A device for implement localization on an agricultural tractor includes a first tractor-side transponder and a second tractor-side transponder. The first tractor-side transponder includes a first transmission and reception region corresponding with a first mechanical implement interface located on the agricultural tractor, and the second tractor-side transponder includes a second transmission and reception region corresponding with a second mechanical implement interface located on the agricultural tractor. An implement-side transponder is in communication with the first and second tractor-side transponders. Each of the first and second tractor-side transponders transmits a separate position identifier to the implement-side transponder via one of the first or second transmission and reception region, and the position identifier is transmitted back to the respective first or second tractor-side transponder.
