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.

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.Swinford 1996, p. 22 39,499 CAs were produced at West Allis until 1958, with a 1958 price of about $1,900.
