NEUTRAL ADJUSTMENT
If the tractor “creeps” while the ground speed control levers are locked in NEUTRAL, then it may be necessary to adjust the linkage rod.
NOTE: Perform this adjustment on a hard, level surface such as a concrete floor.
1. Disengage the PTO, engage the parking brake |
| |
and turn off the engine. | B | |
2. There are three nuts (B, Figure 33) on the linkage | ||
A | ||
rod. The first two are to be used together to turn | ||
the rod and the third (towards the front of the | Figure 33. Neutral Adjustment | |
machine) is used to lock the rod in place. Loosen | ||
the jam nut that locks against the ball joint (B, | (RH side shown) | |
Figure 33) and turn the linkage rod (A) to adjust. | A. Adjustment Linkage Rod | |
If the machine creeps forward, turn the rod | B. Nuts | |
| ||
CLOCKWISE (while standing at the rear of the |
| |
machine, facing forward), if the machine creeps |
| |
backward, turn the rod |
| |
3. Lock the jam nut (B) against the ball joint when |
| |
neutral is achieved. |
| |
NOTE: This adjustment should not be performed while | A | |
the machine is running. It may take several attempts | ||
to achieved neutral, depending upon how much the |
| |
machine creeps. |
