Abstract
A method and apparatus for determining an area of crop being harvested by a harvesting machine having a cutter bar of a known total width. The method and apparatus includes a position determining system located on the harvesting machine, and a processor located on the harvesting machine. The processor is adapted to receive position signals from the position determining system and to determine a first position of the harvesting machine, determine a first effective cutter bar width, determine a second position of the harvesting machine, determine a second effective cutter bar width, and responsively determine an area of a polygon bounded by the first and second positions, and the first and second cutter bar widths.
