(SG-9)

Bengal Boom Safety Section 1-3

PELIGRO!

SAFETY
DANGER!

Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death.
(SG-10)

DANGER!

Never allow children to operate or ride on the Tractor or Implement.
(SG-11)

WARNING!

Do not mount the Tractor while the tractor is moving. Mount the
Tractor only when the Tractor and all moving parts are completely
stopped.
(SG12)

DANGER!

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)

WARNING!

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:
1. 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.

2. 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.

3. 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)
Bengal Boom Safety Section 1-5

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 this type
of items discontinue mowing.
(SGM-1)

DANGER!

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)

DANGER!

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)

Bengal Boom Safety Section 1-7

SAFETY
DANGER!

WARNING!

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)
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)
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)
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)

WARNING!
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)

DANGER!

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)
Bengal Boom Safety Section 1-8

SAFETY
WARNING!
Do not mow with two machines in the same area except with Cab tractors
with the windows closed. (SGM-11)

DANGER!

Rotary and Flail Mowers are capable under adverse conditions of
(100 yards or more) and
throwing objects for great distances
causing serious injury or death. Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:
-Front and Rear Deflectors are installed and in good,
working condition;
-Mower Head is 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. (SBM-1)

DANGER!

Use extreme caution when raising the Mower head. Stop the Blades
from turning when the Mower Head is raised and passersby are within
100 yards. Raising the Mower head 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.
(SBM-2)

DANGER!

Be particularly careful in transport. The Mower has raised the center
of gravity for the tractor and has increased the possibility of overturn. Turn
curves or go up slopes only at low speed and using a gradual turning
angle. Slow down on rough or uneven surfaces. (SBM-3)

WARNING!

Never Leave the mower unattended while the head is in the
raised position. The mower could fall causing serious injury
to anyone who might inadvertently be under the mower.
(SBM-4)

WARNING!

The rotating parts of this machine continue to rotate even after the Tractor
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. (SBM-5)
“Wait a minute...Save a life!”
Bengal Boom Safety Section 1-9

SAFETY
Relieve hydraulic pressure prior to doing any maintenance or repair
work on the Implement. Place the Mower Head on the ground or
securely supported on blocks or stands, disengage the PTO, and turn
off the engine. Push and pull the control Levers or Joystick several
times to relieve pressure prior to starting any maintenance or repair
work.
(SBM-6)

DANGER!

Always keep a careful lookout and use extreme care when working
around overhead obstructions. Never allow the Mower head or boom
within 10 feet of any power line. When working close to overhead power
lines consult your electric company for a safe code of operation.
(SBM-7)

DANGER!

When transporting Boom Mower on a truck or trailer, the height or width
may exceed legal limits when the boom is in the transport position.
Contact with side or overhead structures or power lines can cause
property damage or serious injury or death. If necessary lower boom to
reduce height and/or remove mowing head to reduce width to the legal
limits. (SBM-8)

DANGER!

Never operate the Tractor and Mower Unit without an OPS (Operators
Protective Structure) or Cab to prevent injury from objects thrown from
ground or from overhead trimming. Stop mowing if workers or passersby
are with in 100 yards. (SBM-9)

DANGER!

Each Rear Wheel must have a minimum of 1500 pound contact with
the surface to prevent lateral instability and possible tip-over which
could result in serious bodily injury or even death. Widen the wheel
tread and add weights if needed. Refer to the mounting instructions
or call Customer Service if you need assistance with Couterweight
Procedure. (SBM-11)

DANGER!

Always disconnect the wire leads from the mower pump solenoid
before performing service on the Tractor or Mower. Use caution when
working on the Tractor or Mower. Tractor engine must be stopped
before working on Mower or Tractor. The Mower Blades could
inadvertently be turned on without warning and cause immediate
dismemberment, injury or death. (SBM-12a)

DANGER!

The flail cutter shaft is designed for standard rotation (same
rotation as the tractor wheels during forward travel). Never operate the
cutter shaft in the reverse rotation. Operating this mower in reverse
rotation may cause objects to be thrown out the front of the mower
head.

FINAL PREPARATION FOR OPERATION
Place operators safety and operation decals on the steering column and side counsel
where they are clearly visible to the operator. These decals should be understood by
each operator of the machine in conjunction with the safety and operation section of this
book. The decals are to be maintaned in good condition as a reminder to the operator,
and should be replaced if damaged.
Finally, all bosses, pins and pivot points will need to be greased as instructed in the
maintenance section of this manual. The hydraulic reservoir can also be filled with the
recommended fluid (see maintenance section) and the filter installed in the top of the
tank. Double check all fittings and fasteners BEFORE starting tractor. Also secure any
loose hoses together with zip ties and wrap with split hoses where friction may occur on
the hoses.

BEFORE starting or operating the tractor you must read and understand the
safety and operation sections of this manual completely.

BE SURE THE BALL VALVES ARE OPEN! Start tractor and allow instruments to
stabilize. Using a piece of paper or cardboard as noted in the safety and maintenance
sections, check all fittings and connections for hydraulic leaks.
If a leak is found, you must shut down the tractor, set the cutter on the ground.
Before attempting to fix the leak, you must actuate the lift valve handles several times to
relieve any pressure in the lines.
Before operating the mower, the cutter head and boom should be slowly moved
throughout the full range of motion. Watch for any condition that would cause pinching or
excess stress on the hoses. The steering and front axle travel should also be carefully
moved through their full range of motion. If any condition occurs in which the hoses
contact the tires, the steering and / or front axle travel may need to be limited as
described in the tractor operators manual. This should also be done if the tires rub, or
are extremely close to any other part of the mower such as the hydraulic tank or draft
beam. This may include adding shims, or adjusting stop bolts in the tractor front to solve
the problem. While checking motion, you should also check that the control circuits are
connected according to the operators decal for the valve handles.

MOWER TESTING
Take the tractor to a place free of loose objects on the ground. Operate the cylinders
through their full range of motion again, to clear the lines of air. Follow the instructions in
the operation section to operate the mower. Vibration of the mower should be minimal at
all times. After a 5 minute test run, the knife bolts should be retorqued and once again
after the first few hours of operation.

If any parts of this assembly section, or any other section of this manual
are not clearly understood you must contact your dealer or the address on
the front of this manual for assistance!(ASM-C-0010)

Operation Section 3-29

OPERATION

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

OPERATION
Transport only at speeds where you can maintain control of the
equipment. Serious accidents and injuries can result from operating this
equipment at high 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.

OPERATION

Before transporting the Tractor and Implement, determine the proper 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
transport speed not to exceed 20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only after
you determine that the equipment can be operated 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 turning speed for you and this equipment before
operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly control
the equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes
or worn tires. 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)

8.1 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

Boom

Operation Section 3-30

OPERATION
8.2 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. (Ops-0004-MISC)
BEFORE leaving the tractor seat, always set the parking 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)

Boom

Operation Section 3-31

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
8.3 Driving the Tractor and Boom

OPERATION

Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the
tractor. Never operate the tractor 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 and
attached implement handles a turn. Determine the
safe speed to maintain proper control of the tractor
when making turns. When turning with the
implement the overall working length and width of
the unit is increased. Allow additional clearance for
the unit when turning or when passing large
obstructions.

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. Use extreme caution when
operating on steep slopes. Keep the tractor in a low
gear when going downhill. DO NOT coast or freewheel downhill.

THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND
MOWER AND ALL CONTROLS BEFORE ATTEMPTING TO MOW. The operator must read and understand
the Safety and Operation Sections of this manual and the tractor operator’s manuals. These manuals must
be read and explained to any operator who cannot read. Never allow someone to operate the unit without
complete operating instructions.
To ensure safety to the operator, bystanders, and equipment and before starting any mowing operation. The
operator must become familiar with the area to be mowed, and any obstacles and hazards contained within.
Special attention should be paid to foreign debris, overhead obstructions, rough terrain, steep slopes,
passersby and animals in the area.
Only operate the mower head from the tractor operator’s seat with the seatbelt securely fastened. Only
operate a boom and equipped head on cabbed tractor that is equipped with a polycarbonate safety-protected
right side window or a non cabbed tractor equipped with a ROPS and operator safety screen.
Avoid operating in the reverse direction when possible. In situations where the boom and mower must be
backed to access areas to be cut, make sure there are no persons or other foreign debris behind the tractor.
When backing, operate the tractor at a much reduced ground speed to ensure complete control of the unit is
maintained. OPS-B- 0007

Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)

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
300 feet (90 m) 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-01)

Operation Section 3-33

OPERATION

Always keep a careful lookout and use extreme care when working
around overhead obstructions. Never allow the Mower head or boom
within 10 feet of any power line. When working close to overhead
power lines consult your electric company for a safe code of operation.

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.

OPERATION

(SGM-08)

Never operate the mower head tilted down where the operator can see the blades of the
mower. The blade could throw an object toward the operator causing serious injury or
death. Never operate the mower without an Operator Protective Structure. Always wear
safety glasses and a hard hat. (Ops-0005-MISC)

9.1 Foreign Debris Hazards/Overhead Obstructions
An area to be cut must first be inspected for objects that could be thrown or that could damage the machine.
Walk through the area looking for fences, boulders, rocks, culverts, stumps or metal objects. Mark the
inspected area with flags. If the area is dense and cannot be walked thoroughly it may be necessary to inspect
a smaller area as well as possible, then trim away the part that has been inspected and can safely be
removed. Walk each new area again and repeat the inspection before cutting more away. Repeat as often as
necessary until the area is cleared. It can be damaging and/or dangerous to work the cutter in an area that has
not been visually inspected.
Place DANGER signs at least 300 feet beyond the perimeter of the area to be worked, not just 300 feet from
where the machine started operating! It is convenient in many cases to work in 300 foot sections. Move the
first Danger sign to the beginning of the freshly cleared area, place it, then take the first cutting area flag up to
the end of the freshly cleared area 300 feet away. Walk and inspect the next 300 feet and place the second
cutting area flag. Pick up the second DANGER sign, and take it a further 300 feet along the road or trail. Note
that in many cases the DANGER area will extend in front of and behind the machine as well as along each
side. Post signs accordingly. OPS-B- 0008

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-05)

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-06)

Operation Section 3-34

OPERATION
Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). 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-07)

9.2 Operating Speed and Ground Speed

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 implement and most efficient tractor operation. As
the severity of cutting conditions increase, the ground speed should be decreased. OPS-B- 0009

Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). 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-07)

9.3 Operating the Attached Mower Heads
The boom can attach to and operate multiple heads one at a time for a wide range of vegetation control
applications. The attached heads are designed for different applications. The head should be selected based
on the mowing application and the location that the unit is being operated.
Refer to the Assembly Section of this manual to ensure the head is properly attached to the boom hitch and
hydraulic lines are properly connected. OPS-B- 0010
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 300 feet
of mower. (SGM-02)

Boom
©2011 Alamo Group Inc.

Operation Section 3-35

OPERATION

Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Do Not
exceed 5 MPH while operating. 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 operating and desired ground speed. Make sure that the mower is operating at its full
rated speed before entering the vegetation to be cut. Always start and stop cutting blades with engine near
idle.

OPERATION
9.4 Mower Operation
The rotating parts in this machine have been designed and tested for rugged use. However, they could fail
upon impact with heavy solid objects-such as steel guard rails, concrete abutments,etc., causing them to be
thrown at a very high velocity. Never allow cutter head to contact such objects. Inspecting the cutting area for
such objects and removing them prior to mowing can help eliminate these potiential hazards.

OPERATION

Once on location, lower the mower deck slightly above the material to be cut, so the mower does not have to
start under a load. With the tractor at an idle, engage mower. Bring tractor R.P.M. up to 1900-2200 R.P.M. and
slowly lower deck to ground level.
A flail mower deck should be carried so that the part of the deck weight is carried by the boom and part carried
by the ground roller, when moving on the ground. When the flail mower is carried this way, the ground roller
follows the contour of the ground more easily during mowing operations.
The rotary mower deck should always be carried rather than dragged on the skid shoes when mowing on the
ground. Dragging the rotary mower deck increases the side loads on the boom, decreases the horsepower
available to the cutter head, and reduces the ability of the accumulator the carry part of the weight of the boom
during mowing operations.
When rotating parts are in motion, serious injury may occur if caution is not used or danger is
not recognized. Never allow bystanders within 300 feet of the machine when in operation.
Extreme care should be taken when operating near loose objects-such as gravel, rocks, and
debris. These conditions should be avoided.

9.5 50” & 60” Boom Rotary
The 50” & 60” boom rotary brush mower was
designed for cutting brush and foliage up to 6
inches in diameter or multiple branches that have a
total cross section area equivalent to one 6 inch
branch.
During mower operation, the hand throttle must be
used to maintain engine speed at 1900-2200 R.P.M.
This prevents radical changes in mower spindles
speed, reducing the possibility of cutter assembly
damage.
The horizontal positioning action of the boom is
designed to position the cutting head and provide a
limited pressure relief when excessive pressure is
applied to the boom. Do not force the cutting head
into heavy branches or stumps. Damage to the unit may result.
When using the rotary cutting head for trimming trees and shrubs, let the mower saw into them.
Do not lower the mower head down directly into a tree or stump. The mower blades are
designed to cut with the end, and misuse can cause damage to the blade and a hazardous
situation for the operator.
Powering the boom down, forcing mower deck onto ground may damage mower deck and it’s
attachment to the boom, creating a potentially hazardous situation.
To ensure a clean cut, engine speed should be maintained at approximately 1900-2200 R.P.M. If the tractor
slows to less than 1800 R.P.M., shift to the next lower gear. DO NOT ride the clutch, this will cause premature
clutch failure. The engine should not be operated at any time at more than 2400 R.P.M. on the tractor
tachometer.
Boom

Operation Section 3-36

OPERATION
For cutting brush, it is usually best to stop the tractor and swivel the boom and mower into foilage. The
horizontal positioning action of the boom is designed to position the cutting head and provide a limited
pressure relief when excessive pressure is applied to the boom.
DO NOT use excessive force when positioning cutting head into heavy branches or stumps.
Damage to the unit may result. It is best to let the cutter head “eat away” slowly at heavy cutting
jobs.

The mower will operate more efficiently in tougher conditions and with less power if the knives are kept sharp.
If the mower begins to vibrate, stop the tractor, check for wire wrapped in the spindle or damaged knives.
When replacing knives, replace all knives with new knives to ensure proper balance so the mower will not
vibrate. Severe vibration will result, if knives with unequal wear are used.
Begin a pass at the top side of the trees and work down with each consecutive pass. When cutting trees and
shrubs, use a lower speed to allow the knives time to cut as well as mulch the foliage.
If bystanders approach within 300 feet while mower is in operation turn mower switch “OFF”
immediately! After shutdown, never leave the tractor or allow bystanders to approach within 300
FEET of the unit until all motion stops completely.
If cutter shaft jams and stops, turn mower switch to “OFF”, and swivel boom “AFT”. Normally this action will
clear the cutter head. If not, roll mower deck until adjacent to the secondary boom, then lower boom to rest
mower deck on ground. Shut off the tractor, set parking break, allow all motion to cease. At that point it is safe
to leave the tractor and clear the cutter heads manually.
Begin each pass at the top side of the trees and work down with each consecutive pass. Use a low speed to
allow the cutting blades time to mulch as well as cut the foliage. When the initial pass has been made,
disengage the mower, and return boom to a safe travel position. Return to starting point and make next pass,
etc..
After the first day of operation, all bolts should be checked and tightened securely. This should be done
periodically to ensure the bolts do not become loose and cause damage to the tractor or mower, or injury to the
operator.

Boom

Operation Section 3-37

OPERATION

If foliage falls on top of mower deck causing tractor to become unstable, move the boom
“Forward” and “Out” to relieve tipping of the tractor. Lower mower deck to ground and shut
down unit. After all motion stops, remove foliage from mower deck.

OPERATION

OPERATION
When cutting trees and brush approach material
to be cut with the head perpendicular to material.
The cutting edge of the blades should be the
only elements in contact with material. The blade
bar should not contact with material. The mower
head
and
blades
should
be
moved
perpendicularly into the material rather lowering
the mower head on top of material. If the blade
bar edges are gouged or rounded from wear, the
mower head is being used incorrectly in an
abusive manner. The blade bar is not intended to
cut material or to be a wear item like the blades.
Do Not allow the blades or blade bar to contact
the ground, rocks or solid objects. Contact with
the ground can result in rocks and solid objects
being thrown out from under the mower head
which can cause serious injuries to the operator
and bystanders. This type of operation can lead
to bent or broken blade bars, broken blade bolts
and broken blade bar assembly bolts which can
be dangerous to the operator and bystanders.
(OPS-R-220)

9.6 50” Boom Flail
The 50’ boom flail mower was designed for cutting
brush and foliage up to 3 inches in diameter or
multiple branches that have a total cross section
area equivalent to one 3 inch branch. Cutting
multiple limbs at the same time may overload the
mower causing it to slow down or stall completely.
Regardless of the size of material being cut, the
cutter shaft speed must be maintained. To ensure
that the cutter shaft is running at maximum speed,
run the tractor at full throttle during mowing
operations. If the cutter shaft slows to the point that
the knives are folding back, move the mower head
away from the foliage and allow the cutter shaft to
regain full speed.
Operating the mower in a manner that allows the knives to continually fold back or allowing
knive lugs to contact foliage will cause permanent damage to the cutter shaft drum, knives, and
knife attachment parts.
The 50” boom flail cutter shaft is designed for standard rotation (same rotation as the tractor
wheels during forward travel). Never operate the cutter shaft in reverse rotation. Operating
this mower in reverse rotation may cause objects to be thrown out the front of the mower head.
The 50” boom flail equipped with free swinging brush knives is intended for brush cutting only.
Cutting grass is not recommended.

Boom

Operation Section 3-38

OPERATION
Do not allow knives to cut down to the ground. Position ground roller to maintain knife arc at a
minimum of 2 inches above the ground. Knife contact or lug contact with ground will cause
permanent damage to cutter shaft, knives, and knife attachment parts.

9.7 63” Boom Flail

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)

Boom

Operation Section 3-39

OPERATION

The 63” boom flail mower was designed for cutting
grass. The cutter shaft speed must be maintained
for proper cutting. To insure that the cutter shaft is
rotating at maximum speed, run tractor at full
throttle during mowing operations. If cutter shaft
slows to the point that the knives are folding back
against the cutter shaft, move the mower head
away from the foliage and allow the cutter shaft to
regain full speed.

OPERATION
9.8 Shutting Down the Attached Head- For Standard Equipment

OPERATION

To shut down attached mower head, first bring the
tractor to a complete stop. Decrease engine RPM
to idle then disengage cutterhead. The mower head
will come to a complete stop within a suitable
amount of time. Do not engage or disengage the
cutterheads at a high RPM unless there is an
emergency situation.

Park the tractor on a level surface, place the
transmission in park or neutral and apply the
parking brake, shut down the engine, remove the
key, and wait for all motion to come to a complete
stop before exiting the tractor. OPS-B- 0011_D

help ensure years of dependable service. The following are suggested storage procedures:
•

•

•
•

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)
BEFORE leaving the tractor seat, always set the parking 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)

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)

11.TRANSPORTING THE TRACTOR AND IMPLEMENT
Inherent hazards 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

11.2 Transporting on Public Roadways
Extreme caution should be used when transporting the tractor and mower 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 driving, is wider than the tractor tire
width and/or extends beyond your lane of the road. OPS-B- 0014

Boom

OPERATION

Make sure that all tractor flashing warning lights,
headlights, and brake/taillights 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 where 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-B-0015

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
your state or municipality for agricultural tractors.
Always stay alert when transporting the tractor and
mower on public roads. Especially in busy cities,
the boom extends to right farther then the tractors
width, so be careful there are no bystanders, poles,
large obstructions or any vehicles that may be in
path of the mower head or boom. Use caution and
reduce speed if other vehicles or pedestrians are in
the area. OPS-B- 0016

MAINTENANCE
General Instructions
Tiger Mowers are designed for high performance and rugged durability, yet with simplified maintenance. The
purpose of this section of the manual is to help the operator in the regular servicing of the mower. Regular
maintenance at the intervals mentioned will result in the maximum efficency and long life of the Tiger Mower.

MAINTENANCE

When you purchase a Tiger Mower you also acquire another valuable asset, Tiger’s parts organization. Our
rapid and efficent service has guaranteed the customer satisfaction for many years. Tiger parts keep up with
the demands for efficiency, safety and endurance expected of the Tiger Mower.

Maintenance Precautions
•

Be sure end of grease gun and zerks are clean before using. Debris injected into bearings, etc. with grease
will cause immediate damage.

•

DO NOT use a power grease gun to lubricate bearings. These require very small and exact amounts of
lubrication. Refer to the detailed maintenance section for specific lubrication instructions. DO NOT overgrease bearings.

•

Lexan windows should be washed with mild soap or detergent and luke warm water, using a soft clean
sponge or soft cloth. DO NOT use abrasive or alkaline cleaners or metal scrapers on lexan windows!

•

Be alert to maintenance indicators such as the in-tank filter pressure gauge, hydraulic reservoir sight
gauge, etc. Take the required action to correct any problems immediately.

•

Release of energy from pressurized systems may cause inadvertent actuation of cylinders, or sudden
release of compressed springs. Before disconnecting any hoses relieve pressure by shutting tractor off,
setting cutter on ground and actuating lift valve handles.
DO NOT use hands to check for suspected leaks in hydraulic hoses! Hydraulic fluid escaping
under pressure can have sufficent force to penetrate skin and cause serious injury. If fluid is
injected into skin, it must be surgically removed within a few hours or gangrene may result. Use
a small piece of wood or cardboard, not hands, to search for pin hose leaks. Be sure all
connections are tight and hoses and lines are not damaged before applying pressure.

Break in Period
In addition to following the break in instructions for your particular tractor, the in-tank hydraulic fluid filter should
be replaced after the first 50 hours of service. Thereafter the filter should be replaced every 500 hours, or
yearly, which ever comes first.
Re-torque wheel lugs after first five hours of operation and periodically thereafter. See torque specifications
listed in the tractor’s service manual for your particular model. Wheel lugs must always be re-torqued
whenever a wheel is removed and reinstalled.
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)

Boom

Maintenance Section 4-2

MAINTENANCE
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)

Always disconnect the wire leads from the mower pump solenoid
before performing service on the Tractor or Mower. Use caution when
working on the Tractor or Mower. Tractor engine must be stopped
before working on Mower or Tractor. The Mower Blades could inadvertently be turned on
without warning and cause immediate dismemberment, injury or death. (SBM-12a)

POLYCARBONATE CARE & MAINTENANCE
The proprietry UV and Abrasion Resistant Surface coating on SHIELDS SUPERCOATED polycarbonate
significantly improves performance. Periodic cleaning using proper procedures and compatible cleaners are
recommended to prolong service life. Tiger Corp. polycarbonate is SUPERCOATED on both sides.

MAINTENANCE

CLEANING THE SUPERCOAT HARD-COAT
1.

Wash with a mild solution of soap or detergent and lukewarm water.

Using a soft cloth or sponge, gently wash the sheet to loosen dirt and grime and rinse well with clean
water.

To prevent water spotting, thoroughly dry with chamois or cellulose sponge.

Avoid the use of abrasive cleaners, squeegees and/or other cleaning implements that may mar or
gouge the coating.

All residual organic solvents should be removed with a secondary rinse.

GRAFFITI REMOVAL
Butyl cellosolve (for removal of paints, marking pen inks, lipstick, etc.) The use of masking tape, adhesive tape
or lint removal tools work well for lifting off old weathered paints.
To remove labels, stickers, etc., the use of kerosene or VM&P naphtha are generally effective. When the
solvent will not penetrate sticker material, apply heat (hair dryer) to soften the adhesive and promote removal.
IMPORTANT: If a material is found to be incompatible in a short-term test, it will usually be found to be
incompatible in the field. The converse, however, is not always true. Favorable performance is no guarantee
that actual end-use conditions have been duplicated. Therefore, these results should be used as a guide only
and it isrecommended that the user test the products under actual end-use conditions.

RECOMMENDED FILLING INSTRUCTIONS FOR HYDRAULIC
RESERVIORS

If your reservior has two sight glasses: The
reservior should be filled to the top of the lower
sight glass on the side of the tank. Do not over-fill.
The reservoir has been over-filled when oil is visible
in the upper sight glass. If tank has too much oil, the
excess may be expelled through the pressurized
breather.

If your reservior has one sight glass/temperature
gage: The reservior should be filled to the center
of the sight glass on the side of the tank. Do not
over-fill. If the tank has too much oil, the excess
may be expelled through the pressurized breather.

DETAILED MAINTENANCE
REPLACEING IN-TANK HYDRAULIC FILTER:
Loosen the four bolts on the top cover of the filter
housing. Turn cover counter-clockwise until cover is
free. Remove and replace filter. Replace top cover
and cover bolts in opposite order as removed.

MAINTENANCE
DETAILED MAINTENANCE

MAINTENANCE

REPLACEING HIGH PRESSURE HYDRAULIC
FILTER ELEMENT:
Assure system has been shut down and depressurized. Locate High Pressure Filter housing.
Confirm that the element that is about to be
installed matches the element p/n on the filter
model tag. Example: V3.0510-06 (world line 100,
HD049 model) Locate the bottom of the High
Pressure Bowl, and use the appropiate spanner
wrench-or-ratchet and turning in a counterclockwise
rotation, (looking at the bottom of the bowl) remove
the bowl from the head, The first couple rotations
will seem tight as the o-ring passes the sealing flats.
Once the o-ring has cleared the sealing flats the
bowl should spin freely. Taking care not to drop the bowl, finish removing the bowl from the head. WARNING:
bowl will be full of oil! Pour the oil from the bowl into a container, this oil should be considered contaminated
due to the flow direction through the element is outside-in. Clean the inside of the bowl if “dirt” is present.
Remove the old element from the filter head by pulling with a rotation motion. Dispose of the used element
properly. Remove the new element from the packaging. Using your finger, dab and lubricate the o-ring in the
top of the new element. Install the new element into and on the mounting boss within the head; assure that
the element is fully seated on the boss. Clean and inspect the o-ring that is affixed in the bowl, lubricate with
oil. Using a clockwise rotation, screw the bowl back into the head, assuring that the bowl has not been cross
threaded into the head. Continue “tighten” the bowl into the head, using the spanner wrench-or-ratchet, the
rotation of the bowl will become tighter once the o-ring engages the sealing flats. Once the bowl has bottomed
out, “back-off” the bowl by 1/6 turn, this assures that the o-ring is seated properly with in the sealing flats.
Element change out and re-assembly is now complete. Start the machine and inspect the filter area checking
that there is no oil leaking from the filter assembly. This is first to be done at 50 hours of operation, then yearly
(500 hours) or when indicated by restriction indicator.

replace the blade bolts, nuts, and washers.

MAINTENANCE

Make sure the mower blades are turning clockwise when looking
down from the top of the mower. Follow the color coding on the
hydraulic hoses and fittings to make sure the motor and hydaulics
hoses are assembled properly. Connect the red hose connection only
to red fitting. Connect the blue hose connection only to the blue
fitting. The blade rotation on the leading edge of the mower should
discharge the cut material away from the tractor and operator.
If the leading edge of the mower blades are rotating backwards they
can discharge material toward the operator. If this occurs discontinue
mowing immediately and revers the direction of the motor rotation by
correctly installing the motor pressure and return hoses. Contact
your dealer or Alamo Industrial for specific information on the hose
routing.

BEARING INSTALLATION
1.

Press upper bearing cup into the spindle
housing.

Turn the spindle housing over and press in
the lower bearing cup.

Place the lower bearing cone in the bearing
cup. Next press the seal into the spindle
housing. The inner lip of the seal must be
DOWN, towards the bearing, so lubricant is
sealed inside the housing.

Install the spindle in the housing. Lightly
press the spindle to seat the cone onto the
spindle.

Support the bottom of the spindle and press
the upper bearing cone and bearing adjustment sleeve onto the spindle.

NOTE: The spindle housing must turn freely when seating the bearing cone and sleeve.

Press the two upper seals into the spindle housing. The inner lip of the seals must be UP, away from
the bearing, so excess lubricant can escape.

Install the bearing adjustment nut (thin nut) so there is 1-1/6” clearance between the nut and the
sleeve. Install the jam washer, placing the tab into the key-way. Install the bearing lock nut (thin nut)
and hand tighten against jam washer and adjustment nut. See the following section for bearing
adjustment.

Position the spindle housing horizontally with the drain hole oriented “up”. Grease through the zerk
with Tiger Spindle Lubricant (part number 06540000) until the grease purges from the drain hole.

10.

Install the plug into the drain hole.

BEARING ADJUSTMENT
1.

Clamp the bottom end of the spindle
securely in a vise so the spindle housing
turns freely.

Position a magnetic base dial indicator on
the outer diameter of the spindle housing.
Locate the end of the dial indicator against
the flat end of the spindle shaft. The dial
indicator will now measure accurately
bearing end play.

Tighten the bearing adjustment nut until
there is .012 inch movement when the
spindle housing is pried upward away from
the vise jaws.

When there is .012 inch free play between
the spindle and housing, install the bearing lock nut (thick nut). Hold the adjusting nut securely and
tighten the lock nut to 300 ft. lbs. of torque.

After the lock nut is tightened, there must be .001 inch to .003 inch of free play when lightly prying up
on the spindle housing.

If the end play is correct, .001 inch to .003 inch, bend tabs up on jam washer to prevent the lock nut from
loosening.
If the end play is NOT correct, loosen the lock nut and turn the adjustment nut as required and re-tighten the
lock nut. Repeat first part of step 5.

Allow the system to cool to room temperature before removing any hydraulic components
Wear Safety glasses and impenetrable gloves when working with hydraulic hoses and fittings.
Release all oil pressure from the hydraulic circuit by manually stroking each valve section with the tractor engine off. Utilize the Manual Override function if the unit is equipped with an electric over hydraulic
valve.
Utilize blocks, jack stands or a suitable over head hoist to support the weight of the boom section and
remove pressure form the cylinder mounting pins.
Check to see that the cylinder to be replaced is not under pressure by moving the cylinder pins by
hand. The pins should be loose and should slide form the pin bore easily. If the pins are tight and cannot be moved, the cylinder may be under pressure. Make sure the boom components are properly supported and that the pressure is relived from the circuit.
Cylinder assemblies are heavy and can fall when the pins are removed. Support the hydraulic cylinder
with a suitable hoist or jack.
Slowly loosen the hydraulic connections to the cylinder. Carefully unscrew hose fitting and allow any
remaining pressure to bleed off. Use Extreme Care. Oil must be cool, and the technician should stand
to the side to prevent exposure to any hydraulic oil. Always consult the Material Safety Data Sheet and
wear any required Personal Protective Equipment. A catch pan may be required to retain any spilled
oil.
Cap both ends of the fitting with suitably sized metal caps.
Remove the cylinder pins starting with the ROD end cylinder pin. Make sure the cylinder is properly
supported, and remove the base end cylinder pin. The cylinder may be heavy, use proper lifting techniques to lift and handle the cylinder. If needed, get assistance from another person to safely lift the cylinder from the machine.
Measure the distance between the cylinder pin holes and extend the new cylinder the correct length
prior to attempting an installation.
Install the new cylinder in place and install both cylinder pins and retaining hardware.
Remove the metal caps, and re-install the hydraulic hoses.
Check the hydraulic reservoir of the boom mower to ensure there is sufficient oil. Follow the manufactures recommendations for proper oil type and filtering techniques and requirements to add oil to the
system.
Clear the area of all persons prior to starting the tractor.
Consult the Operator's Manual for instruction in regard to the proper operating procedure.
From the tractor seat, with the seat belt fastened, operate the boom to ensure proper operation of the
boom function.
From the tractor seat, with the seat belt fastened, operate the boom controls to fully extend and retract
the new cylinder several times to purge any trapped air from the system.
From the tractor seat, with the seat belt fastened, look for signs of and oil leak. If an oil leak is
observed, shut the tractor down and follow the steps to remove pressure from the hydraulic circuit.
Identify the source of the leak, and resolve the issue.
Upon completion of the required repairs, return to Step # 16 to recheck the cylinder for proper operation.

MAINTENANCE

CUTTERSHAFT BEARING REPLACEMENT
1.

Remove existing cuttershaft, bearings and string guards.

Make sure that the end knives on each end of the cuttershaft are orientated as shown.

Apply anti-seize on cuttershaft as shown on next page.

Install non-drive side bearing first.

Install the top of the string guard on the non-drive side first. Use loctite-271 or equvalent and
torque (95 ft-lb or 104ft-lb if you use an extension).

Install the bearing and top string guard on the drive side.

Center the cuttershaft between the string guards. Use loctite-271 or equivalent and torque
(95ft-lb or 104ft-lb if you use an extension) the top string guard on the drive side.

Install, use loctite-271 or equivalent, and torque (95ft-lb or 104ft-lb if you use an extension)
the bottom string guard on both sides.

Make sure the cuttershaft is centered. On the non-drive side, tighten one set-screw in the bearing onto
the cuttershaft.

10.

Remove the other set-screw and drill a 5/16” hole into the cuttershaft 3/16” deep through the hole in
the bearing. BE CAREFULL NOT TO DAMAGE THE THREADS IN THE BEARING HOLE.

11.

Replace the set-screw in the bearing, use loctite-271 or equivalent, and tighten onto the cuttershaft
through the new hole.

12.

Remove the other set-screw and repeat the drilling procedure (Step 10). Replace the set screw as
stated in Step 11.

13.
