Trailer implement for plough with frame and at least one compactor roller

摘要

At least one compactor roller (2) is mounted on the frame (1) to which two pick-up draw-bars (3) are linked, one pointing in the direction of travel, and the other in the opposite direction. The two draw-bars are hydraulically coupled by a piston cylinder unit (4) between the frame and the pickup draw bar and joined by hydraulic pipes (5). The operating chambers of the piston cylinder units are connected by hydraulic pipe each. The piston cylinder unit is mounted by ball-and-socket joints (6).
