  • Publication number: 20100308559
    Abstract: The invention relates to a device for supplying electricity to an agricultural utility vehicle (10) and/or an attachment (26) which can be coupled to the utility vehicle (10). The utility vehicle (10) comprises a generator (16) and an attachment interface (24). Electrical energy can be generated by means of the generator (16). At the attachment interface (24) an attachment (26) can be reversibly coupled to the utility vehicle (10). The attachment (26) has at least one electrical load by means of which an agricultural working function can be carried out. So that the attachment (26) can be controlled more flexibly or better when it is operating, the device according to the invention is defined by a transmission device and at least one transformer (40). By means of the transmission device the electrical energy which is generated by the generator (16) of the utility vehicle (10) can be transmitted in the form of alternating voltage to the attachment (26). The transformer (40) is provided on the attachment (26).
