Abstract
An implement support frame or holder is mounted to an end of a boom for swinging about a horizontal, transverse axis. A pair of transversely spaced, tapered locating pins are mounted to a horizontal, transverse member of the support frame. The pins are each provided with a front surface that is curved on a radius about the transverse pivot axis and a gradually tapering rear surface. The pins are symmetrical about a fore-and-aft extending vertical plane with the curved forward surface acting to aid in guiding the pins into circular receptacles provided in an upper rear horizontal member of the implement.
