Bleeding the Hydraulic System

The traction system is self-bleeding, however, it may be
necessary to bleed the system if fluid is changed or after work
is performed on the system.
1. Disengage the PTO and set the parking brake.
2. Shut off the engine and wait for all moving parts to
stop before leaving the operating position.
3. Raise the rear of the machine onto jack stands high
enough to raise the drive wheels off the ground.
4. Start the engine and move the throttle control to the
idle position.
Note: If the drive wheel does not rotate, it is possible
to assist the purging of the system by carefully rotating
the tire in the forward direction.
5. Check the hydraulic fluid level as it drops, and add fluid
as required to maintain the proper level.
6. Repeat this procedure for the opposite wheel.

Checking the Hydraulic Hoses

Service Interval: Every 100 hours
Check the hydraulic hoses for leaks, loose fittings, kinks, loose
mounting supports, wear, general weathering, and chemical
deterioration. Make any necessary repairs before operating.
Note: Keep areas around the hydraulic system clean from
grass and debris buildup.
Note: Extended operating time at high temperatures in a hot
climate may lead to deterioration of hoses and seals. Inspect
more frequently in a hot climate, and change the hydraulic
fluid and filter more frequently.
