SAFETY
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.
The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this
manual and on decals which are attached to the equipment. The Safety Alert Symbol means:
“ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal Word
are intended to warn the owner/operator of impending hazards and the degree of possible injury
faced when operating this equipment.
Practice all usual and customary safe working precautions and above all---remember safety is
up to YOU. Only YOU can prevent serious injury or death from unsafe practices.
Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR
VERY SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH
OR SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR
INJURY.
Identifies special instructions or procedures that, if not strictly observed, could result in
damage to, or destruction of the machine, attachments or the environment.
NOTE: Identifies points of particular interest for more efficient and convenient operation or
repair.(SG-1)
READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or
death may occur unless care is taken to follow the warnings and instructions stated in the
Safety Messages. Always use good common sense to avoid hazards. (SG-2)

SAFETY
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
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)
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 use drugs or alcohol immediately before or while operating the
Tractor and Implement.
alertness and coordination and therefore affect the operator’s ability to
operate the equipment safely. Before operating the Tractor or
Drugs and alcohol will affect an operator’s
Implement, an operator on prescription or over-the-counter medication
must consult a medical professional regarding any side effects of the
medication that would hinder their ability to operate the Equipment safely.
NEVER knowingly allow anyone to operate this equipment when their
alertness or coordination is impaired. Serious injury or death to the
operator or others could result if the operator is under the influence of
drugs or alcohol. (SG-27)
Prolonged operation may cause operator boredom and fatigue affecting safe operation.
Take scheduled work breaks to help prevent these potentially impaired operating
conditions. Never operate the Implement and Tractor in a fatigued or bored mental state
which impairs proper and safe operation. (SG-32)
Use extreme caution when getting onto the Implement to perform repairs, maintenance and
when removing accumulated material. Only stand on solid flat surfaces to ensure good
footing. Use a ladder or raised stand to access high spots which cannot be reached from
ground level. Slipping and falling can cause serious injury or death. (SG-33)
Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and
hose connections. Relieve hydraulic pressure before performing maintenance or repairs.
Use gloves and eye protection when servicing hot components. Contact with a hot surface
or fluid can cause serious injury from burns or scalding. (SG-34)
DO NOT operate this Implement on a Tractor that is not properly maintained. Should a
mechanical or Tractor control failure occur while operating, immediately shut down the
Tractor and perform repairs before resuming operation. Serious injury and possible death
could occur from not maintaining this Implement and Tractor in good operating condition.
(SG-36)
Avoid contact with hot surfaces of the engine or muffler. Use gloves and eye protection
when servicing hot components. Contact with a hot surface or fluid can cause serious injury
from burns or scalding. (SG-38)
The rotating parts of this machine continue to rotate even after the Tractor has been turned

clothing with the rotating elements can result in serious injury or even death. Stay clear of
all rotating elements at all times. (SSP-3)
Connecting & Disconnecting Implement Safety Instructions & Practices
Each Rear Wheel must have a minimum of 1500 pound contact with the
surface to prevent lateral instability and possible tip-over which could
result in serious bodily injury or even death. Widen the wheel tread and
add weights if needed. Refer to the mounting instructions or call Customer Service if you
need assistance with Couterweight Procedure. (SBM-11)
Do Not attempt to raise or lower the boom or mower head unless the Implement is securely
attached to the Tractor. The Implement could tip over and cause equipment damage and
possible serious injury or death. Do Not use the boom controls to assist in installing the
implement on the tractor. Raise or Lower the boom and mower head only while seated in the Tractor
operator’s seat with the seat belt securely fastened. Inadvertent contact with the boom controls could allow a

SAFETY
Equipment Operation Safety Instructions and Practices
Never leave the Tractor and Implement unattended while the Implement is in the lifted posi-
tion. 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)
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)
Use extreme caution when raising the Mower head. Stop the Blades from turning when the
Mower Head is raised and passersby are within 100 yards. Raising the Mower head
exposes the Cutting Blades which creates a potentially serious hazard and can cause
serious injury by objects thrown from the Blades or by contact with the Blades. (SBM-2)
Never Leave the mower unattended while the head is in the raised
position. The mower could fall causing serious injury to anyone who
might inadvertently be under the mower. (SBM-4)
Always keep a careful lookout and use extreme care when working
around overhead obstructions. Never allow the Mower head or boom
within 10 feet of any power line. When working close to overhead
power lines consult your electric company for a safe code of operation.
(SBM-7)
The center of Gravity of Tractors equipped with a Rear-Mounted Boom
Mower is shifted to the rear and removes weight from the front wheels.
Add front ballast until at least 20% of the tractors weight is on the front
wheels to prevent rearing up, loss of steering control, and possibly
injury. (SBM-10)
The Mower shaft speed must not - UNDER ANY CIRCUMSTANCES - exceed 1800 RPM.
(SBM-15)
Use extreme care and Safety Awareness when using the boom mower head to mulch loose
brush or wood that has fallen on the ground from overhead trimming. DO NOT mulch this
debris if bystanders, vehicles, livestock or buildings are within 300 feet of the mower. This
cut debris can be thrown at great velocities and could result in serious injury or even death. (SBM-17)
Do not back up this implement when the boom or mower head is extended. Backing could
damage the machine or its components. (SBM-19)

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 accessible
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.
-Do Not attempt to mow or place the mower head close to
burning debris.
-Never allow clippings or debris to collect near drivelines,
gearboxes or hydrualic componts such as valves, tanks,
pumps and motors. Periodically shut down the Tractor and
Mower and clean clippings and collected debris from the
mower deck. (SBM-20)
Do not operate Mower if excessive vibration exists.
Shut down PTO and the Tractor
engine. Inspect the Mower to determine the source of the vibration. If Mower blades are
missing or damaged replace them immediately.
Do not operate the mower until the
blades have been replaced and the Mower operates smoothly. Operating the Mower with excessive vibration
can result in component failure and broken objects to be thrown outward at very high velocities. To reduce the
possibility of property damage, serious injury, or even death, never allow the Mower to be operated with
blades missing. (SFL-4)

SAFETY
Flail Mowers are capable under adverse conditions of throwingobjects
for great distances (100 yards or more) and causing seriousinjury 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,
workablecondition;
-Mower sections
or Wings are running close to and parallel to the ground
withoutexposed Blades;
-Passerby are outside the existing thrown-object zone;-All areas have been thoroughly
inspected and all foreign material such as rocks, cans, glass, and general debris has
been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could
bestruck by the blades, the area should be: inspected and large debris removed, mowed
atan intermediate height, inspected, closely with any remaining debris being removed,
andmowed 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,
eliminatestreaking, and make the final cut more uniform.) (SFL-6)
Operate this Equipment only with a Tractor equipped with an approved roll-
over-protective system (ROPS). Always wear seat belts. Serious injury or
even death could result from falling off the tractor--particularly during a turnover
when the operator could be pinned under the ROPS. (SG-7)
BEFORE leaving the tractor seat, always engage the brake and/or set
the tractor transmission in parking gear, disengage the PTO, stop the
engine, remove the key, and wait for all moving parts to stop. Place the
tractor shift lever into a low range or parking gear to prevent the tractor
from rolling. Never dismount a Tractor that is moving or while the engine
is running. Operate the Tractor controls from the tractor seat only. (SG-9)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
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
Do not mount the Tractor while the tractor is moving. Mount the Tractor
only when the Tractor and all moving parts are completely stopped. (SG-12)
Start tractor only when properly seated in the Tractor seat. Starting a
tractor in gear can result in injury or death. Read the Tractor operators
manual for proper starting instructions. (SG-13)
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and
fuel are explosive and their presence could present a hazard. Do not
check for leaks with your hand! High-pressure oil streams from breaks in
the line could penetrate the skin and cause tissue damage including
gangrene. To check for a hose leak, SHUT the unit ENGINE OFF and
remove all hydraulic pressure. Wear oil impenetrable gloves, safety
glasses and use Cardboard to check for evidence of oil leaks. If you
suspect a leak, REMOVE the HOSE and have it tested at a Dealer. If oil
does penetrate the skin, have the injury treated immediately by a
physician knowledgeable and skilled in this procedure. (SG-15)
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death. (SG-26)
Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat
with the seat belt securely fastened around you. Inadvertent movement of the Tractor or
Implement may cause serious injury or death. (SG-29)
In case of mechanical difficulty during operation, place the transmission in the park
position, set the parking brake, shut down all power, including the PTO and the engine and
remove the key. Wait until all rotating motion has stopped before dismounting. (SG-39)
