International Harvester was a prominent American manufacturer of agricultural machinery, construction equipment, trucks, and household appliances. Founded in 1902 through the merger of several companies, including the McCormick Harvesting Machine Company and the Deering Harvester Company, International Harvester played a vital role in shaping the agricultural and industrial landscape of the United States.

The company became known for its innovative farm equipment, such as tractors, combines, and plows, contributing significantly to the mechanization of agriculture. International Harvester also ventured into the production of trucks and construction equipment, solidifying its presence in various sectors. 

International Harvester went through significant changes over the years and ultimately evolved into a different entity. In 1985, International Harvester, facing financial difficulties and seeking to focus on its more profitable segments, sold the agricultural and construction equipment divisions to Tenneco Inc. In 1986, International Harvester rebranded the remaining portion of the company, primarily consisting of the truck and engine manufacturing divisions, as Navistar International Corporation.

Navistar continued to be a major player in the production of trucks, buses, and engines, while the agricultural and construction equipment divisions were no longer under the International Harvester umbrella. Over the subsequent years, Navistar faced various challenges, including financial struggles and legal issues related to engine technologies. In the early 2020s, Navistar agreed to be acquired by TRATON SE, a subsidiary of the Volkswagen Group, marking another chapter in the company’s history.
