If only one wheel is rotating, locate the transmission

control rod beneath the frame at the front of the rear
tire. If both wheels rotate, locate both control rods. See
Figure 7-9.

Remove the flange lock nut and hex screw securing

the transmission control rod to the transmission control
arm. Wheel rotation should stop. If it does not, contact
your Service Dealer.

If the rotation stops, adjust the control rod up or down

as necessary to align with the hole in the transmission
control arm. Re-insert the hex nut into the hole in the
control arm and secure with the hex lock nut.

If necessary, repeat the previous two steps to adjust

the other transmission control rod.

Lower the tractor and remove the jack.

Tractor High Speed Tracking

If the tractor tracks to one side with both drive control
levers fully forward, adjust the control levers as follows:

Check for proper and balanced air pressure in both

front and rear tires. Refill tires if necessary.

Perform the first three steps in the previous sub-

section, Tractor Creeping, to verify that the tractor
is not creeping. If creeping, adjust following the
instructions in that sub-section.

Recheck the tracking after making any adjustments to

the transmission control rods.

If uneven tracking persists, note which direction the

tractor is tracking.

If the tractor tracks to the right, adjust the

control lever stop bolt on the left side.

If the tractor tracks to the left, adjust the control

lever stop bolt on the right side.

Locate the applicable stop bolt on the left or right

console. See Figure 7-10.

Loosen the jam nut on the stop bolt, then turn the

stop bolt counterclockwise to make it longer. Recheck
the tracking and fine tune the adjustment as necessary.

NOTE:

If the stop bolt is adjusted too far, the

tracking problem will change sides. Make fine tuning
adjustments by shortening the same bolt.

Tighten the jam nut against the console and reposition

the control lever as necessary to make the two control
handles even with each other.
