Adjustments
Adjust 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 one of the front wheels
is off the floor. If machine is equipped with 3 wheel drive
kit, raise and support rear wheel off the floor as well.
Chock wheels not being lifted to prevent the machine
from moving.
2. Start engine, move throttle to SLOW and check
wheel that is off shop floor; wheel must not be rotating.
3. If the raised wheel is rotating, stop engine and pro-
ceed as follows:
A. Loosen both jam nuts securing traction control
cable to bulkhead on hydrostat. Make sure jam nuts
are loosened equally and sufficiently to allow adjust-
ment.
B. Loosen nut securing eccentric to the top of the
hydrostat.
C. Move functional control lever to neutral and
throttle to slow. Start engine.
D. Rotate eccentric until creep does not occur in ei-
ther direction. When the wheel stops rotating, tight-
en nut locking eccentric and adjustment. Verify
adjustment with throttle in SLOW and FAST posi-
tions.
E. From each side of the bulkhead, tighten locknuts
evenly , securing traction cable to the bulkhead. Do
not twist cable.
Note: If cable tension exists when in neutral, machine
may creep when the functional control lever is moved to
the Mow or Transport position.

Adjust Transport Speed
The traction pedal is adjusted for maximum transport
speed at the factory, but an adjustment may be required
if pedal reaches full stroke before it contacts pedal stop,
or if a decrease in transport speed is desired.
1. Press down on traction pedal and see if pedal con-
tacts stop before tension is felt on cable. If an adjustment
is required:
A. Loosen flange head locknuts securing pedal
stop to floor plate.
B. Adjust pedal stop so it contacts pedal rod before
minimum tension is felt on the cable. Tighten nuts.
