A coupling device or "quick coupler" which permits the rapid connecting and disconnecting of implements (120) to a hoe boom (113) comprising at least one primary lifting arm (113) fitted for a hinge pin (122) and a "curling linkage" mechanism (115). The quick coupler having a housing (250), which can be temporarily attached to the hoe boom (113) using the hinge and link pins (121, 122) or can be built into the hoe boom (113) itself, and which contains means for attaching the coupling device (261, 270) to a variety of implements. The effective operating distance of the connector can be adjusted so that the coupler can be used with various implements.
