General Safety Instructions and Practices

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.

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)

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.

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)

Operator Safety Instuctions and Practices

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)

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

SE4 05/05 Safety Section 1-4

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)

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)

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 sur

aces 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)

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)

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 clothin

with the rotating elements can result in serious injury or even death. Stay clear of all rotatin

elements at all times. (SSP-3)

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 A-

Frame. Lower the implement carefully to the ground. Do not put hands or feet under lifted

components. (S3PT-1)

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 roll-

over-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)

SAFETY

SE4 05/05 Safety Section 1-7

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)

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)

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)

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)

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)

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)

Do not mow with two machines in the same area except with Cab tractors with the windows

closed. (SGM-11)

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)

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)

SAFETY

SE4 05/05 Safety Section 1-10

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)

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)

SAFETY

SE4 05/05 Safety Section 1-11

SAFETY

Connecting or Disconnecting Implement Safety Instructions and Prac-

tices

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)

connecting yoke spring activated locking collar slides freely and the locking balls are seated

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)

SAFETY

Transporting Safety Instructions and Practices

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 preven

loss of steering control which could result in property damage or possible injury. Do not transpor

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

SE4 05/05 Safety Section 1-13

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:

• 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 equip-

ment 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.

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 care

ul 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)

Maintenance and Service Safety Instructions and Practices

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 o

the public roadway and traffic can result in serious injury or even death. (STI-10)

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)

maintenance, and operating practices, as described in this manual, will help the owner/operator get years of

satisfactory service from the machine.

The purpose of this manual is to familiarize, instruct, and train. The Assembly Section instructs the owner/

operator in the correct assembly of the Cutter using standard and optional equipment. The Parts Listing

section is designed to familiarize the owner/operator with replaceable parts on the Cutter. This section

provides exploded assembly drawings of each Cutter component illustrating each piece and the corresponding

part number.

Careful use and timely service saves extensive repairs and costly downtime losses. The Operations and

Maintenance sections of the manual trains the owner/operator how to work the Cutter correctly and attend to

appropriate maintenance. The Trouble-Shooting Guide helps diagnose difficulties with the Cutter and offers

solutions to the problems.

Safety is of primary importance to the owner/operator and to the manufacturer. 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. Many of the Safety Messages will be repeated throughout the manual. The owner/operator/dealer

should know these Safety Messages before assembly and be aware of the hazards of operating this blade

during assembly, use, and maintenance. The Safety Alert Symbol combined with a Signal Word, as seen

below, is intended to warn the owner/operator of impending hazards and the degree of possible injury faced

when operating this machine.

Cutter 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.

INTRODUCTION

SE4 05/05 Introduction Section 2-3

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).
