Implement Connection Example 2

A - Pressure Line

B - Return Line

C - Load Sense Line

D - Control Valve

E - Vacuum Motor

F - Raise/Lower Cylinder

G - Motor Case Drain (Sump Line)

H - Fan

I - Marker

J - Fold

K - Load Sense Coupler

L - Extend Coupler Line

M - Retract Coupler Line

N - Controlled Flow Line

O - Hose Tip

NOTE: For Ag high flow, it is recommended that the hydraulic motor be connected to the top SCV’s (85cc high flow pump).

Not recommended for high flow scraper hydraulics.

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 will cause motor to stop abruptly and may damage seals.
