The Tractor is a versatile machine that has evolved from the original steam powered machines, though the iron horse stage to a very powerful computerized workstation, for a vast range of applications. 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 (Lorry). The farm tractor defined in history is both a vehicle that can pull a plough deeply in to the soil and do EVERYTHING that the farmers of the world want when working in and on the soil and on the road with trailers,trailed & mounted implements. It was,but only until 1973 that the proper historical definition as " Do-It-All tractor" for working with ALL the farmers implements. Times change,however and W.S.H.Taylor, in UK noticed that most farmers on large acreages used a tractor for most of the work but also needed a LAND-ROVER [THAT NAME LAND-Rover & later LAND-Cruiser being stated because in-field and between-field work of a certain kind demands a much quicker vehicle than the slow, ploughing-focused conventional tractor] as well as "the do it all" What was designed in to the Land-Rover`s early years was the central-drive position,the 3-point linkage & PTO but rarely used!!.It was Taylor that studied what the farm tractor was good at and what it was very poor at. He found that transportation was a much bigger user of tractor-time than any other duty on many, many farms.He also discovered that taking the seeds to the soil and spreading the fertiliser & spraying the herbicide were done slowly by the conventional tractor when "technically" it is easily possible to produce a vehicle to do these kind of tasks more quickly should a Land-Rover, vehicle-like concept was to exist. Taylor designed and built a Land-Rover & tractor-combined and he called it a TRANsport tracTOR [TRANTOR] because it was a proper tractor and had ALL of the features of a tractor but conducted MOST of the work on MOST farms much more quickly. Whilst the acceptance of the TRANTOR concept of tractor was designed for transportation & low-draught work tasks of a mowing,baling,bale-wrapping,chain harrowing etc kind and conducted the work more efficiently, due to its SPEED ,it might have been thought ,by some, that this was not a proper tractor. That,of course was fine whilst ploughing was so much a favoured ,soil-engaging activity of tractors. The Zero-Tillage system of Conservation Agriculture,especially in N.& S.America [the no-till alliances] & EC [ECAF] where entering the soil to a shallow-depth of no more than 2.5 inches & with a Low-draught direct-drill has simply changed the way farmers must,in future define what they mean by a tractor. A low-draft,high-speed[80kph]transport tractor that can accomplish ALL C.Ag.tasks [Drilling,Spreading Spraying,Transporting of the new no-till farming system [recommended by FAO] is re-defining what it is that we mean by FARM TRACTOR. In future,there are two kinds of tractor ONLY........at least,so far. The historical definition is "ploughing tractor & do-it all tractor" and the other is the"transport & low-draught focused tractor for ALL no-till work ". N.B. both kinds of tractor have all the features of that which has been developed since the steam age but some additional technical features have been added to increase speeds in the field & out.[see ten years of using these tractors on a UK arable farm, a cost-benefit analysis in a water authority and the fuel-benefits estimated for the movement of 7000-million tonnes of world crops 2009].These are contained on the website and in the pdf-style explanatory brochures......over to you Bulldozer.
