Tractor Creeping
Creeping is the slight forward or backward movement of the
mower when the throttle is on and the speed control pedals are
in the neutral position. If your mower creeps, see an authorized
service dealer.
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. Check hydraulic fluid level (Ref. Engine owner's manual)
3. Perform the steps in the previous section, Tractor Creeping,
to verify that the tractor is not creeping.
4. Recheck the tracking after making any adjustments to the
transmission control rods.
5. If uneven tracking persists, adjust as follows:
a. If the tractor tracks to the right, adjust the left
control lever stop bolt to make it longer. See Fig. 7-6.
Figure 7-6
b. If the tractor tracks to the left, adjust the right
control lever stop bolt to make it longer.
5. 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.
