Notched or Plain Disc Harrow Blade 610 mm Diameter 33 mm Square Hole Boron Steel 6 mm Thickness

Ultra-high resistance professional harrow disc, 610 mm diameter with a 33 mm square hole and 6 mm reinforced thickness. Manufactured from Boron Steel (30 MNB 5), it is the ultimate solution for primary tillage on extreme terrains with Nardi machinery.

Product Description

The 610 mm harrow disc with 6 mm thickness represents the performance peak for heavy-duty agriculture. Specifically designed for Nardi equipment (Ref. 11134139), this component is forged from BORO 30 MNB 5 steel, ensuring superior structural resilience and surface hardness that minimizes wear even in extreme abrasion conditions. With a net weight of 12.7 kg, the disc offers exceptional inertial penetration, ideal for crushing large clods and deep incorporation of tough crop residues. The 73 mm concavity facilitates fluid and effective soil turnover, preventing clogging of the disc gang. Available in both notched and smooth versions, it ensures total operational stability on 33 mm square shafts, drastically reducing maintenance time and operating costs per hectare.
