Neutral Adjustment
Note: Perform this adjustment procedure only if tractor
moves forward or reverse when ground speed control
lever is in neutral gate.
1. Place jackstand under each side of rear drawbar.
Adjust jackstand height until rear wheels are off the
ground.
2. Hydro transmission has pre-set internal neutral
adjustment. If tractor creeps when control lever is in
neutral, first loosen nut (A, figure 6-1) securing shift
rod lever (B) to shift pivot assembly (C). Directional
cam (E) will return to factory pre-set neutral. If wheels
continue to move with control lever in neutral, a
problem exists with internal adjustment. Contact the
Service Department. If wheels do not move, perform
the following steps to align cams.
3. Loosen nut (D) securing lever assembly pivot.
4. With nut (A) loosened, make sure ground speed
control lever is in neutral slot on dash.
5. Push spring-loaded directional cam (E) side-to-side
and allow cam to return-to-neutral.
6. With cam (E) stationary, move shift pivot assembly
(C) until 1/4" hole in cam and pivot assembly line up.
Insert 1/4" positioning pin (F) or 1/4" rod thru both
parts. Cam (E) must remain in neutral position.
7. With positioning pin in place, tighten nut (D) and
then tighten nut (A).
8. Remove positioning pin and move ground speed
control lever through forward and reverse ranges and
return lever to neutral.
9. Check to see if positioning pin can be freely inserted
(from bottom side) through directional cam (E) and
lever assembly (C). If alignment if good, go to step 10.
If pin cannot be inserted, repeat steps 2-8.
10. With ground speed control lever in neutral position,
start tractor (with rear wheels off the ground) and
check for wheel movement. Wheels should not move
due to internal neutral adjustment. If wheels move,
recheck that positioning pin can be inserted freely
through directional cam (E) and lever assembly (C)
with ground speed control lever in neutral position.
If neutral cannot be found, a problem exists with the
tractor shift linkages.
11. After neutral adjustment, move the ground speed
control lever to forward range and depress clutch/
brake pedal. The control lever should return to the
neutral position in dash and wheels should not move.
Move ground speed control lever to reverse range and
repeat check.
