Drive System Maintenance
Checking the Tire Pressure
WARNING
Low tire pressure decreases machine side hill stability. This could cause a rollover,
which could result in death or serious injury.
Do not under-inflate the tires.
Note: Maintain the recommended pressure in all tires to ensure a good quality of cut and
proper machine performance.
1. Measure the air pressure in each tire. The correct air pressure in the tires is 83 to 103
kPa (12 to 15 psi).
2. If needed, add air to or remove air from the tires until you measure 83 to 103 kPa (12 to
15 psi).
Torquing the Wheel Nuts
Torque the wheel nuts to 94 to 122 N∙m (70 to 90 ft-lb) in a crossing pattern.
WARNING
Failing to maintain proper torque of the wheel nuts could result in death or serious
injury.
Maintain proper torque of the wheel nuts.
Checking the Rear-Wheel Alignment
1. Rotate the steering wheel to position the rear wheels straight ahead.
2. Prepare the machine for maintenance.
3. At axle height, measure the center-to-center distance at the front and rear of the
steering tires.
Note: The rear wheel toe-in adjustment is correct if the difference between the front
wheel measurement and the rear wheel measurement is 6 mm (1/4 inch) or less.
