IMPORTANT SAFETY PRECAUTIONS
This symbol is used to call attention to safe-
ty precautions that should be followed by
the operator to avoid accidents. When you
see this symbol, carefully read the message
that follows and heed its advice. Failure to
comply with safety precautions could result
in serious bodily injury.
n addition to the design and configuration of equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and proper training of personnel in the operation,
transport, maintenance and storage of equipment. Lack of attention to safety can result in accident, person-
al injury, reduction of efficiency and worst of all—loss of life. Watch for safety hazards and correct deficien-
cies promptly. Use the following safety precautions as a general guide to safe operations when using this
machine. Additional safety precautions are used throughout this manual for specific operating and mainte-
nance procedures. Read this manual and review the safety precautions often until you know the limitations.
ACCIDENT PATTERNS TO AVOID
1. CONTACT W TH THE ROTAT NG BLADE - This accident usually happens when the operator is clear-
ing the discharge chute of grass, (especially when the grass is wet), or when the operator adjusts the
machine without turning it off and waiting for the blades to completely stop.
2. PROPELLED OBJECTS - Sticks, rocks, wires, and other objects can be propelled out through the dis-
charge chute or from under the mower housing. Bystanders are particularly vulnerable.
3. GRASS D SCHARGE CHUTE - The mower shall not be operated without the grass discharge chute
in its lowered position.
4. OVERTURN NG - This happens when riding mowers are used on steep slopes, embankments or hills.
The operator in these cases can come in contact with blades or sustain injuries during a fall.
5.
MOWER RUNN NG OVER THE V CT M - This usually happens when a riding mower is driven in reverse.
The accident victims are most often young children whom, unseen by the operator of the mower, were
in the area being mowed.
WE SHARE YOUR DESIRE TO PROTECT YOURSELF, YOUR FAMILY, YOUR FRIENDS AND YOUR
NEIGHBORS FROM ACCIDENTAL INJURY. OBSERVING AND ENFORCING THE FOLLOWING GUIDE
LINES WILL HELP TO INSURE THE SAFETY OF EVERYONE.
SAFETY INSTRUCTIONS AND RECOMMENDATIONS
1. PEOPLE WHO OPERATE, SERV CE, OR ARE OTHERW SE ASSOC ATED with the Zero Turning
Riding Mower should be trained in its proper use and warned of its dangers. Before operating, adjusting,
or servicing the Zero Turning Riding Mower they should read and understand this entire manual and the
engine manual.
2. AVO D CONTACT W TH MOV NG PARTS. Keep hands and feet from under mowing deck and away
from blades at all times. Turn engine (motor) off if you must unclog the chute.
3. AVO D H LLS AND SLOPES. Use EXTREME caution when mowing and/or turning on slopes as loss of traction
and/or tip-over could occur. Drive slower on slopes. DO NOT mow slopes greater than 15 degrees. Watch for
ditches, holes, rocks, dips and rises, which change the operating angle. Keep away from drop-offs and steep
banks. Avoid sudden starts when mowing uphill - mower may tip backwards. Loss of traction may occur going
downhill - weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking. DO NOT
mow slopes when grass is wet - slippery conditions affect steering and reduce traction and braking. The operator
is responsible for safe operation on slopes.
4. D SENGAGE POWER TO MOWER BEFORE BACK NG UP. Do not mow in reverse unless absolutely
necessary and then only after turning around and observing the entire area behind the mower. Go slowly.
Most “running over victim” accidents occur in reverse.
5. BEG NN NG OPERATORS SHOULD LEARN HOW TO STEER the Zero Turning Riding Mower before
attempting to mow. Start with slow engine speed and drive without the blades engaged in open area until
comfortable with the machine.
5

SAFETY CONTINUED
6. KNOW HOW TO STOP QU CKLY. Know the location and operation of every control, especially how to brake and
how to disengage the mower blades.
7. DO NOT MOVE THE CONTROL LEVERS from forward position to reverse position rapidly. The speed
and/or direction of travel is affected instantly by movement of the Control Levers.
8. DO NOT ALLOW CH LDREN TO OPERATE MOWER. Do not allow others who have not had instruc-
tions to operate mower. Do not operate the mower when children or others are in the area.
9. ALWAYS TURN ENG NE OFF AND REMOVE KEY before leaving mower to prevent children and
inexperienced operators from starting the engine. Never leave the mower unattended with engine run-
ning. Always wait for all moving parts and all sounds to stop before leaving operator’s seat. Always set
the parking brake on an unattended mower.
10. WEAR STURDY, ROUGH-SOLED WORK SHOES AND CLOSE-F TT NG TROUSERS AND SH RTS.
Never operate mower in bare feet, sandals or sneakers.
11. WEAR PERSONAL PROTECT VE EQU PMENT such as, but not limitied to, protection for eyes, ears, feet, hands
and head when operating or repairing equipment. Do not wear loose clothing or jewelry that may catch on equip-
ment moving parts.
12. NEVER CARRY PASSENGERS.
13. KNOW THE AREA YOU ARE TO MOW. Watch for hidden dangers such as rocks, roots, sticks, holes,
bumps, and drop-offs, etc. Before mowing, pick up all debris in area to be mowed. Sharp and hard
objects can be propelled at a high speed and can act like shrapnel. Walk through tall grass BEFORE
MOW NG to make sure there are no hidden dangers. Mow higher than desired in tall grass to expose
any hidden objects and/or obstacles, clean the area, and then mow to the desired height.
14. BE SURE THE AREA S CLEAR of other people before mowing. Stop machine if anyone enters the area.
15. NEVER REFUEL A MOWER NDOORS. Allow the engine time to cool before refueling. Unseen vapors may be
ignited by a spark. Always clean up spilled gasoline. Never run the engine indoors in a garage
or any other closed building. Allow engine to cool before storing in any enclosure. The engine exhaust
and gasoline fumes are dangerous.
16. NEVER REMOVE THE FUEL CAP or add gasoline to a running or hot engine or an
engine that has not been allowed to cool for several minutes after running. Always make sure the gas
cap is in place.
17. DO NOT SMOKE AROUND THE MOWER or the gasoline storage container. Gasoline fumes can easi-
ly ignite.
18. KEEP GASOL NE N A WELL-VENT LATED AREA away from your living quarters and in tightly
capped safety cans. Never store mower with gasoline in the tank inside a building where fumes may
reach open flame or spark.
19. D SENGAGE BLADES, STOP ENG NE, ENGAGE PARK NG BRAKE AND REMOVE GN T ON KEY before any
servicing. Be sure all moving parts and all sounds have stopped. Let engine cool and disconnect the spark plugs
so the engine cannot start by accident.
20. KEEP ALL NUTS, BOLTS, AND SCREWS T GHT to be sure equipment is in safe working condition, espe-
cially blade bolts.
21. VEH CLE SHOULD BE STOPPED AND NSPECTED FOR DAMAGE after striking a foreign object and
the damage should be repaired before restarting and operating the equipment. Stop immediately and
check for damage or loose parts if mower should start vibrating.
22. D SENGAGE BLADES BEFORE DR V NG ACROSS WALKS or projecting objects or transporting.
23. KEEP SAFETY DEV CES AND GUARDS N PLACE. f any of the safety switches become inoperable,
have them repaired immediately.
24. DO NOT STEP OR STAND ON THE MOWER HOUS NG. Step or stand only on the tread areas on the deck.
25. WATCH OUT FOR TRAFF C near roadways and when crossing roads.
26. TH S MACH NE S NOT MEANT FOR H GHWAY OR STREET USE. t is not a recreational vehicle and it should
not be operated as such.
27. WHEN FEAS BLE, DO NOT USE MOWER WHEN GRASS S WET OR SL PPERY.
28. MOW ONLY N DAYL GHT OR GOOD ART F C AL L GHT.

SAFETY CONTINUED
29. ALWAYS D SENGAGE THE MOWER BLADE CLUTCH when transporting.
30. Do not operate the mower under influence of drugs or alcohol.
31. Do not change the engine governor settings or overspeed the engine. Operating an engine at excessive speed may
increase the hazard of personal injury.
TOWING
1. Use for towing only if equipped with a Rhino hitch kit. Do not attach towed equipment except at the hitch point.
2. Never allow children or others in or on towed equipment.
3. On slopes, the weight of the towed equipment may cause loss of traction and loss of control.
4. Travel slowly and allow extra distance to stop.
SLOPE OPERATION
1. Use EXTREME caution when mowing and/or turning on slopes as loss of traction and/or tip-over could occur. The
operator is responsible for safe operation.
2. See inside of the back cover to determine the approximate slope angle of the area to be mowed.
3. Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water. This area can be dangerous.
4. Progressively greater care is needed as the slope increases.
5. Alwaysavoidsuddenstartingorstoppingonaslope. f tires losetraction,disengagethebladesandproceedslowlydownthe

Be Alert!
Know where to get assistance. Know how to use a rst
aid kit and re extinguisher/re suppression system.
Be Aware!
Take advantage of training programs offered.
Be Careful!
Human error is caused by many factors: carelessness,
fatigue, overload, preoccupation, unfamiliarity of operator
with the machine, drugs, and alcohol to name a few.
Damage to the tractor or mower can be xed in a short
period of time, but injury, or death, has a lasting effect.
For your safety and the safety of others, encourage your
fellow workers to act safely.
For Safe Operation
You must be a qualied and authorized operator for
proper operation of your machine. You must clearly
understand the written instructions supplied by the
manufacturer, be trained—including actual operation of
the mower—and know the safety rules and regulations
for the worksite. It is a good safety practice to point
out and explain safety signs and practices and ensure
others understand the importance of following these
instructions.
WARNING! Drugs and alcohol affect an operator’s
alertness and coordination and the operator’s ability
to safely operate the equipment. Never use drugs or
alcohol while operating the mowing equipment.
Never knowingly allow anyone to operate this
machine when their alertness or coordination is
impaired. An operator taking prescription or over-the-
counter medication must consult a medical professional

Know The Rules
Most employers have rules governing operation and
maintenance of equipment. Before you start work at a
new location, check with your supervisor or the safety
coordinator. Ask about the rules you will be expected
to obey.
The Occupational Safety and Health Administration
(OSHA) enforces federal laws within the United
States that apply to safe operation, application and
maintenance of equipment on a worksite. It is the
employer’s responsibility to comply with these laws.
An OSHA representative may periodically inspect a
worksite to see that these laws are being followed.
There may also be local or state/provincial laws or
international regulations that apply to this equipment
and its use, along with specic worksite or employer
rules. It is important that you know and comply with
all applicable laws and rules, including those requiring
operator training and certication.
These are some of the rules you must work by:
— A ROPS and seat belt-equipped tractor is a federal
government (OSHA) requirement for operator
protection during mowing operations. An enclosed
cab provides additional operator protection from
thrown objects. Check your mower operator's manual
to see if a tractor cab is also required.
— Wear and check that others are wearing proper
clothing and personal protective equipment.
— Inspect your machine and attachments before each use
as specied by the manufacturer and your employer.
— Know the limitations and operating characteristics of
your mowing equipment. Do not misuse it.
— Have all provided shields and guards properly
installed before operating the machine.
— Never modify or remove any part of the machine
(except for service—then make sure it is replaced).
