Abstract
A drive assembly for an agricultural implement ( ) has a first implement portion ( ) and a second implement portion ( ) pivotable relative to the first implement portion ( ) around a pivot axis (x). The first implement portion ( ) has a first rotary driving device ( ) and the second implement portion ( ) has a second rotary driving device ( ). The two rotary driving devices ( ) are rotationally connected to one another by a shaft assembly ( ). The shaft assembly ( ) includes a universal joint ( ) which adjoins the pivot axis (x). The universal joint ( ) 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 ( ) transfers the shaft assembly ( ) into a rotational position where the axis of rotation of one of the two pairs of arms of the universal joint ( ) 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 ( ) relative to the first implement portion ( ). A pivot angle is present ranging between 100° and 110°. The implements pivot without the joint yokes of the universal joint ( ) contacting one another and without the universal joint ( ) being destroyed as a result of any jamming and distortion.
