DANGER!
WARNING!
CAUTION!PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PER-
Do not operate this Equipment with hydraulic oil leaking. Oil is
expensive and its presence could present a hazard. Do not check for
leaks with your hand! Use a piece of heavy paper or cardboard. Highpressure oil streams from breaks in the line could penetrate the skin
and cause tissue damage including gangrene. If oil does penetrate the
skin, have the injury treated immediately by a physician knowledgeable and skilled in this procedure. (SG-15)
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 thrown
by the equipment. (SG-16)
MANENT HEARING LOSS! Tractors with or without an Implement
attached can often be noisy enough to cause permanent hearing
loss. We recommend that you always wear hearing protection if
the noise in the Operator’s position exceeds 80db. Noise over
85db over an extended period of time will cause severe hearing
loss. Noise over 90db adjacent to the Operator over an extended
period of time will cause permanent or total hearing loss. Note:
Hearing loss from loud noise [from tractors, chain saws, radios,
and other such sources close to the ear] is cumulative over a
lifetime without hope of natural recovery.(SG-I7)
WARNING!Transport only at safe speeds. Serious accidents and injuries can re-
sult from operating this equipment at unsafe speeds. Understand the
Tractor and Implement and how it handles before transporting on streets
and highways. Make sure the Tractor steering and brakes are in good
condition and operate properly.
Before transporting the Tractor and Implement, determine the safe
transport speeds for you and the equipment. Make sure you abide by
the following rules:
Test the tractor at a slow speed and increase the speed slowly.
1.
Apply the Brakes smoothly to determine the stopping
characteristics of the Tractor and Implement.
As you increase the speed of the Tractor the stopping distance
increases. Determine the maximum safe transport speed for
you and this Equipment.
Test the equipment at a slow speed in turns. Increase the speed
2.
through the turn only after you determine that it is safe to operate
at a higher speed. Use extreme care and reduce your speed when
turning sharply to prevent the tractor and implement from turning
over. Determine the maximum safe turning speed for you and this
equipment before operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds that you
3.
have determined are safe and which allow you to properly control the
equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes. When operating
down a hill or on wet or rain slick roads, the braking distance increases: use extreme care and reduce your
speed. When operating in traffic always use the Tractor’s flashing warning lights and reduce your speed. Be
aware of traffic around you andwatch out for the other guy. (SG-19)

Never attempt to lubricate, adjust, or remove material from the
Implement while it is in motion or while tractor engine is running.
Make sure the tractor engine is off before working on the Implement.
(SG-20)
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)
Always read carefully and comply fully with the manufacturers instructions when handling oil, solvents, cleansers, and any other chemical
agent. (SG-22)
Never run the tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your
health.
(SG-23)
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)
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)
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)
DANGER!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)
WARNING!
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 in front
and to the sides of the tractor and mower. Make sure that you can clearly see and identify
passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and
foreign objects. If you are unable to clearly see this type of items discontinue mowing.(SGM-
1)
DANGER!
There are obvious and hidden potential hazards in the operation of
this Mower. REMEMBER! This machine is often operated in heavy
brush and in heavy weeds. The Blades of this Mower can throw
objects if shields are not properly installed and maintained. Serious
injury or even death may occur unless care is taken to insure the
safety of the operator, bystanders, or passersby in the area. Do not
operate this machine with anyone in the immediate area. Stop
mowing if anyone is within 100 yards of mower. (SGM-2)
DANGER!All Safety Shields, Guards and Safety devices including
(but not limited to) - the Deflectors, Chain Guards, Steel
Guards, Gearbox Shields, Hydraulic Tank Shields, and
Retractable Door Shields should be used and maintained in good working condition. All safety devices
should be inspected carefully at least daily for missing
or broken components. Missing, broken, or worn items
must be replaced at once to reduce the possibility of
injury or death from thrown objects, entanglement, or
blade contact. (SGM-3)
SAFETY
DANGER!
WARNING!
WARNING!
WARNING!
The rotating parts of this machine have been designed and tested for rugged use. However,
they could fail upon impact with heavy, solid objects such as steel guard rails and concrete
abutments. Such impact could cause the broken objects to be thrown outward at very high
velocities. To reduce the possibility of property damage, serious injury, or even death, never
allow the cutting blades to contact such obstacles. (SGM-4)
Extreme care should be taken when operating near loose objects
such as gravel, rocks, wire, and other debris. Inspect the area before
mowing. Foreign objects should be removed from the site to prevent
machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by
the operator. Stop mowing immediately if blades strike a foreign
object. Repair all damage and make certain rotor or blade carrier is
balanced before resuming mowing. (SGM-5)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating
parts of the mower head. These items could then swing outside the housing at greater velocities
than the blades. Such a situation is extremely hazardous and could result in serious injury or even
death. Inspect the cutting area for such objects before mowing. Remove any like object from the
site. Never allow the cutting blades to contact such items. (SGM-6)
Mow at the speed that you can safely operate and control the tractor and mower. Safe mowing
speed depends on terrain condition and grass type, density, and height of cut. Normal ground
speed range is from 0 to 5 mph. Use slow mowing speeds when operating on or near steep slopes,
ditches, drop-offs, overhead obstructions, power lines, or when debris and foreign objects are to
be avoided. (SGM-7)
Avoid mowing in reverse direction when possible. Check to make sure there are no persons are
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 in
the reverse direction that you have not inspected and removed debris or foreign material. (SGM-
8)
Do not put hands or feet under mower decks. Blade Contact can result
serious injury or even death. (SGM-9)

WARNING!
SAFETY
DANGER!
Do not mow with two machines in the same area except with Cab tractors with the windows closed.
(SGM-11)
Rotary Mowers are capable under adverse conditions
of throwing objects for great distances (100 yards
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;
-Passersby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material
such as rocks, cans, glass, and general debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could be struck by
the blades, the area should be: inspected and large debris removed, mowed at an intermediate
height, inspected, closely with any remaining debris being removed, and mowed again at
desired final height. (This will also reduce power requiredto mow, reduce wear and tear on
the Mower drivetrain, spread cut material better, eliminate streaking, and make the final cut
more uniform.)
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-7)
Never leave Tractor and Implemented 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 AFrame. Lower the implement carefully to the ground. Do not put hands or feet under lifted
components. (S3PT-1)
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-2)
Safety Section 1-8LJ60/72 02-02
SAFETY
DANGER!
DANGER!
WARNING!
There are obvious and hidden potential hazards in the operation of this Implement as in all
power-driven or pulled equipment. REMEMBER! This machine is often operated in rough
terrain conditions that include tall grass, weeds, gullies, holes, slopes, hidden obstructions and
the like. Serious injury or even death may occur unless care is taken to assure the safety of the
operator and bystanders in the area. Do not operate this machine with anyone in the immediate
area. (S3PT-7)
Make sure the PTO shield is installed when using PTO-driven equipment.
Always replace the PTO shield if it is damaged or missing. (S3PT-8)
Relieve hydraulic pressure prior to doing any maintenance or repair work
on the Implement. Place the Implement on the ground or securely
blocked up, disengage the PTO, and turn off the tractor engine. Push
and pull the Remote Cylinder lever in and out several times prior to
starting any maintenance or repair work. (S3PT-9)
SAFETY
WARNING!
DANGER!
DANGER!
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!”
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)
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)
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.
Do not mow with two machines in the same area except with Cab tractors with the windows closed.
(SGM-11)
Replace bent or broken blade with new blades. NEVER ATTEMPT TO STRAIGHTEN OR WELD
ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE BLADE
WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM THROWN BLADES.
(SGM-10)
(SGM-12)
In addition to the design and configuration of this Implement, including Safety Signs and Safety Equipment,
hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper
training of personnel involved in the operation, transport, maintenance, and storage of the machine. Refer also
to Safety Messages and operation instruction in each of the appropriate sections of the Tractor and Equipment
Manuals. Pay close attention to the Safety Signs affixed to the Tractor and Equipment. (SG-18)
