With the acceleration of agricultural modernization, the performance details of agricultural machinery are increasingly becoming key to improving farming efficiency. Jiangsu Fujie Knife Industry Co., Ltd., a leading domestic supplier of agricultural machinery tools and accessories, recently upgraded its core product—the agricultural machinery-specific four-leaf spring. Thanks to its excellent mechanical properties and ultra-long service life, this product has quickly become the "golden partner" for rotary tillers, harrows, and other complete sets of equipment both domestically and internationally.
The newly launched four-leaf spring assembly uses high-quality 65Mn spring steel as its base material. In terms of manufacturing processes, Fujie Knives has abandoned traditional, simplified processing procedures and introduced intelligent heat treatment equipment for secondary strengthening of the spring leaves. By precisely controlling the quenching and tempering temperatures, the stress distribution within the product is more uniform, thereby significantly improving the elastic limit and fatigue strength.
In terms of structural design, this four-leaf spring adopts a multi-layer leaf spring stacked structure, which can effectively buffer the instantaneous impact force generated during agricultural machinery operation in complex soil environments, protecting the cutter shaft and transmission system from damage by hard objects. At the same time, the optimized arc surface design ensures that each spring fits more tightly when deformed under force, reducing the risk of breakage caused by excessive gaps. Its wear resistance and toughness are at the leading level in the industry.
As a national high-tech enterprise with over 20 years of experience in the industry, Fujie Knives not only holds the title of "Specialized, Refined, and Innovative Little Giant," but has also established a comprehensive quality control system covering the entire process from raw material analysis to finished product testing. The company's representative stated, "We not only sell accessories, but also provide a guarantee that the main unit won't be damaged. Although the four-leaf spring is small, it directly affects the flatness of the work area."
Currently, this series of four-leaf springs is compatible with most mainstream agricultural machinery brands on the market, and through Fujie Knives' global sales network, it is exported to Europe, America, and countries along the Belt and Road Initiative.
Founded in 1999 and headquartered in Yancheng, Jiangsu Province, Jiangsu Fujie Knife Industry Co., Ltd. is a leading enterprise integrating R&D, production, and sales of agricultural machinery parts. The company mainly produces over 5,000 products, including rotary tillers, springs, and plowshares, with exports accounting for over 80% of its products. It is committed to providing long-life cutting tools and accessory solutions for global agriculture.
