Sugarcane harvester billet discharge control

A sugarcane harvester comprising:

• a base cutter configured to cut sugarcane;
• a chopping device in communication with the base cutter to receive the sugarcane cut by the base cutter, the chopping device configured to chop the cut sugarcane into billets;
• an elevator in communication with the chopping device, the elevator configured to transport the billets out of the sugarcane harvester, the elevator having a discharge end;
• a billet deflector movable relative to the discharge end to guide flow of billets from the discharge end;
• a powered actuator coupled to the billet deflector to move the billet deflector relative to the discharge end;
• and
• a controller to receive fill signals indicating a fill characteristic of a volume receiving the billets discharged by the elevator, the controller configured to output control signals to the powered actuator to control a discharge direction of the billets based upon the fill signals.
