Allis-Chalmers WC, WF, RC
The Allis-Chalmers WC was a mid-sized tractor in the lineup, equipped with a 3.3-liter gasoline engine. It had 4+1 gears and a 10-inch clutch. The brakes functioned as steering brakes and were operated by hand levers. This required both hands to be removed from the steering wheel during braking. As an optional accessory, a mechanical lift was available, which took its power from the transmission shaft.
In 1938, the design was updated to a rounder style following model B. Electric starting and headlights were introduced. The rear wheels grew to 28 inches.
The WC became a success: a total of 178,000 units were produced. In some European countries, the WC was marketed under the name W.
Alongside the WC, a shorter, narrower, and lower WF was introduced in 1937. Its design was updated in 1940.
In 1938, the poorly performing RC model was introduced, which equipped the WC with the B's 2.1-liter engine. The gear ratios were slowed down compared to the WC. The RC was only available with wide front wheels. The RC was replaced by the Model C in 1941.
