The new design of tractors

In the beginning of 19b0 th years of the last century on tractors there were seats with pillows and similarity of cabins for creation of more comfortable working conditions of tractor operators. However, such cabs have been linked to another kind of inconveniences - noise. The covering from sheet metal like a sound pickup strengthened noise of the engine, transmission and hydraulic system to such an extent that it affected the health of the tractor operator.
Since then the cabin has changed significantly. New tractor cab protects the driver from weather, noise and overturning consequences. Almost all of them are Soundproofed, comfortable seats, heating and ventilation, windscreen wipers and a quick control.
The majority of tractors the engine and transmission form uniform rigid skeleton of all car and consequently there is no need for a separate frame. The engine power is from 15 to 190 kW and above, however, in tractors is approximately from 22 to 90 kW.
Usually on tractors the diesel set engines providing a drive on back or on all four wheels. In addition, engines rotate shaft of selection the capacities which are the reason for trailed implements or those that are mounted on the tractor, and also for the hydraulic systems that control these guns.
The basic agricultural tool, the plow. Its purpose is much like a shovel - flip to, to loosen and grind the top layer of soil, at the same time burying crop residues and weeds. In the modern mechanised agriculture a plough cling to a tractor though in many countries, as before, use a simple plough to which put horses or bulls.
Before to sow grain in the ploughed earth, you need to perform the final stage of the preparatory work. Just as the gardener uses the rake to prepare the ground for planting, the farmer uses a harrow for alignment of the ploughed earth and destruction of weeds.
One more kind of cars for preparation of soil and destruction of weeds - a cultivator supplied with steel teeths, or ploughshares for loosening the earth. The milling cultivator, whose tines or the blade are at the leading of the shaft, can be used for preparation of preliminary not ploughed soil.
Today many cultures sow by means of cars which loosen soil, put in it seeds on the set depth and through certain intervals and then covered it with soil. Such cars sow at once some numbers.
