4. Loosen the nut against the neutral control linkage yoke as shown in
Figure 15.
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
levers are in the neutral position, tighten the nuts against the yokes.
c) 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
whenever speed control levers are moved out of the neutral position.
2. Loosen the front nut on
left
hydro control linkage as shown in Figure
15. Turn the rear control linkage adjusting nut counter-clockwise 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 Fig. 16.
