Neutral Adjustment
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 (B, Figure 30).
ADJUSTMENT
1. Lock the ground speed control lever in the neutral
position.
2. Measure the length of the neutral return spring (C,
Figure 30) it should be set at 3.25” (8,23cm). If the
spring does not measure 3.25” (8,23cm) loosen the
front set collar (D) and the rear set collar (A), then
move the front set collar forward or back on the neutral
return rod (B) until the spring length equals 3.25”
(8,23cm). Retighten the front set collar.
3. Make sure that the neutral return bushing (E) is seated
correctly in the spring stop plate (F).
4. Position the rear set collar so that it sets tightly against
neutral return bushing and tighten.
5. Pull the ground speed control lever rearward and
release to check position again. Adjust as necessary to
align the ground speed control levers with the notches
in the neutral lock plate.
It is important to note that after every adjustment of the
neutral return rod, the lever must be pulled rearward and
released to properly check the neutral position.
NEUTRAL ADJUSTMENT
If the tractor “creeps” while the ground speed control levers
are locked in NEUTRAL, than 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) 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.
