The McCormick-Deering 10-20 Narrow Tread was built by International Harvester from 1926 to 1934 in the Chicago, Illinois, USA Tractor Works factory.

Model HistoryEdit

Eight of the McCormick-Deering 10-20 KC-series tractors were built in narrow tread configuration for work in closely planted orchards or vineyards in 1925. In 1926 this design turned into a separate NC-series of narrow tread tractors that were about a foot narrower than the regular 10-20.
