Checking the Control Rod
Adjusting the Control Rod
1. With rear of machine still on jack stands and engine
running at full throttle, move the speed control lever
to “medium” 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.
2. Move the respective drive lever upward until it
reaches the neutral position and engage neutral
locks.
3. If the tire rotates in either direction, the length of the
control rod will need to be adjusted.
1. Adjust the rod length by releasing the drive lever and
removing the hairpin cotter pin and clevis pin. Rotate
the rod in the rod tting (Fig. 0773).
Fig 0773 g. 52 G001733
4. Move the speed control lever to the full forward
position.
5. Squeeze one drive lever until an increased resist-
ance is felt. This is neutral position. This is where the
clevis pin in the yoke comes to the back end of the
slot in the control arm bracket.
Note: Make sure you have not reached the end of
the neutral lock slot. If you have, shorten the
control lever linkage. Refer to Adjusting the
Control Rod.
6. If the wheel turns while holding the drive lever in
neutral, the neutral stud needs to be adjusted (Fig.
0772). If wheel stops then go to step 11.
7. Loosen the nut against the yoke (Fig. 0772).
8. Make adjustments while holding the respective
drive wheel control in the neutral position (increased
resistance) (Fig. 0772).
9. Turn the neutral stud approximately 1/4 turn clock-
wise if the wheel is turning in reverse or turn the bolt
approximately 1/4 turn counterclockwise if the wheel
is turning forward (Fig. 0772).
10. 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.
11. After adjustment is made, tighten the nut against the
yoke.
12. Repeat this procedure for the opposite side.
