Hydraulically-Driven Tooth Harrow BZG-21 for Effective Soil Preparation

The tooth harrow (hydroficated) is designed to work on all soils with moisture content not exceeding 30%, field surface slope not exceeding 10%, soil hardness in the cultivated layer not exceeding 2.5 MPa, moisture closure, surface (up to 8 cm) cultivation of fallow fields; straw distribution and weed provocation. It is applied during the whole field season. Operations: straw destruction and distribution - the harrow works on the majority of plant residues; seed and fertiliser incorporation; pre-sowing provocation of growth and destruction of small weeds, moisture closing, weed provocation and loosening on fallow fields, distribution of plant residues, provocation of weeds and fallow after harvesting; rolling (packing) of the field - this task is easily solved by lowering the frame and setting the minimum angle of attack of the tines.
