Abstract
An agricultural combine (100) has a windrow control circuit that controls the profile of windrow (154) based upon signals received from a sensor (152).
Claims16
An agricultural combine (100) having a windrow control circuit, comprising:
- a self-propelled harvesting vehicle (102) configured to harvest crops, separate grain from material other than grain, and deposit material other than grain 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 material other than grain 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 material other than grain leaving the self-propelled harvesting vehicle (102);
- and
- at least one electronic control unit (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 electronic control unit (192) is configured to receive data indicative of a profile of the windrow (154) from the sensor (152), wherein the at least one electronic control unit (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 electronic control unit (192) is configured to drive the at least one actuator (160, 172, 178, 166, 190, 184) in response to the comparison.

In an agricultural combine (100) configured to make a windrow and having a windrow control circuit comprising at least one steering vane for directing a flow of material other than grain leaving the agricultural combine (100), a method of controlling a windrow profile comprising steps of:
- electronically generating electronic data indicative of a profile of the windrow;
- electronically extracting at least one parameter indicative of the profile of the windrow;
- electronically comparing the at least one parameter indicative of the profile of the windrow with at least one parameter defining a reference windrow profile;
- and
- electronically controlling an actuator coupled to the at least one steering vane based upon results from the step of electronically comparing.
