Perform the rear wheel motor efficiency test if you identify a traction circuit
problem. This test determines if a wheel motor has excessive internal leakage
and wear.
Note: Over a period of time, a wheel motor can wear internally. A worn motor
may bypass the hydraulic fluid internally that reduces the motor efficiency. After
sometime, sufficient fluid loss causes the wheel motor to stall under heavy load
conditions. Continued operation with a worn, inefficient motor can generate
excessive heat, cause damage to the seals and other components in the
hydraulic system and affect overall machine performance.
The traction circuit flow for the Groundsmaster 360 is approximately
57 L/minute (15 gallons/minute). Use a 40 GPM hydraulic tester
#AT40002 (pressure and flow) for this test; refer to
(page 4–27).
1. Ensure that the hydraulic fluid is at normal operating temperature.
2. Ensure that the traction drive is correctly adjusted for the N
Before opening the hydraulic system, operate all the hydraulic
controls to release system pressure and avoid injury from the
pressurized hydraulic fluid; refer to

3. Park the machine on a level surface, lower the cutting deck, shut off the
engine, and set the parking brake.
