ZBR spring, Poltava region.

Harrow with a spring tooth destroys weeds and prevents loss of moisture and nutrients necessary for crop growth. In addition, the harrow loosens the upper layer of the soil before and after sowing and breaks the rain crust.
The high quality of soil grinding is achieved thanks to the use of aharrow with a spring tooth. The variable angle of attack of the spring tooth regulates the depth oftillage, and the vibration of the teeth ensures the process of their self-cleaning from the earth and plant residues.
