Agricultural combine with windrow control circuit

An agricultural combine (100) having a windrow control circuit, comprising:

• a self-propelled harvesting vehicle (102) configured to harvest crops, separate grain from MOG, and deposit MOG on ground in a windrow (154);
• a sensor (152) mounted on the self-propelled harvesting vehicle (102), wherein the sensor (152) is configured to sense a profile of the windrow (154);
• at least one steering vane (156, 168, 174, 162, 180, 186) disposed to deflect a flow of the MOG leaving the self-propelled harvesting vehicle (102);
• at least one actuator (160, 172, 178, 166, 190, 184) coupled to the at least one steering vane (156, 168, 174, 162, 180, 186) to move the at least one steering vane (156, 168, 174, 162, 180, 186) relative to the self-propelled harvesting vehicle (102) and deflect the flow of the MOG leaving the self-propelled harvesting vehicle (102);
• and
• at least one ECU (192) coupled to the sensor (152) and coupled to the at least one actuator (160, 172, 178, 166, 190, 184);
• wherein the at least one ECU (192) is configured to receive data indicative of a profile of the windrow (154) from the sensor (152), wherein the at least one ECU (192) is configured to perform a comparison of the data indicative of the profile of the windrow (154) and at least one parameter defining a reference windrow profile, and wherein the at least one ECU (192) is configured to drive the at least one actuator (160, 172, 178, 166, 190, 184) in response to the comparison.
