Notched or Plain Disc Harrow Blade 610 mm Diameter 37 mm Hexagonal Hole Boron Steel

High-performance professional harrow disc, 610 mm diameter with a 37 mm hexagonal center hole. Manufactured from 5 mm thick Boron Steel (30 MNB 5), it is engineered for deep penetration and superior structural resistance on heavy-duty harrows with hexagonal shafts.

Product Description

The 610 mm harrow disc with a 37 mm hexagonal mount represents the ideal solution for primary soil tillage and intensive crop residue management. With a 5 mm thickness and the use of premium BORO 30 MNB 5 steel, this 10.5 kg component offers exceptional impact resilience and surface hardness that drastically extends its service life, even in high abrasion conditions. The hexagonal center hole profile ensures optimal mechanical drive, distributing torque loads evenly and preventing slippage on the shaft. Featuring a pronounced 84 mm concavity, the disc ensures effective and wide soil turnover, promoting deep burial of organic matter and optimal soil aeration. Available in notched configuration (for aggressive cutting action) or smooth (for precision leveling).
