OPERATION
The operation of any tractor can result in foreign objects thrown into the eyes, which
can result in severe eye damage. Always wear safety glasses or eye shields while op­
erating your tractor or performing any adjustments or repairs. We recommend a wide
vision safety mask over spectacles or standard safety glasses.
HOWTO 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
operator to leave the seat without first setting the parking
brake will shut off the engine.
• Depress clutch/brake pedal into full "BRAKE” position
and hold.
• Place parking brake lever in “ENGAGED” position and
release pressure from clutch/brake pedal. Pedal should
remain 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 “DISENGAGED” position.
GROUND DRIVE -
• To stop ground drive, depress clutch/brake pedal into
full “BRAKE" position.
• Move gearshift lever to neutral (N) position.
ENGINE-
• Move throttle control between half and full speed (fast)
position.
NOTE: Failure to move throttle control between half and
full speed (fast) position, before stopping may cause engine
to “backfire”.
• Turn ignifion key to "STOP” position and remove key.
Always remove key when leaving tractor to prevent
unauthorized use.
• Never use choke to stop engine.
IMPORTANT: LEAVING THE IGNITION SWITCH IN ANY
POSITION OTHER THAN "STOP" WILL CAUSE THE BATTERY
TO BE DISCHARGED, (DEAD).
NOTE: Under certain conditions when tractor is standing
idle with the engine running, hot engine exhaust gases may
cause "browning” of grass. To eliminate this possibility, al­
ways stop engine when stopping tractor on grass areas.
A
CAUTION: Always stop tractor com­
pletely, as described above, before
leaving the operator's position; to empty
grass catcher, etc.
TO USE THROTTLE CONTROL (See Fig. 8}
Always operate engine at full fhrottle.
•
Operafing engine at less than full throftle reduces fhe
battery charging rate.
• Full throttle offers the best mower performance.
TO USE CHOKE CONTROL (See Fig. 8)
Use choke control wheneveryou are starting a cold engine.
Do not use to start a warm engine.
• knob in to disengage.
TO MOVE FORWARD AND BACKWARD
(See Fig. 8)
The direction and speed of movement is controlled by the
gearshift lever.
• Start tractor with clutch/brake pedal depressed and
gearshift lever in neutral (N) position.
• Move gearshift and range shift levers to desired po­
sition.
• Slowly release clutch/brake pedal to start move­
ment.
IMPORTANT: BRING TRACTOR TO A COMPLETE STOP
BEFORE SHIFTING OR CHANGING GEARS. FAILURE
TO DO SO WILL SHORTEN THE USEFUL LIFE OF YOUR
TRANSAXLE.
TO ADJUST MOWER CUTTING HEIGHT
(See Fig. 8)
The cutting height is controlled by turning the height ad­
justment knob in desired direction.
• Turn knob clockwise ( ) to raise cutting height.
• Turn knob counterclockwise (*^) to lower cutting
height.
The cutting height range is approximately 1-1/2" to 4-1/2".
The heights are measured from the ground to the blade tip
with the engine not running. These heights are approximate
and may vary depending upon soil conditions, height of
grass and types of grass being mowed.
• The average lawn should be cuf to approximately 2-1/2
inches during the cool season and to over 3 inches
during hot months. For healthier and better looking
lawns, mow often and after moderate growth.
• For best cutting performance, grass over 6 inches
in height should be mowed twice. Make the first cut
relatively high; the second to desired height.
