7. Change the hydraulic filter; refer to Replacing the Hydraulic Filter.

8. Connect the hydraulic hose under the tank.

9. Add fluid to the tank until it reaches the cold baffle of the tank.

   Important: Use the specified fluid or equivalent. Other fluids could cause system damage.

10. Install the hydraulic-tank cap.

11. Start engine and let run for about 2 minutes to purge air from the system.

12. Shut off the engine and check for leaks.

    Note: If 1 or both wheels do not drive, refer to Bleeding the Hydraulic System.

13. Check the level of the fluid and add fluid, if required.

    Important: Do not overfill.

1. Park the machine on a level surface, disengage the PTO, and engage the parking brake.

2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Locate the filter and place a drain pan under the filter (Figure 73).

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 specified fluid 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. Shut off the engine and check for leaks.

    Note: If one or both wheels do not drive, refer to Bleeding the Hydraulic System.

12. Check the fluid level and add fluid, if required.

    Important: Do not overfill.

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. Park the machine on a level surface, disengage the PTO, and engage the parking brake.

2. Shut off the engine, remove the key, 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, 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.

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.

To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, keep extra blades on hand.

1. Remove the locknut, bolt, spring, and spacer holding the deflector to the pivot brackets (Figure 88).
