The reversible plough has a towed chassis (2), which carries the working body (15) of the plough, which, in turn, is fitted with the working tools (21, 23). The working body has a symmetrical plane (16), perpendicular to the working plane. It is equipped with two plates (33 ,34), at the lower end, to form the counter stocks. These are arranged symmetrically on either side of the plane of symmetry and to the rear of the body, in the sense of advancement of the plough. The counter stocks are mounted to be able to pivot freely around the respective axes (49,50), which are parallel to the working plane and are also symmetrical on either side of the plane of symmetry.
