This product is a high-performance replacement blade designed specifically for hand push lawn mowers, micro cultivators, and small agricultural machinery. The classic star shaped center hole design can perfectly mesh with the host drive shaft, ensuring efficient power transmission and effectively avoiding uneven cutting caused by slipping. The blade adopts an asymmetric structure, with the left blade providing strong cutting and the right blade having a specific curvature. When rotating, it generates upward airflow, throwing the trimmed grass debris into the grass collection bag or side outlet to improve the cleanliness of the lawn.

Precise transmission hole: Star shaped hole position (supporting polygonal star shape) is designed with precision, one-time molding, and extremely small tolerances to ensure smooth blade operation after installation and reduce host vibration.

Double edged efficient cutting: The blade is quenched or laser hardened at both ends, with sharp edges that can quickly cut various types of grass stems. Asymmetric design reduces repetitive pruning and improves work efficiency.

Ultra high durability: Made of high-strength steel, it can withstand the impact of foreign objects such as gravel and tree branches, and is not easy to crack or fracture. The black coating not only looks beautiful, but also provides excellent corrosion resistance.

Dynamic balance optimization: The product undergoes strict dynamic balance testing before leaving the factory, and has excellent stability during high-speed rotation, extending the engine shaft and service life.
