Benjamin Leroy Holt was an American businessman and inventor who patented and manufactured the first practical crawler-type tread tractor. The continuous-type track is used for heavy agricultural and engineering vehicles to spread the weight over a large area to prevent the vehicle from sinking into soft ground. He founded with his brothers the Holt Manufacturing Company.
Marshall, Sons & Co. was a British agricultural machinery manufacturer founded in 1848. The company was based in the Britannia Iron Works, Gainsborough, Lincolnshire. Early production was of steam engines and agricultural machinery. Later production included diesel tractors such as the Field Marshall, Track Marshall and former Leyland wheeled tractors.
Ruston & Hornsby was an industrial equipment manufacturer in Lincoln, England founded in 1918. The company is best known as a manufacturer of narrow and standard gauge diesel locomotives and also of steam shovels. Other products included cars, steam locomotives and a range of internal combustion engines, and later gas turbines. It is now a subsidiary of Siemens.
The Case Corporation was a manufacturer of agricultural machinery and construction equipment. Founded, in 1842, by Jerome Increase Case as the J. I. Case Threshing Machine Company, it operated under that name for most of a century. For another 66 years it was the J. I. Case Company, and was often called simply Case. In the late 19th century, Case was one of America's largest builders of steam engines, producing self-propelled portable engines, traction engines and steam tractors. It was a major producer of threshing machines and other harvesting equipment. The company also produced various machinery for the U.S. military. In the 20th century, Case was among the ten largest builders of farm tractors for many years. In the 1950s its construction equipment line became its primary focus, with agricultural business second.
The development of tanks in World War I was a response to the stalemate that developed on the Western Front. Although vehicles that incorporated the basic principles of the tank had been projected in the decade or so before the War, it was the alarmingly heavy casualties of the start of its trench warfare that stimulated development. Research took place in both Great Britain and France, with Germany only belatedly following the Allies' lead.
Richard Hornsby & Sons was an engine and machinery manufacturer in Grantham, Lincolnshire, England from 1828 until 1918. The company was a pioneer in the manufacture of the oil engine developed by Herbert Akroyd Stuart, which was marketed under the Hornsby-Akroyd name. The company developed an early track system for vehicles, selling the patent to Holt & Co. in America. In 1918, Richard Hornsby & Sons became a subsidiary of the neighbouring engineering firm Rustons of Lincoln, to create Ruston & Hornsby.
Sir William Ashbee Tritton, JP, was a British expert in agricultural machinery, and was directly involved, together with Major Walter Gordon Wilson, in the development of the tank. Early in World War I he was asked to produce tractors for moving heavy howitzers, the result being eventually the first tanks.
The Advance-Rumely Company of La Porte, Indiana was an American pioneering producer of many types of agricultural machinery, most notably threshing machines and large tractors. Started in 1853 manufacturing threshers and later moved on to steam engines. Allis-Chalmers Manufacturing Co. purchased Advance-Rumley in 1931. The company's main works would become what was later known as the "La Porte plant".
The Avery Company, founded by Robert Hanneman Avery, was an American farm tractor manufacturer famed for its undermounted engine which resembled a railroad engine more than a conventional farm steam engine. Avery founded the farm implement business after the Civil War. His company built a large line of products, including steam engines, beginning in 1891. The company started with a return flue design and later adapted the undermount style, including a bulldog design on the smokebox door. Their design was well received by farmers in central Illinois. They expanded their market nationwide and overseas until the 1920s, when they failed to innovate and the company faltered. They manufactured trucks for a period of time, and then automobiles. until they finally succumbed to an agricultural crisis and the Depression.
A portable engine is an engine, either a steam engine or an internal combustion engine, that sits in one place while operating, but is portable and thus can be easily moved from one work site to another. Mounted on wheels or skids, it is either towed to the work site or moves there via self-propulsion.
Clayton & Shuttleworth was an engineering company located at Stamp End Works, Lincoln, Lincolnshire, England. The company was established in 1842 when Nathaniel Clayton (1811–1890) formed a partnership with his brother-in-law, Joseph Shuttleworth (1819–83).
Ruston, Proctor and Company was established in Lincoln, England in 1857, and were manufacturers of steam tractors and engines. They later became Rustons and then Ruston & Hornsby.
The Holt Manufacturing Company began with the 1883 founding of Stockton Wheel Service in Stockton, California, United States. Benjamin Holt, later credited with patenting the first workable crawler ("caterpillar") tractor design, incorporated the Holt Manufacturing Company in 1892. Holt Manufacturing Company was the first company to successfully manufacture a continuous track tractor By the early 20th century, Holt Manufacturing Company was the leading manufacturer of combine harvesters in the US, and the leading California-based manufacturer of steam traction engines.
Bramah Joseph Diplock was an English inventor who invented the pedrail wheel in 1899 and the pedrail chaintrack, a type of caterpillar track, in 1907.
Robey and Co. was an engineering company based in Lincoln, Lincolnshire, England which can be traced back to around 1849.
The Foster-Daimler tractor, often called the Daimler-Foster tractor, was a heavy tractor built by William Foster & Co. in the early 20th century. It was used by the armed forces of the United Kingdom as a heavy artillery tractor during the First World War, it also formed the basis of the experimental Tritton trenching machine and its power unit was used in early British tanks.
