Notched or Plain Disc Harrow Blade 460 mm Diameter 37 mm Hexagonal Hole Boron Steel

Professional harrow disc, 460 mm diameter with a 37 mm hexagonal center hole. Manufactured from Boron Steel (30 MNB 5), this component offers exceptional wear resistance and optimal torque transfer, ideal for soil preparation with disc harrows equipped with hexagonal shafts.

Product Description

The 460 mm harrow disc with a 37 mm hexagonal mounting is a specialized technical component for soil cultivation and crop residue management. The use of BORO 30 MNB 5 steel, combined with advanced heat treatments, provides the disc with optimal hardness and superior resilience, allowing it to operate safely even in rocky or particularly challenging soils. The hexagonal profile of the center hole ensures uniform torque distribution along the shaft, preventing slippage and ensuring constant rotation. With a 74 mm concavity, the disc ensures excellent mixing of the surface layer, promoting aeration and the correct decomposition of organic matter. Available in both notched (for a more aggressive crushing action) and smooth (for uniform leveling) versions.
