System and method of assisted or automated grain unload synchronization

A system comprising:

• An agricultural harvester including—
• a crop processor for separating grain from material other than grain,
• a grain tank for storing clean grain,
• an unload conveyor for transferring a stream of processed crop out of the harvester, and
• an electromagnetic detecting and ranging module positioned at or above a top of the grain tank for detecting a fill level of the grain tank and the location of a receiving vehicle relative to the combine harvester;
• and
• one or more computing devices for—
• receiving data from the electromagnetic detecting and ranging module, the data indicating the fill level of the grain tank and the location of the receiving vehicle relative to the combine harvester,
• using the data to generate graphic data defining a graphical representation illustrating the relative positions of the unload conveyor and a grain bin of the receiving vehicle;
• and
• an electronic device including a graphical user interface, the electronic device configured to use the graphic data to present the graphical representation on the graphical user interface.
