ABSTRACT:
A self-propelled axial flow combine having a crop harvesting header for supplying crop material to a longitudinally oriented rotor power-rotated within a generally cylindrical casing. The casing includes a grate through which crop material is impelled at high speed by the rotor. The combine includes a grain cleaning system having a chaffer sieve reciprocably mounted to receive crop material from the grate for sifting the material as a part of the cleaning process. Crop sensors are mounted on the chaffer sieve to sense material flow from the grate. In addition, crop sensors are mounted at the rear of the chaffer sieve for sensing crop losses from the sieve.
