The Allis-Chalmers Model C was a small row-crop tractor manufactured by
Allis-Chalmers from 1940 to 1949. It was developed from the smaller
Allis-Chalmers Model B.
Description and production
The Model B was too small to work two crop rows at once. Allis-Chalmers briefly adapted the
Allis-Chalmers Model WC
The Model WC was a tractor made by Allis-Chalmers from 1933 to 1948. The WC was designed from its start as a nimble, low-cost, but well-powered row-crop tractor that would make the best use of pneumatic rubber tires, which Allis-Chalmers had j ...
as the RC from 1938 to 1941, but it proved expensive, so the B was adapted with wider wheel spacing options, a larger engine, and additional fuel options. The Model C used the RC's Allis-Chalmers 4-cylinder engine, with gasoline and
distillate fuel options. The C inherited the B's three-speed transmission,

84,020 Model Cs were built at the Allis-Chalmers plant in
West Allis, Wisconsin. In 1949 a Model C sold for about $1,200.
Model CA
Starting in 1949, the Model C was replaced by the Model CA, with greater power, allowing it to be rated as a two-plow tractor. The engine remained the same, but turned at a higher RPM and had a higher degree or compression, yielding 11 percent more power. It was provided with a new four-speed transmission, and power assist rear wheel adjustment was introduced. The CA was produced with single and narrow dual wheel front ends, and an adjustable wide front axle.

39,499 CAs were produced at West Allis until 1958, with a 1958 price of about $1,900.
