Farmall M History

Between 1939 and 1953, International Harvester was the first company to make the Farmall M tractor.

Still, it is thought to be one of the best tractors ever made. It was made to be powerful, strong, and flexible, which made it a great tool for farming in the 21st century.

Out of the total number of tractors made, 57,092 were made.

Over time, it has changed and improved a lot. For example, the engine has been upgraded, and it now has power steering and other new features. Today, it is called the Case IH Farmall Super M tractor.
