Control system to automatically center an agricultural harvester header

A control system for an agricultural harvester having a frame and a header, the header being attached via a feeder adapter to a feeder housing which connects the header to, and supports the header from, the harvester, a position of the feeder adapter being adjustable relative to the frame of the harvester, the control system comprising:

• a header tilt control module that operates to level the header relative to the frame of the harvester, wherein said header tilt control module operates to automatically level the feeder adapter to the harvester when the feeder housing is located above a predetermined height and the header is operated manually when the feeder housing is located below said predetermined height;
• a feeder housing limit switch located to power said header tilt control module to indicate said automatic leveling operation when the feeder is raised;
• a self centering sensor located on the feeder adapter that indicates a self-centering signal corresponding to a position of the header relative to the frame of the harvester;
• and
• a balance resister that indicates a fixed balance signal corresponding to the header being level relative to the frame of the harvester;
• a mode switch for selecting at least one mode of operation regarding control of the header, said at least one mode implementing both said manual operation and said automatic leveling of the header;
• wherein said header tilt control module is electrically connected to said self centering sensor and said balance sensor to compare said self-centering signal to said balance signal, and controls a position of the header to level the header relative to the frame of the harvester based upon said comparison.
