Reel Circuit Testing − Pressure Test (continued)
2. Make sure backlap knob on the hydraulic manifold is in the MOW position.
Make sure that the reel speed knob is set for typical mowing conditions.
3. Read
Precautions for Hydraulic Testing (page 5–27)
.

4. Remove cap from test fitting at mow control manifold port (G1) and install a
pressure gauge with hydraulic hose to the test fitting (
CAUTION
Keep away from cutting units during test to prevent personal injury
from the cutting blades.
5. Sit in the Operator’s seat, start the engine, and move throttle to full speed
(2650 ±50 RPM).
6. Make sure that the hydraulic fluid is at normal operating temperature by
operating the machine for approximately 10 minutes. Make sure that the
hydraulic tank is full.
7. Verify with a phototach that the pump speed is approximately 3100 RPM.
8. Set the cutting unit speed control to #9 (maximum) and engage the cutting
units.
When engaged, the cutting circuit pressure may exceed manifold relief valve
pressure setting of
207 Bar (3000 PSI)
momentarily opening the relief valve.
Circuit pressure should then stabilize at approximately
83 Bar (1200 PSI)
.
9. Safely secure the test pressure gauge and operate the machine under your
specific mowing conditions. Monitor test gauge while mowing. reel circuit
pressure should be approximately:
103 to 138 Bar (1500 to 2000 PSI)
under
low to normal load conditions.
10. Disengage cutting units, move throttle to low speed and shut off the engine.
11. If pressure readings are within specifications and cutting unit performance is
still in question, test cutting unit motors individually (see
− Reel Motor Efficiency/Case Drain Test (page 5–43)
).
12. If pressure specifications are not met, consider the following:
A. Solenoid valve (SV) is faulty (see
Reel Circuit Testing − Manifold Relief
Valve (SV) Pressure Test (page 5–49)
).
