The disc unit with widths from 3,67m to 5,87m - is designed to handle all types of soil to a depth of 5 - 18 cm shuttle method, create an optimal natural structure of the soil for plant growth, and rolled down the topsoil for the conservation of soil moisture .These units combined the functions of a plow, plough-harrow, cultivators and disc harrow.
Mechanical restoration changes the ratio of solid, liquid, gaseous phases in the ground system and effect on the chemical, physico-chemical and biological processes, speeding up or slowing them down. However, over-cultivation of the soil can lead to the destruction of the structural units of the soil and reduction of fertility.
Disc units with cutouts ("Daisy"), which have a sharp edge around the perimeter, fine crushed stalks after reaping residues and weeds uniformly distribute them throughout the depth of the treated layer of soil, which leads to the decomposition of organic substances without mineralization and prevents oxidation of the soil. As a rotational axis arranged at an angle to the horizontal and wheels run on the clamp to the bar, they are cut at the same time the bottom layer of the soil formation, respectively tillage energy consumption and wear of the disc units is less severe than in prior disc harrow, which saves fuel.
