•
If the left rear tire is rotating in reverse, lengthen
the rod by slowly turning the rod counter-clockwise
(as viewed from the front) until the left rear tire
stops rotating or minimal rotation is detected in
reverse
•
If the left rear tire is rotating forward, shorten the
rod by slowly turning the rod clockwise (as viewed
from the front) until the left rear tire stops rotating.
4. Move the throttle to the Fast position. Make sure the
wheel remains stopped or minimal creep is detected in
reverse. Adjust as required.
5. Tighten the jam nuts.
6. Repeat the procedure for the right rear tire, if required,
by using the right side transmission control rod .

4. Adjust the stop bolt all the way in (away from the
traction pedal).
5. Using your hand, push the traction pedal all the way
forward, with light pressure, until it stops and hold it
there. Maintain only light pressure on the pedal when
pushing it to the full forward position.
6. With the seat in the raised position, verify that you
are not over loading the linkage by making sure
the transmission does not move when the pedal is
depressed to the stop.
7. Adjust the stop bolt out (towards the traction pedal)
until there is a gap of 1.5 mm (0.060 inch) between the
head of the stop bolt and the bottom of the traction
pedal.
8. Tighten the jam nut to secure the stop bolt in place.
9. The reverse stop bolt may be adjusted if the maximum
reverse speed is not acceptable. For a faster reverse
speed, adjust the stop bolt in. For a slower reverse
speed, adjust the stop bolt out.
