Brush tooth harrow BSHN-21 Solomiya, Dnepropetrovsk region.

Brush tooth harrow BSHN-21 Straw HarrowBrush tooth harrow BSHN-21 Straw has colossal efficiency in terms of productivity and quality of work.
The working body of the trailing harrow is a knife-shaped tooth that is attached to the hinge frame and has a rhombic cross-section, which, in comparison with the square harrow teeth that have been used for more than 50 years, allows you to significantly reduce the traction resistance of the entire harrow. And this, in turn, makes it possible to increase the working width and the overall productivity of the unit, while simultaneously reducing fuel costs and specific costs for tractor maintenance per unit of sown area.
The frames on which the teeth are located have a hinged structure, so they easily copy the soil relief, and the significant load on each tooth forces it to perform its direct function - tilling the soil without digging.
In addition, the articulated design of the harrows allows you to handle any amount of plant residues well, even straw bales in which heavy disc harrows are clogged, even after one pass will be perfectly distributed over the surface of the field, because the total length of the trail of two harrows is 5 m.. Even distribution of residues is the key to better performance of the units that will work after harrows, cultivators and seeders, and here there is no need to convince anyone,work of planters future harvest directly depends.
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 is very helpful, especially in spring. You can go to 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, if you made a moisture barrier in time and plucked the crust, you will increase your future harvest even more.
Due to its maneuverability and good transportability, it is possible to quickly move from field to field, the tractor driver does not need additional assistance for folding and unfolding, and the time of transfer from transport to working position takes 3-5 minutes.
Some of our clients, thanks to such flexibility, managed to harvest 800 hectares with a harrow in one day. Of course, such indicators do not happen every day, but they show the potential that is inherent in the harrow.
