Abstract

A coupling for coupling, for example, a trailer having a drawbar (2) to a tractor with a three-point linkage device, which has two height-adjustable lower steering arms (3, 4) of which one is laterally adjustable by a lateral strut (11). A first coupling element is mounted on the rear of the tractor. The drawbar (2) is provided with a second coupling element (13). The second coupling element (13) is connectable to the first coupling element (12). The coupling has a bar 14 with two ends. Each end includes a connection element (15) to connect with the lower steering arms (3, 4) of the tractor (1). A guiding mechanism comprises two guiding pins is arranged, distanced from each other, on the bar (14). The guiding bar (14) supports the drawbar (2). The drawbar (2) is guided between the guiding pins (17). The drawbar (2) is adjustable relative to the bar (14) in the longitudinal direction. An abutment (20) mounted on the drawbar belongs to the coupling and limits the longitudinal movement when reversing the tractor (1). The lateral alignment of the second coupling element (13) to the first coupling element (12) can be achieved by shortening and elongating the lateral strut (11).
