Neutral Adjustment - (Linkage with two ball joints)
If the tractor creeps forward or back with transmission in
neutral notch, adjust as follows.
1. Seat yourself in the operator’s seat and start the
engine.
2. Move the lever to position where tractor remains
stationary. This is neutral position.
3. Stop the engine.
4. Disconnect the battery cables to avoid causing short
circuit or sparks with tools.
5. The control lever quadrant (A, figure 7-1) is mounted
with slotted holes so it can be adjusted. Loosen the
two self-tapping screws (C) and move the quadrant so
the lever is centered in the quadrant gate. Then
tighten the two screws.
6. Connect the battery cables.
7. Lower the seat deck. Start the engine to check again. If
the tractor still creeps in neutral, proceed to step 8.
8. Return the quadrant to the center position, if moved.
Loosen the front nut (A, figure 7-2) and rear nut (B)
on the hydro shift rod (C). The rear nut is a left-hand
thread.
9. Using an open-end wrench, turn the hex shaft (D)
three turns upwards (toward the frame) if the tractor
Is creeping forward, or downward (toward the
ground) if the tractor is creeping backwards.
10. Hold hex shaft and tighten front and rear nuts (A & B,
figure 7-2).
11. Repeat steps 1 through 7 to read just the hydro lever
in the neutral gate.
12. Repeat entire procedure until tractor does not creep
with hydro lever in neutral gate.
