Abstract

A device which attaches an agricultural implement (2) to a tractor (1), and in addition, establishes a driving connection between the power take-off shaft of the tractor and the drive of the implement has, for this purpose, a drive unit (8) which includes two bevel gear angle drives (9, 10) arranged one above the other. One of the drives (9, 10) is firmly connected to the drawbar of the implement with the other one connectable to the lower steering arm of the tractor by an attaching stirrup (12). The attaching system allows the tractor and implement to pivot relative to one another around a vertical axis (25), a transverse axis (26) and a longitudinal axis (27). To achieve pivotability relative to the drive unit (8) around the longitudinal axis (27), the attaching stirrup (12) is supported by a sleeve (47) on a flange housing (39) which is arranged coaxially relative to the first connecting journal (20) of the drive unit (39) thereby achieving an improvement in the transmission of towing forces.
