NEUTRAL POSITION ADJUSTMENT __________________________________________

If the tractor "creeps" in either direction, the neutral position
must be adjusted.
1. Adjust nut (K) in 1/16 or 1/8 turn increments.
a. To adjust for reverse creep, loosen nut (J) and turn
nut (K) to thread rod (L) into rod end (M).
b. To adjust for forward creep, loosen nut (J) and turn
nut (K) to thread rod (L) out of rod end (M).
2. Close operator's platform and drive the tractor both
forward and reverse on level ground. Return pedal
to neutral and check to see if tractor creeps in either
direction.
3. Repeat steps 1 and 2 until the tractor no longer
creeps.

4.10 NEUTRAL START SWITCH __________________________________________________

switch. Switch must be readjusted whenever neutral
position has been changed.
2. Use a Volt/Ohm meter to determine when switch
opens or closes.
a. Loosen hardware (N) and adjust neutral plate (O)
until switch (P) closes. Tighten hardware (N).
b. Switch should open when pedal is moved out of
neutral in either direction and close when pedal
returns to neutral.

4.11 4WD REVERSE SWITCH ____________________________________________________

1. Adjust neutral start switch (P) before adjusting 4WD
reverse switch (Q).
2. Use a Volt/Ohm meter to determine when switch
opens or closes.
a. Loosen hardware (R) and adjust switch (Q) until
switch just opens with traction pedal in neutral.
Tighten hardware (R).
b. Switch should close when pedal is pressed for
forward movement and open when pedal is

pressed for reverse movement.
