Harry Ferguson, Irish engineer, invented the tractor (died 1960)

Henry George Ferguson was an Irish mechanic and inventor who is noted for his role in the development of the modern agricultural tractor and its three-point linkage system, for being the first person in Ireland to build and fly his own aeroplane, and for developing the first four-wheel drive Formula One car, the Ferguson P99.

A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, and now many more. 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.
