Notched or Plain Disc Harrow Blade 510 mm Diameter 67 mm Hexagonal Hole Boron Steel

Professional harrow disc, 510 mm diameter with a 67 mm hexagonal center hole. Manufactured from Boron Steel (30 MNB 5), this component is designed to ensure torsional stability and ultra-high wear resistance on large-scale hexagonal shafts.

Product Description

The 510 mm harrow disc with a 67 mm hexagonal hole is a specialized technical solution for disc gangs requiring mounting on oversized section shafts. The use of BORO 30 MNB 5 steel, renowned for its exceptional mechanical properties following heat treatment, provides the disc with optimal hardness and resilience, capable of withstanding mechanical shocks without deformation. The specific geometry of the 67 mm hexagonal hole ensures perfect mechanical drive, distributing torque evenly along the shaft and eliminating risks of slippage or radial play. Featuring a 61 mm concavity, the disc promotes effective soil mixing and excellent incorporation of crop residues, improving soil structure. Available in both notched configuration (for a more aggressive attack) and smooth (for uniform leveling).
