Roller-shaped agricultural appliance for working the ploughed or loosened ground

摘要

Rotatably arranged ring-shaped elements (14, 15, 16) are flanged to one another individually or in groups and are thus mounted rotatably as a complete unit on a central frame (2). The roller-shaped appliance can be widened or reduced, as desired, by flanging ring-shaped elements to one another or unflanging them. The connection of the ring-shaped elements (14, 15, 16) to one another corresponds to the connection to the central frame (2), three connection points (20, 21, 22) being respectively provided approximately centrally between the ring centre point (18) and the ring outer rim (17).
