Product information
This series of 1BZ hydraulic trailed offset heavy-duty disc harrow is mainly applicable to clean the crop residue before tillage, break the hardened and impervious soil surface, crush and spread straw into the field, shatter soil after tillage, and level the land and preserve soil moisture. It can be used as tillage machine instead of plough on the cultivated land. With the efficient productivity,reasonable utilization of the power, great ability of cutting and shattering the soil ,the soil surface is smooth and loosening after harrowing, it is well suitable for heavy clay soil, waste land and weedy field as well. Having absorbed all advantages from such machines of foreigners and Chinese, it is designed according to the standard assembled structure, the main frame is welded with rectangular tubes, on which assembled with hydraulic lifting transportation wheels, adjustable spring device and special used bearing assemblies. Therefore this machine is strong and durable for operation and easy to be adjusted and maintained with the reasonable structure, small turning radius ,and is convenient for transportation,etc.
The disc spindle 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. The operations of shallow ploughing and stubble after crop harvest, soil moisture retention in early spring and crushed soil after ploughing are also aimed at the cover planting operation after sowing of the aircraft.
