System and apparatus for providing driver pacing information for agricultural vehicles

A system comprising:

• a mobile machine configured to move across a ground surface and gather a material from a location adjacent to the ground surface and dispense the material from a dispensing structure of the machine at a raised location with respect to the ground surface, the dispensing structure being movable to change a trajectory of material exiting the dispensing structure;
• and
• a driver pacing information apparatus configured to provide a driver of a transport vehicle with pacing information for operating the transport vehicle alongside the mobile machine;
• wherein the dispensing structure of the mobile machine includes a transfer spout assembly with a transfer spout;
• and
• wherein the driver pacing information apparatus comprises:
• a position sensing assembly for sensing a position of the transfer spout with respect to the frame of the harvester;
• and
• a pacing indication display configured to provide pacing information in a sensibly-perceptible form to the driver of the transport vehicle moving along a path oriented substantially parallel to a path of the mobile machine;
• wherein the position sensing assembly comprises a position sensor in communication with the transfer spout to sense an angular value of the position of the transfer spout, the position sensor being configured to detect a first range of angular values and a second range of angular values, the first range of angular values being associated with an orientation of the spout for which a decrease in a speed of movement of the transport vehicle is indicated and the second range of angular values being associated with an orientation of the spout for which an increase in the speed of movement of the transport vehicle is indicated.
