Drive System
Maintenance
Checking the Tire Pressure
Service Interval: Every 25 hours—Check tire pressure.
Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut. Check
the pressure at the valve stem (Figure 49). Check the tires
when they are cold to get the most accurate pressure reading.
Refer to the maximum pressure suggested by the tire
manufacturer on the sidewall of the caster wheel tires.
Inflate the rear drive wheel tires to 13 psi.

Changing the Hydraulic
System Filter and Oil
The filter and oil are changed at the same time. Do not reuse
oil. Once the new filter is installed and oil is added any air in
the system must be purged.
The bleeding process is repeated until the oil remains at the
FULL COLD line in the reservoir after purging. Failure to
properly perform this procedure can result in irreparable
damage to the transaxle drive system.
