IHC

International Harvester Company (IHC) was a historic American manufacturer known for producing durable trucks, agricultural machinery, and construction equipment. Founded in 1902 through the merger of several agricultural equipment companies, IHC quickly became a trusted name in both the farming and trucking industries. Its International®-branded trucks were widely used for commercial, military, and industrial applications throughout the 20th century. While the company reorganized as Navistar International in the 1980s, many IHC vehicles and components remain in use today, supported by a robust aftermarket for parts and service.
