prevent loss of control: 

A.

Operate only in daylight or when there is good
artificial light. 

B.

Drive slowly. Avoid sudden stops and starts. 

C.

Watch for holes or other hidden hazards. 

D.

Look behind machine before backing up. 

E.

Do not drive close to a sand trap, ditch, creek
or other hazard. 

F.

Reduce speed when making sharp turns and
turning on a hillside. 

15.

Traverse slopes carefully. Do not start or stop
suddenly when traveling uphill or downhill. Never
shift axle when moving. Machine must be on a flat
surface and/or brakes must be engaged to prevent
freewheeling. 

16.

Operator must be skilled and trained in how to
drive on hillsides. Failure to use caution on slopes
or hills may cause loss of control and vehicle to tip
or roll possibly resulting in personal injury or
death.

17.

This product may exceed noise levels of 85 dB(A)
at the operator position. Ear protectors are
recommended, for prolonged exposure, to reduce
the potential of permanent hearing damage. 

18.

When operating 4-wheel drive machine, always use
the seat belt and roll-over protection system
together and have seat pivot retaining pin installed. 

19.

If engine stalls or loses headway and cannot make
it to the top of a slope, do not turn machine around.
Always back slowly straight down the slope. 

20.

Raise cutting decks and latch securely in transport
position before driving from one work area to
another. 

21. DON' T TAKE AN INJURY RISK! 

When a

person or pet appears unexpectedly in or near the
mowing area, STOP MOWING. Careless
operation, combined with terrain angles, ricochets,
or improperly positioned guards can lead to thrown
object injuries. Do not resume mowing until area is
cleared. 

22.

Do not touch engine, muffler or exhaust pipe while

3

engine is running or soon after it is stopped. These
areas could be hot enough to cause burns. 

23.

If cutting deck strikes a solid object or vibrates
abnormally, stop immediately, turn engine off, set
parking brake and wait for all motion to stop.
Inspect for damage. If damaged, repair or replace
any components before operating. 

24.

Before getting off the seat: 

A.

Set parking brake. 

B.

Move traction pedal to neutral and axle shift to
HI or LO position. 

C.

Disengage cutting decks and wait for blades to
stop. 

D.

Stop engine and remove key from switch. 

E.

Do not park on slopes unless wheels are
chocked or blocked. 

25.

Use only a rigid tow bar if it becomes necessary to
tow machine. Use trailer for normal transport. 

Maintenance

26.

Before servicing or making adjustments, stop
engine and remove key from the switch. 

27.

Make sure machine is in safe operating condition
by keeping all nuts, bolts and screws tight. 

28.

Make sure all hydraulic line connectors are tight,
and all hydraulic hoses and lines are in good
condition before applying pressure to the system. 

29.

Keep body and hands away from pin hole leaks or
nozzles that eject high pressure hydraulic fluid. Use
cardboard or paper to find hydraulic leaks.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid accidentally
injected into the skin must be surgically removed
within a few hours by a doctor familiar with this
form of injury or gangrene may result. 

30.

Before disconnecting or performing any work on
the hydraulic system, all pressure in system must be
relieved by lowering cutting units to the ground and
stopping engine. 

31. 

If major repairs are ever needed or assistance is
