Before the first tractor invention, farmers relied primarily on horses and bulls to do labor-intensive tasks. The appearance of steam power in the 19th century provided a more efficient and powerful alternative for agricultural work.
Steam Tractors
In 1812, Richard Trevithick built a semi-portable steam engine called the Barn Engine, which was mainly used for operating machines that separated grain from corn. He was a pioneer in developing steam-powered tractors.
In 1839, William Tuxford started the production of a truly portable engine built around a locomotive-style boiler.
Later, British engineer Thomas Aveling built the first real traction engine in 1859. He modified a Clayton & Shuttleworth portable engine and made it self-propelled. This was done by adding a long chain that linked the crankshaft to the rear axle.
The picture below is thought to be a photo of Aveling’s first traction engine. It shows the chain connecting the rear wheels to the crankshaft, with no steering mechanism in place yet.

This innovation transformed the agricultural industry and defined the future of tractors. From that moment farmers could cover larger areas more quickly and with less physical effort.
Gasoline Tractors
As time passed, farmers and inventors saw the need for a more practical option. The shift from steam power to internal combustion engines began in the early 1900s with the gasoline tractor invention.
John Charter built the first gasoline-powered tractor in 1889. He combined single-cylinder Otto engines with a Rumley steam engine chassis. His Charter Gas Engine Co. was the first tractor brand.
In 1892, John Froelich also built a gasoline-powered tractor. He was the first American tractor inventor, whose machine helped US farmers provide food to the population.
John Froelich attached a single-cylinder gasoline engine to the chassis and used his gearbox to control and drive it. After securing a patent, Froelich founded the Waterloo Gasoline Engine Company and invested all his resources into this venture. Unfortunately, it was unsuccessful, and by 1895, Froelich had lost everything and went out of business.
By 1903, Charles W. Hart and Charles H. Parr successfully built the first American tractor equipped with a two-cylinder gasoline engine named the “Old Number Oneโ, Serial No. 1205. The Hart-Parr No. 1 tractor was used by its first owner for five years starting in 1901. Then it changed owners several times over the next 12 years before being disposed of shortly after World War I.
This 14,000-pound tractor only had about 30 horsepower but was more efficient and easier to operate. Today this oldest surviving internal combustion engine tractor is on display at the Smithsonian National Museum of American History in Washington, D.C.
Notably, the term “tractor” was first introduced by the Hart-Parr company.
