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 just introduced to agriculture in 1932.^[1][2] A successful model at the historical height of row-crop tractor demand, the WC was the best-selling tractor model that Allis-Chalmers ever built.

The WC was the Model W variant tailored to cultivating, thus the W + C (for "cultivating") name. Other W variants, such as the WD and WF, followed later (in lower numbers).

The WC was popular in the Great Depression for its good value, affordable price, and frugal design elements. Two factors that lowered its cost of manufacture, and thus its sales price,^[2] were that it was made partially from off-the-shelf components, and that its steel channel iron frame eliminated the need for large, heavy castings for the transmission and rear end (as were often used in tractors of the era). Its power was ample for the time and class, allowing it to pull a two-bottom plow.
