Unloading arrangement for agricultural harvesting vehicles

A transport vehicle arrangement for use in an unloading arrangement with an agricultural harvester vehicle, comprising:

• 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 harvester information relating at least to a speed and direction of an agricultural harvester vehicle;
• and
• an electrical processing circuit coupled with the sensor arrangement and the wireless receiver, the electrical processing circuit being configured for steering the transport vehicle arrangement in a reverse direction such that the transport implement is positioned at a desired position relative to an unloading conveyance of the agricultural harvester vehicle, based upon the sensed angular orientation of the transport implement and the harvester information.
