disengaged whenever speed control levers are moved out of the neutral position.

Note: The neutral lock latches should be “unlocked” and in the forward position.

2.Loosen the front nut on left hydro control linkage as shown in Figure 19. Turn the rear control linkage adjusting nut counterclockwise until wheel rotates forward. Turn the rear nut of left control linkage clockwise 1/4 of a turn at a time, stopping to move the speed control forward and back to neutral, until left wheel stops rotating forward.

Turn the rear nut an additional 1/2 turn and tighten the front nut making sure not to put a bind on the linkage. Make sure flat part of linkage is perpendicular to pin part of swivel (see Figure 20).

4.Loosen the nut against the neutral control linkage yoke as shown in Figure 19.

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 levers are in the neutral position, tighten the nuts against the yokes.

•Adjust Hydro Control Linkages:

1.Place the speed control lever in the “neutral” position. This adjustment is again made with rear of machine on jack stands and engine running at full throttle. OPC levers will have to be held down and the park brake must be

After adjusting the left hydro control linkage, move the speed control lever to the mid-speed position and then back to the neutral position. Recheck the left drive wheel rotation to see if further adjustment is necessary - be sure the speed control lever is in the neutral position.

Important: If inconsistent neutral occurs, check to be sure both springs are properly tightened on the speed control lever under the console–especially the rear pivot spring.

Repeat above adjustments if necessary.

3.Place the speed control lever in neutral. Adjust the right side linkage by turning the quick track knob counterclockwise until the tire begins to rotate forward. Begin to retighten the knob clockwise about 1/4 turn at a time, stopping to move the speed control forward and back
