Abstract
A coupling device for a tractor has a frame (4) which is mounted on the rear underside (3) of the tractor (1). A drawbar (14), with a coupling member (15), is guided in the frame (4). The drawbar (14) is moved by a slide (18) and can be swung sideways about a vertical axis. Centering pieces (34) and stop blocks with centering faces (35) and stop faces (38) engage one another to laterally align and fix the drawbar (14). In a lower position the drawbar facilitates lateral swivelling movement about the connecting pin (22). In an upper towing position the drawbar (14) is laterally fixed by the centering pieces (34) and the stop blocks (38). This results in improved control of the coupling members associated with the to be towed implement through lateral alignment of the drawbar and its automatic transfer into its centered position.
