<p>The plough comprises a frame (4) connected to the transversal beam (3) of the draught-bar head (1), by means of a plough-beam (5) which constitutes one of the sides of the offsetting quadrilateral ABTE. The side AB which is common to the offsetting quadrilateral and the skewing quadrilateral ABCD, is made up of: an arm (22) integral with the frame (4) which extends from the axis B towards the axis A and, a lever (30) articulated between its two ends on an axis (31) arranged at the end of said arm (22), which lever is articulated on one side on axis A and on the other side on the offsetting cylinder (21), which cylinder is directly mounted on the plough-beam (5). The adjusting of the width by the action of the skewing cylinder (25) brings about a variation of the angle at the apex of the triangle formed by the axes A, (19) and (32) which results in the automatic correction of the offset X and gives it a value equal to the distance Z between two consecutive bodies.</p> |
