Perform neutral adjustment as follows:
1. Put tractor in neutral. Make sure tow valve is secure-
ly in the drive (UP) position or adjustment will not be
accurate. Raise the tractor so that left rear wheel is
on the ground. Support tractor securely with jack
stands (See Elevating Rear End for Safe Service).
Remove the right rear wheel (See Removing Rear
Wheels).
2. Loosen the hardware at locations (B), (C), and (E),
Figure 4.
3. Put weight in seat. Start tractor and run engine at
half-throttle.
4. Use 3/4" open end wrench to turn hex adjuster (A).
Turn until rotation of right axle stops. Tighten nut (E).
5. Shut off engine. Apply parking brake. Tighten nut
(C) at bottom of speed control lever (D) and then
tighten nut (B) at top of speed control lever.
NOTE: Slight rearward (counterclockwise) rotation of
the axle will stop within a few seconds. This small
amount of rotation will not cause tractor creeping and
does not require adjustment.
6. Disengage parking brake and start tractor. Move the
ground speed control lever from forward and reverse
into the neutral gate.
7. If there is minimal rotation of right rear axle, slightly
loosen nut (E) on hex adjuster. Turn hex adjuster just
slightly (turn counterclockwise to correct forward rota-
tion and turn clockwise to correct reverse rotation)
until axle stops. If there is more than slight rotation of
rear axle, repeat steps 2-5.
8. Move the ground speed control lever from forward
and reverse into the neutral gate by depressing the
brake pedal (return-to-neutral pedal). Check that the
shift control lever drops into the neutral gate on dash
and that there is no rear axle rotation.
NOTE: Slight rearward (counterclockwise) rotation of
the axle will stop within a few seconds. This small
amount of rotation will not cause tractor creeping and
does not require adjustment.
9. When adjustment is correct, tighten adjustment nut
(E) to 70-75 in. lbs.
