Abstract
A quick coupler assembly connects an implement to a work machine. The coupler assembly includes a cylindrical catcher rotatably mounted between a pair of plates. During coupling of the implement with the coupler assembly, the catcher is rotated at a cam surface by an implement coupling pin which allows a latch member mounted to the pair of plates to slidingly engage automatically with the catcher for locking the catcher in a closed position. The closed position of the catcher locates a jaw thereof in a position which retains the implement coupling pin within a receiving notch of the catcher thereby coupling the implement to the work machine. The ability to couple an implement to a work machine with ease and simplicity in conjunction with the utilization of durable components, increases usability and reliability while reducing costs.
