Disc reversible plow, which comprises: (a) at least one rotatable first cutting element in the form of a cutting disc, by means of which, when the plow is moved through soil to be plowed along a first plowing direction and along a second plowing direction opposite thereto, a side region of a soil bar of the soil is cut, and (b) at least one second cutting element which follows the first cutting element and by means of which, when the plow is moved along the plowing directions (6, 7), a bottom region of the soil bar can be cut off, characterized in that (c) the disc reversible plow is designed with at least one plow module arranged on only one side of a plow module carrier in a single row, (d) the first and second cutting elements are combined to form a plow module which is designed to be replaceable as a fully assembled unit and which is connected to a plow module carrier; (e) the plow module carrier is connected to a connection unit for connecting the disc reversible plow to a drive vehicle via an interposed pivoting unit which replaces a plow beam, the connection unit being connected to the pivoting unit by means of a parallelogram linkage, by means of which an angle formed between the traction line of the drive vehicle and the plow module carrier and defining the plowing width is adjustable by means of an additional pivot axis directed perpendicular to the ground; (f) the pivoting unit is designed to pivot twice in such a way that during the transition from one of the two plowing directions (6, 7) to the other one, the plow module carrier with the at least one plow module is pivotable from its first position to the opposite second position with respect to the connection unit and is additionally pivotable in the second position in the opposite pivoting direction relative to the longitudinal axis of the plow module carrier in such a way and the cutting elements each having such an angle to one another, that without individual adjustment of the cutting elements, the cutting angle and camber angle of the first cutting element remain identical to these angles (16, 17) before the transition from one of the two plowing directions (6, 7) to the other; (g) the second cutting element for cutting the bottom region of the soil bar is designed as an undercutting knife or in the form of a disc; and (h) the connecting unit comprises a first pivot axis which runs essentially in the line of traction and about which the disc reversible plow can be pivoted, and a second pivot axis which enables a second pivoting direction about the longitudinal axis of the plow module carrier which is directed counter to the first pivoting direction of the first pivot axis and via which the connecting unit is connected to the pivoting unit.
