Drive System
Maintenance

Adjusting the Tracking

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.
1. Run the machine at 3/4 speed for at least 5 minutes to
bring the hydraulic fluid up to operating temperature.
Stop the machine and wait for all moving parts to stop.
2. Engage the parking brake.
3. Unlatch the seat and tilt the seat forward to gain access
to the tracking knob. Refer to
(page 22).
4. Rotate the knob toward the right to steer right and
rotate toward the left to steer left.
5. Adjust in 1/8 turn increments until the machine tracks
straight.
6. Check and ensure the machine does not creep when it
is in neutral with the parking brake disengaged

Checking the Tire Pressure

Service Interval: Every 40 hours
Maintain the air pressure in the rear tires at 103 kPa (15 psi).
Uneven tire pressure can cause uneven cut. Check the tires
when they are cold to get the most accurate pressure reading.
Note: The rear tire is a semi-pneumatic tire and does not
require air-pressure maintenance.

to 95 ft-lb).

Checking the Wheel Hub Nuts

Service Interval: After the first 100 hours
Every 500 hours
Check and ensure that the torque of the slotted nut is 373 to
475 N-m (275 to 350 ft-lb).
