support.
a) Stop engine and wait for all moving parts to stop. Remove ignition key or
spark plug wire(s).
b) With PTO disengaged and the bellcrank touching the rear of the slot in the
engine deck, adjust the PTO safety switch (if needed) until the bellcrank arm
is 5/16” from the switch body.

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 (Figure 14). 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 14) 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” between the tab and the switch (See Figure 13). If
necessary, move the switch fore and aft.
