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.
If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax

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.
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)
Practice all usual and customary safe working precautions and above all---remember safety is
up to YOU
. Only YOU can prevent serious injury or death from unsafe practices.
READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or
death may occur unless care is taken to follow the warnings and instructions stated in the
Safety Messages. Always use good common sense to avoid hazards.
(SG-2)

Engine Exhaust, some of its constituents, and certain vehicle components contain or emit
chemicals known to the state of California to cause cancer and birth defects or other
reproductive harm.
(SG-30)
Battery posts, terminals and related accessories contain lead and lead compounds,
chemicals known to the state of California to cause cancer, birth defects or other
reproductive harm.
(SG-31)
The rotating parts of this machine continue to rotate even after the PTO has been turned off.
The operator should remain in his seat for 60 seconds after the brake has been set, the
PTO disengaged, the tractor turned off, and all evidence of rotation has ceased.
(S3PT-10)
“Wait a minute...Save a life!”
Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.
Release of the control lever or mechanical failure will result in the Implement falling and
possible injury or death. Always securely block up the Implement before crawling
underneath to perform repairs and service.
(S3PT-19)
Never operate the Tractor or Implement until you have read and
completely understand this Manual, the Tractor Operator’s Manual, and
each of the Safety Messages found in the Manual or on the Tractor and
Implement. Learn how to stop the tractor engine suddenly in an
emergency. Never allow inexperienced or untrained personnel 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.
Always read carefully and comply fully with the manufacturer’s
instructions when handling oil, solvents, cleansers, and any other
chemical agent.
(SG-22)
KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement
and possible serious injury or death.
(SG-24)
Never allow children to play on or around Tractor or Implement. Children can slip or fall off
the Equipment and be injured or killed. Children can cause the Implement to shift or fall
crushing themselves or others.
(SG-25)
NEVER use drugs or alcohol immediately before or while operating the
Tractor and Implement. Drugs and alcohol will affect an operator’s
alertness and coordination and therefore affect the operator’s ability to
operate the equipment safely. Before operating the Tractor or Implement,
an operator on prescription or over-the-counter medication must consult
a medical professional regarding any side effects of the medication that
would hinder their ability to operate the Equipment safely. NEVER
knowingly allow anyone to operate this equipment when their alertness or
coordination is impaired. Serious injury or death to the operator or others
could result if the operator is under the influence of drugs or alcohol.
(SG-27)
Prolonged operation may cause operator boredom and fatigue affecting safe operation.
Take scheduled work breaks to help prevent these potentially impaired operating
conditions. Never operate the Implement and Tractor in a fatigued or bored mental state
which impairs proper and safe operation.
(SG-32)
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.
Avoid contact with hot surfaces of the engine or muffler. Use gloves and eye protection
when servicing hot components. Contact with a hot surface or fluid can cause serious injury
from burns or scalding.
(SG-38)
Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up.
(SGM-09)
Always keep a careful lookout and use extreme care when working around utility and
municipal obstructions. Never allow the Mower to contact any utility, municipal, or other
type structure. Clearly mark all mowing obstructions and consult local utility providers for
a safe code of operation.
(SPU-5)
Do not operate the implement while wearing loose fitting clothing. Entanglement of the
clothing with the rotating elements can result in serious injury or even death. Stay clear of
all rotating elements at all times.
(SSP-03)
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)
Use extreme care when lowering or unfolding the implement’s wings. Make sure no
bystanders are close by or underneath the wings. Allow ample clearance around the
implement when folding or unfolding the wings. Use extreme caution around buildings or
overhead power lines.
(S3PT-05)
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)
Be sure you have adequate knowledge of the property you will be working on. Take time to
make yourself aware of any area underground lines or cables. Contact with buried lines or
cable could result in serious injury or death. If in doubt about buried utility lines call 811
before digging or 1-800-258-0808.
(SBH-6)
SAFETY
Equipment Operation Safety Instructions and Practices
Do not operate Mower if excessive vibration exists. Shut down PTO and the Tractor
engine. Inspect the Mower to determine the source of the vibration. If Mower blades are
missing or damaged replace them immediately. Do not operate the mower until the
blades have been replaced and the Mower operates smoothly. Operating the Mower with
excessive vibration can result in component failure and broken objects to be thrown
outward at very high velocities. To reduce the possibility of property damage, serious injury,
or even death, never allow the Mower to be operated with blades missing.
(SFL-4)
Operate this Equipment only with a Tractor equipped with an approved rollover-protective system (ROPS). Always wear seat belts. Serious injury or
even death could result from falling off the tractor--particularly during a turnover
when the operator could be pinned under the ROPS.
(SG-7)
BEFORE leaving the tractor seat, always 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)
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.
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)
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)
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)
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.
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)
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.
(SGM-08)
Do not mow with two machines in the same area except with Cab tractors with the windows
closed.
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)
Do not operate or pull the mower into standing water. When uplift or fan type mower blades
contact water they can be severely deflected downward causing possible failure of blade
resulting in serious boldly injury to the operator or bystanders.
(SGM-15)
Use extreme caution when raising the Mower above ground level. Stop the Blades from
turning when the Mower is raised and passersby are within 100 yards. Raising the
Mower exposes the Cutting Blades which creates a potentially serious hazard and can
cause serious injury by objects thrown from the Blades or by contact with the Blades.
Rotary 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;
-Mower sections or Wings are running close to and parallel to the ground without exposed
Blades;
-Passersby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material such as rocks, cans,
glass, and general debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could be struck
by the blades, the area should be: inspected and large debris removed, mowed at an
intermediate height, inspected, closely with any remaining debris being removed, and
mowed again at desired final height. (This will also reduce power required to mow, reduce
wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and
make the final cut more uniform).
(SRM-01)
Do Not attempt to raise or lower the implement wing unless the Implement tongue is
securely attached to the Tractor drawbar. The Implement could tip over and cause
equipment damage and possible serious injury or death. Raise or Lower the mower wing
only while seated in the Tractor operator’s seat with the seat belt securely fastened.
(SRM-2)
Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline
which will cause accelerated wear and breakage of drive train components and could result
in possible injury from the separated Driveline sections.
(SRM-04)
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)
DO NOT allow any person under a folded wing unless wing is securely
locked up or supported. DO NOT approach the Implement unless the
Tractor is turned off and all motion has ceased. Never work under the
frame work, or any lifted component unless the implement is securely
supported or blocked up. A sudden or inadvertent fall by any of these
components could cause serious injury or even death.
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)
Always shut the Tractor completely down, place the transmission in park, and set the
parking brake before you or anyone else attempts to connect or disconnect the Implement
and Tractor hitches.
(S3PT-15)
When attaching the Implement input driveline to the Tractor PTO, it is important that the
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement.
(S3PT-17)
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury.
(S3PT-18)
Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift
the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the
tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue
Jack for lifting the Implement only. Overloading the Tongue Jack can cause failure with
possible serious bodily injury or even death.
(STI-04)
On a fully-assembled unit, do not remove the Wing Retaining Strap until hoses are attached
to the tractor and the Wing Cylinders are filled with oil. Lower the Wings slowly and
carefully. Keep bystanders away during operations.
(STI-05)
Connecting or Disconnecting Implement 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)
Allow sufficient clearance for the Implement to swing outward while turning. Implements
carried behind the Tractor will swing outside the tire path when making turns. Contacting a
solid object while turning will cause equipment damage and possible injury.
(S3PT-20)
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clearly visible and legible. When transporting the
Equipment use the Tractor flashing warning lights and follow all local
traffic regulations.
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.
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)
Be particularly careful when transporting the Implement using the tractor. Turn curves or
go up or down hills only at a low speed and at a gradual steering angle. Make certain that
at least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow
down on rough or uneven surfaces.
(STI-01)
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement may overturn.
(STI-02)
Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH.
Secure the Implement for transport before traveling on public roads. For pull-type
Implements, secure the center axle using cylinder stops or transport pin and properly attach
a safety chain between the Implement and Tractor. Secure wings in upright position on
folding Implements using wing transport locks.
(STI-7)
Always keep a careful lookout and use extreme care when working
around overhead obstructions and electrical power lines. The
Implement wing can be over 10 feet high. Never allow the Implement
wing to come within 10 feet of any power line.
(STI-8)
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)
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)
Relieve hydraulic pressure prior to doing any maintenance or repair work
on the Implement. Place the Implement on the ground or securely
blocked up, disengage the PTO, and turn off the tractor engine. Push

This Rotary Cutter is designed with care and built with quality materials by skilled workers. Proper assembly,
maintenance, and operating practices, as described in this manual, will help the owner/operator get years of
satisfactory service from the machine.
The purpose of this manual is to familiarize, instruct, and train. The Assembly Section instructs the owner/
operator in the correct assembly of the Mower using standard and optional equipment. The Parts Listing
section is designed to familiarize the owner/operator with replaceable parts on the Mower. This section
provides exploded assembly drawings of each mower component illustrating each piece and the
corresponding part number.
Careful use and timely service save extensive repairs and costly downtime losses. The Operation and
Maintenance Sections of the manual train the owner/operator how to work the Mower correctly and attend to
appropriate maintenance. The Trouble Shooting Guide helps diagnose difficulties with mower and offers
solution to the problems.
Safety is of primary importance to the owner/operator and to the manufacturer. The first section of this manual
includes a list of Safety Messages, that, if followed, will help protect the operator and bystanders from injury or
death. Many of the Safety Messages will be repeated throughout the manual. The owner/operator/dealer
INTRODUCTION
should know these Safety Messages before assembly and be aware of the hazards of operating this blade
during assembly, use, and maintenance. The Safety Alert Symbol combined with a Signal Word, as seen
below, is intended to warn the owner/operator of impending hazards and the degree of possible injury faced
when operating this machine.
Rhino typically offers three types of shielding to protect the operator, passerby, livestock, and property from
thrown objects... deflectors, single chain guards, and double chainguard. Shielding should be selected based
on the intended use of the mower. Double chainguards or deflectors should be used for highway, right-of-way,
parks or greenbelt mowing or all other mowing where human dwellings, vehicles, or livestock could be within
300 feet of the mower. Chainguards are more durable, provide a longer service life and require less
maintenance and replacement than deflectors. Single chainguards may be sufficient for agriculture and other
mower use only where passersby or property are not within 300 feet of the mower during operation.
No shielding is 100% effective in preventing thrown objects. The possibility of injury and property damage from
this hazard can be substantially reduce by selecting proper shielding, maintaining the mower and shielding in
good operational condition, inspecting the area for foreign debris before mowing, operating the mower at a
minimum cutting height of 4”, and keeping persons at a minimum distance of 300 feet from the mower at all
times during operation.

On a fully assembled unit, do not release the Wing Retaining Strap until the hoses are
attached to the tractor and the Wing Cylinders are filled with oil. Always keep bystanders
away while raising and lowering the wings
To lower the wings, hook the hydraulic hoses to the tractor. From the Operators
Seat use the tractor hydraulic control levers to fill wing cylinders with oil (Refer to
Operation Section). Keep coworkers and bystanders away from the implement
while filling. For implements with the wings in the raised or transport position, filling the cylinders should raise the wings slightly and loosen the wing retaining
lock. DO NOT release the wing Transport Bar/Latch if there is a force on the
lock. Use tractor hydraulic control levers to lower the wing(s). Continue to hold the
control lever until both wings are down and the wing cylinders are fully retracted
or extended. Continue to cycle the cylinders several times by raising and lowering
the wings fully to remove any trapped air. If there is sponginess during the raising
cycle, this may indicate that air is entrapped in the hydraulic circuit. Continue to
cycle the cylinders until all sponginess is removed.
The implement wings should lower slowly when they are allowed to float down
and are not powered down. This is a safety feature built into the system. If the
wings fall rapidly, have the cylinders repaired before operating the implement.

DEALER SET-UP INSTRUCTIONS
The mower as received from the factory is virtually completely assembled and requires minimum time to
complete assembly ready for sale.
ASSEMBLY
ASSEMBLY
Select a suitable work area large enough to allow for lowering of the wings. Use extreme caution when
connecting the mower to the tractor. The mower should be securely resting at ground level or setting on blocks.
Keep hands and feet from under the mower deck and clear of pinch points between the tractor hitch arms and
mower pins.
1. Use the implement jack to raise the implement tongue until it is even with the tractor drawbar. Insert the
jack into the jack adapter in the implement tongue and swivel it so that it is vertical. Follow the instructions
on the jack. Install the jack retaining pin. Measure the height of the tractor drawbar and raise the implement
tongue to the same height.
2. Make sure the tractor PTO is the correct speed and shaft size for the implement. Ensure the drawbar is
extended the proper distance from the Tractor PTO shaft for desired PTO speed; 540 PTO is 14” and for
1000 PTO speed the distance is 16”
3. Carefully back tractor to mower. Do not allow coworkers or bystanders between the tractor and the
implement while backing. When dismounting the tractor ALWAYS shut down the tractor, disengage the
PTO, and set the parking brake before dismounting.
4. Install the retaining bolt through tongue clevis and tractor drawbar. The implement tongue is very heavy.
Make any height adjustments using the implement jack. Place two 1” flatwashers (1) positioned under top
lip of tongue clevis and to the top of drawbar. Insert a 1” diameter grade 5 or 8 bolt (2) through clevis and
drawbar and retain in position with a 1” locknut (3). Tighten the locknut securely but do not overtighten,
which could spring or break the clevis. NOTE: NEVER attach mower to the tractor with a pin not having a
nut.
ASSEMBLY
5. Install the implement tow chain to a secure location on the tractor.
6. Attach proper hydraulic couplers to implement hose ends. Insert the wing hose quick disconnect couplers
into tractor hydraulic remotes.
7. Mount tractor, fasten your seatbelt and start engine. From the operators seat use the tractor hydraulic
control levers to fill wing cylinders with oil. Filling the cylinders should retract the wings slightly to their
minimum closed width. Continue to apply pressure to cylinders for at least 10 seconds to assure they have
filled with fluid.
Keep coworkers and bystanders away from the implement while filling.
8. Remove retaining bracket from end yoke of
main driveline. Remove main driveline from
mower and place on ground or hard surface.

ASSEMBLY
10. Stand between the wings of the implement and remove nuts holding the shipping strap in place and
remove strap.
Do not stand outside of the wing to remove the shipping strap, if the wing fell it could kill you.
Make sure no bystanders are under the wing or in the area where the wing could fall.
Reinstall nut and flatwasher to retain side skirt.
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)
11. Filling the cylinders with oil should raise the
wings slightly and loosen the wing Transport
Bars/Latches retaining pin. NOTE: DO NOT
release the wing Transport Bar/Latch if there is
a force on the pin. If there is a force holding the
Transport Bar/Latch in place, use the tractor
hydraulic control levers while in the tractor seat
to raise the wings until the force is relieved.
Release the Transport Bar/Latch and secure in
the storage location. Figure AsmP-R-0119
12. From the tractor seat use the tractor hydraulic
control levers to lower the wing(s).
ASSEMBLY
Keep coworkers and bystanders away from the implement while filling.
13. Continue to hold the control lever until both wings are down and the wing cylinders are fully extended.
Continue to cycle the cylinders several times by raising and lowering the wings fully to remove any trapped
air. If there is sponginess during the raising cycle, this may indicate that air is trapped in the hydraulic
circuit. Continue to cycle the cylinders until all sponginess is removed.
14. Test to make sure the wings lower slowly when they are allowed to float down and are not powered down.
This is a safety feature built into the system. If the wings fall rapidly, have the hydraulic system or cylinders
repaired before operating the implement.
When attaching the Implement input driveline to the Tractor PTO, it is important that the
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement.
(S3PT-17)
DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be
dirt free and greased for attachment.
To connect the mower driveline to the tractor PTO
output shaft, pull the driveline yoke collar back and
align the grooves and splines of the yoke with those
of the PTO shaft. Push the driveline yoke onto the
PTO shaft, release the locking collar, and position
the yoke until the locking collar balls are seated
onto the PTO shaft. Push and pull the driveline
back and forth several times to ensure a secure

Safety Deflectors are standard equipment. Single and double chain guards are available as extra equipment at
extra cost. Servis-Rhino recommends mowers be equipped with deflectors or double chain guards for all
mowing purposes. Single chain guards may be used for agriculture purposes only and are specifically not
recommended for highway, right-of-way, parks or greenbelt mowing.
Safe operation of the unit is the responsibility of a qualified operator. A qualified operator has read and
understands the implement and tractor Operator’s Manuals and is experienced in implement and tractor
operation and all associated safety practices. In addition to the safety messages contained in this manual,
safety signs are affixed to the implement and tractor. If any part of the operation and safe use of this
equipment is not completely understood, consult an authorized dealer for a complete explanation.
If the operator cannot read the manuals for themselves or does not completely understand the operation of the
equipment, it is the responsibility of the supervisor to read and explain the manuals, safety practices, and
operating instructions to the operator.
Safe operation of equipment requires that the operator wear approved Personal Protective Equipment (PPE)
for the job conditions when attaching, operating, servicing, and repairing the equipment. PPE is designed to
provide operator protection and includes the following safety wear:
PERSONAL PROTECTIVE EQUIPMENT (PPE)
•Always Wear Safety Glasses
•Hard Hat
•Steel Toe Safety Footwear
•Gloves
•Hearing Protection
•Close Fitting Clothing
•Respirator or Filter Mask (depends on
operating conditions) OPS-U- 0002
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.
The tractor must be equipped with a Roll-Over-Protective-Structure (ROPS) (tractor cab or roll-bar) and seat
belt to protect the operator from falling off the tractor, especially during a roll over where the driver could be
crushed and killed. Only operate the tractor with the ROPS in the raised position and seat belt fastened.
Tractor model not equipped with a ROPS and seat belt should have these life saving features installed by an
authorized dealer. OPS-U- 0003
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)
3.2 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
removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO
with the PTO master shield missing or in the raised position. OPS-U- 0004
3. TRACTOR REQUIREMENTS
The tractor used to operate the mower must have the power capacity to lift, pull, and operate the Power Take
Off (PTO) at the mower’s rated speed while traveling at a ground speed between 2 and 5 MPH. Operating the
mower with a tractor that does not meet the following requirements may cause tractor or mower damage and
be a potential danger to the operator and passersby.
Tractor Requirements and Capabilities
•ASABE approved Roll-Over Protective Structure (ROPS) or ROPS cab and seat belt.
The horsepower required to operate the mower depends on several operating factors including the vegetation
to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most
mowing conditions, the FL10 NITRO mower requires a tractor with a minimum of 40 HP and the FL15 NITRO
mower requires a tractor with a minimum of 50 HP. Operating the mower with a tractor that does not have
adequate power may damage the tractor engine. Exceeding 100 HP for a 540 RPM drive and 140 HP for a
1000 RPM drive may cause mower damage by overpowering the unit in heavy cutting conditions.
3.4 Drawbar
Constant Velocity and Standard Driveline.
Position the length of the drawbar from the end of the
tractor PTO shaft to the drawbar hitch hole according
to the operating speed of the mower. If the mower is
a 540 RPM unit, position the drawbar length from
shaft end to hitch hole at 14”. For 1000 RPM
mowers, set the drawbar length at 16” for 21 spline
1-3/8” mowers and at 20” for 1-3/4” 20 spline
OPERATION
mowers.
Pintle Hook Hitch-Optional Equipment
Drawbar length must be modified to obtain
dimension "A" (CV Driveline = 17" ± 2", Standard
Driveline = 19” ± 2").
3.5 Tractor Hydraulics
The mower center section and each wing are positioned with hydraulic cylinders that are operated by the
tractor hydraulic pump. The tractor must have a minimum of 2 hydraulic control valves devoted to the mower
unless the tractor is fitted with a 3-spool control valve (extra equipment).
A 3-spool control valve is required if the tractor is equipped with a single valve and is recommended for those
with two valves so that the center section and each wing can be controlled independent of one another. Refer
to the Assembly Section of this manual for properly equipping the tractor with a 3-spool control valve. Tractors
equipped with three hydraulic ports can position the center section and each wing independently with no extra
equipment. If the tractor is equipped with only two hydraulic ports and a 3-spool control valve is not used, the
wings cannot be operated independently and will raise and lower at different speeds.
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
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.
Tractor tires should be set a minimum of 60”(1.5
mm) apart measured from inside of tire to inside of
tire. Refer to the tractor Operator’s Manual or
consult an authorized dealer for instructions to
change tractor tire spacing. OPS-R- 0062
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)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death.
