before exiting the tractor. OPS-U- 0016

11. DISCONNECTING THE MOWER FROM THE TRACTOR
Before disconnecting the mower, the PTO must be
disengaged and blade rotation at a complete stop.
Move the mower to a level storage location and
lower it to the ground. If the mower is not resting
securely on the ground, block the mower up
securely before attempting to disconnect it from
the tractor.
Use extreme care to keep feet and hands from
under the mower and clear of any pinch points
caused by the tractor hitch arms and mower pins.

OPERATION
To disconnect the mower, first extend the tractor 3point hitch top link to remove tension on the top link
hitch pin. When the pin is loose and easy to rotate,
remove the pin from the mower. Next remove both
lower hitch pins..

Never stand or allow another person to stand between a running Tractor and the Mower when
disconnecting the Implement from the Tractor 3-point hitch.

Always shut the Tractor completely down, place the transmission in park, and set the parking
brake before you or anyone else attempts to connect or disconnect the Implement and Tractor
hitches. (S3PT-15)

Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift the
Tongue without using the Tongue Jack could cause strains or other injury. Allowing the tongue to
fall suddenly and unexpectedly could result in crushing injury. Use the Tongue Jack for lifting the
Implement only. Overloading the Tongue Jack can cause failure with possible serious bodily
injury or even death. (STI-4)

and shorten the life of the driveline.. OPS-R-0060

OPERATION
12. MOWER STORAGE
Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance
and to help ensure years of dependable service. The following are suggested storage procedures:
•

OPERATION

•
•
•

Thoroughly clean all debris off the mower to
prevent damage from rotting grass and
standing water.
Lubricate all mower grease points and fill
gearbox oil levels as detailed in the
maintenance section.
Tighten all bolts and pins to the recommended
torque.
Check the mower for worn and damaged
parts. Perform repairs and make
replacements immediately so that the mower
will be ready for use at the start of the next
season.
Store the mower in a clean, dry place with the
mower housing resting securely on blocks or
at ground level.
Keep the driveline yoke from sitting in water,
dirt and other contaminants.
Use spray touch-up enamel where necessary
to prevent rust and maintain the appearance
of the mower.

It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid mower and/or
tractor damage. If the mower sits outside for an extended period of time or is exposed to rain and/or humid
air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion. If
the mower has been exposed to such conditions, at the start of each mowing season, and any time it is
suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Seasonal
Clutch Maintenance of the maintenance section in this manual. OPS-R-0032_A
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)

13. TRANSPORTING THE TRACTOR AND IMPLEMENT
Inherent dangers of operating the tractor and implement and the possibility of accidents are not left behind
when you finish working in an area. Therefore, the operator must employ good judgement and safe operation
practices when transporting the tractor and implement between locations. By using good judgement and
following safe transport procedures, the possibility of accidents while moving between locations can be
substantially minimized. OPS-U- 0017

OPERATION

If the tractor’s hydraulic pump is not independent of
the tractor PTO, or if the tractor PTO has to be run
to have hydraulic power, disconnect the mower
driveline from the tractor PTO output shaft. Secure
the driveline to the mower deck to prevent driveline
damage or loss during transport. OPS-R-0034

13.1 Tire and Wheels
Laminated Sectional Tires are designed for conditions where puncture proof performance is required and
the mower will not be transported for long distances on roadways. Transport speed for laminated tires should
not exceed 10 MPH. Excessive speed can cause damage to the machine and tire sections. Sectional tires
must be installed such that the rubber segments lay with the ground. OPS-R-0035_A

13.2 Transporting on Public Roadways
Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor
must be equipped with all required safety warning features including a SMV emblem and flashing warning
lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for
automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.
Check your side view mirrors frequently and remember that vehicles will approach quickly because of the
tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than
the tractor tire width and/or extends beyond your lane of the road.
Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a
public road. OPS-U- 0019

mower moving parts to come to a complete stop.
Once all mower parts are completely stopped, raise
the mower to transport height. NOTE: When
raising the mower, maintain 1” clearance between
the driveline and mower deck. If additional mower
deck height is needed for safe transport, disconnect
the driveline from the tractor and secure its end to
the mower deck. The mower can then be raised to
the maximum lift height. OPS-R-0033_A

OPERATION

The SMV (Slow-Moving Vehicle) emblem is
universal symbol used to alert drivers of the
presence of equipment traveling on roadways at a
slow speed. SMV signs are a triangular bright
orange with reflective red trim for both easy day
and night visibility. Make sure the SMV sign is
clean and visible from the rear of the unit before
transporting the tractor and implement on a public
roadway. Replace the SMV emblem if faded,
damaged, or no longer reflective. OPS-U- 0020

Make sure that all tractor flashing warning lights,
headlights, and brake/tail lights are functioning
properly before proceeding onto public roads.
While newer model tractors have plenty of lighting
to provide warning signals and operating lighting,
most older models are only equipped with
operating lights. Consult an authorized tractor
dealer for lighting kits and modifications available to
upgrade the lighting on older tractor models.
OPS-U- 0021

When operating on public roads, have
consideration for other road users. Pull to the side
of the road occasionally to allow all following traffic
to pass. Do not exceed the legal speed limit set in

SHEAR PIN YOKE LUBRICATION
Yoke is supplied with a grease fitting to lube betweeen gearbox
shaft and yoke. This allows yoke to spin freely on gearbox shaft
when pin shears. Failure to lube may cause yoke to gall and spin
weld to shaft. Small amount of grease added every 5 (approx.)
shear pins will greatly prolong life of yoke.

BLADE SERVICING
Inspect blades before each use to determine that they are properly installed and in good condition. Replace
any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out
when sharpening.
Use only original equipment blades on this cutter. They are made of special heat-treated alloy
steel. Substitute blades may not meet specifications and may fail in a hazardous manner that
could cause injury.

Replace bent or broken blade with new blades. NEVER ATTEMPT TO STRAIGHTEN OR WELD
ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE BLADE WITH
SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM THROWN BLADES. (SGM-10)

BLADE SHARPENING
IMPORTANT! When sharpening blades, grind each blade the same amount to maintain balance. Follow
original sharpening pattern as shown in Figure Mnt-R-0008. Always sharpen blades by grinding. Always
sharpen both blades at same time to maintain balance. The difference in blade weights should not exceed 1
ounce. Unbalanced blades will cause excessive vibration which can damage gear box bearings. Vibration
may also cause structural cracks in cutter housing. DO NOT heat and pound out edge. Do not sharpen blade
to a razor edge, but leave a 1/16" blunt edge. Do not sharpen back side of blade.
Avoid personal injury. Always block the cutter up to prevent if from falling when the blades and/ or
carrier are being serviced.

Maintenance Section 5-5

MAINTENANCE

When attaching PTO yoke to tractor PTO shaft, it is important that spring-activated locking collar
slides freely and locking balls are seated in groove on PTO shaft. A loose shaft could slip off and
result in personal injury or damage to cutter.

MAINTENANCE
BLADE REMOVAL

MAINTENANCE

To remove blades for sharpening or replacement. Remove lock nut from blade bolt. NOTE: Inspect lock nut
after removal and replace if threads are damaged. Always replace nut when replacing blade bolt. When
installing blades be sure and check blade bolt pivot diameter for wear. Replace bolt if worn more than 1/4 inch
at any point. Tighten lock nut to 350 ft. lbs.
Avoid personal injury. Blade and/or blade carrier removal should be done only with the tractor
engine shut off, key removed, in neutral, parking brake on, and PTO disengaged and the cutter
blocked in the raised position.

BLADE CARRIER REMOVAL
Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered gearbox shaft. If gear puller is
not available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite
end of bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process.

BLADE CARRIER INSTALLATION
Clean the splines on both the blade carrier and output shaft. Position carrier on the gearbox output shaft and
install special washer nut.
Tighten nut holding blade carrier to minimum 350 ft. pounds, strike the carrier near the hub several times with a
heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads.
Retighten the nut to 350 ft. pounds. Install cotter pin and spread
IMPORTANT: Always recheck gearbox output shaft slotted blade carrier retaining nut torque after a few hours
operation.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from falling.

Maintenance Section 5-6

MAINTENANCE
STORAGE
Your rotary cutter represents an investment from which you should get the greatest possible benefit.
Therefore, when the season is over, the cutter should be thoroughly checked and prepared for storage so that
a minimum amount of work will be required to put it back into operation for the next season. The following are
suggested storage procedures:
Thoroughly clean the cutter.
Lubricate the cutter as covered in Maintenance Section.
Tighten all bolts and pins to the recommended torque.
Check the cutter for worn or damaged parts. Make replacements immediately.
Store the cutter in a clean, dry place with the cutter housing resting on blocks.
Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the
cutter.

PROPER TORQUE FOR FASTENERS
The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to
this chart to determine the grade of bolts and the proper torque except when specific torque values are
assigned in manual text.
RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THE MANUAL*
NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal engine
oil. They do not apply if special graphited or molydisulphide greases or other extreme pressure lubricants are
used. This applies to both UNF fine and UNC coarse threads.

pull complete shaft and housing assembly (See Fig. 8) out of main housing.
Remove 4 capscrews (Ref #18), break gasket loose, and then remove the bearing retainer cap (Ref
#2).
Output shaft assembly must be removed from main housing by driving or pulling shaft out bottom end.
NOTE: Once lower bearing is out of housing the complete assembly will drop down until top bearing
engages lower bearing bore. To complete removal of output shaft assembly it is necessary to keep
shaft aligned on center line of housing when removing top bearing out bottom end. Normally the
simplest method of removing the output shaft assembly is to attach a slide hammer puller to the shaft
and use that to pull the shaft out

inserted between bearing and gear before pressing bearing into housing.
SEAL INSTALLATION RECOMMENDATIONS
1.Check Seal - for damage that may have occurred prior to installation. A sealing lip that is turned
back, cut or otherwise damaged should be replaced.
2.Check Bore - to see that leading edge is deburred. A rounded corner or chamber should be
provided.
3.Check Shaft - remove surface nicks, burrs and grooves and lubricate with a hard, fibrous grease.
NOTE: Wrap plastic tape around irregular shaft surfaces such as splines to protect seal during
assembly.
4.Use Correct Installation Tool - Always use pipe or tube with approximate same OD as seal and press
seal by striking tube.
NEVER HAMMER DIRECTLY ON THE SURFACE OF THE SEAL.

Maintenance Section 5-9

MAINTENANCE

1.Remove snap ring (Ref. #11) and then remove bearing housing (Ref. #13) by holding end of shaft

so that housing will install completely.
2. Install washers and bolts and torque to 40-50 ft. lbs.
3.Gear backlash check procedure (Figure Mnt-R-0044). Install 1/2 x 3 capscrew through shear pin
hole. Install flat washers to take up 1/2" space and then install nut and tighten so bolt cannot move.
Clamp gearbox to something solid so it will not move when shaft is rotated by hand. Measure 1-1/2
inches from side of shaft to point on bolt and mark (See Figure Mnt-R-0044). Set dial indicator at
marked point, then while holding bottom shaft so it will not rotate, rotate the input shaft back and forth
noting extreme indicator reading. If total indicator deflection reading does not fall between .006 to
.018, then shims (Ref. #12 Figure Mnt-R-0040) will have to be added to increase backlash or deleted
to decrease backlash.

• IMPLEMENTS: I have explained that Deflectors, Chain Guards, or Solid Skirts must be maintained in good repair and installed except in areas where persons,
vehicles, livestock, or other property will not be endangered by thrown objects and where such safety equipment would prevent the mower’s reasonable performance
of its assigned task.
• DRIVELINES: I have made certain that all driveline, gearbox, and other shields are in good repair and fastened securely in place to prevent injuries from
entanglement or thrown objects.
•

HYDRAULIC MACHINES: I have explained the necessity of using clean hydraulic oil, changing filters as instructed, stopping leaks, damage caused by
operating with over-heated oil, caring for hoses, using hoses of proper rating, the necessity of maintaining the specified operating pressure, and the potential hazard
of oil's penetrating the skin.
