Bleeding/Purging the Hydraulic System

IMPORTANT: Air in the hydraulic system is the primary

cause of hydraulic pump failures. Following hydraulic

system service or repair, the hydraulic system MUST be

correctly purged of trapped air before placing the mower

back in operation.

1. To bleed the system make sure the oil tank is full, the

oil must barely cover the fill baffle inside of the tank.

2. Raise the rear unit tires off the floor and place it on

suitable jack stands.

3. Open both pump bypass valves, one on each pump,

two full turns maximum.

4. Sitting in the operator's seat, start the engine and run it

at idle.

5. Slowly cycle the steering control levers full forward and

full reverse for 10 seconds in each direction, 5 or 6

times.

NOTE: The rear tires should rotate, but they'll not be under

load.

6. Shut off the engine, check and add hydraulic oil as

necessary.

7. Close the bypass valves on both pumps. Do not over

tighten.

8. Sitting in the operator's seat, start the engine and run it

at idle.

9. Slowly cycle the steering control levers full forward and

full reverse, 5 or 6 times.

NOTE: It may be necessary to repeat purging procedures

until all air is vented out of the hydraulic system. When the

Pump moves forward and reverse at normal speed and the

reservoir oil remains at a constant level, purging is complete.

IMPORTANT: The rear tires are now rotating under power.

Do not touch or contact them. If they do not rotate after 2-3

cycles, stop immediately. There may still be air in the

system. Let the pumps cool and try purging again from

Step 1.

10. Shut off the engine, lower the unit back to the floor and

check and add hydraulic oil as necessary.

Checking The Hydraulic Hoses

Inspect the hydraulic hoses every 250 hours to ensure they

are in good working order.

Check both the hoses and hose clamps to ensure there is no

wear or damage. If either is found worn or damaged, repair

or replace them at once.
