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.
Early tractor designs were based on the concept of substituting mechanical pulling or draft power for the draft animal classically associated with pulling plows through the soil, operating reaper and binder machines through fields of corn, or mowers through fields of grass. Cumbersome steam powered engines were soon to be replaced by the more energy efficient and compact internal combustion engine.
