1BZ series of hydraulic trailed off-set heavy-duty disc harrow
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.
