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 nuts (B, Figure 31) 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 ball joint (B,
Figure 31) 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 ball joint 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.
RETURN-TO-NEUTRAL
ADJUSTMENT
To determine if it is necessary to adjust the neutral
return, perform the following steps.
1. Disengage the PTO, engage the parking brake
and turn off the engine.
2. Move the ground speed control levers into the
operating position, pull levers rearward and
release.
3. Move the ground speed control levers out towards
the neutral position. If the levers do not align with
the notches in the neutral lock plate, it is
necessary to adjust the neutral return rod.
TO ADJUST:
1. Loosen the set collar (B, Figure 32) locked against
the return spring (A).
2. Lock the ground speed control levers in neutral.
3. Tighten set collar against the return spring.
4. Pull lever rearward and release to check that the
lever stops aligned with notch in the neutral lock
plate.
It is important to note that after every adjustment of
the neutral return spring, the lever must be returned
to locked position to properly check the neutral
position.
