Procedure for Traction Circuit Working Pressure
Test:
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately 10
minutes.
2. Park machine on a level surface with the cutting units
lowered and off. Make sure engine is off.
3. Read Precautions For Hydraulic Testing.
4. Make sure that traction pedal is adjusted to the neu-
tral position (see Traction Unit Operator’s Manual).
5. Connect pressure test gauge with a hydraulic hose
attached to the forward test port located on the hydraulic
tube (Fig. 15 and 16). Make sure gauge hose is long
enough so the operator can read gauge while driving the
machine.
6. Start engine and move throttle to full speed (3200 +
50 RPM) .
7. Drive machine in the forward direction. Observe test
gauge.
A. Pressure while transporting the machine over a
flat, level surface should be about
500 PSI .
B. Pressure while mowing should range between
1000 to 2000 PSI and will vary with terrain.
8. Release traction pedal and turn off machine.
9. Disconnect test gauge and hose from the test port
(Fig. 16).
10.If specification is not met, the hydrostat needs to be
repaired or replaced as necessary.
