The McCormick-Deering W-4 was built by International Harvester from 1940 to 1953 in Rock Island, Illinois, USA.

Model History Edit

For Company history see
Main article: International Harvester

International Harvester introduced a new styled W-series of standard 4-wheel tractors in 1940. Production was slow getting started so the older unstyled W-series was continued through the year as well. The new W-4 eventually took the place of the old 10-20.

The W-4 used the same 152 ci ohv 4-cylinder gasoline engine and 5-speed transmission as the Farmall H. However, the standard-tread W-4 had a unit frame instead of the straight frame on the H row-crop model. The W-4 was available with steel wheels but most tractors were equipped with rubber tires. The rated power output was 24 belt hp and 21 drawbar hp. See Nebraska test results for gasoline engine below.

Only 213 W-4s were built in 1940 but full production in 1941 turned out 3,554 tractors, making the W-4 the best seller in this class. In 1940 the W-4 competed with the John Deere AR, Oliver 70 Standard, and Case S. The Graham-Bradley 104, Massey-Harris 101 Junior Standard, and Minneapolis-Moline ZTS all had a bit more power. By the late 1940s the John Deere BR and Minneapolis-Moline RTS had grown in power to where they equaled the W-4, and the Massey-Harris MH-30 and Oliver 77 were more powerful.

The W-4 was named McCormick-Deering through about 1945. After that the name was shortened to just McCormick. However, restored tractors may have either decal.
