摘要： 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.

摘要： 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.

摘要： A plough consisting of a frame made of two portions (3, 5) interconnected above the supporting carriage (2) along a transverse axis (6) that is horizontal when the plough is in its use position, said portions being further held in alignment by spring buffers (7). Said plough comprises, adjacent to the transverse axis (6), a pivot member (10) and a runner (11) for converting the connection into a kind of universal joint whereby the rear portion (5) is movable along the central plane of the frame (1), in particular during transport.
