A small tractor with 40 horsepower sells for about $6,000 to $15,000, while a tractor with 50 to 75 horsepower costs about $20,000 to $35,000, as of 2015. A large agricultural tractor with 95 to 120 horsepower sells for about $50,000 to $75,000.
Tractors with large amounts of use and wear sell for significantly less than newer ones. Loaders, rakes, backhoes and other attachments cost hundreds to thousands of dollars more, depending on the quality and usage. Before buying a used tractor, shoppers should consider buying a warranty to ensure that the used tractor is not faulty in any way.
