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 Adjust Traction Drive for Neutral in the
Adjustments Section).
WARNING
Before disconnecting or performing any work
on the hydraulic system, all pressure in the
system must be relieved. See Relieving Hy-
draulic System Pressure in the General Infor-
mation section.
5. Connect test gauge with a hydraulic hose attached
to the test port. Make sure hose is long enough so the
operator can read it while driving the machine (Fig. 17).
6. Start engine and move throttle to full speed (2650 +
50 RPM).
CAUTION
Do not operate sidewinder while performing test
.
The test gauge hose may get hit by the sidewind-
er carrier and rupture, and cause personnel inju-
ry.
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 driving the machine up a steep hill
should be about 2500 PSI but can reach relief set-
tings (3000 PSI).
C. 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. 17).
10.If specification is not met, the hydrostat needs to be
repaired or replaced as necessary.
