Abstract: A data communication interface for an agricultural utility vehicle, particularly an agricultural tractor, having an interface connector that can be connected either to a first data communication network or to a second data communication network by means of an electrically operatable changeover device, wherein the first data communication network is terminated at a line end associated with the interface connector by means of a disconnectable terminating resistor, and having a control unit that connects the interface connector to the first data communication network by means of appropriate operating of the changeover device exclusively when it infers the presence of a control signal that is provided for disconnecting the terminating resistor.

Abstract: A method for regenerating a particulate filter of an internal combustion engine. The method includes passing an exhaust gas stream through the particulate filter, determining what kind of fuel is being combusted in the internal combustion engine, and determining a burn-off temperature that is capable of burning off a kind of soot formed in the particulate filter as a result of the combustion of the kind of fuel. The burn-off temperature is based on the kind of fuel.

Abstract: The present invention is directed to a device for steering a second agricultural machine which can be steered over a field relative to a first agricultural machine. The device includes a distance meter mounted on one of the machines and operable for recording measured values with regard to direction and distance of objects adjacent to the distance meter over a horizontal region. The device also includes an evaluating means which is connected to the distance meter and is designed to output a steering signal for causing guidance of the second machine relative to the first machine on the basis of the measured values of the distance meter.
