5. Turn the knob clockwise 1/4 of a turn at a time. Then
move the speed control forward and back to neutral.
Repeat this until right wheel stops rotating forward
(Fig. 47).
6. The spring that keeps tension on the knob should
normally not need adjustment. However, if adjustment
is needed, adjust the length of the spring to 1 inch
(26 mm) between the washers (Fig. 47).
7. Adjust spring length by turning the nut at the front of
the spring (Fig. 47).
8. After adjusting the right hydro control linkage, move
the speed control lever forward and then back to the
neutral position.
9. Make sure the speed control lever is in the neutral
position and the tire does not rotate.
10. Repeat adjustment if needed.

4. Move the speed control lever to the full forward
position (Fig. 40).
5. Squeeze one drive lever until an increased resistance
is felt (Fig. 50). 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 (Fig. 50). If you have, shorten the control
rod. Refer to Adjusting the Control Rod on page 40.
6. If the wheel turns while holding the drive lever in
neutral position, the neutral stud needs to be adjusted
(Fig. 43). If the wheel does not rotate, then go to
step 12.
7. Loosen the nut against the yoke (Fig. 48).
8. Adjust the adjustment stud until the respective drive
wheel stops while holding the drive in neutral position
(increase resistance) (Fig. 43).
9. Turn the adjusting bolt approximately 1/4 turn
clockwise if the wheel is turning in reverse and turn
the bolt approximately 1/4 turn counter–clockwise if
the wheel is turning forward (Fig. 43).
