Abstract
A coupling and centering device is attached to a journal (38) of a carrying frame (37) of an agricultural implement. The coupling and centering device has a catching ball (7) and a catching profile (14). The catching profile (14) has a sleeve (15) and a catching plate (25) which are connected to one another. The sleeve (15), in the fitted condition, enters a bore step (12) of the catching ball. The catching plate (25) is arranged relative to the sleeve (15) such that the transverse bore (19), for receiving the lynch pin, is arranged in the region of the wall of the catching plate (25). Thus, in view of a predetermined length of the journal (38) and the provision of the fixing bore (39), the greatest possible guiding length of the sleeve (15) is achieved on the journal (38). In this way, the strength of the connection is affected positively.
