A machine that can cut mature corn without shattering the ripe kernels at the top of its long slender stem, gather together and convey these stem heads-first into a threshing cylinder, where the bulk of the kernels are separated from the non-grain material by a combination of impact and sieving, and where the remaining separation is achieved by a combination of further sieving, flotation and vibration.
Apart from tractors, the agricultural equipment that has most caught the public imagination has been crop harvesters probably because of their (frequently massive) size, multiplicity of functions and bewildering variety of designs reflecting the huge variety in crop products and growth patterns whether the product to be harvested resides in the soil, above the soil surface, or on bushes or trees. Harvesting equipment is described in detail in Harvesters (EOLSS on-line, 2002).
