In this application, vacuum motor (D) receives pressure oil from the SCV retract port. Return oil is routed to power beyond return port. When the motor is shut off, the SCV lever is moved to float position.

Control valve (C) is wide open and flow is controlled by tractor control panel. If valve is used to control oil flow, pump will operate at maximum pressure which may cause overheating of hydraulic oil if operating when outside air temperature is high.

Hitch auxiliary raise cylinder oil is connected to auxiliary hitch valve port which is controlled by hitch command lever in the cab.
