Disk machine UDA harrow-4.5-20

Units of the brandUDA are 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 located in the zone of sowing 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 simultaneously cut the lower layer of the soil layer, accordingly, the energy consumption of soil processing and the wear of the discs of these units is less than in known heavy disc harrows, which gives fuel economy.
