On Ag high flow hydraulics-equipped tractors, it is recommended to correct hydraulic motor powered components to top SCVs. The SCVs receive oil from system 85cc high flow pump.

In this motor application (E) is being operated from power beyond which requires a load sense connection (C) to signal hydraulic pump for operation.

The second motor (H) is equipped with motor case drain (sump line) (G). Pressure oil comes from the retract port on the SCV and return oil is routed to the extend port. When motor return oil is routed to an SCV, a special return hose tip (O) with check valve is required to prevent high pressure oil from moving back toward the motor and possibly damaging the seals. When the motor is shut off, the SCV lever is moved to float position to allow motor to coast to a stop. Moving lever to neutral causes motor to stop abruptly and can damage seals.
