Agricultural machinery parts: Disc harrow blades, 20/22/24 inch, notched harrow blades
In modern agricultural operations, the disc harrow blade is a core wear-prone component of tillage machinery, and its quality directly determines the soil breaking rate, operational efficiency, and equipment lifespan. This high-strength, wear-resistant disc harrow blade is specifically designed to handle complex and harsh soil environments. Whether it's hard, compacted soil, heavy clay soil, or barren land rich in gravel, it can achieve efficient soil cutting, breaking up, and leveling operations.
1、Premium Materials, Extra-Long Lifespan
This product uses 65Mn (65 Manganese Steel) and 30MnB (30 Manganese Boron) high-end alloy steel as its base material. Through high-temperature heat treatment and oil quenching, the rake blades possess both extremely high hardness and excellent toughness. The surface hardness of the cutting edge can reach 38-45 HRC, while the core maintains good plasticity, effectively solving the problems of traditional rake blades being prone to chipping, rolling, and breakage. Its service life is more than twice that of ordinary carbon steel rake blades.
2、Exquisite craftsmanship, precise operation. Each rake blade is formed in one piece by a 10,000-ton press, ensuring precise and consistent curvature and uniform thickness. The cutting edge undergoes secondary grinding, resulting in excellent sharpness and strong soil penetration. It can easily cut crop stalks, prevent tangling, and significantly reduce tractor traction resistance, thereby achieving fuel saving and efficiency improvement.
3、Diverse Sizes, Wide CompatibilityWe offer a full range of sizes from 18 inches to 32 inches in diameter, with various blade designs including notched, round, and serrated, to meet diverse agronomic needs.
Notched: Suitable for wasteland reclamation and heavy clay soils, with strong penetration and excellent chopping effect;
Round: Suitable for secondary land preparation and soil leveling, with fine soil fragmentation and good covering effect;
Serrated: Suitable for fields with straw return, with strong cutting ability for crop residues and prevents clogging.
This product is widely applicable to various stages of farm operations, including stubble removal, soil loosening, fertilizer mixing, land leveling, and weed control, in large farms, large-scale cooperatives, and individual contractors. It performs particularly well in spring planting preparations and straw return operations after the autumn harvest.
