The size and number of tractors is dictated by the size, nature and profitability of the farming enterprise as well as by how many (if any) operations (e.g. plowing, planting, spraying, harvesting) will be serviced by local contractors. For example, the capital cost of purchasing a harvester to harvest a small area of a moderate value crop is often prohibitive.The emphasis on shifts in power sources, especially the shift to tractors, can cause misunderstandings about which operations are the most likely candidates for mechanization in developing countries. This section therefore discusses mechanization in terms of operations and pays only occasional attention to power sources.
