ABSTRACT:
An improved coupling assembly enabling a bucket to be selectively coupled to and uncoupled from a front-end loader with lifting and tilting means. A female coupling structure is integral with the bucket. A back plate of the female coupling structure bears against a front plate of a male coupling structure with no gap between such plates. An upper flange on the front plate bears upwardly against an upper flange on the back plate. Means are provided to latch the male coupling structure releasably to the female coupling structure. Vertical play between the male coupling structure and the female coupling structure is limited precisely to a specified gap between and adjustable member on the male coupling structure and a fixed block on the female coupling structure.
