This chart shows Tractors Working by Country.
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 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 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.
Tractors can be generally classified by number of axles or wheels, with main categories of two-wheel tractors and four-wheel tractors ; more axles are possible but uncommon. Among four-wheel tractors , most are two-wheel drive ; but many are two-wheel drive with front wheel assist, four-wheel drive , or track tractors.
The predecessors of modern tractors, traction engines, used steam engines for power.
The classic farm tractor is a simple open vehicle, with two very large driving wheels on an axle below and slightly behind a single seat, and the engine in front of the driver, with two steerable wheels below the engine compartment. This basic design has remained unchanged for a number of years, but enclosed cabs are fitted on almost all modern models, for reasons of operator safety and comfort.
