Left Curved Rotary Tiller Blade for BCS Two-Wheel Tractor - Part Number: 55526

The Left Curved Rotary Tiller Blade (part number 55526, heavy-duty flat section 40 × 6 mm, mounting holes Ø 10.5 mm with compact 27 mm center-to-center distance, working dimensions X = 56 mm, Y = 130 mm, adaptable OEM reference 580 43434) is a high-strength drop-forged tillage part engineered to withstand severe bending stresses and continuous abrasive soil wear. Designed with a left-hand curved profile to operate in complete dynamic symmetry with its opposite right-hand partner, it provides smooth ground penetration, clean root cutting, and exact fitment onto BCS two-wheel tractor tillers (model 735).

Key Features & Benefits

• Heavy-Duty 40 × 6 mm Forged Alloy Steel: Hot-forged from boron alloy steel and through-hardened for superior wear resistance and elastic toughness, preventing permanent bending or fatigue fractures in stony and compacted soils.
• Optimized Left-Hand Curved Geometry: Operating dimensions (reach X = 56 mm, height Y = 130 mm) promote rapid soil slicing and clean furrow inversion while minimizing powertrain strain and fuel consumption.
• Dual 10.5 mm Holes with 27 mm Spacing: Features a compact 27 mm center-to-center spacing engineered for M10 hardware, ensuring a rigid, slip-resistant hold on factory BCS rotor flanges.
• Efficient Tilth & Weed Cultivation: Ideal for horticultural seedbed preparation, inter-row mechanical weeding, secondary tillage, and thorough incorporation of crop residues and organic amendments.
