Deep ripper ГРД-5 (3300)
The purpose of the subsoiler is to destroy the plow pan, preserve moisture, help regulate the air-water balance, and increase fertility.
The HRD subsoiler helps to:
- create conditions for the accumulation of moisture from the air and its even distribution;
- increase porosity and improve the capillary system of the soil;
- activate biological processes that promote active root system development of crops and increase yields by 12-18%;
- remove excess rain and meltwater;
- reduce soil resistance when tractors operate with other equipment. This occurs by decreasing soil density, leading to fuel savings, reduced consumption of lubricants, and lower service loads;
