Abstract

A coupling device for attaching a power lift of a tractor to an attachment includes a link mounting region having coupling units for the articulation of an upper link and two lower links of the power lift, and an apparatus mounting region for fixing the attachment. A coupling unit assigned to the upper link is movable in a translatory manner in a vertical direction running perpendicular to a transverse direction. The coupling units are movably disposed on a device base of the coupling device, and the coupling units assigned to the two lower links are movable in a translatory manner in the transverse direction.
