Motion Control Linkage Neutral Adjustment
Place the tractor on a level surface with engine running.
Depress the brake pedal and release. The tractor should not
creep and the rear wheels should be effectively locked.
If the tractor creeps on a level surface while in neutral.
adjust as follows:
1. Block the
rear
wheels oft the ground.
2. Remove controls cover plate located in front of the seat.
3. Loosen the set screws in the arm with an allen wrench.
See Fig. 5-12.
4. Start the engine and run at full throttle.
Engage the
drive clutch. Allow drive train to reach normal operating
temperature.
5. Depress the brake pedal fully and release.
6. Insert a short screwdriver through the hole in the nylon
cam and rotate the eccentric cam pin until the
rear
wheels stop turning. This usually occurs at a point mid-
way between forward and backward wheel rotation.
The lobe on the eccentric pin must be up for proper
adjustment.
7. Retighten the set screw in the arm and retest for neutral
at full throttle.
5-4
If the brake band is severely out of adjustment (too
tight), proper neutral adjustment will not be possible
due to restricted brake pedal travel.
Loosen brake
band adjustment nut completely, make the neutral
adjustment, then adjust the brake band.

Adjustment
Detent Alignment Adjustment
After neutral has been adjusted, check to see if the
motion control lever is centered in the detent notch of the
detent spring. The spring incorporates slotted bolt holes so
it may be adjusted as required to line up the neutral notch
with the control rod. See Fig. 5-11.
Motion Control Friction Adjustment
The speed control lever is friction-loaded to hold any
selected speed in either direction. If the lever does not re-
main where it is set during operation, adjust as follows:
1. Remove controls cover plate.
2. Release large locknut. See Fig. 5-11.
3. Tighten friction collar to desired spring friction.
4. Tighten large locknut.
The proper amount of friction is obtained when
approximately 61bs. (1.4 N) of force at the top of the
handle moves the control
lever.
The friction collar is
self-lubricating and does not require added lubrication.
Brake Adjustment
The brake band, located on the left side of the trans-
mission, brakes the transmission and, in turn, brakes the
rear wheels. As the brake pedal is depressed, linkage returns
the transmission to neutral, dynamically braking the trac-
tor.
The brake band is actuated after the transmission
reaches neutral, providing additional braking action. The
brake band also serves as the parking brake.
To adjust the brake on C-Series automatic tractors,
follow the preceding procedure outlined under "S-Speed
Models." See Fig. 5-13.
