Disk harrow UDA-3.1-20, Kharkiv region.

Disk machine UDA harrow-3.1-20 UDA brand unitsUDA intended for processing all types of soil to a depth of 4...18 cm for sowing cereal crops, annual and perennial grasses, sunflower, corn. Since the aggregates grind and mix the soil without overturning the layer, the upper nutrient layer of the soil, rich in microflora, is placed in the zone of seeding and development of the root system of plants, which increases the yield by 15-25%. The units are equipped with discs with cutouts that have a sharp edge around the entire perimeter, perfectly grind the stalks of post-harvest residues and weeds, evenly distribute them throughout the depth of the treated soil layer, which leads to the decomposition of organic substances without mineralization and prevents soil oxidation. Since the axes of rotation are placed at an angle to the horizontal and the discs cut the lower layer of the soil at the same time, the energy consumption of soil processing and the wear of the discs of these units are less than in known heavy disc harrows, which gives fuel economy.
