nternational Harvester was an American corporation based in Chicago that produced a multitude of agricultural machinery and vehicles. It was the result of a 1902 merger between the McCormick Harvesting Machine Company and Deering Harvester Company, along with three smaller agricultural equipment firms: Milwaukee; Plano; and Warder, Bushnell, and Glessner (manufacturers of Champion brand). International Harvester remained in business until 1985. edit this text
