International Harvester was an American manufacturer founded in 1902, known for producing agricultural machinery, trucks, and construction equipment. The company played a significant role in the development of farming technology, creating iconic products like tractors and combine harvesters that helped modernize agriculture. In 1985, International Harvester ceased production of agricultural equipment and shifted focus to its truck and engine divisions. The company eventually became part of Navistar International Corporation, which continues to produce commercial vehicles and engines, maintaining the legacy of innovation in the transportation and agricultural sectors.
