ABSTRACT:
A device for connecting an agricultural implement to a tractor, towing it and driving it, via a power take-off shaft, has a double drive (8) which includes two angle drives (15, 16) which are arranged one above the other and which are pivotable relative to one another via a bearing around a first axis. The double drive (8) is associated with a holding bracket (9) and with a support (36) supported thereon via springs. The support (36) has a bearing journal via which is connected to a transverse bar (7) so as to be pivotable around an axis. The transverse bar (7) serves to connect the implement to the catching hook of the lower steering arms (3) of the tractor (1). These permit a pivot movement around the axis. The support (36) ensures improved conditions when accommodating forces in the case of impacts.
