The 1BZ series hydraulic offset heavy-duty disc harrow is a high-efficiency tractor-driven implement designed for superior soil penetration and post-plough soil loosening. It is highly adaptable to challenging conditions, including sticky heavy soil, uncultivated fields, and plots with dense weeds.
Constructed from welded square tubes, this harrow features a simple yet rigid structure ensuring durability. It is equipped with hydraulic lifting rubber wheels, which provide convenient transportation and a small turning radius. This advanced design dramatically improves both production efficiency and the operational lifetime of the harrow.
