Traction Circuit
Refer to “Traction Circuit − Forward” Flow Diagram
A mechanical interlock between the traction pedal link-
age and the parking brake prevents traction pedal
movement unless the brake is released.
Depressing the top of the traction pedal will shift the trac-
tion pump swash plate to direct a flow of oil to the forward
inlet of the traction motors. The oil returns from the mo-
tor to the pump where it continues through the pump in
a closed−loop circuit. System pressure may be moni-
tored at pressure tap port 1.
