Abstract/ A coupling frame (4) that is permanently connected to the draw bars (3) of a tractor hydraulic drawbar system is provided to permit simple and reliable coupling by driving a tractor up to a machine. A connector frame (10') which is of box-section profile material is arranged on the machine and this has flanges only on two of the triangle sides that run from the apex, these projections extending towards the tractor. These projections are slid over the side surfaces of the coupling frame (4) so as to provide a shape-locking coupling of the coupling frame (4) with the connector frame (10' )./ A cross-piece (6) is provided to support the drive shaft dog clutch (8)./ (Figure 4)/
