Pivoting support wheel for mounting on a plow frame

A rotary plow (1) with pivoting support wheel (2) for mounting on a plow frame (3) of the rotary plow (1), wherein the plow frame (3) comprising a plurality of mirror-inverted plow bodies (4, 4′) lying opposite one another in pairs, which are brought from a right-hand turning into a left-hand turning position by a rotation of nearly 180°,

• wherein said pivoting support wheel (2) is comprised of a support wheel (5) and an arm (6),
• wherein said support wheel (5) is pivotably mounted on the plow frame (3) for depth limitation of the plow bodies (4, 4′) by means of said arm (6), wherein the arm (6) that is supporting the support wheel (5) is limited in its pivot angle about a first axis (8) parallel to the ground surface (7) or running through a middle plane (20) of the plow frame (3) upon rotating the plow frame (3), and is locked into a right-handed or left-handed position corresponding to the plow orientation following this rotation by an additional device,
• characterized in that
• the movement of the arm (6) is about the first axis (8) in a driving direction and describes a maximum angle (α) of 160°, wherein the arm (6) or the support wheel (5) is mounted to rotate about a second forwardly-inclined axis (9) which is arranged in a plane running perpendicular to the ground surface (7) and parallel to the driving direction, wherein the second forwardly-inclined axis (9) is arranged in front of a wheel contact point (10) in order to form an intersection point (11) with the ground surface (7), which forms an imaginary guide point, around the driving direction of the support wheel (5).
