of this Ford with Ford Motor Company. The company built and sold some tractors, but anticipated a settlement with Henry Ford for permission to use their already-trademarked name. However, Ford thwarted them by using another name. Fordson origins, Model F, and Model N The first prototypes of the new Henry Ford & Son tractor, which would later be called the Fordson, were completed in 1916. World War I was raging in Europe, and the United Kingdom, a net importer of food, was desperate for tractors in its attempt to expand its agriculture enough to feed Britain despite the great shipping disruption of the war. In 1917, the British Ministry of Munitions selected the Fordson for both importation from the U.S. and domestic U.K. production. It was thought that domestic U.K. production was preferable because so much Atlantic shipping was being sunk that exporting tractors from the U.S. would be counterproductive, as many would be lost at sea. This was soon modified to exclude the London area because of concerns about its vulnerability to German attacks. Henry Ford decided to build the tractor at Cork, Ireland (which at the time was still part of the U.K.), partly because he wanted to bring jobs to, and foster industriousness in, southern Ireland. But the Cork plant did not begin production until 1919, after the war had ended. As events turned out, thousands of tractors were exported from the U.S. in 1917 and 1918. The tractor used a , inline four-cylinder engine. The engine was similar to the Ford Model T engine in many respects. Like many engines of its day, it was multifuel-capable; it was usually tuned for gasoline or kerosene, but alcohol could also be burned. (Tractor vaporising oil [TVO] existed in 1920 but was not yet widely used. It entered broader use in the 1930s and 1940s.) Like many other multifuel machines, the Fordson started on gasoline from a small auxiliary tank (just a few quarts) and then switched over to the main fuel tank once warmed up sufficiently (no more than 5 minutes). To handle the kerosene (or, rarely, TVO), the intake system had a vaporizer downstream of the carburetor. The mixture coming from the carburetor was intentionally rich, and the vaporizer heated it and mixed it with more air to lean it out to the final ratio before entering the inlet manifold. The intake system also had a water-bath
