1BZ Series Hydraulic Offset Heavy-Duty Disc Harrow – Full Product Description
The 1BZ Series Hydraulic Offset Heavy-Duty Disc Harrow is a trailed heavy tillage equipment purpose-built for medium and small horsepower tractors. It offers 9 standard working width options from 1.6m to 4.4m, perfectly compatible with mainstream tractors in the 65-160HP power range, and serves as a highly cost-effective high-efficiency tillage solution for small family farms and agricultural cooperatives.
Key Product Advantages
- Reliable & Outstanding Operation Performance
It delivers a maximum working depth of 200mm, equipped with high-strength wear-resistant discs for exceptional soil penetration. It can complete stubble breaking and soil crushing in one pass even on compacted dry farmland and high-residue fields, leaving a perfectly level seedbed with fine soil particles that is ready for sowing without secondary finishing. - Lightweight Yet Heavy-Duty Durable Design
Compared with extra-large heavy-duty models, this series optimizes the overall weight while retaining full structural strength. The lightest unit weighs only 1000kg, and the maximum gross weight is controlled at 2300kg, which will not place extra traction burden on medium and small horsepower tractors. The thickened square steel frame and reinforced disc axle resist deformation under daily operation, delivering extremely low long-term failure rate. - Hydraulic Control for Effortless Operation
The hydraulic system directly adjusts the working depth, operators can fine-tune tillage depth directly inside the tractor cabin, no manual on-site adjustment is required. It drastically cuts down the labor intensity for single-person operation, even new operators can master the full workflow quickly. - Excellent Trafficability for Easy Transfer
Equipped with standard agricultural walking tires, the trailed structure requires no extra complicated hooking and debugging. It moves flexibly between fields and on public roads, avoiding the road scraping issue common to traditional 3-point mounted harrows, and greatly improves cross-site operation efficiency.
Typical Applications
It is widely used in pre-seedbed preparation for dry farmland, small wasteland reclamation, orchard inter-row tillage, and straw-soil mixing after straw returning. One single machine replaces multiple traditional manual tillage processes, and effectively cuts the overall tillage cost for small and medium farms.
