4.Loosen the nut against the neutral control linkage yoke as shown in Figure 12.

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 counter- clockwise 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.

c)Adjust Hydro Control Linkage:

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 whenever speed control lever is moved out of neutral position.

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

2.Loosen the front nut on left hydro control link as shown in Figure 13. Turn the rear control linkage adjusting nut counter-clockwise until wheel rotates forward. Turn the rear nut of left control link 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 nut an additional 1/2 turn and tighten the front jam 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 12.
