lock latches in the “forward” position as
shown in Figure 4. Release the park brake
and move the speed control lever to the
“mid-speed” position.
Note:
The OPC levers must be held down
and the park brake must be disengaged
whenever the speed control lever is moved out
of neutral or the engine must begin shutdown.
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 the wheel stops then
go to step 7.

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
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 20. 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 21).
