The McCormick-Deering O-12 was built by International Harvester from 1934 to 1938 in the Chicago, Illinois Tractor Works factory, USA.
Model history[]
The McCormick-Deering O-12 was very similar to the W-12 but had some different features to adapt it to working in orchards. The engine was governed at 2,000 rpm for a little more power. Orchard fenders and low-mounted air intake and exhaust protected low-hanging limbs and fruit. Rubber tires were standard and small-diameter wheels reduced the overall height.
