Case
USA • 137 Models
Founded in 1842 by Jerome Increase Case, the J. I. Case Threshing Machine Company emerged as a pioneering force in agricultural machinery during the 19th century. The company gained early prominence by manufacturing steam engines, including portable engines and traction engines, which were crucial for mechanizing agriculture and construction in the United States. Alongside its steam engine innovations, Case became a leading producer of threshing machines and harvesting equipment, establishing itself as a cornerstone of American agricultural mechanization. By the early 20th century, Case expanded into the tractor market, becoming one of the largest tractor manufacturers globally. The company's commitment to quality and innovation earned it a reputation for robust and reliable machinery, serving both agricultural and construction sectors. In the mid-20th century, Case shifted its primary focus to construction equipment while maintaining a strong presence in agriculture. A pivotal moment in its history occurred in the 1980s when Case was acquired by Tenneco, leading to the 1985 merger with International Harvester's agricultural equipment division. This merger resulted in the formation of Case IH, a powerhouse brand that combined the legacies of two iconic agricultural machinery manufacturers. The new entity continued to innovate, introducing advanced technologies and expanding its global footprint.
