Technology ArticleFarm Tractors A tractor is a vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery used in agriculture or construction. Most commonly, the term is used to describe the distinctive farm vehicle: agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised. Another common use of the term is for the power unit of a semi-trailer truck. The word tractor was taken from Latin, being the agent noun of trahere "to pull". . The first recorded use of the word meaning "an engine or vehicle for pulling wagons or ploughs" occurred in 1901, from the earlier term traction engine (1859). The first tractors were steam-powered ploughing engines. They were used in pairs either side of a field to haul a plough back and forth between them using a wire cable. In Britain, Ireland, Australia, India, Spain, and Germany the word "tractor" usually means "farm tractor", and the use of the word "tractor" to mean other types of vehicles is familiar to the vehicle trade but unfamiliar to much of the general public. In Canada and the US the word is also used to refer to a road tractor. Wikipedia Disclaimer Above information is from wikipedia and is freely distributed under the GNU license Also See: All Articles |
