Identification Tool
Ford Tractor Model Decoder
Every digit in a Ford tractor model number means something. Enter the model code stamped above your serial number — from a three-digit 641 to a six-character C1023C — and see exactly what your tractor left Dearborn with.
Stamped on the transmission flat above/behind the starter, on the line above the serial number. Covers 1955–1975. (9N, 2N, 8N, and NAA tractors carried no model number — the serial prefix is the model.)
Decode tables compiled from Ford dealer reference charts for the Hundred Series (1955–57), '01 Workmaster/Powermaster Series (1957–62), and 1965–75 thousand-series tractors. 1962–64 five-digit codes were transitional and less standardized — the decoder reads what's well documented and says so where it isn't. Remember that hoods, badges, and even transmissions get swapped over 70 years: the stamped code tells you what the tractor was built as, not necessarily what's bolted to it today.
