5(Compound conservative tiller (equipped with springs and rollers

As this machine makes it possible to prepare the soil without reversing it, it can be used to manage the residue and consequently to prevent the soil erosion and its moisture evaporation. An adequate overlap between the blades makes it possible to create an adaptable soil mesh and extirpate the weeds` roots. The notched convex discs break down the clods and mix the soil and the residue. Then the roller will level and fix the soil. By using this machine the farm traffic will be cut down and therefore the formation of hard pan and the plow pan will be postponed. Its safety system is composed of a spring that releases the stand whenever it hits an obstacle; besides it causes the blades vibrations and consequently the layers` failure and ventilation. And sure the tillage depth can be controlled.
