International Harverster's Farmall Cub was a little tractor with a big following during its production years of 1947-1964. Today more Cubs are found in parades and tractor shows than in fields and farmyards, but during its heyday more than 20,000 Farmall Cubs were the workhorses of small farms across the United States. The key to the year that a Farmall Cub was manufactured is the serial number on each tractor.

The year the tractor was built is easy to determine once the the serial number plate is located.

Find the serial number identification plate. This is a small aluminum plate easily visible near the front of the tractor engine on the right side near the gear housing. The original plate is about 3 inches by 4 inches.

All Farmall Cubs have individual serial numbers.

Write down the digit serial number stamped in the center section of the identification plate.

Compare the serial number to Farmall's list to find the year the tractor was manufactured (see References).

Things You'll Need:

  • Farmall Cub
  • Pen
  • Paper


If the serial number on you tractor is not listed it may be a Cub Lo Boy, manufactured from 1955 to 1968 or an International Cub, manufactured from 1964 to 1979.
