TRACkING ADJUSTMENT
CAUTION
Stop the engine and remove the key from the
ignition before making any adjustments. Wait
for all moving parts to come to a complete stop

Before proceeding with this adjustment, be sure
that the caster wheels turn plus pivot freely and
that the tire pressure in the drive wheels is correct.
If the tire pressure is not correct, the machine will
pull to the side with the lower pressure.
1. If at full speed the mower pulls right, it is an
indication that the left wheel is turning faster than
the right wheel. To adjust this condition, proceed as
follows:
A. Stop the machine and place the steering control
levers in the neutral position. Loosen the lock nuts
securing the ball joints at each end of the LH steering
control rod. Rotate the control rod to lengthen the rod
and tighten the lock nuts. This will cause the control
rod to stroke the LH pump less, slowing down the LH
wheel. (See Figure 6-4, page 24)
If after making the adjustment as outlined in step
1A, the machine creeps forward or backward, the
neutral adjustment must be made as described
on page 24.
2. If at full speed the mower pulls left, it is an indication
that the right wheel is turning faster than the left
wheel. To adjust this condition, proceed as follows:
A. Stop the machine and place the steering control
levers in the neutral position. Loosen the lock nuts
securing the ball joints at each end of the RH steering
control rod. Rotate the control rod to lengthen the rod
and tighten the lock nuts. This will cause the control
rod to stroke the RH pump less, slowing down the RH
wheel. (See Figure 6-3, page 24)
If after making the adjustment as outlined in step
2A, the machine creeps forward or backward, the
neutral adjustment must be made as described
on page 26.
