Troubleshooting, Adjustment & Repair
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.
2. There are three nuts (B, Figure 41) on the linkage |
|
| A | |||
rod. The first two are to be used together to turn |
|
| B |
| ||
the rod and the third (towards the front of the |
|
|
| |||
|
|
|
| |||
machine) is used to lock the rod in place. Loosen | Figure 41. | Neutral Adjustment |
| |||
the jam nut that locks against the ball joint and |
|
| ||||
turn the linkage rod (A) to adjust. If the machine |
| (LH side shown) |
| |||
creeps forward, turn the rod CLOCKWISE (while |
| A. Adjustment Linkage Rod |
| |||
standing at the rear of the machine, facing |
| B. Nuts |
|
| ||
forward), if the machine creeps backward, turn the |
|
|
| |||
rod |
|
|
|
|
|
|
3. Lock the jam nut (B) against the ball joint when |
|
|
|
| ||
neutral is achieved. | Reproduction |

NOTE: This adjustment should not be performed | for |
|
| |||
|
|
|
| |||
while the machine is running. It may take several |
|
|
|
| ||
attempts to achieved neutral, depending upon how |
|
|
|
| ||
much the machine creeps. |

To determine if it is necessary to adjust the neutral |
|
|
| |||
return, perform the following steps. |
|
|
|
|
|
|
1. Disengage the PTO, engage the parking brake |
|
|
|
| ||
and turn off the engine. |

2. Move the ground speed control levers into the |
| A. Return Spring |
| |||
|
|
|
| |||
| operating position, pull levers rearward and | B. Set Collar |
|
| |
| release. |
|
3. | Move the ground speed control lev rs out towards |
|
| the neutral position. If the levers do not align |
|
| with the notches in the neutral lock plate, it is |
|
| necessary to adjust the neutral return rod. |
|
To Adjust: |
| |
1. | Loosen the set collar (B, Figure 42) locked against |
|
| the return spring (A). |
|
2. | Lock the ground speed control levers in neutral. |
|
3. | Tighten set collar against the return spring. |
|
4. | Pull lever rearward and release to check that the |
|
| lever stops aligned with notch in the neutral lock |
|
| plate. |
|
It is important to note that after every adjustment of the neutral return spring, the lever must be returned to locked position to properly check the neutral position.
