4. Loosen the nut against the neutral control linkage yoke as shown in
Figure 10.
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 10.
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 11.

HYDRO CONTROL LINKAGE/SWIVEL ADJUSTMENT
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.
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 counter-clockwise 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
to neutral. Recheck the drive wheel rotation to see if further
adjustment is necessary.
