Notched or Plain Disc Harrow Blade 660 mm Diameter 37 mm Hexagonal Hole Boron Steel

Professional heavy-duty harrow disc, 660 mm diameter with a 37 mm hexagonal center hole and 6 mm reinforced thickness. Manufactured from Boron Steel (30 MNB 5), this 15.5 kg component is engineered for maximum penetration and superior structural strength on heavy-duty harrows.

Product Description

The 660 mm harrow disc with a 37 mm hexagonal mount represents the top-of-the-line solution for large-scale primary tillage. Thanks to its 6 mm structural thickness and the use of premium BORO 30 MNB 5 Boron steel, the disc offers unmatched resilience to mechanical shocks and prolonged abrasion resistance, even on highly compacted or rocky soils. The hexagonal center hole profile ensures optimal mechanical drive, distributing torque loads evenly and preventing shaft slippage or premature seat wear. Featuring an 87 mm concavity, this model guarantees massive and effective soil turnover, ensuring deep burial of voluminous crop residues and proper soil aeration. Available in both notched configuration (for aggressive crushing) and smooth (for powerful and uniform leveling).
