Auto Reset Shank Parts For Cultivator

Precision-engineered for modern agricultural demands, these auto-reset shank parts are forged from high-grade 52CrMnMoV alloy steel using investment casting (±0.2mm tolerance) and 5-axis CNC machining (±0.05mm critical surface accuracy). The manufacturing process ensures optimal stress distribution across the shank’s curvature, capable of withstanding 8,000 lb impact loads during rock strikes. A complete thermal cycle—normalizing (900-920°C), annealing, oil quenching (850°C), and tempering (540-600°C)—achieves HRC 34-38 hardness for exceptional wear resistance in abrasive soils, while maintaining 12% elongation for controlled flex during auto-reset operation.

Available in original cast finish or protective black baking varnish, surface treatments include SAE J444 shot blasting for coating adhesion and optional Dacromet® coating (1,200+ hours salt spray resistance). IATF 16949-certified production includes 200% overload testing, magnetic particle inspection for micro-fractures, and CMM verification of pivot bore alignment (±0.1mm). The patented reset mechanism incorporates a 55° shear bolt design (Grade 8) and precision-ground wear plates (HRC 45+) for consistent tripping/recovery performance.
