Another breakthrough has been achieved in the field of agricultural machinery parts. The 3490467 special notched harrow blade, which is compatible with the Rubin series tillage machines, has completed its process design and large-scale mass production. With its wear resistance comparable to the original equipment manufacturer (OEM) and affordable price, it has quickly opened up the domestic and international agricultural machinery parts markets, effectively solving the industry pain points of expensive procurement and long replenishment cycles for parts of large imported tillage equipment.
The 3490467 is a core wear part originally supplied by the internationally renowned agricultural machinery brand, Recon. It has a diameter of 622mm, a thickness of 6mm, five 12.5mm square holes, and a serrated notch on the outer edge. It is primarily used for soil breaking, stubble removal, and deep tillage in farmland, and is suitable for complex farming environments such as black soil, sandy soil, and clay soil. Previously, this model of harrow blades relied heavily on imports from the original manufacturer, resulting in high unit procurement costs and overseas ordering cycles often lasting several months. Domestic large-scale farms and agricultural machinery repair shops frequently faced shortages of spare parts and idle machinery, becoming a bottleneck restricting the practical application of large imported agricultural machinery.
With the continuous advancement of high-standard farmland construction in China, the number of conservation tillage implements has been increasing year by year, creating a vast market space for the domestic substitution of high-end imported agricultural machinery parts. In recent years, many domestic specialized agricultural machinery parts manufacturers have focused on material improvement and heat treatment processes, conducting technical research on the 3490467 harrow blade. The product uses high-quality 65Mn spring steel raw materials, optimizes the entire process of stamping, high-temperature quenching, and tempering, and maintains a stable hardness of 38-45HRC for the finished product, balancing wear resistance and impact toughness. After on-site operation tests in farmland in multiple locations, the product's service life far exceeds that of ordinary domestic harrow blades, and its key parameters are highly consistent with original parts, allowing for non-destructive replacement of original parts.
In terms of production control, mass-production enterprises employ CNC blanking and fully automated spinning forming production lines. From raw material warehousing, precision machining, heat treatment to surface anti-corrosion spraying, multiple meticulous quality inspection processes are implemented to strictly control the dimensional errors of aperture, outer diameter, and curved surfaces, ensuring consistent quality across large batches of products. Currently, this type of harrow blade has been shipped in batches to large-scale planting areas in Northeast China, Xinjiang, and North China, and is also being exported in batches to Russia, Eastern Europe, and Western Europe. Orders from overseas agricultural machinery dealers continue to increase, and the product has gained recognition in both domestic and international markets due to its high cost-performance ratio.
Industry analysts indicate that the domestic mass production of the 3490467 harrow blade is a microcosm of my country's efforts to break the foreign monopoly in the niche market of agricultural machinery parts. Leveraging the advantages of Yancheng, Jiangsu's well-developed agricultural machinery parts industrial cluster, local manufacturers are continuously benchmarking against international first-tier agricultural machinery parts standards, constantly addressing shortcomings in high-end components, and accelerating the localization of imported agricultural machinery parts. In the future, with continuous technological upgrades, more imported machine-specific parts will be domestically produced, effectively reducing costs and increasing efficiency for planting entities nationwide.
Jiangsu Yancheng Fujie Knife Industry Co., Ltd. has been deeply involved in the research and development and production of disc rake blades and rotary tillage tools for more than 20 years. It is one of the core enterprises for the localization research and development and mass supply of the 3490467 model rake blade. Relying on its own mature production process and perfect export supply chain, it continues to provide standardized supporting products for customers at home and abroad.
