5.2.6 Hydro Drive Linkage Adjustment
:
a) Adjust Speed Control Linkage and Neutral Safety Switch
1. Stop engine and wait for all moving parts to stop.
2. Move the speed control lever (located on the console) to the full
forward position and check the orientation of the tabs on the ends of
the speed control crank (See Figure 12). These tabs should be
pointing straight down at the 6 o’clock position or slightly forward.
Adjust the threaded yoke at the bottom of the speed control linkage
(See Figure 12) until the tabs are positioned correctly.
3. Pull the speed control lever back to neutral. Check that the neutral
safety switch actuating tab has depressed the plunger of the switch so
that there is about 5/16” (.79 cm) between the tab and the switch (See
Figure 12). If necessary, move the switch fore and aft.

NEUTRAL SAFETY SWITCH ADJUSTMENT
b) Adjust Neutral Control Linkages
1. Raise the rear of the machine up onto jack stands high enough to raise
the drive wheels off of the ground.
2. Start the engine and move the throttle ahead to the full throttle position.
Place the neutral lock latches in the “forward” position as shown in Figure
6 and move the speed control lever to the “mid-speed” position.
Note: The OPC levers must be held down whenever the speed control
lever is out of the neutral position or the engine will kill.
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 wheels stop then go to step 7.
