Super A Farmall Tractor Specifications


The Farmall Super A tractor was produced by International Harvester between 1947 and 1954. The Super A models were general-purpose, durable tractors built for strength and versatility, making them well suited for small farming tasks. The Super As had the same engine as the earlier Farmall models F-12 and F-13, yet the Super A engine was positioned to the left of the operator's seat. Approximately 107,000 Farmall Super A models were produced, and they've become a collectors' item for farming enthusiasts.
