Clearly additional investment in research and development is required to render the autonomous power supply options as economic and user-friendly as possible. Also, it should be noted that the purchased electricity supply, although not autonomous, could still be (at least in part) generated from renewable power sources. From a national perspective, renewable alternatives to diesel fuel for mobile equipment (e.g. oilseed fuels) (see also, Energy Sources: Renewable and Non Renewable) may also be considered as autonomous power.

This is based on the clear evidence of a global shift towards engine and motor driven mechanization systems. The situation is outlined in detail in Farm Machinery, (EOLSS on-line, 2002). Apart from the tractor, the farm machine that has captured the public imagination is the massive combine harvester, a miracle of modern technology.

So... here we have the largest ever #John_Deere tractor #9620RX in a comparison with largest ever #Case tractor #620_Quadtrac... For now, they are the largest tractors of each company and largest tractors of their series... both #Titans in size they compete each other . . .

Such machinery has facilitated the full or partial replacement of human- and animal-powered equipment in developed countries and increasingly in developing countries as well. The net result has been higher productivity and the welcome elimination of much of the drudgery of manual farm labor. For example, one person involved in agricultural production can now provide enough food and fiber for 128 others whereas only a century ago one person could provide food and fiber for only eight others (see also, Technology and Power in Agriculture).

Even when oilseeds (esterified, partially refined or crude) are used as diesel fuel extenders, the economic difficulty still persists and will continue until such time as diesel oil supplies begin to dwindle or until a more appropriate substitute fuel (renewable or nonrenewable) should emerge. Should diesel fuel supplies run out and an appropriate substitute fuel fail to emerge, tractors and other engine-driven equipment could convert to spark-ignition engines. These are more versatile in terms of fuel use (e.g. renewable alcohol, as well as nonrenewable hydrocarbons) even if less suited to the heavy workloads in agriculture.
