The plough which can work in both directions comprises a coupling to which a traction arm is articulated. The arm other end is articulated to a beam body carrier. The body carrier pivots, spaced along the beam, constitute with the arm and a connecting arm (8), a parallelogram. One point of the parallelogram is connected to a device enabling orientation of the pivots and thus different working widths. A carrying assembly comprising a cross member (11), connected to the beam through an axle (13), supports a wheel (9) on an arm (10). The axle is rotated on the beam by an articulation (14) which connects an arm (15) to the axle. Actuators (25) enable each wheel to oscillate its arm around an axis (27) to allow the working side wheel to rise so that it is not in contact with the ground during working.
