ABSTRACT:
A vehicle has front brackets which engage with a coupler which has an upright brace with two vertical members joined by a horizontal member. Fixed pins on the brace engage in the bracket slots and retractable spring-loaded pins on the brace engage with the holes on the bracket. A frame is pivotally mounted to the vertical members and is pivotable by an actuator which connects the brace and the frame. A support is pivotally mounted about an axis perpendicular to the frame and has an upturned flange adapted to engage beneath a downturned bracket on the implement and has pinholes located beneath the flange to receive pins extending from the implement. Fixed to the implement is a downturned J-shaped bracket with a vertical portion and a spaced opposed portion which is approximately as deep as the upward extension of the flange on the coupler. Vertical plates are connected on either side of the J-shaped bracket and are spaced to fit on either side of the support of the coupler. Spring-loaded locking pins are located on each vertical plate to travel freely through holes in the plate to engage within the locking holes of the coupler. The vertical plates of the coupling mechanism have rounded out-turned edges which horizontally align the implement coupler with the implement.
