No adjustment necessary.
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 (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 (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.
