Reel Circuit Testing − Reel Motor Efficiency/Case Drain Test
(continued)
Hydraulic System: Testing
2. Park the machine on a level surface with the cutting units lowered and the
PTO switch in the disable position. Make sure engine is off and the parking
brake is disengaged.
3. Read Precautions for Hydraulic Testing (page
4. Make sure that the traction pedal is adjusted to the neutral position.
Note: The cutting unit motors are connected in series. If a faulty reel motor is
not obvious (based on quality of cut issues) you may have to test all the reel
motors in the circuit. If testing all reel motors, start with the first motor.
5. Hydraulic fluid passes through each reel motor from the front to the rear.
Disconnect the return hose from the motor (hose at the rear of the reel motor).
6. Install hydraulic tester between the motor and the disconnected return hose.
Make sure the tester flow control valve is fully open.
7. Make sure backlap knob on the hydraulic manifold is in the MOW position.

1. Inlet hose
2. Case drain hose
8. Disconnect hose from reel motor case drain at the hydraulic tube (#1 cutting
unit), or from the bulkhead fitting (#2 and 3). Cap the hydraulic tube or
bulkhead fitting to prevent system contamination.
9. Place open end of disconnected case drain hose into a drain pan.
10. Two people are required to complete the following steps. One person should
sit in the operator's seat and operate the machine while another person
reads the tester and measures reel motor case drain volume.
11. Start the engine, and move throttle to full speed (2650 ±50 RPM).
12. Verify with a phototach that the pump speed is approximately 3100 RPM.
Keep away from reels during test to prevent personal injury from
the rotating reel blades.
13. Engage cutting units and slowly close tester flow control valve until 82.7
Bar (1200 PSI) is obtained.
