Abstract

A harvest header for a harvesting machine includes a carrying frame, a mechanism for receiving or cutting harvest material from a field, a control device, a power-operated actuator operably controlled by the control device, and a transverse conveyor screw movably controlled between two or more positions. The position of the transverse conveyor screw is adjustably controlled by the actuator in order to transport the harvest material to a discharge opening. The control device independently controls the actuator based on at least one harvest material property.
