Left Curved Rotary Tiller Blade for BCS / Grillo / Lampacrescia / SEP - Part Number: 55523

The Left Curved Rotary Tiller Blade (part number 55523, flat steel section 25 × 6 mm, mounting holes Ø 8.5 mm with 55 mm center-to-center distance, working dimensions X = 55 mm, Y = 165 mm, Z = 20 mm, adaptable OEM reference 582 43431) is a drop-forged, heat-treated wear part engineered for abrasion resistance and impact toughness. Designed with a left-hand helical curvature to operate in complete dynamic synergy alongside its matching right-hand partner, it provides clean ground cutting, fine clod crumbling, and balanced rotor dynamics on walk-behind tillers and two-wheel tractors from BCS (model 715 Grillino B4), Grillo (model Grillino B4 Arco Elic.), Lampacrescia (model Kombi 2 Arco Elic.), and SEP (model 1000).

Key Features & Benefits

• Forged & Through-Hardened Spring Steel: Manufactured from 25×6 mm heavy-duty steel stock and heat-treated to preserve cutting edge sharpness, preventing plastic deformation or brittle fractures upon collision with stones.
• Optimized Left Helical Arc (Z = 20 mm): The calibrated geometry (working reach X = 55 mm, height Y = 165 mm, lateral offset Z = 20 mm) promotes gradual ground slicing and clean soil inversion while reducing engine load and fuel consumption.
• Precision 8.5 mm Mounting Holes (55 mm Spacing): Dual 8.5 mm bolt holes suited for M8 hardware are accurately machined to match factory BCS, Grillo, Lampacrescia, and SEP rotor hubs, ensuring a rigid, play-free seat.
• Fine Seedbed Preparation: Ideal for horticultural row crops, inter-row mechanical weeding, secondary tillage, and thorough incorporation of organic fertilizers and crop residues.
