The International Harvester Company, also known as IH, was an American manufacturer of agricultural machinery, trucks, and other commercial vehicles. The International Harvester Company was formed in 1902 through a merger of several leading agricultural equipment manufacturers, including the McCormick Harvesting Machine Company, Deering Harvester Company, Plano Manufacturing Company, and several others. The merger created one of the largest manufacturers of agricultural machinery and equipment at the time.
One of International Harvester's notable contributions to the automotive industry was the introduction of the Scout, a compact SUV, in 1960. The Scout was designed to be a versatile and rugged vehicle capable of off-road adventures. It became a precursor to the modern SUV and gained popularity among outdoor enthusiasts.
In the 1980s, International Harvester faced financial challenges due to factors such as changing market conditions and labor disputes. To overcome these difficulties, the company underwent significant restructuring. In 1985, the agricultural division of International Harvester was sold off, and the company changed its name to Navistar International Corporation, focusing primarily on the production of commercial trucks and buses.
