The McCormick-Deering W-12 was built by International Harvester from 1934 to 1938 in the Chicago, Illinois Tractor Works factory, USA.

Model history[edit | edit source]

The McCormick-Deering W-12 was a small standard tread tractor powered by the basic 113 ci 4-cylinder engine from the Farmall F-12. The W-12 was slightly more powerful than the F-12 because the governed engine speed was increased from 1400 to 1700 rpm.
