<p>The plough comprises, in the offset parallelogram ABTE, a jack which provides for the recentering of the frame with respect to the return axis, without modifying the adjustments of the working width and of the offset. This jack is one of the sides of the offset parallelogram. According to one embodiment, it is positioned between the transverse beam (3) and an axis (F) situated midway of the side AE of the offset parallelogram. The offset jack (21) is arranged between the intermediate traverse rod (19) which divides the offset parallelogram and an arm (22) of the frame (4), in order to provide for an automatic correction of the offset of the first body with respect to the tractor upon adjusting the working width.</p> |
