Left Curved Rotary Tiller Blade for BCS 725 Arco - Part Number: 56952

The Left Curved Rotary Tiller Blade (part number 56952, flat steel section 40 × 6 mm, mounting holes Ø 10.5 mm with 27 mm center-to-center distance, working dimensions X = 56 mm, Y = 115 mm, Z = 15 mm, adaptable OEM reference 580 48426) is a drop-forged, heat-treated wear part engineered for rotary cultivation. Designed with an arched curved profile in a left-hand orientation to operate in full dynamic balance alongside its matching right-hand blade, it ensures smooth soil penetration, fine clod crumbling, and reliable rotor dynamics across BCS rotary tillers and two-wheel tractors (model 725 Arco).

Key Features & Benefits

• Heavy-Duty 40 × 6 mm Forged Steel: Hot-forged from boron spring alloy and through-hardened for superior core toughness and abrasion resistance, preventing bending deformation or edge chipping during rock impacts.
• Compact “Arco” Curved Profile (Z = 15 mm): The 115 mm vertical working reach and 15 mm lateral offset minimize powertrain drag and optimize fuel efficiency while providing clean clod breakdown and furrow turnover.
• Dual 10.5 mm Holes with 27 mm Spacing: Precision 10.5 mm holes for M10 hardware feature a narrow 27 mm center-to-center spacing, ensuring a rigid, slip-resistant hold on genuine BCS rotor flanges.
• Seedbed Finishing & Inter-Row Cultivation: Well-suited for fine horticultural seedbed preparation, mechanical weed control between crop rows, and thorough mixing of plant residues and organic matter.
