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

General Safety Instructions and Practices
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.
SAFETY
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.

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)
Operator Safety Instructions and Practices
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 and Implement without supervision. Make sure the
operator has fully read and understood the manuals prior to operation.
(SG-4)
The operator and all support personnel should wear hard hats, safety
shoes, safety glasses, and proper hearing protection at all times for
protection from injury including injury from items that may be thrown by
the equipment. (SG-16)
SX15 01/09

Safety Section 1-3
SAFETY
For your protection while operating or servicing equipment, wear relatively tight and belted
clothing to avoid entanglement in moving parts. Tie up and protect long hair that could
become entangled in machinery. Remove all jewelry including necklaces, rings and
watches which can get caught in machinery or on corners or edges of the equipment.
Serious injury can result from entanglement with the machinery. (SG-42)
SAFETY
SAFETY
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE
PERMANENT HEARING LOSS! Tractors with or without an Implement
attached can often be noisy enough to cause permanent hearing loss.
We recommend that you always wear hearing protection if the noise in
the Operator’s position exceeds 80db. Noise over 85db over an
extended period of time will cause severe hearing loss. Noise over 90db
adjacent to the Operator over an extended period of time will cause
permanent or total hearing loss. NOTE: Hearing loss from loud noise
[from tractors, chain saws, radios, and other such sources close to the
ear] is cumulative over a lifetime without hope of natural recovery. (SG-I7)
Always read carefully and comply fully with the 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)

Safety Section 1-4
SAFETY
Use extreme caution when getting onto the Implement to perform repairs, maintenance and
when removing accumulated material. Only stand on solid flat surfaces to ensure good
footing. Use a ladder or raised stand to access high spots which cannot be reached from
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)
(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)
Repeated or substantial breathing of hazardous dusts, including
crystalline silica, could cause fatal or serious respiratory disease including
silicosis. Concrete, masonry, many types of rock, and various other
materials contain silica sand. California lists respirable crystalline silica as
a substance known to cause cancer. Operation of this equipment under
certain conditions may generate airborne dust particles that could contain
crystalline silica. In those conditions, personal protective equipment
including an appropriate respirator must be used. If excessive dust is
generated, a dust collection or suppression system should also be used
during operation. (SG-41)
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)
SX15 01/09

Safety Section 1-5
SAFETY
DO NOT operate this Implement on a Tractor that is not properly maintained. Should a
mechanical or Tractor control failure occur while operating, immediately shut down the
Tractor and perform repairs before resuming operation. Serious injury and possible death
could occur from not maintaining this Implement and Tractor in good operating condition.
SAFETY
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)
Equipment Operation Safety Instructions and Practices
SAFETY
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 is wider than the Tractor. Be careful when operating or transporting this
equipment to prevent the Implement from running into or striking sign posts, guard rails,
concrete abutments or other solid objects. Such an impact could cause the Implement and
Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.
Never allow the Implement to contact obstacles. (S3PT-12)
Be sure you have adequate knowledge of the property you will be working on. Take time to
make yourself aware of any area underground lines or cables. Contact with buried lines or
cable could result in serious injury or death. If in doubt about buried utility lines call 811
before digging or 1-800-258-0808. (SBH-6)
Do not operate Mower if excessive vibration exists.
Shut down PTO and the Tractor
engine. Inspect the Mower to determine the source of the vibration. If Mower blades are
missing or damaged replace them immediately.
Do not operate the mower until the
blades have been replaced and the Mower operates smoothly. Operating the Mower with
excessive vibration can result in component failure and broken objects to be thrown
outward at very high velocities. To reduce the possibility of property damage, serious injury,
or even death, never allow the Mower to be operated with blades missing. (SFL-4)
Operate this Equipment only with a Tractor equipped with an approved rollover-protective system (ROPS). Always wear seat belts. Serious injury or
even death could result from falling off the tractor--particularly during a turnover
when the operator could be pinned under the ROPS. (SG-7)
SX15 01/09

Safety Section 1-6
SAFETY
BEFORE leaving the tractor seat, always engage the brake and/or set
the tractor transmission in parking gear, disengage the PTO, stop the
engine, remove the key, and wait for all moving parts to stop. Place the
tractor shift lever into a low range or parking gear to prevent the tractor
from rolling. Never dismount a Tractor that is moving or while the engine
is running. Operate the Tractor controls from the tractor seat only. (SG-9)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
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)
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)
SX15 01/09

Safety Section 1-7
SAFETY
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and
responsible can operate the implement with adult supervision, if they
have read and understand the Operator’s Manuals, been trained in
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily. (SG-11)
SAFETY
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)
SAFETY
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
100 yards(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 100 yards
of mower. (SGM-02)
SX15 01/09

Safety Section 1-8
SAFETY
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)
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. (SGM-11)
SX15 01/09
© 2009 Alamo Group Inc.
Safety Section 1-9
SAFETY
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)
SAFETY
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.
SAFETY
-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. (SPU-1)
SX15 01/09
© 2009 Alamo Group Inc.
Safety Section 1-10
SAFETY
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 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable
condition;
-Mower sections or Wings are running close to and parallel to the ground without exposed
Blades;
-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)

SAFETY
Connecting or Disconnecting Implement Safety Instructions and
Practices
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.
SAFETY
(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)
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)
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)

Safety Section 1-12
SAFETY
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)
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)
SX15 01/09

Safety Section 1-13
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
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. (STI-03)
SAFETY
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)
Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH. (STI-06)
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)

are is 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)
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)
Do not modify or alter this Implement. Do not permit anyone to modify or alter this
Implement, any of its components or any Implement function. (SG-8)
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death. (SG-14)
Never attempt to lubricate, adjust, or remove material from the Implement while it is in
motion or while tractor engine is running. (SG-20)

INTRODUCTION
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
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.
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.

INTRODUCTION
INTRODUCTION
Your Mower is designed primarily for weed and grass control, shredding row crops such as cotton and corn
stalks, and cutting small brush up to 2" in diameter. With proper maintenance as described in this manual, your
Mower will provide you with years of dependable service with a minimum of repairs.
It is recommended that all operators of this implement read this manual or be instructed of its contents as to
safety, proper operation, and maintenance before beginning operation.
Your Mower has been assembled to operate with a tractor PTO input speed of either 540 or 1000 RPM,but not
both. This machine is designed for use with tractors rated 50 HP (37kW) to 130 HP (98kW).
When ordering parts for the Gearboxes and the Drivelines, be sure to specify the serial number. The serial
number is located outside of the right Tongue attaching Plate on the center Mainframe section.
Chain Guards are extra equipment. Deflectors, Driveline Integral Shields and Gearbox Shields are standard
equipment and are to be used at all times.
To place the warranty into effect, fill out the warranty card in full, giving all the requested information, and mail
promptly. Be sure to give the serial number of this Mower.
For Non-Agricultural use, OSHA, ASAE, SAE, and ANSI standards require the use of Chain
Guards, Deflectors, or Solid Skirts at all times. The Cutter manufacturer strongly
recommends the use of Chain Guards, Deflectors, or Solid Skirts for Agricultural purposes
as well to reduce the risk of property damage, serious bodily injury, or even death from
objects thrown out by or from contact with the Cutting Blades.
At least 20% of the tractor’s total weight must be on the front tires with the Cutter lifted to
provide adequate traction for safe steering under good conditions. Slow down on hills,
rough terrain, and curves.
Front and rear, and left and right are determined by the normal direction of travel (the same as on your
automobile).

HYDRAULIC SYSTEM ASSEMBLY
1. This unit can be operated on any tractor which has at least two remote outlets.
IMPORTANT: Remote outlets connected to wings cylinders must have a float detent position on the control
lever. If not the tractor must be equipped with an external valve bank which has float detent positions.
2. If tractor has only two outlets, one must be used to control the center axle and the other to control both
wings by placing a tee in the hoses between the cylinders. NOTE: When both wing hydraulic cylinders
are operated by one valve spool, independent control of wings is not possible. When valve is actuated to
raise wings, there is no control over which wing will raise first. If independent control is required, tractor
must be equipped with an external three-spool valve bank.
3. If a three-spool valve bank is required, then assemble it on a mounting bracket and install on the tractor
fender at desired location. (See valve bank plumbing diagram for further details).

ASSEMBLY
HYDRAULIC THREE-SPOOL VALVE ACCESSORY (EXTRA EQUIPMENT)
ASSEMBLY
An open or closed center 3-spool valve is available as extra equipment . (FIGURE Asm-R-0180)
1. If a hydraulic three-spool valve is used the valve must be matched to the tractors hydraulic system (open
center or closed center) and must have two spools which have detent position which allows the wing
cylinders to float. When installing the control valve into the tractor’s hydraulic system, consult the
operators manual of the tractor to determine the type of hydraulic system used. Definitions of closed and
open center system follows:
Open Center Hydraulic System - This system pumps oil through the circuit continually. When a resistance to
flow is created in the line or valve, the pressure builds up until, at a certain point, the relief valve opens to pass
the oil back to the tank. This is a constant flow, variable pressure system with a relief valve required.
Closed Center System - This system holds a constant pressure in the line, and when an obstruction to flow
occurs, the pump stops pumping. No relief valve is required or provided. This is a variable volume, fixed
pressure system.
IMPORTANT: If a closed center valve is installed in an open center system, there is no relief valve provided.
When the oil flow is blocked and there is no relief valve, the pump either stops, breaks, a hose is blown or the
engine stalls. Hose failure or a pump shaft failure is most common.
If an open center valve containing a relief valve is installed in a closed center system, the pump cut off
pressure, over 2200 psi, will exceed that of the relief valve and pump oil continually over the relief valve. This
will create a continuous load against the motor with all of this energy going to heat. This in turn, will heat up the
hydraulic system, which is usually the transmission and could result in damage to entire transmission of the
tractor.
NOTE: If there is any doubt as to which type system your tractor has, check with your local tractor dealer. If
there is any doubt as to what type valve bank you have, remove large hex plug from outlet side of valve. If plug
is long as pictured in valve it is a closed center. A closed centered valve will utilize a plug with an extension
past the threads. Which provides a blockage to the return flow, thus allows for closed center function. The
valve can be converted to an open center valve by removing the extension with a saw.
IMPORTANT: Do not connect return line from valve bank into remote outlet unless recommended by your
tractor manufacturer. Damage to valve can result if remote outlet control lever is actuated to pressurize return
line. Always connect return line directly into tractor system reservoir.

OPERATION
The horsepower required to operate the mower depends on several operating factors including the vegetation
to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most
mowing conditions the SX15 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 130 HP may cause
mower damage by overpowering the unit in heavy cutting conditions.
OPERATION
3.3 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
3.4 Drawbar
The tractor drawbar must be positioned at a certain
length based on the operating speed of the mower
for proper driveline operation. If the mower is a
540 RPM unit, position the drawbar length from
shaft end to hitch hole at 14”.
Ensure that the drawbar is rated to carry the
tongue weight of the mower.
Pintle Hook Hitch-Optional Equipment
Drawbar length must be modified to obtain
dimension "A" (CV Driveline = 17" ± 2").
OPS-R- 0061_F

Operation Section 4-6
OPERATION
3.5 Power Take Off (PTO)
Depending on the unit, the mower is designed to operate at a PTO speed of 540 RPM. Most tractors operate
at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and
tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those
operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft.
Note: Refer to the tractor owner’s manual for instructions to change PTO speeds on models that operate at
more than one speed.
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the 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)
3.6 Tire Spacing
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
SX15 01/09
© 2009 Alamo Group Inc.
Operation Section 4-7
OPERATION
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an
over-running clutch must be used between the PTO output shaft and the driveline of the mower. An
authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006_B
OPERATION
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
OPERATION
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. (SG-10)
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

5. STARTING THE TRACTOR
The operator must have a complete understanding of the placement, function, and operational use of all
tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized
dealer for tractor operation instructions if needed.
Essential Tractor Controls:
• Conduct all pre-start operation inspection and service according to the tractor operator’s manual.
• Make sure all guards, shields, and other safety devices are securely in place.
• The parking brake is on.
• The PTO control lever is disengaged.
• The 3-point hitch control lever is in the lowered position.
• The hydraulic remote control levers are in the neutral position.
• The tractor transmission levers are in park or neutral.
Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and
belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.
After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden
and unexpected tractor movement. OPS-U-0028
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
Start tractor only when properly seated in the Tractor seat. Starting a
tractor in gear can result in injury or death. Read the Tractor operators
manual for proper starting instructions. (SG-13)
6. CONNECTING THE MOWER TO THE TRACTOR
Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at
ground level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points
between the tractor hitch arms and mower pins. OPS-R-0001

• Locate the light control lever.
• Locate the engine shut off control.
• Locate the brake pedals and the clutch.
• Locate the PTO control.
• Locate the 3-point hitch control lever.
• Locate the hydraulic remote control levers.
Before starting the tractor ensure the following:
OPERATION
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)
6.1 Connecting the Mower Tongue to the Tractor
OPERATION
1.
2.
3.
4.
5.
6.
Ensure the tractor is equipped with the
correct PTO shaft and the drawbar is set at
the correct length.
Using the parking jack, position the tongue
clevis to the height of the tractor drawbar.
Adjust the mower tongue clevis to be level
and parallel with the tractor drawbar using the
control rod connecting the mower tongue
clevis to the deck.
Board the tractor and start the engine. Back
the tractor to the mower aligning the drawbar
hitch hole with the mower tongue clevis. Turn
off the tractor engine, place the tractor in
park, and set the parking brake before
dismounting.
To attach the mower, 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 overtighten which could spring or break
the clevis. NEVER attach mower to the
tractor with a pin not having a nut.
Securely attach the mower safety chain to the
tractor drawbar or drawbar support frame.
Lower the jack until the tongue is completely
supported by the drawbar. Remove jack from
the tongue and place on storage bracket of
mower.
Safety Tow Chain
If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the
gross weight of the mower must be connected between the tractor and mower. This will help control the
implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached
to a secure location on the tractor and not to an intermediate support. After connecting both ends of the safety
chain, drive the tractor to the right and left to check for proper chain length. Adjust length as necessary and
allow only enough slack in the chain to make a maximum turn in both directions. When not in use, store the
safety chain to protect it from mud or standing water by wrapping the chain around the tongue. Replace the
safety chain if one or more links or end fittings are broken, stretched or otherwise damaged or deformed.

OPERATION
6.2 Connecting Mower Hydraulic Lines to the Tractor
With the tractor shut down and secured in position, relieve hydraulic pressure from the tractor by moving the
control levers back and forth several times or placing the levers in the float position.
When connecting the mower hydraulic lines, keep hoses, quick couplers, and swivels free of contamination.
Never leave a disconnected hose end open and cap the tractor hydraulic outlet ports when not in use. If the
tractor ports or mower hydraulic hose ends become contaminated, wipe clean with a rag before connecting.
Operating Mower Hydraulics with Three Tractor Hydraulic Ports
Operating Mower Hydraulics with Two Tractor Hydraulic Ports
The lines that operate the wings must be plumbed together and will be controlled using one hydraulic control
valve and the center section with the remaining control valve. Ensure that the operator is aware that each wing
cannot be controlled independently nor will they raise and lower simultaneously.
Operating the Mower Hydraulics with a 3-Spool Hydraulic Control Valve (Extra Equipment)
Ensure the valve matches the hydraulic operating system of the tractor (open or closed center). Refer to the
Assembly Section for additional information on equipping the tractor with a 3-spool control valve.
Mount the valve bank to a tractor fender or other accessible location. Connect valve bank inlet and outlet lines
to outlets of the same tractor hydraulic port. Connect the mower hydraulics to the control valve bank with the
center section line to the right port. Connect the wing cylinder lines to the control valve positioned to
correspond with the left and right wing.
To activate the 3-spool hydraulic control valve, tie the tractor’s hydraulic control lever back to keep hydraulic oil
continuously fed to the valve bank.
SX15 01/09
© 2009 Alamo Group Inc.
Operation Section 4-11
OPERATION
Connect one hose into each hydraulic port. Connect lines to correspond with position of hydraulic control
levers.
OPERATION
Hydraulic Line Support
After connecting the mower hydraulic lines to the tractor, support the hoses with the equipped brackets.
Ensure that hoses do not contact the driveline, do not bind while turning, and do not become pinched or
kinked.
OPERATION
Hydraulic Cylinder Priming
Hydraulic Cylinders must be filled with hydraulic oil before removing the wing transport braces to lower the
mower wings. Hydraulic cylinders and lines are filled by holding the valve control levers in the raised position
until the cylinders fully retract (wing cylinders) and extend (center cylinder). Place control levers in the float
position and repeat process a second time. Ensure wings are entirely supported by the cylinders before
removing the transport bars. NEVER drive out bar pins and NEVER remove bars that have tension on them.
7. 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)
7.1 Setting Deck Height
LEVELING DECK CENTER SECTION
1.
2.
3.
4.
Place the tractor and mower on a level
surface and lower both wings.
Use the center section hydraulic cylinder to
set the mower at approximately 3/4” above
the desired cutting height. The additional
height is necessary so that after the mower
has been leveled, the deck pitch can be set
such that the front of the mower is slightly
lower than the rear.
Shut down the tractor, place the transmission
in park, and set the parking brake before
dismounting.
Level the mower deck front to rear by
adjusting the leveling rods linking the tongue
to the rear axle. DO NOT allow feet or other
body part underneath the mower when making adjustments. To adjust rod length, loosen jamnut and
screw turnbuckles. To lower the front, lengthen the rods and to raise the front, shorten the rods. DO
NOT unscrew turnbuckles to the point that either rod threaded ends becomes disconnected which will
cause the mower to fall. Re-tighten jamnuts when deck is leveled. IMPORTANT: Alternate adjustments

Level the mower side to side by manipulating one lower lift arm length. On most tractors, at least one of
the lift arms is designed to allow for manipulation of its length. Shortening or extending will allow for deck
leveling from side to side.
LEVELING WING SECTIONS WITH CENTER
1.
7.2 Setting Deck Pitch
To facilitate safe and efficient operation, the mower
should be operated with the deck approximately
3/4” LOWER IN THE FRONT THAN THE REAR.
Operating the mower at this pitch will allow the
mower to cut the grass only once and requires less
work from the tractor. In addition, a more even
distribution of the clippings from the rear of the
mower will be achieved with this deck pitch.
Adjust the leveling rods linking the tongue to the
rear axle until the front of the mower is at least 3/4”
lower in the front that than the rear. To lower the
front, lengthen the leveling rods and to raise the
front shorten the leveling rods. IMPORTANT:
Adjust the leveling rods the same amount and
maintain equal tension in the rods. Improper
adjustment may cause rods to snap or bend.
Retighten the jamnuts after the deck pitch has been
set. OPS-R-0002-F

OPERATION
To level the wing sections with the deck
center, adjust the leveling screw between the
wing axle and the center axle. To lower the
wing, loosen the jamnut and shorten the
screw assembly, lengthen the screw
assembly to raise the wing. After wings are
leveled, retighten jamnuts to maintain
settings.
OPERATION
8. DRIVELINE ATTACHMENT
OPERATION
The driveline yoke and tractor PTO shaft must be
dirt free and greased for attachment.
To connect the mower driveline to the tractor PTO
output shaft, pull the driveline yoke collar back and
align the grooves and splines of the yoke with those
of the PTO shaft. Push the driveline yoke onto the
PTO shaft, release the locking collar, and position
the yoke until the locking collar balls are seated
onto the PTO shaft. Push and pull the driveline
back and forth several times to ensure a secure
attachment. OPS-R-0003_A
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)
8.1 Driveline Length Check
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury. (S3PT-18)
When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most
compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is
sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1”
clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a
minimum profile engagement of 7” must be maintained for Constant Velocity (CV) tube type driveline.
SX15 01/09

Operation Section 4-14
OPERATION
“Bottoming Out” Check Procedure
•
•
•
Note: If tractor has 540 RPM PTO adjusting drawbar to 16’ position will gain additional 2” of telescoping.
Engagement Check Procedure
•
With the driveline attached, position the mower to the point where the telescoping driveline is at its maximum
extension. Completely shut down the tractor and secure in position.
•
Mark the inner driveline shield 1/8” from the end of the outer shield.
•
Disconnect the driveline from the tractor and separate the two driveline halves.
•
Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline profiles were
engaged.
•
If the engaged length is less than 7” for a CV driveline and less than 6” for a non-CV driveline, the shaft is considered
too short and should be replaced with a longer shaft. Consult an authorized dealer to purchase the required driveline
length.
NOTE: If the driveline cannot be shortened and still maintain the required profile engagement, the operator must be made
aware of terrain conditions and avoid situations which pose a potential problem to avoid damaging the driveline or move
drawbar to 16” or 20” position for required clearance. OPS-R-0005_N
SX15 01/09

Operation Section 4-15
OPERATION
•
Disconnect driveline from the tractor and slide
the profiles together until fully compressed.
Place a mark on the inner shield 1/8” from the
end of the outer shield and reattach the
driveline to the PTO shaft.
With the PTO NOT TURNING, slowly drive the
tractor with mower attached through the
sharpest turn possible and watch shaft
movement. With the PTO NOT TURNING,
slowly drive the tractor with the mower attached
through the most severe terrain conditions
expected and watch shaft movement.
If the distance between the mark and the outer
shield becomes less than 2” at any point there is a potential problem bottoming out the driveline and the
driveline should be replaced with shorter driveline. Contact your local dealer or Technical Service for
proper directions. OPS-R-0004_J
OPERATION
8.2 Constant Velocity (CV) Driveline
Mowers are equipped with a Constant Velocity (CV) driveline, the maximum turning angle between the tractor
and mower must be determined to ensure the joint angle does not over-extend which can cause CV joint
damage. Constant Velocity joints enable the driveline to operate smoothly with no vibrations and clattering at
angles up to 80°. Angles greater than 80° will result in mechanical damage to the CV joint and mower
driveline.
OPERATION
The Constant Velocity joint must be lubricated every 20-40 hours of operation as specified in the Maintenance
Section. Failure to properly lubricate the joint will result in accelerated wear and joint component failure.
CV Driveline Maximum Angle Check Procedure
•
With the mower attached to the tractor and the driveline disconnected from the tractor PTO stub make
a hard left turn until there is approximately a 1" clearance between the left rear tractor tire and mower
frame or tongue.
• Stop and completely shut down the tractor. Place the tractor in Park and apply the Parking Brake before
dismounting.
• Check the CV joint at this maximum turning radius by holding the driveline yoke above the PTO shaft and
then angle the CV joint to its maximum angle. A minimum difference of 10 degrees between the center
line of the yoke and the PTO shaft must be maintained to ensure the joint will not be over angled. If the
joint cannot be angled at least 10°, there is a potential problem of over-angling the joint while making
sharp turns.
• Solutions: To ensure the joint is not damaged, check the following:
Check the drawbar length to ensure that it is at the proper length for the RPM speed of the mower.
Move the tractor rear tires wider apart to limit the tractor turning radius.
Position the mower at multiple angles and perform the above procedure. Determine the sharpest turning
radius that maintains a safe operating angle and note this position to the operator. OPS-R-0006_A
SX15 01/09

Operation Section 4-16
OPERATION
The Constant Velocity PTO driveline is HEAVY (70 lbs or greater) and Special Lifting
Procedures are recommended. Use lifting assistance such as mechanical assistance, two
people, and proper lifting techniques when connecting or installing the driveshaft to reduce
the possibility of back injuries.
9. PRE-OPERATION INSPECTION AND SERVICE
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)
Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners, worn
or broken parts, and leaky or loose fittings. Make sure all pins have
cotter pins and washers. Serious injury may occur from not maintaining
this machine in good working order. (SG-21)

10. 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
OPERATION
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
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)

Operation Section 4-26
OPERATION
10.1 Starting the Tractor
The procedure to start the tractor is model specific.
Refer to the tractor operator’s manual for starting
procedures for your particular tractor. Consult an
authorized dealer if the starting procedure is
unclear. Ensure the 3-point control lever is in the
lowered position and the PTO is disengaged before
starting the tractor. OPS-U-0033
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.
OPS-U- 0013
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
When operating down a hill or on wet or rain slick roads, the braking distance increases; use
extreme care and reduce your speed in these conditions. When operating in traffic, always
use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around
you and watch out for the other guy.
10.3 Operating the Mower Wings
Wings are positioned with hydraulic cylinders. It is recommended that the tractor be equipped with three
hydraulic ports or a 3-spool control valve be used so that each section can be controlled independently.
Ensure the hydraulic cylinders and lines are filled with oil by holding the valve control levers in the raised
position until the cylinders fully retract (wings) and extend (center). Only operate the mower with both wings
fully lowered, NEVER operate the mower with a raised wing. Wait until the blades are at a complete stop
before raising wings. OPS-R-0015

OPERATION
10.2 Brake and Differential Lock Setting
OPERATION
OPERATION
Transport Position
To raise mower wings, drive the unit to a level area
and retract the wing hydraulic cylinders. DO NOT
raise wings with the mower positioned on an
embankment or other inclined position to prevent
overturning the mower. After the wings are fully
raised, install transport lock braces to prevent wings
from inadvertently falling. NOTE: If the transport
lock braces can not be easily installed, lower the
mower wings and remove rod end of cylinder and
adjust the rod clevis in or out to match the transport
brace length.
The center of gravity is raised and the mower more
prone to tipping when the wings are in the raised
position. When transporting, only raise the center
section high enough to clear ground obstacles. OPS-R-0016
Operating Position
To lower the wings, remove the transport lock
braces and secure braces on storage bracket. DO
NOT drive out transport brace pins. The wing
cylinder may need to be retracted to remove tension
for brace removal. After removing brace bars,
extend wing hydraulic cylinders and fully lower
wings.
The valves operating wing cylinders should be
placed in the float position while mowing to allow the
mower to follow the contour of uneven terrain and to
prevent the wings from creeping up.
When
extending a wing over a ditch for mowing, place the
control valve lever detents in the center position.
This will give the mower more stability and prevent
the opposite wing from raising. DO NOT operate the mower with the valves in the detent position for extended
periods of time to prevent deck frame damage. OPS-R-0017

Operation Section 4-28
OPERATION
10.4 Driving the Tractor and Cutter
Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the
tractor and mower. Moving slowly at first will also prevent the tractor from rearing up and loss of steering
control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent
the operator from stopping quickly during an emergency. If the power steering or engine ceases operating,
stop the tractor immediately as the tractor will be difficult to control.
Drive the tractor with the 3-Point lift arms in the raised position and lock the control lever in the transport detent
position to prevent damage to the mower driveline and tongue when turning.
To avoid overturns, drive the tractor with care and at
safe speeds, especially when operating over rough
ground, crossing ditches or slopes, and turning
corners. Tractor wheel tread spacing should be
increased when working on inclines or rough ground
to reduce the possibility of tipping.
Use extreme caution when operating on steep
slopes. Keep the tractor in a low gear when going
downhill. DO NOT coast or free-wheel downhill.

OPERATION
Perform turns with the tractor and mower at slow
speeds to determine how the tractor with an
attached mower handles a turn. Determine the safe
speed to maintain proper control of the tractor when
making turns.
When turning with a towed
implement, the overall working length of the unit is
increased. Allow additional clearance for the mower
when turning..
OPERATION
OPERATION
10.5 Crossing Ditches and Steep Inclines
When crossing ditches with steep banks or going up
sharp inclines, it is possible that the main driveline
inner profile will penetrate into the outer housing to its
maximum depth until the assembly becomes solid
(driveline is at its extreme shortest length). This type
of abusive operation can cause serious damage to
the tractor and mower drive by pushing the PTO into
the tractor and through the support bearings or
downward onto the PTO shaft, breaking it off.
Damage resulting from over-collapse of the driveline’s inner profile and its outer housing
may allow the driveline to come loose from the Tractor which could cause bodily injury to the
operator or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020
NOTE: See Section 7.1 Driveline Length Check and “Bottoming Out” Check Procedure.
When contronted with an incline or ditch, do not
approach from an angle which is perpendicular or
straight on as damaged to over collapse of the
driveline may occur.
When crossing such terrain, the implement should
be fully lowered for a lower center of gravity and
added stability. OPS-R-0021
SX15 01/09
© 2009 Alamo Group Inc.
Operation Section 4-30
OPERATION
Inclines and ditches should be approached along a
line which is at an angle as shown. This type of
path will reduce the possibility of over-collapse of
the driveline and resulting damage. If the gradient
is so steep that such an approach increases the
possibility of a tractor roll-over, select an alternate
crossing path.
11. OPERATING THE TRACTOR AND IMPLEMENT
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND
IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and
understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These
manuals must be read and explained to any operator who cannot read. Never allow someone to operate the
implement and tractor without complete operating instructions.
Before starting any operation, the operator must become familiar with the area to be worked in and any
obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special
attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.
OPS-U- 0015
Extreme care should be taken when operating near loose objects such
as gravel, rocks, wire, and other debris. Inspect the area before
mowing. Foreign objects should be removed from the site to prevent
machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by the
operator. Stop mowing immediately if blades strike a foreign object.
Repair all damage and make certain rotor or blade carrier is balanced
before resuming mowing. (SGM-05)
SX15 01/09
© 2009 Alamo Group Inc.
Operation Section 4-31
OPERATION
When operating the tractor and mower across
slopes and inclines, through ditches, and other
uneven terrain conditions, it is important to maintain
sufficient deck to ground clearance. Blade contact
with the ground may cause soil, rocks and other
debris to be thrown out from under the mower
resulting in possible injury and/or property damage.
Ground contact also produces a severe shock load
on the mower drive and to the mower blades
resulting in possible damage and premature wear.
OPS-R-0022
OPERATION
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the
operating parts of the mower head. These items could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could result
in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.
(SGM-06)
OPERATION
11.1 Foreign Debris Hazards
Before mowing, inspect the area to make sure
there are no foreign objects that the mower blades
could hit or become entangled with. Remove all
foreign objects and debris. If objects are too big to
remove, mark them clearly and be sure to prevent
the mower blades from contacting them.
If you hit a solid object or foreign debris, stop the
mower and tractor at once. Immediately idle the
engine speed and disengage the PTO. Wait for all
mower rotating motion to stop, then raise the
mower and move the tractor and implement off the
object. Inspect the area and remove, or mark the
location of the debris. Inspect the condition of the
mower and make any needed repairs immediately.
Make sure the blades are not damaged and the
carrier is balanced before resuming operation.
Always wear your seat belt securely fastened and
only operate the tractor and mower with the ROPS
in the raised position. If the tractor or mower hits a
tree stump, rock, or bump, a sudden movement
could throw you off of the seat and under the
tractor and/or mower. The seat belt is your best
protection from falling off the tractor and the ROPS
provides protection from being crushed during a
tractor roll-over. OPS-R-0023
11.2 Bystanders/Passersby Precautions
If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once,

OPERATION
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 100 YARDS UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable
condition;
-Mower sections or Wings are running close to and parallel to the ground without exposed
Blades;
-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)
11.3 Engaging the Power Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement
must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with
the implement in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to
the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you
hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the
implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027
Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the Cutting Blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown from
the Blades. (SRM-07)
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)

OPERATION
11.4 PTO RPM and Ground Speed
OPERATION
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.
Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower
at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or
the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground
speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut.
If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.
Ground speed is achieved by transmission gear selection and not by the engine operating speed. The
operator may be required to experiment with several gear range combinations to determine the best gear and
range which provides the most ideal performance from the mower and most efficient tractor operation. As the
severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to
maintain the proper operating PTO speed. OPS-R-0025
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)
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)
11.5 Operating the Mower
Only operate the mower from the tractor operator’s seat with the seatbelt securely fastened. The tractor must
be equipped with a ROPS in the raised position or a ROPS cab.
The mower is designed to cut vegetation up to 2”(50mm) in diameter. Sharp blades will produce a cleaner cut
and require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation
and maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving
pattern that provides the maximum pass length and minimizes turning.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the
same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining
the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and
be cut.
Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to
access areas to be cut, make sure there are no persons or other foreign debris behind the mower before
mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to
ensure tractor and mower control is maintained. OPS-R-0026_K
SX15 01/09
© 2009 Alamo Group Inc.
Operation Section 4-34
OPERATION
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)
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)
Follow these guidelines to reduce the risk of equipment and grass fires
while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accesible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.
Periodically shut down the Tractor and Mower and clean clippings and collected debris from
the mower deck. (SGM-12)
When you get to the end of a pass, slightly raise the
mower (2-4”) before turning. Never raise the mower
entirely while the blades are turning and NEVER
raise the mower wings while the blades are turning.
Mower is equipped with a constant velocity
driveline which can operate in conditions that
require frequent sharp turns. CV joints enable the
tractor PTO shaft and mower driveline to be angled
safely up to 80 degrees with no damage to the
mower or driveline. OPS-R-0027_C
SX15 01/09
© 2009 Alamo Group Inc.
Operation Section 4-35
OPERATION
Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
100 yards(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)
OPERATION
OPERATION
Stay alert and watch for trees, low hanging limbs,
power lines, and other overhead obstacles and solid
ground objects while you are operating. Use care
to avoid hitting these items. OPS-R-0028
When mowing across uneven areas such as road shoulders, ditch edges, and other uneven terrain, position
mower so that one support wheel is near the highest point to prevent blades from cutting into gravel or dirt
which can cause rapid blade wear and extremely severe shock loads on the drivetrain resulting in rapid wear
or damage to these components. Blades contacting the ground may cause objects to be thrown out from
under the mower deck. Always avoid operating the mower at a height or position which may cause the blades
to contact the ground. Cutting into the berm or edge of the ditch will cause abnormal and accelerated blade
wear and possible blade component failure. OPS-R-0029
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)

11.6 Shutting Down the Implement
To shut down attached mower head, first bring the
tractor to a complete stop. Decrease engine RPM
to idle then disengage cutterhead. The mower head
will come to a complete stop within a suitable
amount of time. Do not engage or disengage the
cutterheads at a high RPM unless there is an
emergency situation.
12. DISCONNECTING THE MOWER FROM THE TRACTOR
Before disconnecting the mower, the PTO must be disengaged and blade rotation at a complete stop. Move
the mower to a level storage location and lower the center section and both wings to the ground. If the mower
will be stored with the wings in the raised position, install both wing transport lock braces. If the mower is not
resting securely on the ground, block the mower up securely before attempting to disconnect it from the
tractor.
Use extreme care to keep feet and hands from under the mower and clear of any pinch points. OPS-R-0030
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)

OPERATION
OPERATION
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)
When disconnecting the mower the tractor should
be completely shut down and secured in position.
Relieve hydraulic pressure by moving the control
levers back and forth several times. Lower the
parking jack and raise the mower until the tongue
clevis is no longer resting on the tractor drawbar
and is supported solely by the jack. The jack
should be in a near vertical position with the ground
and can be adjusted by loosening the positioning
nut and moving the jack up to 15 degrees in each
direction.
Also make sure that the jack foot is
securely resting at ground level or securely
supported by a block before raising the mower.
Once the mower tongue is being supported entirely
by the jack, remove the hitch bolt, locknut, and
washers. Remove the hydraulic hoses from the
tractor and secure to the mower to prevent contact
with dirt.
After disconnecting the mower hitch, remove the
mower driveline from the tractor PTO shaft. Place
the driveline in its storage bracket to prevent it from
contacting mud or dirt which can contaminate the
universal joint bearings and shorten the life of the
driveline.
After the driveline has been removed from the
tractor, place the PTO master shield back in the
operating position. OPS-R-0031

13. MOWER STORAGE
It is recommended that the mower be stored with the center section and both wings fully lowered to ground
level. If the mower is stored with the wings in the raised position, select a level area and install wing transport
braces to prevent the wings from falling BEFORE disconnecting the mower hitch from the tractor.
Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance
and to help ensure years of dependable service. The following are suggested storage procedures:
•
•
•
•
•
•
It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid mower and/or
tractor damage. If the mower sits outside for an extended period of time or is exposed to rain and/or humid
air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion. If
the mower has been exposed to such conditions, at the start of each mowing season, and any time it is
suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Seasonal
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
14. 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

mower moving parts to come to a complete stop.
Once all mower parts are completely stopped, raise
the mower to transport height. NOTE: When
raising the mower, maintain at least 1” clearance
between the driveline and mower deck. If additional
mower deck height is needed for safe transport,
disconnect the driveline from the tractor and secure
its end to the mower deck. The mower can then be
raised to the maximum lift height.. OPS-R-0033
If the tractor’s hydraulic pump is not independent of
the tractor PTO, or if the tractor PTO has to be run

14.1 Tire and Wheels
Laminated Sectional Tires are designed for conditions where puncture proof performance is required and
the mower will not be transported for long distances on roadways. Transport speed for laminated tires should
not exceed 20 MPH. Excessive speed can cause damage to the machine and tire sections. Laminated tires
must be installed such that the rubber segments lay with the ground.
OPERATION
Foam Filled used Airplane Tires are ideal for conditions where a puncture proof tire is needed and the
mower is frequently transported between locations.
Pneumatic Tires Implement tires are ideal for frequent long distance towing, however, they are not puncture
proof and are not recommended for mowing brushy areas or other conditions that could damage the tires.
Check side wall of tire for proper inflation pressure. DO NOT over-inflate. OPS-R-0035
14.2 Transporting on Public Roadways
Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor
must be equipped with all required safety warning features including a SMV emblem and flashing warning
lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for
automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.
Check your side view mirrors frequently and remember that vehicles will approach quickly because of the
tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than
the tractor tire width and/or extends beyond your lane of the road.
Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a
public road. OPS-U- 0019
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

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.
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 POSSIBLE
SERIOUS INJURY FROM THROWN BLADES. (SGM-10)
Inspect Blades daily for abnormal wear. If Blades have a notch worn into the leading edge at
the lower b end more than a 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!
BLADE SHARPENING
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in
Mnt-R-0008. Always sharpen blades by grinding. DO NOT heat and pound out edge. Do not sharpen blade to
a razor edge. Do not sharpen blade to a razor edge, but leave a 1/16" blunt edge. Do not sharpen back side of
blade.
IMPORTANT: 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.
Never work under equipment supported by a hydraulic device because it may drop if the
control is actuated (even with the engine stopped) or in the event of hose failure, etc. Always
use a secure support for equipment which must be serviced while in the raised position.

MAINTENANCE
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.
MAINTENANCE
MAINTENANCE
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 POSSIBLE
SERIOUS INJURY FROM THROWN BLADES. (SGM-10)
NOTE: Replace Blades in pairs after no more than 1/2” notch wear!
BLADE REMOVAL
To remove blades for sharpening or replacement,
remove the cover plate on deck of cutter near gear
box. Remove lock nut from blade bolt. NOTE:
Inspect lock nut after removal and replace if threads
are damaged. Always replace nut when replacing
blade bolt. When installing blades be sure and
check blade bolt pivot diameter for wear. Replace
bolt if worn more than 1/4 inch at any point. See
Figure Mnt-R-0014. Install blade bolts with partially
worn side of bolt either toward or away from center.
Tighten locknut to 300 ft. lbs.
Avoid personal injury. Blade and/or blade carrier removal should be done only with the
tractor engine shut off, key removed, in neutral, parking brake on, PTO disengaged, and the
cutter blocked in the raised position.
BLADE CARRIER REMOVAL
Remove cotter pin and loosen slotted nut on gear box shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable two-jaw gear puller to pull carrier off tapered gear box shaft. If gear puller is
not available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite
end of bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process.

MAINTENANCE
BLADE CARRIER INSPECTION
Failure to replace a worn blade carrier bushing as described above may lead to catastrophic
failure of the blade, blade bolt, and/or blade bolt nut resulting in the ejection of the broken
parts out from under the mower at tremendous speed and force which could result in serious
bodily injury or death.

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 so that bottom of bushing is flush
with bottom of blade bar. Use low hydrogen rod to weld bushing in place.
MAINTENANCE
BLADE CARRIER INSTALLATION
Clean the spines on both the blade carrier and output shaft. Position carrier on the gearbox output shaft and
install flatwasher and 1" hex nut. Tighten nut holding blade carrier to minimum 450 ft. pounds, strike the carrier
on 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. pounds. Install and spread cotter pin.
MAINTENANCE
NOTE: After a few hours of operation always recheck blade carrier retaining nut torque.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from
falling.
SLIP CLUTCH
A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and protect the
driveline.
After the first hour of operation, the slip clutch should be checked for overheating. After this first check, the slip
clutch should be checked weekly or anytime there is overheating. To adjust the slip clutch, tighten the spring
bolts to 1-5/16” length. Any increase or decrease in this tightness will change the torque rating and could cause
premature failure.
The slip clutch should be checked periodically and adjusted to compensate for wear. The lining plates are 1/8"
thick when new. Replace after 1/16" wear. If the mower has been idle for an extended period of time, or in wet
weather, before operating check to be sure the friction lining plates are not rusted/corroded together. Should
this occur refer to the procedure described in the "Seasonal Clutch Maintenance" section on the next page.
There are two friction lining plates in the slip clutch. These should be checked weekly for oil or grease, wear,
and moisture which could cause corrosion on the drive plates.

Coil Spring Slip Clutch
SEASONAL CLUTCH MAINTENANCE
It is important that the clutches slip when an obstacle or load heavier than the clutch setting is encountered.
Therefore, if the machine sits outside longer than 30 days and is exposed to rain and/or humid air it is
important to make sure that the clutch lining plates are not rusted/corroded together. Before using the cutter
use the following procedure to make sure the clutch will slip and give the overload protection required.
1.
2.
3.
4.
5.
Loosen nuts (Figure Mnt-R-0353) on springs until the springs are free, yet remain secure on bolts.
Attach cutter to tractor and start the tractor. Set the engine speed at 1200 RPM.
Mark outer plates as shown in Figure Mnt-R-0353
Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates
should break loose (check the mark).
Turn tractor off. Tighten the nuts on the coil spring clutch to their original position of 1-5/16”
compressed spring length.

MAINTENANCE
HYDRAULIC HOSES
MAINTENANCE
Replace pinched and broken Hydraulic Hoses at once. Tighten any Hydraulic Fitting with fluid leaking from it. If
fluid still leaks, loosen the fitting, apply a pipe thread compound to the threads and tighten. Care must be
exercised when tightening Hydraulic Fittings. Too much tightening can cause the fittings to crack and require
replacement fittings.
Although a small amount of oil will be present from bleeding at all Hydraulic Fittings, significant amounts of oil
leaking around the Breather Plug on the Cylinder indicates that the seal in the Cylinder is worn out. Replace
the seals in the Cylinder immediately before the Cylinder is damaged or too much hydraulic fluid is lost.
SKID SHOES
Skid shoes are made of carbon steel to reduce wear and increase service life. Premature wear can be caused
by the mower Center or Wing sections being set too low which allows the Wing Skid Shoes to drag on the
ground. Dragging the Skid Shoes on the ground or running the Skid Shoes into solid objects can contribute to
early frame failure on the mower. Replace worn Skid Shoes as required.
MOWER STORAGE
Your rotary cutter represents an investment from which you should get the greatest possible benefit. Therefore,
when the season is over, the cutter should be thoroughly checked and prepared for storage so that a minimum
amount of work will be required to put it back into operation for the next season. The following are suggested
storage procedures:
1.
2.
3.
4.
5.
6.
Thoroughly clean the cutter.
Lubricate the cutter as covered in Maintenance Section.
Tighten all bolts and pins to the recommended torque.
Check the cutter for worn or damaged parts. Make replacements immediately.
Store the cutter in a clean, dry place with the cutter housing resting on blocks.
Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the
cutter.
