Safety Instructions 

Release the steering levers and simultaneously 

(2) Move the FSC to the 

NEUTRAL-PARK

 

position.  When the machine is stopped or 

moving slowly, engage the parking brake.

NOTE:

  The emergency stop procedure is 

exactly the same procedure as used to normal-

ly stop and park this machine.

6.  Disengage the blade clutch, put the FSC in the 

NEUTRAL-PARK

 position, and engage the 

Parking Brake before starting the engine (an 

ignition interlock switch normally prevents start-

ing of the machine if these controls are in the 

OPERATING

 position).

7. 

Do not operate machine if the operator pres-

ence safety switch system is not working.  

Verify proper operation by having the operator 

lift off the seat with the engine running and 

moving three controls, one at a time; (1) Move 

the FSC lever out of the 

NEUTRAL-PARK

 

position, (2) Engage the PTO Clutch, and (3) 

Disengage the Parking Brake.  Moving any of 

these controls should stop the engine immedi-

ately.

8. 

Do not run the engine in a confined area 

without adequate ventilation.  

Exhaust fumes 

are hazardous and can be deadly.

9. 

Do not carry passengers

 - maximum seating 

capacity is one (1) person.

10. 

Avoid sudden starts or stops.  

Before back-

ing the machine up, look to the rear to be sure 

no one is behind the machine.  Watch carefully 

for traffic when crossing or working near road-

ways.

11.  When moving forward, 

do not

 suddenly put the 

tractor in reverse by rapidly pulling on the steer-

ing levers, especially when going downhill, as 

this can lift the tractor tail wheel off the ground 

and set up a bucking motion due to operator 

overcontrol.  If bucking does occur, immediately 

stop the bucking action by pulling the Forward 

Speed Control (FSC) lever into the 

NEU-

TRAL-PARK

 position.

  DANGER

Do not operate tractor within 5 feet (1.5 me-

ters) of an embankment or retaining wall 

with drop off.

12. 

The maximum recommended slope operat-

ing angle in dry conditions is 15 degrees or 

27% grade.  

When operating the machine on a 

slope, reduce speed and use caution to start, 

stop, and maneuver.  To prevent tipping or loss 

of control of the machine, avoid sharp turns or 

sudden changes in direction.  Do not operate 

the machine on a slope greater than 15 de-

grees.

13. 

The maximum recommended slope operat-

ing angle in snow or ice conditions is 5 

degrees or 9% grade. 

Do not operate the 

machine on a snow or ice-covered slope great-

er than 5 degrees.

14.  Operating the machine on snow or ice-covered 

slopes decreases safety.  

It is the operator’s 

responsibility to determine what conditions 

are safe for operation.  

15. 

Do not touch the engine or muffler while the 

engine is running

 or immediately after stop-

ping the engine.  These areas may be hot 

enough to cause serious burns.

16.  When leaving the machine unattended, 

disen-

gage the blade clutch (PTO), engage the 

parking brake, stop the engine, and remove 

the key.

17.  If a PTO-driven implement strikes a solid object 

or the machine begins to vibrate abnormally, 

immediately disengage the PTO clutch, 

engage the parking brake, stop the engine, 

and wait for all moving parts to stop

. Discon-

nect the spark plug wire(s) to prevent acciden-

tal starting. Thoroughly inspect the implement 

and repair any damage before restarting the 

engine and operating the machine. Make sure 

implement components are in good condition 

and all bolts are tight.

NOTE:

  The PTO brake should stop drive line 

rotation within five (5) seconds of disengaging 

the PTO clutch. If the brake is not functioning 

properly, have it repaired by an authorized 

dealer immediately.
