Tractor

A tractor is an engineering vehicle designed to deliver high tractive effort, meaning torque at slow speeds, so that it can haul a trailer or machinery. It is used in agriculture, mining and construction. In everyday use the word most often means the farm vehicle that supplies the power and traction to mechanize agricultural work, especially tillage, which was the original task, and many more jobs today. Farm implements may be towed behind the tractor or mounted on it, and where an implement is itself mechanised the tractor can also act as its source of power. The design emphasis on pulling force at low speed, rather than road speed, is what distinguishes the tractor from other powered vehicles.
