User interface control for metered grain discharge

A combine harvester comprising:

• a storage bin for storing harvested crop,
• an unload conveyor pivotable between a stowed position and a deployed position;
• a flow gate for regulating a flow of harvested material from the storage bin to the unload conveyor;
• a first sensor for detecting a position of the flow gate;
• a second sensor for detecting a position of the unload conveyor;
• one or more computing devices configured to enable a user interface for—
• receiving from an operator of the combine harvester a set point for the flow gate, an on/off indicator for the unload conveyor and an unload conveyor position indicator,
• presenting a graphic element depicting at least a portion of the combine harvester, the graphic element including a graphical depiction of the unload conveyor, and
• indicating, using only graphical variations of the graphical depiction of the unload conveyor, a position of the unload conveyor, an operating status of the unload conveyor, the set point of the flow gate and the position of the flow gate.
