The Avery Company, founded by Robert Hanneman Avery, was an American farm tractor manufacturer famed for its undermounted engine which resembled a railroad engine more than a conventional farm steam engine. Avery founded the farm implement business after the Civil War. His company built a large line of products, including steam engines, beginning in 1891. The company started with a return flue design and later adapted the undermount style, including a bulldog design on the smokebox door. Their design was well received by farmers in central Illinois. They expanded their market nationwide and overseas until the 1920s, when they failed to innovate and the company faltered. They manufactured trucks for a period of time, and then automobiles. until they finally succumbed to an agricultural crisis and the Depression.
