Spring-type deep harrow - designed for deep loosening of soil to a depth of 40-55 cm, destruction of plow sole without turnover of the layer and without damage to the stubble, deepening of the arable horizon. is used to improve the water-air environment of the root layer of the soil, which prevents the development of soil erosion and contributes to the accumulation of moisture and increase crop yields. In case of hitting hard and stony rocks independent tines of spring type perfectly bypasses the obstacle ensuring the safety of the machine, and the roller is designed for crushing and leveling the surface layer of soil and adjusting the depth of cultivation with the help of hydraulic depth control system.
