Tractor High Speed Tracking
If the tractor tracks to one side with both drive control
levers fully forward, adjust the control levers as follows:
1. Check for proper and balanced air pressure in both
front and rear tires. Refill tires if necessary.
2. 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.
3. Recheck the tracking after making any adjustments to
the transmission control rods.
4. If uneven tracking persists, note which direction the
tractor is tracking.
a. If the tractor tracks to the right, adjust the
control lever stop bolt on the left side.
b. If the tractor tracks to the left, adjust the control
lever stop bolt on the right side.
5. Locate the applicable stop bolt on the left or right
console. See Figure 7-9.
6. 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.
7. Tighten the jam nut against the console and reposition
the control lever as necessary to make the two control
handles even with each other.
