2. Determine which reel motor is malfunctioning.
Note: The reel motors are connected in series. To iso-
late a faulty motor, you may have to test all three motors
in the circuit by starting with the upstream motor first.
3. Lower cutting units, engage parking brake and stop
the engine.
4. Install a tee fitting between the motor inlet fitting and
hose. Install a 5000 PSI (350 Bar) pressure gauge on
the tee fitting (Fig. 20).
5. Set reel speed control to the full speed position. Make
sure Mow/Backlap valve is in the "Mow" position.
6. With cutting units in lowered position and engine OFF,
insert a block of wood between cutting unit reel blades
and front cross tube of cutting unit to prevent reel from
turning (Fig. 20).

7. One person should sit on the seat and operate the
machine while another person reads the tester. Start the
engine and move "Enable/Disable" switch to ENABLE.
Move "Lower-Mow/Raise" lever forward to engage the
cutting units.
DESIRED TESTER READING:
Approx. 1400 to 1600 PSI (96.5 to 110.3 bar).
8. Disengage the cutting units and stop the engine. If
pressure is less than 1400 PSI (96.5 bar), cross-over re-
lief valve on motor is malfunctioning or there is internal
leakage in the reel motor and the motor efficiency should
be checked.
