Allis-Chalmers Model C - Wikipedia
The Model B was too small to work two crop rows at once. Allis-Chalmers briefly adapted the Allis-Chalmers Model WC 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 125-cubic-inch (2,050 cc) Allis-Chalmers 4-cylinder engine, with gasoline and distillate fuel options. The C inherited the B's three-speed transmission, power take-off and hydraulics.
