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
WARNING
Failing to maintain proper torque of the wheel nuts could cause a wheel to come
loose, which could result in death or serious injury.
Torque the front and rear wheel nuts to 115 to 136 N∙m (85 to 100 ft-lb) after 1 to 4
hours of operation and again after 8 hours of operation. Torque the wheel nuts every
200 hours thereafter.
1. Prepare the machine for maintenance.
2. Torque the wheel nuts to 115 to 136 N∙m (85 to 100 ft-lb).
Note: The front wheel nuts are 1/2–20 UNF; the rear wheel nuts are M12 x 1.6-6H
(metric).
