Soil compaction and the hardening of the plow pan are major obstacles to increasing grain yields. Deep loosening—a core process in conservation tillage—breaks up the hard plow pan, improves soil aeration and moisture retention, and creates favorable conditions for crop root growth. As a critical component of deep-loosening machinery, the quality of the spring tines directly determines the effectiveness of the operation and the service life of the equipment. Recently, Jiangsu Fujie Knife Co., Ltd. has continuously optimized the manufacturing process for its deep-loosening spring tines; thanks to their superior performance, these products have gained widespread recognition in both domestic and international agricultural machinery markets.
The spring tine is the primary load-bearing component of deep-tillage equipment. During operation, it is subjected to continuous soil friction and impacts from stones; consequently, it requires both high flexural strength and excellent elastic deformation capabilities to absorb shocks. Conventional tines are prone to deformation, breakage, and rapid wear, which increase operating costs for farmers and hinder efficiency during critical farming periods. Drawing on years of experience in the R&D and manufacturing of agricultural machinery parts, Jiangsu Fujie Blade Industry has comprehensively upgraded and optimized the material selection, structural design, and heat treatment processes of its deep-tillage spring tines to ensure reliable performance across diverse and challenging field conditions.
This series of deep-tillage spring tines is manufactured from 60Si2Mn spring steel. Through precision forging and specialized heat treatment, the hardness is maintained within the HRC 42–48 range, striking an optimal balance between toughness and wear resistance. Their unique S-shaped curvature allows for elastic deflection when encountering obstacles such as stones or hard soil clods, effectively mitigating the risk of tine breakage or equipment damage and reducing downtime caused by mechanical failure. The tines feature an anti-corrosion coating for rust resistance and are suitable for diverse operating environments, including dryland, clay, and rocky or sandy soils. Compatible with a wide range of mainstream deep-tillage and combined tillage implements, they offer easy installation and high versatility, meeting the customization and integration needs of both large-scale domestic farms and overseas clients.
Step into the production workshop of Jiangsu Fujie Blade Industry, and you will see multiple automated production lines operating in an orderly fashion. Deep-tillage spring tines undergo a rigorous multi-step process—including blanking, hot forging, forming, quenching, powder coating, and inspection—with every batch subjected to sampling tests for mechanical properties to ensure strict quality control before shipment. As a high-tech enterprise with over two decades of experience in agricultural machinery parts, the company boasts a professional R&D team of engineers and champions the integration of industry, academia, and research; it offers customized solutions tailored to the soil conditions and farming practices of different regions. Its products are exported to more than fifty countries and regions worldwide, with agricultural components such as deep-tillage spring tines, rotary tiller blades, harrow discs, and plow points maintaining a stable market share in both domestic major grain-producing areas (such as Northeast and North China) and overseas markets.
As conservation tillage continues to advance, the market is demanding greater reliability for agricultural machinery wear parts. A representative from Jiangsu Fujie Blade Industry stated that the company will remain focused on the R&D of accessories for soil preparation machinery. By prioritizing technological breakthroughs—specifically enhancing wear resistance and service life while reducing costs and increasing efficiency—the company aims to empower modern agriculture, support stable grain production and increased yields, and help bring domestically produced agricultural machinery parts to the global market.
