Notched or Plain Disc Harrow Blade 660 mm Diameter 42 mm Square Hole Boron Steel

Ultra-high resistance professional harrow disc, 660 mm diameter with a 42 mm square hole and 6 mm reinforced thickness. Manufactured from Boron Steel (30 MNB 5), it is the ultimate component for heavy-duty primary tillage on extreme terrains with Nardi machinery.

Product Description

The 660 mm harrow disc with a 42 mm square hole is the definitive solution for large-scale intensive agriculture. Specifically designed for Nardi heavy-duty equipment (Ref. 11134166), this component is forged from BORO 30 MNB 5 steel, ensuring unparalleled structural resilience and surface hardness that minimizes wear even in extreme abrasion conditions. With a net weight of 15.5 kg and a 6 mm thickness, the disc offers exceptional inertial penetration, essential for crushing large clods and deep incorporation of voluminous crop residues. The 87 mm concavity facilitates fluid and effective soil turnover, preventing clogging of the working organs. Available in both notched (for aggressive attack) and smooth (for powerful surface refinement) versions, it ensures total operational stability on large-section shafts.
