ABSTRACT:
A female coupling element is secured to a work implement, for locking engagement with a male coupling element pivotably mounted by a boss member at the end of a vehicle boom. The female coupling element includes a pair of curved surfaces positioned for receiving the end of the boom in riding engagement on the boss member. A hydraulic cylinder secured between the boom and the male coupling element relatively pivots the two coupling elements into mating engagement whereupon a separate locking pin carried by the male element is hydraulically actuated from within the vehicle cab for movement to a pin receiving bore carried by the female element, locking the two coupling elements together. The hydraulic cylinder is utilized after implement attachment to manipulate the work implement with respect to the vehicle boom.
