A sketch of a Farmall Tractor at a local nursery. Farmall was a model name and later a brand name for tractors manufactured by the American company International Harvester. Farmalls were general-purpose tractors. Their origins were as row-crop tractors, a category that they helped establish and in which they long held a large market share. During the decades of Farmall production (1920s to 1970s), most Farmalls were built for row-crop work. Most Farmalls were all-purpose tractors that were affordable for small to medium-sized family farms and could do enough of the tasks needed on the farm that the need for hired hands was reduced and the need for horses or mules was eliminated.
