Agricultural machinery parts: Disc harrow blades, 20/22/24 inch, hardened and wear-resistant, notched/full-blade disc harrow blades.

Short Description:

The agricultural machinery harrow blades are forged from high-quality boron steel or 65Mn manganese steel, and undergo high-temperature heat treatment and oil quenching processes, resulting in extremely high hardness and wear resistance. The wavy/notched disc design provides strong soil penetration, easily chopping straw and cutting grass roots. Suitable for various disc harrows and combined tillage machines, it is widely used in farm straw return and land leveling operations, significantly improving soil breaking rate and operational efficiency.

This product is a disc harrow blade used in conjunction with agricultural machinery. It is a core, easily damaged component in land preparation operations and is suitable for stubble removal, cutting, breaking up, and mixing of crop residues under various soil conditions. The product is precision-manufactured from high-strength alloy steel and undergoes an overall heat treatment process, giving it both excellent hardness and toughness, effectively withstanding impacts from hard objects such as stones and tree roots.

Long wear resistance and lifespan: The cutting edge hardness reaches HRC 38-45, while the core maintains HRC 32-38 toughness, increasing the service life by more than 30% compared to ordinary harrow blades, reducing the frequency of replacement in the field.

Good soil penetration performance: Utilizing an optimized spherical curvature design, it features low cutting resistance and maintains a stable cutting depth even in compacted soil or dry conditions, improving operational efficiency.

Self-sharpening design: The cutting edge remains sharp throughout operation, preventing slippage and power loss due to dulling, and reducing tractor fuel consumption.

Standardized production: Certified by ISO 9001 quality management system, with precise mounting hole dimensions for quick matching with various brands of disc rake frames, requiring no secondary processing.

Applicable scenarios: stubble removal after harvesting crops such as corn, wheat, and soybeans; loosening soil in wasteland reclamation and fallow land; mixing organic materials such as straw and green manure in the soil.
