The John Deere Model A came off the assembly line in April 1934. The tractor was , was , and had a four-speed transmission. There were eight different model A variations. Some of these were tricycle, hi-crop, orchard, single front tire, and industrial models. The tricycle wheel design, patterned after that of the Farmall tractor, reduced steering effort, and greatly increased maneuverability. The Model B was introduced in June 1934. This tractor had a shorter frame than the Model A, but it was eventually lengthened so it could use some of the same equipment that the larger models A and G used. There were also eight different Model B tractor variations, the same as the larger Model A.
