Case IH 7140 rotary harvester with corn header with cutaway showing rotary threshing mechanism. Case IH axial-flow combines (also known as rotary harvesters) are a type of combine harvester that has been manufactured by International Harvester, and later Case International, Case Corporation, and CNH Global, used by farmers to harvest a wide range of grains around the world.
What happens next is dependent on the type of combine in question. In most modern combines, the grain is transported to the shoe by a set of 2, 3, or 4 (possibly more on the largest machines) augers, set parallel or semi-parallel to the rotor on axial mounted rotors and perpendicular on axial-flow combines.

Case IH history began when, in 1842, Jerome Case founded Racine Threshing Machine Works on the strength of his innovative thresher. In 1869 Case expanded into the steam engine business and, by 1886, Case was the world's largest manufacturer of steam engines.
In the axial compressor the air flows parallel to the axis of rotation. Axial compressors are made to be multi-staged. A stage consists of a row of rotating blades called the rotor, which are connected to the central shaft and a row of stationary or fixed blades called stator. In axial flow compressor, the air flows from stage to stage.
The Case Corporation was a manufacturer of agricultural machinery and construction equipment. Founded, in 1842, by Jerome Increase Case as the J. I. Case Threshing Machine Company, it operated under that name for most of a century. For another 66 years it was the J. I. Case Company, and was often called simply Case.
This machine, produced at East Moline, Illinois, was the first generation of over 30 years of Axial-Flow combines. In 1979 IH introduced two tractors, the 3388 and 3588, known as the 2+2 4WD line. These were built by taking two 1086 rear ends and hooking them together with a transfer case. A year later, the 3788 was introduced.
An animated simulation of an axial compressor. The static blades are the stators.. An axial compressor is a gas compressor that can continuously pressurize gases.It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially.
Forage harvesters can be implements attached to a tractor, [4] or they can be self-propelled units. In either configuration, they comprise a drum (cutterhead) or a flywheel [5] with a number of knives fixed to it that chops and blows the silage out of a chute of the harvester into a wagon that is either connected to the harvester or to another vehicle driving alongside.
