About Farmall Tractors
The McCormick Harvesting Machine Company, formed by Cyrus Hall McCormick, merged with several other manufacturers and formed the International Harvester Co. They were primarily known for the production of harvesting equipment. They began experimenting with tractors around 1905. These tractors were huge, powerful and clumsy and although they were useful for large areas, they did not work well for the small acreage farmer.

Their first attempt at a smaller tractor was the Mogul 8-16 and was a big hit. International Harvester continued to refine their small tractor line with several follow-on models. The famous letter series tractors, including the A, B, H and M began production in 1939.

IH produced many tractors during their reign and were ranked as one of the largest manufacturers of farm tractors. In 1984 IH was purchased by Tenneco and merged with the Case Corporation.
