The connecting aggregate has a tow bar with a coupling hook from which a coupling ring is formed, and which has a ducted cylinder (22). The coupling hook is like a pulling ball (3), whilst the coupling ring is formed like a pulling ball (4). The connecting aggregate also comprises a rotation console (8) that is adapted on the same level like the top rod of the tractor, and on which, at one end, is rotatably stopped in a mounting (11). The ducted cylinder has an end that is rotatable on the rotation console on a upstanding swivel pin (12), whilst the piston rod (23) of the cylinder is rotatably fitted, on the other end, on the mounting on an upright swivel pin (24). |
