Semi-mounted reversible plow with rotary amplifier

A semi-mounted reversible plow (1) comprising an attachment frame (5), wherein the attachment frame (5) has a plurality of link points wherein the link points have an upper link (4) and lower links (2, 3) to attach the attachment frame (5) to a tractor, a vertical axis (41) connected to the attachment frame (5), an intermediate frame (13) attached to the vertical axis (41) and a plow frame (7) pivotally attached to the intermediate frame (13), the plow frame (7) carrying a plurality of plow bodies (6), wherein the plow frame (7) is supported via a travel gear (8) with at least one wheel (9), wherein the plow frame (7) is turned into a respective operating position via a slewing gear (10) having a rotational axis (11), a turning arm (12), and a cross-member (33), wherein the slewing gear (10) is connected pivotably with the intermediate frame (13), and the intermediate frame (13) is pivot-mounted in a horizontal direction around the upright standing axis (41) and is overall rotationally freely connected for trailing the tractor and the attachment frame (5) with the lower links (2, 3), wherein a transverse axis (14) is provided between the plow frame (7) and the intermediate frame (13), and a hydraulic cylinder (15) is arranged above the transverse axis and is connected to the cross-member 33 and to the intermediate frame (13), wherein weight of the semi-mounted reversible plow (1) can be transferred to the tractor by the cross member (33), the hydraulic cylinder (15), the intermediate frame (13) and the attachment frame (5), wherein a torque is applied onto the plow frame (7) around the rotational axis (11), wherein the rotational axis (11) of the slewing gear (10) or an imaginary extension (16) of the rotational axis (11) is arranged to cross the plow frame (7) in the operating position on a furrow side from the center of gravity (18) of the plow frame (7).
