Purging the Air from the Hydraulic System

Due to the effects air has on efficiency in hydraulic drive systems, it is critical that it be purged from the system. These purge procedures should be implemented any time a hydraulic system has been opened to facilitate maintenance or any additional oil has been added to the system.

The resulting symptoms of air in the hydraulic system may be:

• Noisy operation.

• Lack of power or drive after short term operation.

• High operation temperature and excessive expansion of oil.

Before starting, make sure the transaxles/transmissions are at the proper oil levels. If it is not, fill to the specifications outlined in the

Check / Fill Transmission Oil Level

Purging Air from the Hydraulic System:

1. Chock the front wheels to prevent the machine from rolling. Raise the rear of the machine so that the vehicle’s rear tires do not contact the ground. Position jack stands under the rear bumper of the machine to secure it.

2. Open the transaxle’s bypass valves (see location and function of the bypass valves), start the engine, release the parking brake, and slowly move the zero-turn rider’s ground speed control levers in both forward and reverse directions (5 to 6 times), as air is purged from the unit, the oil level will drop.

3. Stop the engine and engage the parking brake.

4. Close the transaxle’s bypass valves, start the engine, release the parking brake, and slowly move the zero-turn rider’s ground speed control levers in both forward and reverse directions (5 to 6 times), as air is purged from the unit, the oil level will drop.

5. Stop the engine. Remove the jack stands from underneath the machine.

6. Repeat the process detailed above but with the unit's drive wheels on the ground. The procedure should be performed in an area free of any objects or bystanders.

It may be necessary to repeat the process detailed above until all the air is completely purged from the system. When the transaxles/transmissions operate at normal noise levels and move smoothly forward and reverse at normal speeds, then the transaxles/transmissions are considered purged.

Parking Brake Adjustment

The parking brake mechanism consists of a single parking brake rod that connects the parking brake handle to the lower parking brake shaft. The lower parking brake shaft connects two (2) transaxle brake linkage rods to the transaxles. There is one linkage rod per transaxle. On each linkage rod there is one parking brake spring and a set collar. The parking brake is adjusted by changing the compressed spring length of the parking brake spring and the position of the set collar.

1. Park the unit on a flat, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn ignition switch to OFF, and remove the key.

2. Locate the two (2) parking brake springs (A, Figure 26). The parking brake springs are below the hydraulic oil reservoir tanks on each side of the machine.

3. With the parking brake engaged, measure the compressed spring length (B) of the parking brake springs. The measurement is taken on the front edge of the spring which is the side that is most compressed with the parking brake engaged. The parking brake springs should measure 1-1/8" (2.86 cm) when compressed.

4. Loosen the hardware (A, Figure 27) the retains the handle bar guard (B) and tilt it forward. Loosen the two (2) jam nuts (C) on either side of the neutral lock out plate (D) and turn the adjustment bolt (E) until the measurement of 1-1/8” (2.86 cm) is achieved on the compressed parking brake springs. Tighten the jam nuts.
