Zubova trail harrow wide-grip BSHN-21 Solomiya is designed for soil cultivation, which has tremendous efficiency in terms of productivity and quality of work.
The working body of the BSHN-21 trailing harrow is a knife-shaped tooth, which is fixed on a hinged frame and has a rhombic cross-section, which, in comparison with the square teeth of harrows, which have been used for more than 50 years, allows to significantly reduce the traction resistance of the entire harrow. And this, in turn, allows you to increase the width of capture and the overall productivity of the unit while simultaneously reducing the costs of PMM and the specific costs of maintaining the tractor per unit of cultivated area. The frames on which the teeth are located have a hinged structure, so they easily copy the topography of the soil, and the significant load on each tooth forces it to perform its direct function - tillage without digging. In addition, the hinged design of the harrows allows you to cope well with any amount of plant residues, even straw bales, in which heavy disk harrows are jammed, even after one pass will be perfectly distributed over the field surface, because the total length of the train from two harrows is 5 m. Even distribution of residues is a guarantee of better work of units that will work after the harrow - cultivators and
planter, and here you don't need to convince anyone that the future harvest directly depends on the work of
planter.
To adjust the degree of impact on the soil and plant residues, it is possible to set two positions of the tooth - in active and passive mode. The working depth of tillage is 3-6 cm, which helps a lot, especially in spring. You can leave the field much earlier, because unlike the pre-sowing cultivator, the trail harrow is not so sensitive to soil moisture, there is simply nothing to stick and clog. Therefore, by timely closing the moisture and tearing off the crust, you will increase your future harvest even more.
Due to the maneuverability and good transportability of the BSHN-21 trailing harrow, you can quickly move from field to field. To assemble and disassemble the harrow, the tractor driver does not need additional help, and the time of transfer from the transport position to the working position takes 3-5 waves • Unit type Semi-trailer
