Draft frame agricultural machine with dome shaped tire roller

摘要

The agricultural machine includes a tracked support frame (24) and a roller (10) comprising a tube (12) rotatably assembled around a horizontal axis (XX) on stages (22) connected to the frame. The tube is equipped with a series of tires (16) threaded on it and presenting respective circumferential domed profiles to form a series of parallel furrows in the ground. To allow a use in a field and on the road without raising of the roller, the machine includes a braking device (28,30,32,34) for exerting a controlled resistive torque between the support frame and the central tube.
