Reelmaster 7000−D Hydraulic SystemPage 5 − 63
Cutting Unit Circuit − Relief Pressure Test
Two relief valves are used in the Reelmaster 7000−D
cutting unit circuit. Relief valve RV1 protects the front
cutting unit circuit powered by gear pump section P2,
and relief valve RV2 protects the rear cutting unit circuit
powered by gear pump P3. Test the performance of the
mow control manifold relief valves RV1 or RV2 to make
sure that the maximum amount of fluid is available to the
cutting unit motors up to the set relief pressure.
Special Equipment Required:
S 15 GPM (56 LPM) Hydraulic Tester (Pressure
and Flow) with hoses − 1 − 14
S Phototach (non−contact tachometer)
1. Park machine on a level surface with the cutting units
lowered and the reel enable/disable switch in the DIS-
ABLE position. Engine should be off and the parking
brake engaged. Make sure that the backlap levers on
the mow control manifold are in the mow (F) position.
CAUTION
Prevent personal injury and/or damage to equip-
ment. Read all WARNINGS, CAUTIONS and Pre-
cautions for Hydraulic Testing at the beginning
of this section.
2. Determine cutting unit circuit relief pressure to be
tested:
A. The tester connection point for relief valve RV1
(front cutting units − gear pump section P2) is at the
cutting unit #4 motor supply hose (front hose)
(Fig. 39).
B. The tester connection point for relief valve RV2
(rear cutting units − gear pump section P3) is at the
cutting unit #2 motor supply hose (front hose)
(Fig. 39).
3. Thoroughly clean junction of appropriate hydraulic
supply hose and cutting unit motor fitting. Disconnect
the supply hydraulic hose from the motor.
IMPORTANT: Make sure that the oil flow indicator
on the tester matches the flow of oil (disconnected
hose > tester > hydraulic motor).
4. Install tester with pressure gauge and flow meter in
series with the disconnected hose and cutting unit motor
fitting. The tester hydraulic hoses must be long enough
to safely view the tester while sitting in the operator’s
seat. Make sure the flow control valve on the tester is ful-
ly open.

5. Start engine and run at low idle speed. Check for hy-
draulic leakage and make corrections if necessary be-
fore proceeding with test.
6. Set throttle to high speed.
A. Use the InfoCenter display to verify engine RPM
on units with Yanmar diesel engines (2850 RPM).
B. Use a phototach to verify engine RPM on units
with Kubota diesel engines (2850 +50/−120 RPM).
7. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately ten
(10) minutes.
CAUTION
Cutting unit blades will rotate when lowered with
enable/disable switch in ENABLE position. Keep
away from cutting units during test to prevent
personal injury from rotating blades. Do not
stand in front of the machine during test.
8. Sit in the operator’s seat, set the mow speed limiter
to the LOW speed (mow) position, release the parking
brake and engage the cutting units.
9. Watch tester pressure gauge while slowly closing the
tester flow control valve. As the relief valve opens, sys-
tem pressure should be from 2800 to 3200 PSI (193 to
220 bar).
10.Open the tester flow control valve, disengage cutting
units and stop the engine. Record test results.
