GRC-3.0 Deep groover, Dnipropetrovsk region.

Strevoid deep groover ГРК-3.0 ГРК-3.0 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.
The device forsurface processing of soil is used during the period of pre-sowing soil processing in the spring and for the main processing under winter grain crops in the fall, 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.(//tractor-service.com)
In the no-till soil tillage system, 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 increase the yield of cultivated crops. The width of the grip is 3.0 m. Productivity in 1 hour of the main time - 2.7-3.5 ha/h. The working speed of movement is 8 km/h. Processing depth - up to 45 cm. Number of working bodies - 6 pcs. Depth of processing of the devicewith a roller 6-10 cm. Mass of the unit - 1725 kg Powertractor 280…320
