control linkage until tabs are positioned correctly. See Figure 14.

3.Pull speed control lever back to neutral. Check that the neutral safety switch actuating tab has depressed the plunger of the switch so that there is about 5/16 inch (7.9 mm) between the tab and the switch as shown in Figure 14. If necessary, move the switch fore and aft.

5.Adjust the neutral control linkage until the respective drive wheel stops when the lever is pulled against the neutral spring (neutral position). Turn the adjusting bolt approximately 1/4 turn clockwise if the wheel is turning in reverse or turn the bolt approximately 1/4 turn counterclockwise if the wheel is turning forward. Release the drive lever to the forward drive position and squeeze back into the neutral position. Check to see if the wheel stops. If not, repeat the above adjustment procedure.

6.Make this adjustment on both sides.

7.After adjustments are made and the wheels stop when the drive lever is in the neutral position, tighten the nut against the yokes.

Neutral Control Linkages Adjustment

1.Raise the rear of the machine up onto jack stands high enough to raise the drive wheels off of the ground.

2.Start the engine and move the throttle ahead to the full throttle position. Place the neutral lock latches in the “forward” position as shown in Figure 4 and move the speed control lever to the “mid-speed” position.

Note: The park brake must be disengaged and the OPC levers must be held down whenever the speed control lever is out of the neutral position or the engine will kill.

3.Squeeze the respective drive lever until an increased resistance is felt; this is where neutral should be.

If the wheel turns while holding the drive lever in neutral, the neutral control linkages need to be adjusted. If wheels stop then go to step 7.

4.Loosen the nut against the neutral control linkage yoke as shown in Figure 15
