Troubleshooting, Adjustment & Service
TRANSMISSION FOOT CONTROL
PEDAL NEUTRAL ADJUSTMENT
If the tractor “creeps” (gradually moves forward or
backwards) while the transmission foot control pedal
is in the neutral position, then it may be necessary
to adjust transmission foot control pedal neutral
adjustment.
1. Park the machine on a flat, level surface.
Disengage the PTO, stop the engine, and engage
the parking brake.
2. Loosen the set collars (A, Figure 30) that are
located on the top and bottom of the neutral return
spring (F.)
3. Loosen the neutral lock plate hardware (B.) If the
machine creeps forward, slide the neutral lock
plate (C) and the pump control arm (D) slightly to
the right. If the machine creeps backwards, slide
the neutral lock plate and the pump control arm
slightly to the left. Retighten the hardware that
secures the neutral lock plate.

4. Refer to 30. Make sure that the top plastic
bushing (E) is seated tightly against the top of the
neutral return bracket (G). Make sure that the
bottom plastic bushing (E) is seated tightly against
the bottom of the neutral return bracket. Tighten
the set collars (A).
NOTE: This adjustment should not be performed
while the machine is running. It may take several
attempts to achieve neutral, depending up how much
the machine creeps.
