John Scott

John Scott (c.1846–1909) was a Scottish consulting agriculturist, agricultural engineer, and pioneer of motorised farming. He is credited with the invention of the tractor power take-off.

Scott was the son of a farmer in Hawick, Selkirkshire, and as a young man farmed himself. He became Professor of Agricultureat the Royal Agricultural College, Cirencester, in 1880. He resigned his post to investigate ranching, in 1882. In 1877 James Macdonald had reported on American beef-raising for The Scotsman, and the topic had aroused much interest.

With John Chalmers Morton, the founding editor of the Agricultural Gazette, Scott wrote The Soil of the Farm (1882), in the "Handbooks of the Farm" Series. He then worked in agricultural journalism, first on the Farmer's Gazette (renamed in 1882), the long-running Dublin journal of W. S. and Edward Purdon. He later moved to the Scottish Agricultural Gazette, which became The Farming World, and was owned by James MacDonald. It was directed towards dairy farmers, and was merged to form The Scottish Farmer.

In 1886 Scott suffered sequestration in bankruptcy proceedings. At the end of 1888 he resigned from The Scottish Farmer to edit Sheep and Wool; its previous editor Charles Scott, his brother, joined the staff of the Melbourne Leader. Sheep and Wool reflected the interests of the trade, had been founded in July 1888 by Charles, and ran to April 1890 in its original form; it was owned by Scott & Co. In October 1888 Scott entered an agreement with Herbert Henry Cooper (died 1891) of Berkhamstead, one of the family of Richard Powell Cooper who inherited William Cooper & Nephews, the sheep dip business, in 1885.

In 1897 Scott took up development of a motor cultivator, showing one in 1899. The Motor Cultivator Syndicate, of Duddingston, Edinburgh, showed a cultivator in 1900. The Scott Motor Cultivator Ltd. was listed at 12 North St. Andrew Street, Edinburgh in 1903– 1905–6, 1906–7. Scott's Motor Cultivator was illustrated in a 1908 agricultural book.

Scott in 1903 used a chain and sprocket drive to connect a tractor to other devices, an early example of versatility in this area. In 1904 at Perth a demonstration was held of three practical farming tasks, with a Scott motor and an Ivel motor designed by Dan Albone. In 1905 the Scientific American Supplement carried an article "The Scott Gasoline-Motor-Propelled Agricultural Tractor". Photographs showed a rotary cultivator with a seed drill attached, and the "motor tractor and plowing engine". Power was provided by a 24 hp four-cylinder Aster engine.

Scott died in Hammersmith, in October 1909, aged 63.
