Pivot support wheel (1) for a mounted reversible plow (2), which is connected with the plow frame (4) pivotally around a pivot axis (3) arranged in plow position approximately horizontally and transverse to the working direction, carrying the plow frame (4) on one side plow bodies that turn to the right and, on the opposite side, plow bodies that turn to the left and being rotatably connected around a rotation axis with a three-point tower in such a way that it can be optionally plowed with the side with the plow bodies that turn to the right or with the side with the plow bodies that turn to the left, presenting the wheel of pivoting support (1) a support strut (5) that is joined on one side by means of a joint (6) with the support frame (7) of the pivoting support wheel (1) and, on the other hand, by middle of another joint (8) with the pivoting part (9) or the stem of wheel (25) of the pivoting support wheel (1), whereby the plow frame (4) rests indirectly on the wheel (11) of the pivoting support wheel (1) to limit the working depth of the Reversible plow mounted (2), the support strut (5) presenting a pivot stop (15) that is formed around a guide shaft (16) disposed on the support strut (5) that can be moved during the Rotation process of the mounted reversible plow (2) due to the force of gravity outside the stop position to suppress the support function and can be pivoted back, during and after the rotation process, due to the gravity force of again to the stop position to limit the working depth, the guide shaft (16) being arranged, in a mounted reversible plow (2) in which the pivoting support wheel (1) is transported during the rotation process below of the plow frame (4), in half-turn position and in working position above the center of gravity of the pivot stop (15), characterized in that the support strut (5) has a shock absorber (20) that is formed to brake and / or dampen the pivoting process of the pivoting part (9) of the pivoting support wheel (1).
