摘要： The invention concerns a multi-ploughshare (5) plough (1) with variable working width, comprising at least a support beam (2, 3) for angularly mobile ploughshares (5) and ploughshares (5) consisting respectively of a plough beam (6) linked via a leg of a plough (7) to the working parts (8) including at least a frog (9) and a landside (10). The plough is characterised in that the ploughshares (5) are mounted freely pivoting between two extreme working width positions relative to the support beam (2, 3) via a pivot pin (14), the leading edge (17) of the working parts (8) of the ploughshare (5) being located substantially downstream of said pivot pin (14) such that the landside (10) of the ploughshare (5) in working position is self-aligned along a line parallel to the traction line (T) when the plough moves forward.

摘要： The invention concerns a device for controlling forces passing through the push bar (3) of the three-point hitch of a tractor vehicle (1) whereto is hitched a semi-mounted machine (7) via a double tree (5) and a gimbal-type linking component (6) interposed between the double tree (5) and the semi-mounted machine (7). Said device is characterized in that it consists of a control member (10, 1OA, 1OB) arranged between the linking component (6) and the semi-mounted machine (7) front part, said member (10, 10A, 10B) exerting an adjustable thrust or tensile force on the semi-mounted machine in a direction for pivoting the machine about a horizontal axis (D2) towards the ground and causing, by reaction of the semi-mounted machine (7) transmitted to the push bar (3) the tensile forces passing through the push bar (3) to be cancelled, reversed and/or modulated. The invention is applicable to a plough.

摘要： Semimounted reversible gang plough, comprising ploughing bodies mounted on a boom (12) with a front member (12a) and a rear member (12b) joined by a hinge element (13) and a control unit (19) for rotating the rear member (12b) relative to the front member (12a) and locking the hinge member (13) in a selected angular position thereof, wherein the boom (12) is rotatably mounted about a longitudinal shaft (8) of a support (9) with lifting wheels (10). The invention is characterised in that the means for rotatably attaching the boom (12) to the support (9) are integral with the rear member (12b) of said boom (12). The invention is useful for handling or transporting ploughs.
