Fendt vs John Deere

Leasing of expensive equipment is also an option but generally is less popular except with larger producers. In the developing countries, the trend towards adoption of the tractor as the fundamental unit of agricultural mechanization systems is sure to continue. However, for many small farmers in deprived regions the transition to tractor-based mechanization is not a realistic option due to the lack of finance and basic infrastructure. In this situation, a continued reliance on human energy and animal-powered equipment for tillage, planting and harvesting will prevail for the foreseeable future.

Sophisticated hydraulic systems are now available on all modern tractors capable of performing additional functions including the operation and control of a multiplicity of implements and machines mounted to the rear, front or side of the tractor including loaders, mowers, agrochemical applicators, harvesters and feeders. While many of these are mechanically driven through the power-take-off (PTO) shaft at the rear of the tractor, hydraulic-drive systems provide additional flexibility due to the flexible power hoses that interconnect the driving and driven units.

Though these methods are still important, other means are perhaps more typical today, particularly the use of herbicide (plant-killing) chemicals. Another technique is to introduce insects that attack only the unwanted plant and destroy it while leaving the crop plants unharmed.

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).
