check for leaks. If one or both wheels will not drive,
refer to Bleeding Hydraulic System.
13. Recheck level and add fluid, if required. Do not
overfill.
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. Stop the engine and wait for all moving parts to stop
before leaving the operating position.
3. Raise the rear of the machine up onto jack stands
high enough to raise the drive wheels off the ground.
4. Start the engine and move the throttle control to idle
position.
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 add fluid
as required to maintain the proper level.
6. Repeat this procedure for the opposite wheel.
7. Thoroughly clean the area around each of the charge
pump housings.
