Data

TractorData.com
Model specifications, production years, engines, transmissions, dimensions, serial numbers and literature references for nearly every model. Each model page links to its TractorData.com page. We don’t copy or reuse images from TractorData.com.
Nebraska Tractor Test Laboratory, University of Nebraska–Lincoln
Independent test results (PTO and drawbar power, fuel use, maximum pull), where a model was tested. Test results on model pages link to the published report where one is available.

Hand corrections to individual values are listed on the model’s page, each with the source of the corrected value. Spotted something wrong? Corrections with a source are very welcome.
