A tractor is an engineering vehicle specifically designed to deliver at a high tractive effort (or torque) 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 a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage, but nowadays a great variety of tasks. 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.
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 1896, from the earlier term "traction engine"
