Troubleshooting, Adjustment & Service
NEUTRAL ADJUSTMENT
If the tractor “creeps” while the ground speed control levers are locked in NEUTRAL, than it may be neces- sary to adjust the control linkage.
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.Loosen the jam nut (B, Figure 35) and turn the adjustment linkage (A, Figure 35) to adjust. If the machine creeps forward, turn the linkage CLOCK- WISE (while standing at the rear of the machine, fac- ing forward), if the machine creeps backward, turn the linkage
3.Lock the jam nut (B) when neutral is achieved.
NOTE: This adjustment should not be performed while the machine is running. It may take several attempts to achieved neutral, depending upon how much the machine creeps.
DAMPENER FORCE & NEUTRAL SPRING RETURN ADJUSTMENT
These adjustments will taylor the “feel” of the control levers to the operator.
Each of the dampeners and springs (C and A, Figure
36)has three adjustment holes (D and B, Figure 36). The farther up the dampener and spring are placed, the more effective the dampener becomes and the more spring force will be felt by the operator while driving for- ward.
The closer together the dampeners and springs are placed, the slower the machine will return to NEUTRAL when the control levers are released. The farther apart the dampeners and springs are placed, the faster the machine will return to neutral.
NOTE: These adjustments must be made to BOTH sides at the same time, and be placed in the SAME position to one another.
