1BZ-2.2 20pcs Tractor Trailed hydraulic offset heavy duty disc harrow

Heavy type Wide Offset Disc Harrows are trailed type on two wheel. It can be easily transported to field.

Product Introduction:

        1BZ-2.2 20pcs hydraulic offset heavy duty disc harrow is based on the principle of traction farming. The set of concave discs is used as a working component. The insert blade edge plane is perpendicular to the ground and can be adjusted at an offset angle to the unit’s advancement direction. The insertion piece rolls forward, the cutting edge of the insertion piece cuts into the soil, cuts the grass roots and crop residues, and arranges the soil ridge to move along the concave surface of the insertion piece by a certain height and then shift. This disc harrow is worked as operations of shallow ploughing and stubble after crop harvest, soil moisture retention in early spring and crushed soil after cultivation.

This 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 .
