Farmall H Technical and Background Information

International Harvester built the Farmall H from 1939 until 1953. The Farmall H was "an ideal, all-purpose tractor for diversified farms up to 160 acres, or for specialized farms raising such row crops as potatoes or sugar beets. It pulls two 14-inch bottoms, cultivates up to 35 acres of row crops a day, and speeds up other farm jobs in proportion." according to the sales literature of the time.
