Simple plough having better manoeuvrability

摘要

The plough comprises a support beam (1) for the plough bodies (2) which are pivoted to the beam by stanchions (3). A non-directional wheel (5) is fixed to a stanchion by a non pivoting fixed connection. The stanchions are fixed at a level of a second pivoting axle by a coupling rod (4) so as to constitute a deformable parallelogram. The angle between the beam and the horizontal traction line and the angle between the plough bodies and the beam are adjustable to allow beam orientation. This enables bringing together or separating the bodies relative to the beam so as to obtain a variable width furrow.
