    Farmall / International Harvester serial number questions

    Where is the Farmall / International Harvester serial plate?
    Check the clutch or transmission housing, the engine area, or the seat bracket on smaller Farmalls.
    How do I read a Farmall / International Harvester serial number?
    Copy the complete serial. FAA, FAB, FBH and FBK identify the A, B, H and M families. FC identifies the C family. SM and SML mark Super M tractors. Match the digits to the table for your exact model.
    How do I find the year of my Farmall / International Harvester tractor?
    Find the table for the exact model and series. Read down to the latest year whose starting serial is at or below yours. Where published lists disagree, check both tables.
    Which Farmall / International Harvester manual fits my machine?
    Start with the exact model and series, then compare your serial or build year to the range listed for each edition. Check any fuel, transmission or configuration details in the title.

    Sources

    Year and plate references are listed below. Manual coverage comes from the edition titles and serial ranges in The Manual Store catalog.
