The A was John Deere's first true row-crop tractor, replacing the GP. There were several variants of the A. The A was the row-crop model. The AR was a standard (or fixed) tread model. The AO was an orchard model, with no exhaust stack and shielded fenders. There was also the AI industrial model, the AN with narrow front, the AW wide front, and the high-crop ANH and AWH. The model A was the first Deere tractor to come from the factory with rubber tires.
