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.
In 1977, International Harvester introduced the first Axial-Flow rotary combine. 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.
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.
