How do you find the model of a Ford tractor using the serial number?

Ford tractor models can be identified using the prefix, the first number and letters, of the serial number. For example, the serial number for many Ford tractors will begin with an 8N or 9N starting combination, which is the model type of the tractor.

Serial number cross reference guides for most models, as well as photos, are available online at websites such as MyFordTractors.com, Ford8n.com, OldFordTractors.com and SpringfieldBiz.com. Make sure that the serial number used for identification is the tractor number on the frame and not the engine serial number on the engine block. Many models of engines fit in a variety of tractor models, so make sure the correct number is used for the intended purpose.
