摘要： A cooling fan drive system for connecting a charge pump to an output of a cooling fan motor. This arrangement allows hydraulic fluid to be suctioned into the charge pump when the charge pump is remote from a hydraulic tank. The cooling fan drive system has a hydraulic tank that stores hydraulic fluid. A cooling fan pump is connected between the hydraulic tank and a cooling fan motor. A connector is connected between the cooling fan motor, the charge pump and the hydraulic tank. This arrangement allows flow of hydraulic fluid from the cooling fan motor to the charge pump.

摘要： A method and apparatus for controlling movement of a work implement movably connected to a work machine. Movement of the work implement is controlled by manual and automatic control valves that are associated with “manual” and “automatic” modes of operation. The manual and automatic control valves are connected between hydraulic motors for controlling movement of the work implement and a hydraulic fluid supply. Each of the manual and automatic control valves governs hydraulic fluid flow to the hydraulic motors. A pressure sensing device is associated with the manual control valves to detect operator modulation of the manual control valves and thereby alter operation of the automatic control valves in the “automatic” mode on the same side of the implement.
