ABSTRACT:
A quick coupler for mounting a variety of implements to a vehicle, such as a lawn and garden tractor, is provided. The coupler easily mounts on the vehicle and receives powered or non-powered implements. The coupler includes pivot structure and hydraulic actuators to allow it swinging movement about a horizontal axis or the implement angling movement about a vertical axis. Interference between the coupler structure and drive line of the vehicle is eliminated as the coupler or implement is swung about their respective axes by positioning the angling cylinder below the PTO drive line and locating it between two coupler frame plates.
