In the modern agricultural landscape, the 18 Inch Disc Harrow Blade serves as a critical component for soil preparation and crop residue management. As global farming transitions toward high-efficiency, large-scale operations, the demand for durable, wear-resistant blades has skyrocketed. From the vast corn belts of the American Midwest to the expansive soybean plantations in Brazil, the 18-inch specification has become the industry standard for medium-to-heavy-duty soil cultivation.
Current industrial data suggests that the global agricultural machinery attachment market is experiencing a CAGR of over 5.2%, driven by the need for "Conservation Tillage" which requires blades capable of slicing through tough organic matter while maintaining edge integrity. SHEN GONG, with over two decades of metallurgical expertise, is at the forefront of this evolution, applying aerospace-grade tungsten carbide technology to agricultural tools.
"MAKE SHARP EDGE ALWAYS IN REACH"
Sichuan Shen Gong Carbide Knives Co., Ltd., established in 1998, is a national high-tech enterprise specializing in RTP powder making to finished high-precision products.
The industry is shifting from traditional high-carbon steel to Boron steel and Tungsten Carbide-reinforced edges. Our 18-inch blades leverage TiCN-based cermet technologies to extend tool life by up to 300% in abrasive soil conditions.
AI-driven CNC grinding and laser-cutting are now standard. Precision in the concavity and bevel angle of a disc harrow blade ensures uniform soil penetration and reduces tractor fuel consumption.
Modern blades are designed for "low-disturbance" farming, helping to maintain soil structure and moisture. SHEN GONG's recycling initiatives for used carbide components align with global green manufacturing trends.
In the United Kingdom and Europe, our blades are favored for their precision in intensive seedbed preparation where soil finish is paramount. Conversely, in South America, the focus is on "High-Toughness" to withstand hidden rocks and heavy debris during primary tillage.
Our 18-inch disc harrow blades are engineered to meet these diverse needs. By utilizing WC-based cemented carbide, we provide a blade that doesn't just cut—it pulverizes and incorporates residue effectively, ensuring a perfect environment for the next planting season.
