It mainly used for cleaning away stubble of plants before tillage, cutting straw onto the field, crushing clods after tillage, ground leveling and mulching in cropland. In dry cultivated field, this series may replace the plough to plough up and turn up the soil. Featured by high working efficiency, strong capability into the soil, and after-plough loose soil, this series can highly adapt to the sticky heavy field, uncultivated field and those plots of many weeds.The main integral harrow is made of square tubes welded together which ensures simple structure and good rigidity. The harrow is also equipped with hydraulic lifting rubber wheels for convenient transportation and small turning radius, thus the production efficiency and lifetime of the harrow is dramatically improved. The bearing for the harrow is made of taper bearing with sealing washer which is of strong rated load and low tractive resistance, thus guarantees the easy use and maintenance. All the above makes this series the more advanced cultivating agricultural tools in China.
