International Harvester Tractor Serial Number Table: A Collector’s Guide to Dating Your Red Iron

If you own a classic International Harvester (IH) tractor—whether a letter-series Farmall, a gassy old Cub, or a burly 1066—one of the first things you’ll want to do is pin down its birthday. Fortunately, IH kept meticulous records. Below is a simplified serial number table covering the most popular models from the 1930s through the early 1980s. 1947: 501 – 13439 1950: 73926 – 106486

Tip: The serial number is usually stamped on a flat plate or directly into the casting on the left-hand side of the clutch housing or transmission case.

6. Limitations & Accuracy

• No single master table exists for all IH tractors. Different factories (USA, UK, Germany, Australia) used independent serial ranges.
• Model year vs. calendar year: A tractor made in November 1955 is often sold as a 1956 model.
• Replacement plates: Some tractors have had plates replaced, leading to mismatched numbers.
• Official sources: The Wisconsin Historical Society (IH archives) and International Harvester Tractor Data Book (by Guy Fay) are the most authoritative references.
