Test Procedure (continued)
Hydraulic System: Testing the Hydraulic System
7. Use the InfoCenter display to set reel speed control to the full speed setting.
Ensure that the mow/backlap lever on the mow control manifold is in the
M position.
OW
8. Start the engine and run it at low-idle speed. Check for hydraulic-fluid leaks
from the test connections and correct before continuing the test.
The adjacent cutting unit reels will rotate when you perform the
cross-over relief pressure test. Keep away from cutting units during
the test to prevent personal injury from the rotating reel blades. Do
not stand in front of the machine.
Note: This test requires 2 people (one in the seat and one at the cutting
reel motor).
9. Sit on the seat with the engine running, press the engine speed to low speed
(1,175 to 1,225 rpm) position. Use the InfoCenter to check that the engine
speed is correct. Press the reel engage switch to O
the cutting units.
10. There should be a slight hesitation in pressure increase on the inlet side of
motor as the cross-over relief valve opens. Record the pressure reading on
both the inlet and outlet side pressure gauges.
11. Disengage the cutting units and shut off the engine.
12. Calculate the pressure differential between the 2 gauges. If the pressure
differential is not approximately 10,000 kPa (1,450 psi), the cross-over relief
valves on the tested motor may be leaking or damaged. Inspect the relief
valves in the reel motor and replace if necessary; refer to
Cutting Reel Motor (Casappa) (page
13. After you complete the testing, release the cutting unit hydraulic system
pressure; refer to Releasing Pressure from the Hydraulic System (page
Remove the pressure gauges and tee fittings from the machine. Connect the
hydraulic hoses to the reel motor fittings.
14. If necessary, test the cross-over relief pressure on other cutting reel motors.
When testing more than one cutting unit motor, check and adjust the
hydraulic-fluid level in the tank after testing each motor.
15. When testing is complete, start the engine, check for hydraulic-fluid leaks,
repair any leaks as necessary, and fill the hydraulic tank with the correct
quantity of new hydraulic fluid before returning the machine to service.
