Troubleshooting, Adjustment & Service
NEUTRAL ADJUSTMENT
If the tractor “creeps” while the ground speed control
levers are locked in NEUTRAL, then it may be neces-
sary 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 37) and turn the
adjustment linkage (A, Figure 37) to adjust. If the
machine creeps forward, turn the linkage CLOCK-
WISE (while standing at the rear of the machine, fac-
ing 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 posi-
tion, 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 operat-
ing 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 38).
Neutral Position Adjustment
1. Loosen the jam nut (D, Figure 38) locked against the
clevis.
2. Turn the reverse return bolt (A, Figure 38) 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 38) length. This should be 2-3/8” long. If not,
hold the reverse return bolt (A, Figure 38) with a wrench
while turning the spring position nut (C, Figure 38) until
the measurement is achieved.
