Tracking Adjustment
The tracking knob is located under the seat.
Rotating this knob allows fine tuning adjustments so
that the machine tracks straight with the drive levers in
the full forward position.

control lever at full forward speed to bring hydraulic
system oil up to operating temperature.
2. Engage the parking brake.
3. Tilt seat forward to gain access to the tracking knob.
4. Rotate the knob towards the right to steer right and
rotate towards the left to steer left.
5. Adjust in 1/8 turn increments, testing after each
adjustment, until the machine tracks straight.

when in neutral with the parking brakes disengaged
(Figure 31).
