User:B137/Allis CA
The Model CA was a row crop tractor made by Allis-Chalmers from 1950 to 1958. The CA had about 20 drawbar and 25 belt horsepower. It had a 4 cylinder gas engine and 13 gallon fuel capacity. The CA had a live PTO due to the hand clutch which disconnected the right side of the rear axle allowing the differential to spin freely. [1]
