Strelovidny deep compactor GRS-5.0
The GRS-5.0 deep tiller is intended for soil loosening on fallow and no-till backgrounds with deepening of the arable horizon, no-till cultivation instead of spring and spring plowing, deep loosening on slopes and steam fields.(//tractor-service.com)
The device forsurface tillage is used in the period of pre-sowing soil tillage in the spring and for the main tillage under wintercereals crops in autumn, for grain stubble, as well as after harvesting other crops, including long-stemmed ones, after preliminary husking with disc tools. The device performs additional loosening of the upper soil layer, leveling of the field surface, and partial grinding of long-stemmed plant residues.
In the system of no-till soil cultivation, deep loosening (chiseling) is an important technological operation that loosens the treated layer and destroys the compacted lower horizons (plow sole), increases the thickness of the root layer, improves the air, water, and thermal regimes of the soil, activates biological processes, accumulates soil moisture, and prevents water and wind erosion.
The looseners are more productive and less energy-intensive, provide a reduction in labor costs and fuel consumption per hectare, and an increase in the yield of cultivated crops.
