Mow Circuit Problems
Problem
Possible Causes
All the 3 front cutting reel motors do not operate but rear
cutting reel motors operate.
• The solenoid valve MSV2/SP2 on the mow control manifold
is damaged.
Note:
The solenoid valves MSV1/SP1 and MSV2/SP2 are
identical and can be reversed for testing purposes.
• The mow/backlap lever for the front cutting units (MR2/MV2)
is not rotated fully.
• An electrical problem exists that prevents MSV2/SP2
solenoid coil on the mow control manifold from being
energized (refer to
Troubleshooting (page 7–26)
or the
Electrical Schematic and Wire Harness Drawings/Diagrams
in
Appendix A (page A–1)
).
• The front cutting reel(s) is (are) binding.
• The gear pump section (P2) is worn or damaged.
Both rear cutting reel motors do not operate but front cutting
reel motors operate.
• The solenoid valve MSV1/SP1 on the mow control manifold
is damaged.
Note:
The solenoid valves MSV1/SP1 and MSV2/SP2 are
identical and can be reversed for testing purposes.
• The mow/backlap lever for the rear cutting units (MR1/MV1)
is not rotated fully.
• An electrical problem exists that prevents MSV1/SP1
solenoid coil on the mow control manifold from being
energized (refer to
Troubleshooting (page 7–26)
or the
Electrical Schematic and Wire Harness Drawings/Diagrams
in
Appendix A (page A–1)
).
• The rear cutting reel(s) is (are) binding.
• The gear pump section (P1) is worn or damaged.
A single cutting reel motor does not operate, rotates slowly,
or stops under load.
• The relief valve in the mow control manifold is bypassing.
• Traction speed and cutting conditions (e.g., very tall or wet
grass) exceed cutting unit capacity.
• The cross-over relief valve in the cutting reel motor is
stuck or damaged. (Reelmaster 5510/5510-D/5610/5610-D
machines)
• The cutting reel motor is worn or damaged.
• The cutting reel motor has internal leakage (bypassing fluid).
• The gear pump section (P2 or P3) is worn or damaged.
Note:
If appropriate, transfer a suspected damaged motor
to another cutting reel. If problem follows the motor, motor
needs to be repair or replacement.
