Using Low-Pressure Return Circuit

The electro-hydraulic hitch valve has a convenient port (A) to access the tractor hydraulic sump.

Examples of implements which cannot withstand high pressure applied to both ports are:

Hydraulic motors which have the return and case drain ports connected. Failure of the motor housing or shaft seals may result if the return line is pressurized.

Remote hydraulic valves located on the implement may allow unexpected movement of cylinders if the return port is pressurized.
