Abstract

A drive assembly for an agricultural implement (1) has a first implement portion (2) and a second implement portion (3) pivotable relative to the first implement portion (2) around a pivot axis (x). The first implement portion (2) has a first rotary driving device (4) and the second implement portion (3) has a second rotary driving device (5). The two rotary driving devices (4, 5) are rotationally connected to one another by a shaft assembly (6). The shaft assembly (6) includes a universal joint (7) which adjoins the pivot axis (x). The universal joint (7) includes a cross member with two pairs of arms centered on axes of rotation arranged perpendicularly relative to one another, and two joint yokes. A force-operated setting device (19) transfers the shaft assembly (6) into a rotational position where the axis of rotation of one of the two pairs of arms of the universal joint (7) adjoining the pivot axis (x) at least approaches a parallel line relative to the pivot axis (x). This design enables a pivot movement of the second implement portion (3) relative to the first implement portion (2). A pivot angle is present ranging between 100.degree. and 110.degree.. The implements pivot without the joint yokes of the universal joint (7) contacting one another and without the universal joint (7) being destroyed as a result of any jamming and distortion.
