The plough consists of working bodies (3), which are mounted on a common beam (1), to pivot through 180 degrees on a towing arm. The beam carries a support, for a central pivot axis, which is horizontal in the working position, and oscillating arms, which carry the two wheels (4). The wheel axes are linked to the arms and in the working position, they are roughly orthogonal to the longitudinal direction of the arm, and in the transport position, they are roughly parallel.
