ABSTRACT:
An attachment frame is connected with a loader arm of a work machine for connecting an implement thereto. A latch member is operatively associated with the attachment frame and movable between a disengaged position and an engaged position. A link has a first end portion connected to the latch member and a second end portion. A pivot member has a first end portion pivotally connected on the attachment frame, a second end portion pivotally connected on the second end portion of the link, and a central portion. A cylinder has a head end portion connected to the attachment frame and a rod end portion connected to the central portion of the pivot member. The cylinder is connected with a supply of hydraulic fluid so that upon pressurization thereof the cylinder is actuated for moving the latch member between the disengaged and engaged positions to respectively detach and attach the implement to the work machine.
