Abstract
Earthmoving machines are often provided with quick coupling devices that allow them to change work implements in a relatively rapid fashion when compared to changing conventionally mounted implements. A locking system between the machine linkage and the implement is positioned between the components and includes a hydraulic system which continually applies pressurized fluid to the locking system.
