Abstract

Semi-mounted reversible plows with a length of several meters and a support wheel that carries the plow frame and a stabilizer running parallel to the support frame can easily follow the towing vehicle even in tight curves, as the plow frame is connected to the plow front frame or the swivel arm via a swivel head with a fixable swivel joint. In addition to the swivel joint in the joint head, a further joint can expediently be provided, which is arranged transversely to the swivel joint and enables a favorable width adjustment of the plow frame. Locking bolts with compression springs or notches or the like can be used to fix the swivel joint.
