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 29).
Adjustment
1. Lock the ground speed control lever in the neutral
position.
2. Measure the length of the neutral return spring (C,
Figure 29) 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.
WARNING
To avoid serious injury, perform adjustments
only with engine stopped, key removed and
tractor on level ground.
