See full text

A drawn agricultural machine comprising a carrier frame for carrying processing members, the carrier frame supportable on the ground, at least during transport, by means of a wheel set comprising at least a wheel, a coupling frame for coupling the agricultural machine 1 to the three-point suspension of a tractor, the coupling frame comprising two lower coupling points and an upper coupling point and the coupling frame being rotatable about a vertical axis of rotation relative to the carrier frame. The machine also comprises a drawing element for exerting a force on the coupling frame, wherein the coupling frame, the carrier frame and the drawing element are interconnected in such a manner that a downward force component is exerted on the lower coupling points when the drawing element exerts a force on the coupling frame.
