HOW TO USE YOUR TRACTOR
Your tractor is equipped with an operator
presence sensing 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.

pedal into full
=BRAKE" position and hold.
• Place parking brake lever in "EN-
GAGED"

The motion control lever
does not return to neutral (N) position
when the clutch/brake
pedal is 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
=backfire".
• Turn ignition key to "OFF" 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 =OFF" will cause
the battery to be dishcarged
(dead).
NOTE:
Under certain conditions when
tractor is standing idle with the engine run-
ning, hot engine exhaust gases may
cause =browning" of grass. To eliminate
this possibility, always stop engine when
stopping tractor on grass areas.
_,
CAUTION:
Always stop tractor com-
pletely, as described above, before leaving
the operator's position; to empty grass
catcher, etc.
THROTTLE
CONTROL
Always operate engine at full throttle.
• Operating engine at less than full throt-
tle reduces the battery charging rate.
• Full throttle offers the best bagging and
mower performance.
TO MOVE FORWARD
AND BACKWARD
The direction and speed of movement
is
controlled by the motion control lever.
• Start tractor with motion control lever in
neutral
(N) position.
• Release parking brake and clutch/brake

The cutting height is controlled by turning
the height adjustment knob in desired
direction.
• Turn knob clockwise (G) to raise cutting
height.

The cutting height range is approximately
1-1/2" to 4". The heights are measured
from the ground to the blade tip with the
engine not running. These heights are ap-
proximate and may vary depending
upon
soil conditions, height of grass and types
of grass being mowed.
• The average lawn should be cut to
approximately
2-1/2
inches during the
cool season and to over 3 inches during
hot months.
For healthier _nd better
looking lawns, mow often a_d after
15
moderate growth.
