Thank you for supporting the creative commons movement !! A tractor is a chemi special propelled used for hauling or pushing trailers, implements or other machinery or heavy loads. There tractors for different tasks, such as agriculture, the construction, the earthwork or the maintenance of professional green spaces (compact tractors) or enjoyment of chemi. They are characterized mainly by their good adherence to the ground. A farm tractor is used to move agricultural trailers and agricultural work using tools. The tractor is also used in works of construction, usually with accessories such as blades or arms of backhoes. Today the agricultural world is ahead in the world of automotive electronics. Many tractors equipped for years a diagnostic system Can Bus, ie a system of two wires that run throughout the tractor (can hi and can low) providing information of all sensors, potentiometers, regulators... and are captured by drivers. A tractor can have the following drivers: engine, transmission, front suspension, cab suspension, cab driver, hydraulic controller, PTO, rear lift, air conditioner controller, driver armrest (60% of the tractor is operated from a console on the right armrest of the driver's seat). Therefore it is essential to proper maintenance of the tractor and ensure that you have protection structure and seat belt. In addition, the tractor must only be used by workers designated for this, which have undergone special training and have the game card. Meanwhile the tractor is obliged to make good use of the tractor according to the instructions and safety rules. The first tractors were steam tractors. They were used in pairs on either side of a field to plow, haul back and forth between them using a cable. Steam tractors were used successfully in the 1890s, and after 1900 tractors gasoline cheaper, began to replace horses plowing in the shot. The first units with internal combustion engine, ran on gasoline (petrol), then produced with cheaper fuel called oil. The first tractor diesel engine was produced by Benz-Sendling in 1922, in Germany. At present a mixture of oil is also used on compressed natural gas, making it even cheaper fuel for the engine and increase performance. These tractors are the way for future continue developing more advanced systems that enable progress in the agricultural field. A farm is an area of land, including various structures, devoted primarily to the production and management of food (production of vegetables, grains, or livestock ), fibers and, increasingly, fuel. It is based on food production. Farms may be owned and operated by a single individual, a family, community, corporation or a company. A farm can be one of any size from a fraction of a hectare to several thousand hectares. The commercial farms are intended for breeding cattle. The stables are used for operations primarily involved in the training of horses. A farm that is mainly used for the production of milk products and dairy is a dairy farm. There are also fish farms that raise fish in captivity as a food source. A farm school is a setting related to animal husbandry skills are taught. In the traditional sense of the farm consists of a cottage with several outbuildings, which depend on the forests, pastures and farmland property is called but in Catalonia and Valencia, farmhouse, also in Valencia and the Balearic Islands ; possession in Mallorca ; or place in Menorca. The development and independence of agriculture occurred in northern and southern China, in the Sahel of Africa, in New Guinea and in various regions of the Americas. The eight crops called founding fathers of Neolithic agriculture, were firstly the cereals : wheat " spelled "wheat" mop "after the barley ; the legumes : peas, lentils, bitter vetch, chickpeas ; and linen. Despite its advantages, according to some anthropologists, agriculture meant a reduction of variety in the diet, creating a change in the evolution of the human species to more vulnerable individuals and dependents of an enclave than their predecessors. The division of the world into developed and underdeveloped agriculture was one aspect: the first characterized by a specialized market and agriculture with high yields (even in so-called new countries where population pressure on the surface is less) ; while in the second there was a zoning between subsistence farming family farms with traditional technology and under pressure from population growth, agriculture and plantation monocultures for the international market, which also puts pressure on increasingly lower natural areas.
