A guide and control device for an agricultural machine subjected in operation to a high lateral thrust in relation to its direction of traction, such as a disk-type stubble-plough includes a guide and control system having at the front, a set of freely oscillating twin wheels the orientation of which for a change from a road-travel position to a soil-working position is controlled from a bar for coupling to a tractor. A carrying wheel is arranged in a central part of the frame, and at the rear thereof are arranged freely oscillating twin carrying wheels and furrow wheels controllable simultaneously from their road-travel position to their working position, and vice versa. The multiplicity of carrying wheels guarantees that sufficient grip with the soil is maintained permanently, thus preventing any lateral slip of the machine during passage over a movable obstacle, this also being assisted by the automatic orientation of the twin wheels by means of their freely oscillating mounting.
In a guide and control device for use on an agricultural machine that is subjected during operation to lateral thrust relative to a direction of traction and that includes a frame equipped with soil-working members, front carrying wheels, rear carrying wheels and at least one furrow wheel, said guide and control device including systems for changing the wheels of the machine between respective road-travel positions thereof and respective working positions thereof, the improvement wherein said system for the rear carrying wheels and for the at least one furrow wheel comprises:
