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 Rhino 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.

General Safety Instructions and Practices
SAFETY
A 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
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.
Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR
VERY SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH
OR SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR
INJURY.
Identifies special instructions or procedures that, if not strictly observed, could result in
damage to, or destruction of the machine, attachments or the environment.
NOTE: Identifies points of particular interest for more efficient and convenient operation or repair.(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)
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 to
operate the Tractor or 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 that may be thrown by
the equipment. (SG-16)
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 manufacturer’s
instructions when handling oil, solvents, cleansers, and any other
chemical agent. (SG-22)

SAFETY
Operator Safety Instructions and Practices
SAFETY
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)
SAFETY
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)
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
ground 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)
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)

Safety Section 1-4
SAFETY
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!”
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up. (SFL-2)
Do not put hands or feet near the cutter bar. Blade contact can result
in serious injury. Stay away until all motion has stopped and the
mower is securely blocked up. (SSM-1)
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-03)
Connecting & Disconnecting Implement Safety Instructions & Practices
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 Counterweight Procedure. (SBM-11)
Do Not attempt to raise or lower the boom or mower head unless the Implement is securely
attached to the Tractor. The Implement could tip over and cause equipment damage and
possible serious injury or death. Do Not use the boom controls to assist in installing the
implement on the tractor. Raise or Lower the boom and mower head only while seated in
the Tractor operator’s seat with the seat belt securely fastened. Inadvertent contact with
the boom controls could allow a component to fall. A sudden or inadvertent fall by any of
these components could cause serious injury or even death. (SBM-23)

SAFETY
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up. (SGM-09)
SAFETY
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 A-Frame. Lower the implement carefully to the ground. Do not put hands
or feet under lifted components. (S3PT-1)
SAFETY
This Implement may be 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)
Use extreme caution when raising the Mower head. Stop the Blades from turning when the
Mower Head is raised and passersby are within 300 feet. 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)
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)
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)
The center of Gravity of Tractors equipped with a Rear-Mounted Boom
Mower is shifted to the rear and removes weight from the front wheels.
Add front ballast until at least 20% of the tractors weight is on the front
wheels to prevent rearing up, loss of steering control, and possibly
injury. (SBM-10)
The Mower shaft speed must not - UNDER ANY CIRCUMSTANCES - exceed 1800 RPM.
(SBM-15)
Use extreme care and Safety Awareness when using the boom mower head to mulch loose
brush or wood that has fallen on the ground from overhead trimming. DO NOT mulch this
debris if bystanders, vehicles, livestock or buildings are within 300 feet of the mower. This
cut debris can be thrown at great velocities and could result in serious injury or even death. (SBM-17)

Safety Section 1-6
SAFETY
Do not back up this implement when the boom or mower head is extended. Backing could
damage the machine or its components. (SBM-19)
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 accessible
location.
-Do Not smoke or have an open flame near the Mower and
Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Do Not attempt to mow or place the mower head close to
burning debris.
-Never allow clippings or debris to collect near drivelines,
gearboxes or hydrualic componts such as valves, tanks,
pumps and motors. Periodically shut down the Tractor and
Mower and clean clippings and collected debris from the
mower deck. (SBM-20)
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)

Safety Section 1-7
SAFETY
-Do Not operate the Mower on a Tractor with an underframe
exhaust.
SAFETY
Flail Mowers are capable under adverse conditions of throwing
objects for great distances (300 feet or more) and causing serious
injury or death. Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 300 FEET UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable
condition;
SAFETY
-Mower sections
exposed Blades;
or Wings are running close to and parallel to the ground without
-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.) (SFL-6)
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 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)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
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
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily. (SG-11)

Safety Section 1-8
SAFETY
Do not mount or dismount 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)
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)
In case of mechanical 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 stopped before dismounting. (SG-39)
2160 02/10

Safety Section 1-9
SAFETY
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil
and fuel are explosive 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 unit 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)
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 moving
tractor. (SG-40)
SAFETY
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-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 300 feet
of mower. (SGM-02)
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-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)

Safety Section 1-10
SAFETY
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)
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.
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)
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 nonvegetative 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)
Never leave the Implement and Power Unit unattended while the Implement is in the raised
position. Accidental operation of a lifting lever or a hydraulic failure may cause the
implement to suddenly fall causing serious injury or possible death to anyone who might
inadvertently be under the Implement. Lower the implement carefully to the ground. Do not
put hands or feet under lifted components. (SPU-3)

SAFETY
(SGM-08)
SAFETY
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-07)
Maintenance and Service Safety Instructions and Practices
SAFETY
Make sure the PTO shield, integral driveline shields, and input shields
are installed when using PTO-driven equipment. Always replace any
shield if it is damaged or missing. (S3PT-8)
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)
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)
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)
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. (SBM-18)

SAFETY
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)
SAFETY
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)
SAFETY
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)
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR
OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY
CAUSE SERIOUS INJURY FROM THROWN BLADES. (SGM-10)
DO NOT weld or repair rotating mower components. Welds and other repairs may cause
severe vibration and/or component failure resulting in part being thrown from the mower
causing serious bodily injury. See your Authorized Dealer for proper repairs. (SGM-13)
PARTS INFORMATION
Rhino mowers use balanced and matched system components for blade carriers, blades, cuttershafts, knives,
knife hangers, rollers, drivetrain components, and bearings. These parts are made and tested to Rhino specifications. Non-genuine "will fit" parts do not consistently meet these specifications. The use of “will fit” parts
may reduce mower performance, void warranties, and present a safety hazard. Use genuine Rhino mower
parts for economy and safety. (SPRM-1)
SEE YOUR RHINO DEALER
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 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-02)
2160 02/10

Safety Section 1-14
SAFETY
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)
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)
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 within 300 feet. (SBM-9)
The Joystick Master Control Switch must be OFF to prevent accidental movement of the
boom and cutting head whenever the mower is not being operated. (SBM-16)
Secure the boom and mower head in the transport position before traveling on public roads.
Never transport on public roads with the boom and mower head extended. Always
disengage and lock out the hydraulic controls for the boom mower before transporting.
Inadvertent boom movement on public roads may contact with other vehicles resulting in
serious bodily injuries or even death. (SBM-21)
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)
2160 02/10
© 2010 Alamo Group Inc.
Safety Section 1-15
SAFETY
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)
SAFETY
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.
SAFETY
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)
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)
Concluding Safety Instructions and Practices
In addition to the design and configuration of this Implement, including Safety Signs and Safety Equipment,
hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper
training of personnel involved in the operation, transport, maintenance, and storage of the machine. Refer
also to Safety Messages and operation instruction in each of the appropriate sections of the Tractor and
Equipment Manuals. Pay close attention to the Safety Signs affixed to the Tractor and Equipment. (SG-18)

INTRODUCTION
The 2160 is ideal for mowing pond embankment levee or drainage ditches, and cutting overhanging limbs on
fence rows.
For Non-Agricultural use, OSHA, ASAE, SAE, and ANSI standards require the use of Chain
Guards, Deflectors, or Solid Skirts at all times. The Mower manufacturer strongly
recommends the use of Chain Guards or Rubber Deflectors 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 Mower lifted to provide
adequate traction for safe steering under good conditions. Slow down on hills, rough terrain,
and curves.

DRIVELINE LENGTH CHECK PROCEDURE
Before using mower check driveline length with tractor attached to mower.
1. Separate two halves of driveline and connect one half to tractor and the other half to mower.
2. Lower mower to normal operating position.
ASSEMBLY
3. Bring the two driveline halves together as shown in figure 6. At this maximum compressed length there
should be 1-1/2 inches or more clearance from tubes bottoming out. If not, shorten the driveline to obtain
clearance. Shorten shield tubes and sliding profiles by the same amount. Round off all sharp edges and
remove burrs. Grease the sliding profiles.
4. Raise mower to transport position. Check driveline length at this maximum extension to make sure profile
tubes are always engaged at least 8 inches.
When attaching PTO yoke to tractor PTO shaft, it is important that spring activated locking
collar slides freely and is seated in groove in PTO shaft.
Be sure PTO shielding and all other shielding is installed and is in good condition.

HOSE CONNECTION
When assembling the fittings and hoses, be careful not to introduce any dust or contaminants into the system.
Keep all fittings, hoses and hydraulic components sealed until installed. Do not allow any components to lie
open and exposed to dust or contamination. Do not lay parts down on the dirt or sand and then assemble them
as this will introduce contaminants into the system.
To avoid Hydraulic Contamination, always keep all hoses and hydraulic fittings capped until they are ready to
be installed. Asm-B-0006.

ATTACHMENT OF HYDRAULIC HOSES
It is important that pipe thread sealant be used only on pipe threads; never on 37 degree flared fitting or on
straight thread “O” ring fittings. Use the pipe thread sealant supplied. Do not substitute with some other type of
sealant, such as, teflon tape, paint, shellac, etc.
Hoses supplied have two types of fittings; solid or swivel. Some hoses have solid fittings on both ends; others
have a solid fitting and a swivel fitting. Hoses with two solid fittings will fit into either an internal solid thread or a
swivel adapter union. When installing either type hose, solid fittings must be installed first, then install the
swivel end of the hose or fitting.
The hydraulic system incorporates three basic types of hydraulic fittings:
a. Standard pipe (NPT or NPTF) thread fittings. This type requires a small amount of evenly-applied sealant.
b. Swivel fittings. This type does not require any sealant on swivel end because it seals against an internal
flare.
c. “O” ring fittings. This type does not require any sealant on the “O” ring end of the fitting.
It is extremely important to avoid getting pipe thread sealant inside the fitting or hoses. KEEP THE INTERIOR
OF ALL HYDRAULIC COMPONENTS CLEAN. Inspect the inside diameter of each hose before assembly.
Make certain that no obstruction is present. Dirt, sand, dust, etc. are abrasive and once in the system can
cause immediate or early failure.
HOSE CONNECTIONS ELECTRONIC
A break-away valve for the swing cylinder must be
mounted to the top of a valve mount plate on the
Main Frame (7) with 2 - 1/4" x 2 3/4" bolts (1) and
fastened with 1/4" locknuts (2). Attach the 90°
elbows (4) to the "A", "B", "C1", and "C2" ports of
the breakaway valve. Attach the straight adapter
(6) to the "T" port of the breakaway valve. A relief
hose is then connected to the other 90 degree
elbow (5) which is connected to a straight adapter
(6). The other end of this hose is connected to a
filler tube on the tractor hydraulic tank by a special
adapter.
NOTE: When connecting the hose from the
breakaway valve to the tractor hydraulic filler tube,
there are two types of adapter depending on the

MOUNTING THE REMOTE COMMAND HANDLE
The control handle is normally mounted to an existing tractor remote lever. The control handle selects one
cylinder on the boom to be operated from a remote outlet.
The metal bracket at the base of the control handle is mounted to the remote lever using the U-bolts and
hardware included. Choose either the round U-bolts for round shafts or the flat U-bolts for flat shafts. Two allen
head screws in the mounting bracket are used to keep the handle from rotating on a round shaft and can also
be used to hold the bracket more securely on a flat shaft.
The bracket at the base of the handle can be reversed if needed by removing the allen head screws.
Pull the bracket out of the bottom of the handle, turn it around and replace it in the handle. This allows you to
place the handle in the front of or behind the remote lever providing additional clearance for other controls.
The bracket may be bent, tilting the handle to one side or the other to provide clearance for other controls or to
make the control more comfortable to operate. To reduce the possibility of damaging the handle, the bracket
should be removed from the handle before bending.
After mounting the handle, route the cable away from the handle leaving enough slack in the line to provide
free movement of the control. Secure the cable with the cable ties included.
Unless otherwise specified, all control systems are designed for use on 12 volt, negative ground electrical
systems only. The red and black power wires are to be connected as follows:
Connect the black wire to the frame of the vehicle or to the grounded terminal of the battery.
Connect the red power wire to the source of power, normally this connection is made at the fuse panel. You
must fuse the power wire using the fuse and holder supplied, locate the fuse as close to the source of power as
possible. The power should be controlled by the ignition key to prevent the battery from being drained when
the engine is not running.
Apply decal provided to interior of cab window or other convenient surface.
After the Handle is properly installed the Wiring Harness can be connected to the Valve Harness by connecting
the 9 pin sockets.
Wire harness from valve must run through outside window as shown.

OPERATION
3.4 Tractor Ballast
For additional information on properly ballasting the tractor, refer to Alamo Industrial Tractor and Mower
Stability Pamphlet P/N #02959010
If the unit is operated on slopes greater than 5°,
additional counterweight will be required.
Operation of the unit on slopes greater than 11
percent (6.4 degrees) is not recommended under
any circumstances. On a tractor with a 96” outside
to outside tire spread, an 11 percent (6.4 degrees)
slope occurs when one rear tractor tire is about 8”
lower than the other rear tire. OPS-B- 0018
Do not operate the unit under any circumstance if the slope is 10 degrees or greater.
3.5 Tractor Safety Devices
If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with
proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of
the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor
warning signals are obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were

with the PTO master shield missing or in the raised position. OPS-U- 0004
2160 02/10
© 2010 Alamo Group Inc.
Operation Section 4-7
OPERATION
To ensure tractor stability when operating on flat surfaces the left rear tractor tire MUST exert a minimum
down force (weight) of 1500 lbs. on the ground when the tractor is on level ground, its boom is fully extended
and the mower head is horizontal and two feet above the ground. For units which have the ability to operate
on either side of the tractor, these requirements must also be met for the right side tire when the boom is
extended to the left side as described above. A tractor that does not meet this criteria is DANGEROUS and
should not be operated as upset of the unit can occur resulting in possible serious injury and property
damage. NOTE: All factory mounted units are tested and meet the ballast requirement before shipment;
further testing is not required unless the unit is operated in a manner other than what is considered standard
operating conditions.
OPERATION
3.6 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
OPERATION
3.7 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 or a 1-3/4” 20 spline shaft. Refer to the tractor owner’s manual for instructions to change PTO speeds on
models that operate at more than one speed.
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
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 Implement resulting in
excessive vibration, thrown objects, and blade and implement 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)
4. 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 or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped. (SG-12)

4.1 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.
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
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily. (SG-11)
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped. (SG-12)
4.2 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

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
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)
7. 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)

according to maintenance schedule.
• Ensure there are no oil leaks and fitting are
properly connected
• Inspect overall condition of hydraulic pump.
• Inspect pump drive shaft.
Check the fluid level in the Hydraulic Tank on the Tractor, and add oil if required. As the air has been forced out
of the Cylinders and Hoses, it goes into the Hydraulic Tank and reduces the volume of oil. Maintain the oil level
within the sight gauge located on the side of the resevoir. Never fill the tank above the sight gauge to allow for
the expansion of the oil. The tank maintains pressure after the mower has been run. Stand off to one side
when removing the breather cap element to prevent possible injury. To relieve pressure remove the breather
cap element and depress the spring loaded pressure valve to release any excess air. OPS-B- 0024_H
Attention: Oil Filter Cap is also the Pressure Relief Cap. Remove cap slowly to relieve
pressure before removing cap completely. Stay clear to prevent scalded with hot oil that may
spray out of the tank that is pressurized and may cause serious injury to eyes, face and
exposed skin.
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

8. DRIVING THE TRACTOR AND IMPLEMENT
Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and
precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the
weight of the implement and the tractor operating controls are set for safe transport. To ensure safety while
driving the tractor with an attached implement, review the following. OPS-U- 0012
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
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)

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
8.1 Starting the Tractor
OPERATION
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
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)
8.2 Brake and Differential Lock Setting
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.
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. OPSU- 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.

8.3 Driving the Tractor and Boom
Inspect the area to be mowed before beginning operation. Identify any drop-offs, slopes, holes, hidden
obstructions or similar obstacle that could cause the tractor to loose stability and potential roll-over. Mark and
avoid the item or the entire area.
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.
DO NOT BACKUP WITH HEAD IN MOWING
POSITION.
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
free-wheel downhill.
OPS-B- 0006_F
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)

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.
OPERATION
9. OPERATING THE TRACTOR AND IMPLEMENT
OPERATION
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
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-1)
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 were
safety glasses and a hard hat.
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
2160 02/10

Operation Section 4-26
OPERATION
Use extreme care and Safety Awareness when using the boom mower head to mulch loose
brush or wood that has fallen on the ground from overhead trimming. DO NOT mulch this
debris if bystanders, vehicles, livestock or buildings are within 300 feet of the mower. This
cut debris can be thrown at great velocities and could result in serious injury or even death. (SBM-17)
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)
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)
9.2 Operating the Control Valves
The 2160 has two control valves. One is the on-off switch to the cutter motor and the other is the position
control valve.
ON-OFF Switch (Mower Valve) - To operate the mower, pull the switch while the tractor is running. The pushpull operator will remain in the ON position PULLED or the OFF position PUSHED until the operator desires to
start or stop the mower. Always start the cutterhead with the tractor at idle.
The operator should not leave his seat with this valve engaged or with the tractor engine
running. Allow approximately 60 seconds for the blades to come to rest after turning the
switch off before dismounting.
2160 02/10
© 2010 Alamo Group Inc.
Operation Section 4-27
OPERATION
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)
OPERATION
OPERATION
The mower valve comes with a push-pull operator switch that, when properly installed, will prevent the tractor
from starting if the switch is in the ON position (pulled out). To properly install the push-pull operator, follow the
wiring diagram shown. Failure to properly install this switch could result in injury to the operator or bystander.
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)
Become familiar with the Arm Movements by actuating the cylinder one at a time. For the electro hydraulic
option Select and Depress the Button on the handle corresponding to the correct cylinder. Slowly actuate the
Remote hydraulic Handle of the Tractor and observe proper operation of the Boom. To Select another cylinder
return the Remote Handle to the Neutral position, select and depress a different Button and then actuate the
Remote Handle once again. Before attempting to operate this equipment, read these instructions completely. If
you have any questions concerning safety of operation, contact your dealer or Rhino.

OPERATION
With the exception of the relief valves, which are preset at the factory, these are all the controls for operating
the machine other than the controls on the tractor itself.
OPERATION
9.3 Operating Speed and Ground Speed
OPERATION
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Do Not
exceed 2 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.
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 by selecting a lower gear to
maintain the proper operating PTO speed. 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)
9.4 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,

Rotary Cutter
•
•
•
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)
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)

OPERATION
•
The Rhino 2160 Rotary Cutting Head is rated
to cut vegetation up to 2” in diameter.
Objects tend to be thrown out from under the
head in the direction of blade rotation and
toward the raised edge of the shroud. Avoid
cutting with the head tilted at an angle that
objects would be thrown towards the tractor
operator position.
When clearing brush and small trees, operate
tractor at 1 mph ground speed and position
cutter head at an angle that will cut 2’ to 3’ into
the growth. Make the first pass just above
ground level. This will remove the low
branches and allow operator a better view of
the material to plan fro the next pass. After
repeated passes, each elevated approximately
4’ above the last, the main trunks of the trees
will be exposed and they can be cut as
desired. This avoids clogging the head with cut
and mulched material.
When operating near the ground or when
mulching, be particularly careful that there are
not bystanders or animals within a 100 yards.
Debris tend to fly out at great speed and can
injure or even cause death. OPS-B- 0061

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

OPERATION
11.1 Transporting on Public Roadways
OPERATION
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
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
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)
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 transporting Boom Mower on a truck or trailer, the height or width
may exceed legal limits when the boom is in the transport position.

Before transporting a loaded tractor and implement,
measure the height and width dimensions and gross
weight of the complete loaded unit. Ensure that the
load will be in compliance with the legal limits set for
the areas that will be traveled through. OPS-U- 0024
Use adequately sized and rated trailers and
equipment to transport the tractor and implement.
Consult an authorized dealer to determine the proper
equipment required. Using adequately sized chains,
heavy duty straps, cables and/or binders, securely tie
down both the front and rear of the tractor utilizing the
proper tie down locations as specified by the tractor
manufacturer. OPS-U- 0025

Operation Section 4-38
OPERATION
Arrange the chains so that when tightened, the
chains are pulling downward and against
themselves. Carefully tighten the securing chains or
other fasteners using boomers or binders to apply
maximum tension.
Use extreme care when
attaching and removing the securing devices as the
extreme tension involved when released has the
potential to inflict serious injury.
12. TROUBLESHOOTING GUIDE
A. HYDRAULIC CYLINDER NOT WORKING - Check level of hydraulic fluid (see sight gauge on tank). Check
to see if pump is functioning properly by attempting to use another cylinder or pressure gauge. If pump is
working properly, check the pressure on the line. The relief valve may be by-passing fluid at too low
pressure. If cylinder is still not functioning properly, check the line for stoppage. The pistons in hydraulic
cylinders are virtually trouble-free, but occasionally one will have a scored wall and allow oil to flow around
the piston. In this case, replace the cylinder.
NOTE: Refer to repair parts section on valve bank settings on individual relief cartridges.
B. HYDRAULIC MOTOR NOT WORKING - Check lines for kinks or pinched place. If motor is “bogging down”
under load, recheck the relief valve setting on the cutter valve - 2500 PSI.
C. HYDRAULIC VALVE - Failures in the hydraulic system are almost always caused by other elements in the
system other than the valve; so the entire system should be checked before valve is changed. A
malfunction in any hydraulic valve section will require replacement of that section (but not the replacement
of the valve bank) since the insides are honed to fit individually. Attachment such as the relief valves and
detents may be serviced individually.
D. STRUCTURAL MEMBERS - Failure in structural members generally results from rough treatment. While
they are constructed to withstand abuse, they cannot be made strong enough to withstand abnormal
abuse. The factory does not warrant these parts to any extent other than in normal use in grass, weeds,
brush, small bushes, and small trees which the unit is designed to cut.

BLADES
Check the Blade for cracks and wear and Blade Bolts for tightness, daily. Blades should be replaced when they
are worn excessively, bent, deformed, or out of balance.
Blades should always be replaced in pairs. Blades of different weights can cause serious
imbalance and damage to the machine and personnel. When replacing blades, take care to
replace the bolts, nuts and washers.
Most nuts and bolts will stay tight and therefore need only periodic checking. However, the following nuts and
bolts are extremely important and should receive special attention:
Spindle Housing Bolts:
Tighten to 240 ft./lbs. Torque
Blade Bolts:
Tighten to 300 ft./lbs. Torque
Blade Carrier Hub Bolts:
Tighten to 450 ft./lbs. Torque
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.
When sharpening blades, grind each blade the same amount 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.
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.
When changing Blades always replace the Blade Bolt & Blade Nut at the same time.
Reused Blade Bolts or Nuts could fail in a hazardous manner that could cause injury.
Inspect Blades daily for normal wear. If Blades have a notch worn into the leading worn into
the leading edge at the lower bend more htan 1/2” DEEP (due to running in gravel and/or
the ground), REPLACE BOTH BLADES ON THAT CARRIER IMMEDIATELY. Failure to
replace such abnormally worn blades may lead to catastrophic failure of the blade and
ejection of the broken part with tremendous force which may cause bodily injury or death.
NOTE: Replace Blades in pairs after no more than 1/2” notch wear.

Maintenance Section 5-9
MAINTENANCE
Blade bolt fit into carrier bushings should be checked every time blades are changed. The blade bolt should fit
into carrier bushings as a snug slip fit. If the blade bolt fit appears to be loose or sloppy, measure the square
hole in bushing. If the bottom of the square hole is 1/16” or greater than the square shoulder of the new blade
bolt the bushings should be replaced. Bushings can be removed by cutting bushing head where it is welded to
carrier bar. Once head is removed bushing can be pressed out of bar. Clean and grind top of blade bar so new
bushing can be installed and welded. Bushing should be pressed into bar as far as possible. Use low hydrogen
rod to weld bushing in place.
MAINTENANCE
BLADE CARRIER INSTALLATION
Clean the taper on both the blade carrier and output shaft. Position carrier on the gearbox output shaft and
install special washer nut. Tighten nut, while holding blade carrier, to minimum 450 ft./lbs. 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 450 ft./lbs. Install cotter pin and spread.
MAINTENANCE
Operating the mower with a loose blade pan or holder can damage the taper connection on
the gearbox output shaft. To ensure proper seating between the blade holder and output
shaft, check and tighten the retaining nut after the first day of operation. Recheck the blade
carrier attachment each morning before operating. Grasp the carrier firmly with both hands
and try to push and pull the carrier with one hand while pulling and pushing with the other
hand to try to rock or oscillate the blade carrier. If the carrier is loose, tighten the retaining
nut before operating the mower.
Always recheck spindle output shaft slotted blade carrier retaining nut torque after a few
hours of operation.
Avoid personal injury. Do not work under mower without supporting blocks to keep frame
from falling.
Be certain to clamp or securely support the Spindle Housing and sub-assemblies to prevent
injuries to hands and feet due to inadvertent dropping or falling over.
Always wear safety glasses and gloves to prevent eye and hand injury when chiseling or
hammering on metal components. Hardened material will chip unexpectedly.
An assembled spindle housing is quite heavy. Use a hoist or get help to handle them safely.
Lift carefully and properly using you legs to lift - NOT YOUR BACK.
BASIC TROUBLESHOOTING OF ELECTRONIC CONTROL VALVE
CONTROL HANDLE
If your control handle does not operate, recheck your installation.
Common problems are listed below.
1. Check electrical supply with a voltmeter. Connect the positive lead from the meter to the red wire that
supplies power to the handle and connect the other lead to the frame of the vehicle. Reading should be 1214 volts. Be certain that the ground wire from handle is securely connected to the frame of the vehicle.
2. Check for power at valve or load. Connect positive lead to each of the wires that supply the load, connect
the other lead to vehicle ground. Operating buttons on handle should turn each wire on/off, 12-14 volts.
3. Check for proper grounding of valve or load. Connect positive lead to the valve block or to the ground
connection of the load, connect the other lead to the vehicle frame (ground). There should be little or no
voltage present. If there is a reading of more than 1/2 volt, ground between valve or load and the frame of
vehicle is bad.
4. If voltage is present at coil terminal and ground connection is good, check to see if solenoid coil is being
energized by touching the large nut on the top of the coil with a screwdriver or small wrench. When coil is
energized, the tool will lightly stick to the top of the coil until turned off.

TO THE OWNER/OPERATOR/DEALER
To keep your implement running efficiently and safely, read your manual thoroughly and follow these directions
and the Safety Messages in this Manual. The Table of Contents clearly identifies each section where you can
easily find the information you need.
The OCCUPATIONAL SAFETY AND HEALTH ACT (1928.51 Subpart C) makes these minimum safety requirements of tractor operators:
REQUIRED OF THE OWNER:
1. Provide a Roll-Over-Protective Structure that meets the requirements of this Standard; and
2. Provide Seat belts that meet the requirements of this paragraph of this Standard and SAE J4C; and
3. Ensure that each employee uses such Seat belt while the tractor is moving; and
4. Ensure that each employee tightens the Seat belt sufficiently to confine the employee to the protected
area provided by the ROPS
REQUIRED OF THE OPERATOR:
1. Securely fasten seat belt if the tractor has a ROPS.
2. Where possible, avoid operating the tractor near ditches, embankments, and holes.
3. Reduce speed when turning, crossing slopes, and on rough, slick, or muddy surfaces.
4. Stay off slopes too steep for safe operation.
5. Watch where you are going - especially at row ends, on roads, and around trees.
6. Do not permit others to ride.
7. Operate the tractor smoothly - no jerky turns, starts, or stops.
8. Hitch only to the drawbar and hitch points recommended by the tractor manufacturer.
9. When the tractor is stopped, set brakes securely and use park lock, if available.
