Right Curved Rotary Tiller Blade for BCS / Bertolini / Grillo - Part Number: 55008

The Right Curved Rotary Tiller Blade (part number 55008, flat steel section 30 × 6 mm, mounting holes Ø 10.5 mm with 66 mm center-to-center distance, working dimensions X = 72 mm, Y = 190 mm, Z = 20 mm, adaptable OEM reference 58042306) is a drop-forged, heat-treated wear part engineered for severe abrasive wear and impact durability. Featuring a right-hand helical curvature, it ensures smooth soil entry, efficient clod crumbling, and balanced rotor dynamics across rotary tillers and two-wheel tractors from BCS (models Rotary Tiller 705 Standard, Two-Wheel Tractor 705), Bertolini - Yabe (model Rotary Tiller S.305 HP 7.5 Helical Arc), and Grillo (model Rotary Tiller GN 10 Standard 131 Helical Arc).

Key Features & Benefits

• Forged & Through-Hardened Alloy Steel: Fabricated from 30×6 mm wear-resistant steel stock and quenched to maintain edge sharpness, resisting deformation and brittle fracture during rock strikes.
• Optimized Right Helical Arc (Z = 20 mm): The calibrated curvature (working reach X = 72 mm, height Y = 190 mm, lateral offset Z = 20 mm) promotes progressive soil slicing and clean soil inversion while reducing engine load and fuel consumption.
• Precision 10.5 mm Mounting Holes (66 mm Spacing): Dual 10.5 mm bolt holes suited for M10 hardware are accurately machined to match factory BCS, Bertolini, and Grillo rotor flanges, ensuring a rigid, play-free fit.
• Fine Seedbed Preparation: Ideal for secondary tillage, inter-row mechanical cultivation, seedbed finishing, and uniform incorporation of organic amendments and crop residues.
