The first tractors were built around 1885. They were steam powered and most of all looked like locomotives without rails. In 1892, an American blacksmith named John Froehlich constructed the first tractor using kerosene as its fuel. He used the vehicle to power a thrasher.
These early tractors were extremely heavy. That was a problem because the wheels got stuck in the muddy fields or they ruined the soil by pressurizing it too much. In 1904, the American Benjamin Holt built a tractor that used caterpillar tracks instead of wheels. This way, the weight of the tractor was distributed on a larger surface. Benjamin Holt named the tracks "caterpillars" and later used the same word as the name for the company he established. Today, Caterpillar is one of the world's leading manufacturers of construction equipment.

Henry Ford, who made cars available to ordinary people by having them produced on assembly lines also contributed to giving the tractor a breakthrough. As early as in 1907, one of Ford's engineers developed a tractor, but it was not until 1917 that it was put into mass-production. The Fordson tractor, as it was called, was sold by the millions in both the USA and in Europe.
The Irish inventor, Harry Ferguson, was the one to give the tractor its modern design. In 1916, he had the idea to make the engine block a central part of the tractor's construction whereby the distribution of weight was significantly improved as was the general stability. Ferguson and the engineers employed by him also invented mechanisms to transfer power from the tractor to implements that were hooked up to it.
Finally, in 1932 Ferguson manufactured the first tractor that featured much larger back wheels than front wheels whereby the tractor became a much safer vehicle to drive. Before that, serious accidents would often happen because the tractor would tip over if the plow hit a large stone in the ground.
In Europe, the tractor won its breakthrough right after the Second World War. As late as in 1939, England still had over one million horses used predominantly for pulling the plow. 11 years later, in 1950, there were only about 50,000 such horses left.
