Troubleshooting, Adjustment & Repair
NEUTRAL ADJUSTMENT
If the tractor “creeps” while the ground speed control
levers are locked in NEUTRAL, then it may be
necessary to adjust the control linkage.
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. Loosen the jam nuts (B, Figure 32) and turn the
adjustment linkage (A) to adjust. If the machine
creeps forward, turn the linkage CLOCKWISE
(while standing at the rear of the machine, facing
forward), if the machine creeps backward, turn the
linkage COUNTER-CLOCKWISE.
3. Lock the jam nuts (B) when neutral is achieved.
NOTE: This adjustment should not be performed
while the machine is running. It may take several
attempts to achieve neutral, depending upon how
much the machine creeps.
NEUTRAL POSITION AND RETURN
SPRING ADJUSTMENT
To determine if it is necessary to adjust the neutral
position, perform the following steps.
1. Disengage the PTO, engage the parking brake
and turn off the engine.
2. Move the ground speed control levers in the
operating position, pull levers rearward and
release.
3. Move the ground speed control levers towards the
neutral position. If the levers do not align with the
notches in the neutral lock plate, it is necessary to
adjust the reverse return bolts (A, Figure 33).
Neutral Position Adjustment
1. Loosen the jam nut (D, Figure 33) locked against
the clevis.
2. Turn the reverse return bolt (A) clockwise to adjust
handle rearward, counter-clockwise to adjust
handle forward.
4. Pull lever rearward and release to check position
again. Adjust as necessary to align levers with
notches.
5. Once the lever alignment has been adjusted, lock
jam nut against the clevis.
Return Spring Adjustment
After adjusting the neutral position, lock the levers in
the neutral position and measure the reverse return
spring (B, Figure 33) length. This should be 2-3/8”
(6,03 cm) long. If not, hold the reverse return bolt (A)
with a wrench while turning the spring position nut (C)
until the measurement is achieved.
