Determine the value of a new or used tractor by searching the tractor's make and model at TractorBlueBook.com and IronSearch.com, as of 2015. These websites provide value and appraisal information on agricultural and industrial equipment.
TractorBlueBook.com allows users to search for a tractor by make, model and year. However, the site requires a subscription to see actual tractor values instead of estimates. Tractor Blue Book also provides values and appraisal information on utility and grounds maintenance vehicles.
IronSearch.com provides prices and purchasing information for a variety of heavy-duty vehicles, including harvesters, balers, mowers and combines. Iron Search also provides consumer reports on tractor manufacturers that include John Deere, Kubota, Massey-Ferguson and Case.
