Alternating plough

摘要

The reversible plow (1) has a plow frame (3) for connection of the reversible plow with an agricultural tractor in a rotatable and swiveling manner. An adjusting element (14) of a support wheel (4) is supported on an actuation unit. The support wheel is hindered at an actuation movement in the set work depth guide by the actuation unit and the adjusting element. The support wheel together with the actuation element is automatically swiveled in the oppositely aligned stand-by operation position after releasing the actuation unit during the rotation of the plow frame.
