The traction circuit charge pressure test should be per-
formed to make sure that the traction charge circuit is
functioning correctly.
Procedure for Traction Circuit Charge Pressure
Test
1. Parkmachineonalevelsurfacewiththecuttingunits
lowered and disengaged. Make sure engine is off. Apply
the parking brake.
2. Read Precautions For Hydraulic Te sting in this sec-
tion.
3. Raise and support operator seat to allow access to
hydraulic pump assembly.
CAUTION
Before opening hydraulic system, operate all hy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See
Relieving Hydraulic System Pressure in the Gen-
eral Information section of this chapter.
4. Thoroughly clean test port on hydraulic tube be-
tween piston (traction) pump and oil filter (Fig. 30). Con-
nect a 1000 PSI (70 bar) pressure gauge to test port.
