BUTCH'S ALLIS CHALMERS
1929 ALLIS CHALMERS U
The "U" was A-C's answer to the Ford's Fordson tractor and was first produced in 1929 in partnership with the United Tractor Company. It was popular enough that it stayed in the A-C line until 1952. It weighed 4,000 pounds and produced up to 30 HP, particularly later in its production run. The "U" also had the distinction of being the first farm tractor equipped by the manufacturer with low-pressure rubber tires.
