NEUTRAL ADJUSTMENT
If the tractor “creeps” while the ground speed control
levers are locked in NEUTRAL, then it may be
necessary to adjust the linkage rod.
NOTE: Perform this adjustment on a hard, level
surface such as a concrete floor.
1. Disengage the PTO, engage the parking brake
and turn off the engine.
2. There are three (3) nuts on the linkage rod. The
first two are to be used together to turn the rod
and the third (towards the front of the machine) is
used to lock the rod in place. Loosen the jam nut
that locks against the clevis (B, Figure 29) and
turn the linkage rod (A) to adjust. If the machine
creeps forward, turn the rod CLOCKWISE (while
standing at the rear of the machine, facing
forward), if the machine creeps backward, turn the
rod COUNTER-CLOCKWISE.
3. Lock the jam nut (B) against the clevis when
neutral is achieved.
NOTE: This adjustment should not be performed
while the machine is running. It may take several
attempts to achieved neutral, depending upon how
much the machine creeps.

SPEED BALANCING ADJUSTMENT
If the rider veers to the right or left when the ground
speed control levers are in the maximum forward
position, the top speed of each of these levers can be
balanced by turning the adjustment bolt(s) (A, Figure
28). Only adjust the speed of the wheel that is
traveling faster.
To Reduce the Speed of the Faster Wheel
1. Loosen the flange nuts.
2. turn the top speed adjustment bolt COUNTER-
CLOCKWISE to reduce the speed.
3. Retighten the flange nuts when adjustment is
complete.
WARNING
DO NOT adjust the tractor for a faster overall
speed forward or reverse than it was designed
for.
