摘要

The disc plough for rough ground has a main beam (1) which can be attached to a tractor. Several lengthwise supports (3) are attached to the main beam (1), by means of hinges. Each support mounts an implement such as plough share or disc (4), to which are connected automatically operating return mechanisms, for overcoming obstacles on the ground. Each return mechanism consists of a top driving rod (6) joined to each lengthwise support (3). Each separate support (3) is fixed to a strut (5) joined to the main beam. The back of the chassis has a land wheel (7) fixed to an arm (8) hinged to the back end of the main beam.
