Abstract: A rotary plow (1) with pivoting support wheel (2) for mounting on a plow frame (3). The pivoting support wheel (2) is suitable for plows projecting far behind, such as multi-plowbody mounted, reversible plows or semi-mounted reversible plows with a movable rear part. Furthermore, the pivoting support wheel (2) exhibits self-steering characteristics which have different support or steering forces which act on the pivoting support wheel (2) or the plow frame (3) through the pushed or forwardly-directed arrangement of the pivot arm, and thus enables an accurate lateral guidance of the plow.

Abstract: The invention relates to a pivoting support wheel (2), which is aligned and pushed forwards, for a reversible plough (1), said wheel guiding the reversible plough into a determined working position and has self-guiding properties which prevent adverse lateral forces to the plough.
