OPERATION
CAUTION: Always stop tractor com-
plete ly, as described above, before leav-
ing the operator's position; to empty
grass catcher, etc.
The operation of any tractor can result in foreign objects thrown into the eyes, which can result
in severe eye dam age. Always wear safety glass es or eye shields while operating your tractor or
per form ing any adjustments or repairs. We rec om mend a wide vision safety mask over spectacles
or stan dard safety glasses.
HOW TO USE YOUR TRACTOR
TO SET PARKING BRAKE (See Fig. 8)
Your tractor is equipped with an operator presence sens-
ing switch. When engine is running, any attempt by the
op er a tor to leave the seat without fi rst setting the parking
brake will shut off the engine.
• Depress brake pedal into full “BRAKE” position and
hold.
• Place parking brake lever in “ENGAGED” position
and re lease pressure from brake pedal. Pedal should
re main in “BRAKE” position. Make sure parking brake
will hold tractor secure.
STOPPING (See Fig. 8)
MOWER BLADES -
• To stop mower blades,move attachment clutch switch
to “DIS EN GAGED” po si tion.
GROUND DRIVE -
• To stop ground drive, depress brake pedal into full
“BRAKE” position.
IMPORTANT : FORWARD AND REVERSE DRIVE PEDALS
RETURN TO NEUTRAL POSITION WHEN NOT DEPRESSED.
ENGINE -
• Move throttle control to slow position.
NOTE: Failure to move throttle control to slow position and
allowing engine to idle before stopping may cause engine
to “back fi re”.
• Turn ignition key to “OFF” position and remove key.
Always remove key when leaving tractor to prevent
un author ized use.
• Never use choke to stop engine.
IMPORTANT: LEAVING THE IGNITION SWITCH IN ANY
POSITION OTHER THAN "OFF" WILL CAUSE THE BATTERY
TO BE DIS CHARGED, (DEAD).
NOTE: Under certain conditions when tractor is standing
idle with the engine running, hot en gine exhaust gases may
cause “browning” of grass. To eliminate this possibility, al-
ways stop engine when stopping tractor on grass areas.

just ment knob in desired direction.

transporting on relatively smooth, straight surfaces. Other
conditions such as trimming at slow speeds may cause the
cruise control to disengage. do not use the cruise control
on slopes, rough terrain or while trimming or turning.
• With forward drive pedal depressed to desired speed,
move cruise control lever forward to “SET” position and
hold while lifting your foot off the pedal, then release
the cruise control lever.
• To disengage the cruise control, pull the lever backward
to “OFF” position, or fully depress the brake pedal.
