Abstract: An agricultural machine arrangement including at least one traction machine and at least one attachment device adapted to the traction machine, with a driver assistance system optimizing the operation of the traction machine and/or of the respective attachment device. The driver assistance system includes a computing unit and at least one display unit, wherein the computing unit processes information generated by machine-internal sensor systems, external information and information stored in the computing unit and wherein the traction machine and the attachment device include a control device for open-loop and closed-loop controlling the traction machine and/or of the attachment device.

Abstract: A method for the authentication of at least two agricultural devices coupled via a data bus includes subjecting the each of the agricultural devices to authentication, automatically and independently of every of the agricultural device by use of an authentication device, which is also coupled to the data bus. The method also includes allowing a direct data exchange or indirect data exchange between the successfully authenticated agricultural devices, automatically. If authentication of the at least two data devices is unsuccessful, data exchange between the unsuccessfully authenticated agricultural devices is disallowed.
