Pivoting support wheel for mounting on a plow frame

Rotary plow (1) with pivoting support wheel (2) for mounting on a plow frame (3) of a rotary plow (1), wherein the plow frame (3) comprising a plurality of mirror-inverted plow bodies (4, 4′) lying opposite one another in pairs may be brought from a right-hand turning into a left-hand turning position by a rotation of nearly 180°, wherein a support wheel (5) is pivotably mounted on the plow frame (3) for depth limitation of the plow bodies (4, 4′) by means of an arm (6), wherein the arm (6) supporting the support wheel (5) is limited in its pivot angle about a first axis (8) at least approximately parallel to the ground surface (7) or at least approximately running through the middle plane (20) of the plow frame (3) upon turning of the plow frame (3), and may be locked into a respective working position corresponding to the plow orientation following this rotation by a further device,

• characterized in that
• the movement of the arm (6) takes place about the first axis (8) in the direction of travel or is aligned forwards and describes a maximum angle (α) of 160°, wherein the arm (6) or the support wheel (5) is mounted to rotate about a second axis (9) which is arranged in a plane running at least approximately perpendicular to the ground surface (7) and at least approximately parallel to the direction of travel, wherein the second forwardly-inclined axis (9) is arranged in front of the wheel contact point (10) in order to form an intersection point (11) with the ground surface (7), which forms an imaginary guide point, around which the support wheel 5 follows.
