International Harvester (IH) tractor serial number tables are the primary tool for identifying a machine's production year and origin, crucial for both collectors and maintenance . These tables typically list the starting serial number

for each model year, allowing you to match the number stamped on your tractor's identification plate to its "birthday". Antique Tractor Blog How to Use Serial Number Tables

To accurately use these tables, you must first locate and decode the physical tag on your tractor: Locating the Tag : Plates are commonly found on the right side of the steering gear housing, the

of the transmission housing, or the seat support, depending on the model. The Kind/Code Format

: Modern IH tags (post-1960s) use a "Kind/Code" system. For example, a tag reading 2590009U004452 breaks down into: Kind (259) : The machine type. Code (009) : Specific configuration. Country (U) : "U" for United States. Serial Number (4452)

: The actual production sequence number to look up in the table. Suffix Letters International Harvester Tractor Serial Number Table-

: Some numbers end in letters (e.g., "J") which indicate special features like a Rockford clutch. Octane Press Expert Tips for Identification

When tables alone aren't enough (e.g., a missing or damaged tag), experts recommend these secondary methods: Casting Date Codes

: IH stamped date codes on major components like the engine block or transmission case. These codes use a letter to represent the year (starting with "A" for 1931). Engine Serial Numbers

: Often stamped on a machined flat surface of the cylinder block, these numbers usually trend slightly higher than the tractor's chassis serial number but can confirm the age. Regional Differences

: Australian-made IH tractors used square-cornered tags, whereas USA-made versions featured rounded corners. Antique Tractor Blog Top Resources & Registries Wisconsin Historical Society IH Archives

This is where IH competed directly with Deere's New Generation. The serial number tags are usually rectangular aluminum plates.

Note: The famous 1066 is the most collected. Serial numbers 501 to 5,000 (1971) are considered early "blue ribbon" tractors. Numbers above 50,000 are 1975-1976 models. This is where IH competed directly with Deere's

This was IH’s first modern row-crop tractor with a V-8 diesel option. The serial number table shows a critical split in 1965:

Unlike modern vehicles with VINs located in standardized spots, older tractors can be tricky. International Harvester placed serial numbers in a few specific locations depending on the era and model.

1. The Serial Number Plate (Tag) For most tractors, look for a thin metal plate riveted to the instrument panel (dashboard) or the side of the clutch housing. This plate usually lists the Model, Serial Number, and sometimes the Speed Ratio.

2. The Engine Block On older models (like the Letter Series), the serial number is often stamped directly into a boss (a flat, raised surface) on the engine block, typically on the left side near the carburetor or magneto.

3. The Casting Codes If the tag is missing and the engine pad is rusty or ground down, you can estimate the age using casting codes. IH cast dates into their parts (blocks, heads, housings) using a letter-number code.
