8. Clean up any spilled fluid.
9. Check the fluid in the reservoir, and add fluid to the
tank until it reaches the cold baffle of the tank.
Important: Use the oil specified or equivalent.
Other fluids could cause system damage.
10. Start the engine and let it run for about 2 minutes to
purge air from the system.
11. Stop the engine and check for leaks.
Note: If one or both wheels will not drive, refer to
Bleeding the Hydraulic System (page
12. Check the level of the fluid and add fluid, if required.
Note: 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 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.
7. Thoroughly clean the area around each of the charge
pump housings.

Checking the Hydraulic Lines
Service Interval: Every 100 hours
Check hydraulic hoses and hoses for leaks, loose fittings,
kinked hoses, 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
oil and filter more frequently.
