The Farmall BN tractor, built and designed by International Harvester, was part of a tractor series that was popularized during the 40s, according to TractorData.com. Manufactured from 1940 to 1947, the Farmall BN featured a 1.9L 4-cylinder gas engine that held 10 gallons of gas. The tractor boasted a 72.75-inch wheel base and weighed in at 1,800 ponds. It featured a narrower axle than International Harvester's Farmall B model.
The FarmallTractors.org explains that the Farmall tractor was first introduced to American farmers in 1923 and was manufactured by International Harvester. At the time, the newly designed piece of farm machinery was only released in Texas. Executives at International Harvester were not sure if the tractor's tricycle design would be well-received. However, despite initial uncertainties, the Farmall tractor sold well, and the manufacture of Farmall tractors began in Rock Island, Ill., in 1926.
In 1932, the Farmall tractor was equipped with a more powerful engine, which was utilized in the F-series designs. Tractor series A, B, BN, C, H, M and MD followed. However, the tricycle styling of the tractors remained as it offered quicker and more reliable steering.
Besides farming, International Harvester produced Farmall tractors for the mining, fishing and logging industries. According to FarmallTractors.org, the Farmall BN tractor's styling provided operators with enhanced visibility and added maneuverability in its design.
