A case combine often referred to as a rotary harvester is a household name among farmers globally. They are suitable for harvesting various types of grains. Their initial manufacturer was International Harvester, but CNH Global, Case Corporation, and Case International later took over. One must admit that when their design saw the light of the day in 1977, it took the industry by a storm. The traditional design, which used straw walkers and drums, became unpopular.
