Adjusting the Transmission
for Neutral
If the machine creeps when the traction control pedal is in
the neutral position, the neutral return mechanism must be
adjusted.
1. Block up under the frame so that one of the front
wheels is off of the floor.
Note: Note: If machine is equipped with a 3 wheel
drive kit, also raise and block rear wheel.
2. Start the engine, move the throttle to Slow, and check
the front wheel that is off of the floor; it must not be
rotating.
3. If the wheel is rotating, stop the engine and proceed
as follows:
A. Loosen the nut securing the eccentric to the top
of the hydrostat (Figure 51).

B. Move the functional control lever to Neutral and
the throttle to Slow. Start the engine.
C. Rotate the eccentric until creep does not occur in
either direction. When the wheel stops rotating,
tighten the nut locking the eccentric and the
adjustment (Figure 51). Verify the adjustment
with the throttle in the Slow and Fast position.
Note: If the wheel still turns when the eccentric
is at the maximum adjustment, contact your
Authorized Service Distributor or refer to the
Service Manual for further adjustment.

Adjusting the Transport Speed

The traction pedal is adjusted for maximum transport speed
at the factory, but an adjustment may be required if the pedal
reaches full stroke before it contacts the pedal stop, or if a
decrease in transport speed is desired.
Press down on the traction pedal. If the pedal contacts
the stop (Figure 52) before tension is felt on the cable, an
adjustment is required:

1. Pedal stop
1. Loosen flangehead locknuts securing the pedal stop to
the floor plate (Figure 52).
2. Adjust the pedal stop so it contacts the pedal rod and
tighten the nuts.
