WARNING
FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT
IN SERIOUS INJURY OR DEATH.
• Read this manual completely as well as other manuals that came with your mower.
• ALWAYS FOLLOW OSHA APPROVED OPERATION.
• DO NOT operate on steep slopes.
• Under no circumstances should the machine be operated on slopes greater than 20
degrees. ALWAYS FOLLOW OSHA APPROVED OPERATION.
• Stay two cut widths away from slopes, drop offs, ditches and retaining walls.
• DO NOT back down a slope or ramp.
• DO NOT mow on wet grass. Wet grass reduces traction and steering control.
• Keep all shields in place, especially the grass discharge chute.
• Before performing any maintenance or service, stop the machine and remove the
spark plug wire and ignition key.
• If a mechanism becomes clogged, stop the engine before cleaning.
• Keep hands, feet and clothing away from power-driven parts.
• Keep others off the mower (only one person at a time)
REMEMBER - YOUR MOWER IS ONLY AS SAFE AS THE OPERATOR!
HAZARD CONTROL AND ACCIDENT PREVENTION ARE DEPENDENT UPON THE AWARENESS,
CONCERN, PRUDENCE, AND PROPER TRAINING OF THE PERSONNEL INVOLVED IN THE
OPERATION, TRANSPORT, MAINTENANCE, AND STORAGE OF THE EQUIPMENT.

Section 2
3. DO NOT allow children to ride or play on the
machine, it is not a toy.
4. Clear the area to be mowed of objects that could be
picked up and thrown by the cutter blades.
5. DO NOT carry passengers.
6. DO NOT operate the machine under the influence of
alcohol or drugs.
7. If the operator(s) or mechanic(s) cannot read
English, it is the owner's responsibility to explain this
material to them.
8. DO NOT wear loose fitting clothing. Loose clothing,
jewelry or long hair could get tangled in moving
parts. Do not operate the machine wearing shorts;
always wear adequate protective clothing including
long pants. Wearing safety glasses, safety shoes and
a helmet is advisable and is required by some local
ordinances and insurance regulations.
WARNING
Always wear hearing protection. Operating this
machine over prolonged periods of time can
cause loss of hearing.
9. Keep the machine and attachments in good
operating condition. Keep all shields and safety
devices in place. If a shield, safety device or decal
is defective or damaged, repair or replace it before
operating the machine.
WARNING
This machine is equipped with an interlock system
intended to protect the operator and others from
injury. This is accomplished by preventing the
engine from starting unless the deck drive is
disengaged, the parking brake is engaged, the
steering control levers are in the neutral position
and the operator is in the operator position.
The interlock system shuts off the engine if the
operator leaves the operator platform with the
steering control levers not in the neutral position
and/or the cutter blades engaged and the parking
brake not engaged.
10. Be sure the interlock switches are functioning
correctly.
11. Fuel is flammable; handle it with care. Fill the fuel
tank outdoors. Never fill it indoors. Use a funnel or
spout to prevent spillage. Clean up any spillage
before starting the engine.
12. DO NOT add fuel to a running or hot engine. Allow
the engine to cool for several minutes before adding
fuel. Never fuel indoors or inside enclosed trailers.
13. Keep flammable objects (cigarettes, matches, etc.),
open flames and sparks away from the fuel tank and
fuel container. Use only approved containers.
14. Equipment must comply with the latest requirements
per SAE J137 and/or ANSI/ASAE S279 when driven
on public roads.
15. Do not operate without the side discharge chute
installed and in the down position or with an optional
grass catcher or mulch plate completely installed.
16. Check the blade mounting bolts at frequent intervals
for proper tightness.
17. Make sure all hydraulic fluid connections are tight
and all hydraulic hoses and lines are in good
condition before starting the machine.
2.4 OPERATION CONSIDERATIONS
1. Know the function of all controls and how to stop
quickly.
WARNING
DO NOT operate on steep slopes. Under no
circumstances should the machine be operated
on slopes greater than 20 degrees. See Figure
2-1 to determine approximate slope of area to
be mowed. ALWAYS FOLLOW OSHA APPROVED
OPERATION.
2. Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tipping or loss
of control. Be especially cautious when changing
directions on slopes.
3. Stay two cut widths away from slopes, drop offs,
ditches and retaining walls.
4. To prevent tipping or loss of control, start and stop
smoothly, avoid unnecessary turns and travel at
reduced speed.
5. Immediately apply the parking brake if you lose
steering control while operating. Inspect the machine
and correct the problem before continuing to operate.

5

Section 2
6. When using any attachment, never direct the
discharge of material toward bystanders or allow
anyone near the machine while in operation.
7. Start the engine with the operator in the operating
position, cutter blades are disengaged, parking
brake is engaged, and the neutral lever is in neutral.
8. If the mower discharge ever plugs, shut off the
engine, remove the ignition key, and wait for all
movement to stop before removing the obstruction.
WARNING
DO NOT use your hand to dislodge the clogged
discharge chute. Use a stick or other device to
remove clogged material after the engine has
stopped running and the blades have stopped
turning.
9. Be alert for holes, rocks, roots and other hidden
hazards in the terrain. Keep away from any drop
offs. Beware of overhead obstructions (low limbs,
etc.), underground obstacles (sprinklers, pipes, tree
roots, etc.). Cautiously enter a new area. Be alert for
hidden hazards.
10. Disengage power to cutter deck before backing up.
Do not mow in reverse unless absolutely necessary
and then only after observation of the entire area
behind the mower. If you must mow in reverse,
maintain a constant lookout to the rear of the
machine and mow slowly.
11. DO NOT turn sharply. Use care when backing up.
12. Disengage power to cutter deck before crossing
roads, walks or gravel drives.
13. Mow only in daylight or good artificial light.
14. NEVER raise the deck with the blades engaged.
15. Take all possible precautions when leaving the
machine unattended, such as disengaging the
mower, stopping the engine, and removing the key.
16. Disengage power to the attachments when
transporting or when not in use.
17. The machine and attachments should be stopped
and inspected for damage after striking a foreign
object, and damage should be repaired before
restarting and operating the machine.

or truck. Ensure the trailer or truck has all of the
necessary lighting and markings as required by
laws, codes, and ordinances. Secure a trailer with a
safety chain.
20. Be cautious when loading and unloading onto
trailers or trucks. Use only a full width ramp. Always
back on and drive off a trailer.

lock lever is in neutral lock, the engine is off with the
key removed, the parking brake is engaged and the
wheels have been blocked.

so. If the engine is running, keep hands, feet, and
clothing away from moving parts.
2. Place the control levers in the neutral position,
engage the parking brake, stop engine and remove
key or disconnect spark plug wire to prevent
accidental starting of the engine when servicing or
adjusting the machine. Wait for all movement to stop
before adjusting, cleaning or repairing.
3. Remove spark plug wire before making any repairs.
4. Keep all nuts, bolts and screws tight, to ensure the
machine is in safe working condition. Check blade
mounting bolts frequently to be sure they are tight.

6. To reduce fire hazard, keep the cutting units, drives,
muffler and engine free of grass, leaves, excessive
grease, oil and dirt.
7. Park the machine on level ground.
8. NEVER allow untrained personnel to service the
machine.
9. Use care when checking blades. Use a Blade Buddy,
wrap the blade(s) or wear gloves and USE CAUTION
when servicing blades. Only replace blades. NEVER
straighten or weld blades.
10. Keep all parts in good working condition. Replace all
worn or damaged decals.
11. Use jack stands to support components when
required.
