The Official Tractor Blue Book contains an immense range of information covering not only the suggested used tractor prices, but also the approximate cost of the tractors when they were new. It includes loan values, statistics, options, features, and serial numbers of the various implements. It also lists virtually every tractor manufactured between the late 1930s and the present time. The book is available at most online booksellers for under $20 USD.
However, there are many other methods of locating, contrasting, and comparing used tractor prices. Used tractors are prevalent on ebay and Craigslist, and a number of websites are devoted solely to the buying selling of used tractors. Some of the more popular sites include tractorhouse.com, ironsearch.com, and tractorswapper.com.
The top ten agricultural producing states are California, Texas, Iowa, Nebraska, Minnesota, Kansas, Illinois, Wisconsin, North Carolina, and Indiana. It makes sense that the states with the most tractors will have the most used tractors for sale. Following the laws of supply and demand, the more similar items for sale, the lower the prices.
Sometimes, attending farm auctions will result in a discovery of the prevailing trends in used tractor prices. For most people, the best route to uncovering accurate used tractor prices is to engage in extensive research before making a purchase.
