But collectors who dream of finding a rare tractor at an auction are looking for a piece of history that's largely out of their reach. One such rare collectible vintage tractor model is the Waterloo Boy Model N. These aren't small thrift store finds, and you're unlikely to find one sitting in an old barn. In the early 1900s, the farm implement brand Deere and Company was struggling to compete in the expanding farm equipment sector. The Model N was the last tractor produced under the Deere and Company name before the John Deere brand was adopted. Almost 100 years later, these tractors are a lot less affordable — a restored Model N sold at an auction house in 2023 for $100,000.
