An unloading arrangement includes and agricultural harvester and a transport vehicle arrangement. The agricultural harvester includes an unloading conveyance and a wireless transmitter for transmitting information relating at least to a speed and direction of the harvester. The transport vehicle arrangement includes a transport vehicle a transport implement coupled with the transport vehicle a sensor arrangement for establishing an angular orientation of the transport implement relative to the transport vehicle a wireless receiver for receiving the transmitted information from the harvester and an electrical processing circuit coupled with the sensor arrangement and the wireless receiver. The electrical processing circuit is configured for steering the transport vehicle arrangement in a reverse direction such that the transport implement is positioned at a desired position relative to the unloading conveyance, based upon the sensed angular orientation of the transport implement and the transmitted information received from the harvester.
