The Farmall 400: the best-kept secret of the Farmall line

The tractor is a fantastic value in the 40 to 50 horsepower class

Here’s the secret: the Farmall 400 is nothing more than a Super M-TA with fancier tin. The Farmall M is one of my all-time favorite tractors and the Super version of the Farmall M is even more powerful. The torque amplifier adds another layer of power, making the Super M-TA one of the more sought-after tractors in its class. This popularity is for good reason!

In 1954, International Harvester decided to rebrand their product line, switching from letter designations to numbers. I understand their desire for a name change – after adding “Super” and “-TA” to the model designation, they really couldn’t do much more to indicate new features. The entire product line was given new designations and the Super M-TA resurfaced as the 400.



 

In every important area, the Farmall 400 is the same as the Super M-TA. The tractors share the incredibly reliable and easy to maintain 4.3L 4 cylinder engine, offered in gasoline, diesel and LP gas. The Farmall 400 came with optional power steering. There’s no three-point hitch offered from the factory but many tractors come with the two-point IH Fast Hitch.

More than 40,000 of these tractors were produced over three years at the Rock Island, Illinois factory. This number may seem low until you remember that the 400 shares almost all parts with the Super M (50,000+ produced) and many parts with the M (270,000+ produced). The laws of supply and demand are on your side!

This tractor is a great buy. It’s as much as US$4,000 less expensive than the Super M-TA. As long as you don’t have a nostalgic connection to the letter designation on the hood, buy the 400. You get all the same benefits as the Super M-TA with a much lower price tag.

The 400 is only the same as a SMTA in terms of the power train. It had a completely new and different hydraulic system, the “Hydra-Touch” live system with 3 remotes. It’s actually extremely useful compared to other systems of the time and is essentially loader ready from the factory.

Based on Rachel Gingell's sound advice, I bought one this summer -- for $900. Very good machine. Put an F-25 Farmhand loader on it and am feeding cows with it daily. Basically doing the same thing with this that a lot of guys are doing with $1000,000+ FWA machines, and smiling from ear to ear!

Thanks Rachel for your insight on the features, advantages and benefits of the 400. I own a SMTA and have considered purchasing a 400 with power sterring. Keep up the good work! Cary
