High Strength Manganese Steel Flail Knife, Universal Tractor Plow Blade Replacement, Wear-Resistant Swing Blade
This product is a wear-resistant rotary blade with a square hole groove, which is a core and easily damaged crushing accessory for straw returning machines, rotary tillers, and garden tillers. It is widely compatible with tractor-driven straw crushing and returning equipment for farmland, and is suitable for crushing and returning crop straw such as corn, wheat, and rice.
The product is made of high-strength, high-quality manganese steel through a single stamping and forging process. It undergoes professional high-temperature quenching and tempering heat treatment, resulting in high overall hardness and toughness, along with excellent wear resistance, impact resistance, and fracture resistance. During operation, it can withstand long-term friction and impact from sand, gravel, and straw in the field without easily chipping, deforming, or breaking. Its service life is far superior to that of ordinary cast iron or low-carbon steel blades, significantly reducing the frequency of replacement and maintenance and lowering operating costs for farmers.
The product adopts a double-fixing structure of top slot + central standard square hole. The slot is precisely positioned, and the square hole is neatly positioned. During installation, the buckle fits snugly against the shaft seat, and the bolts are tightened for a secure fixation. After installation, it is firmly in place without slipping, loosening, or falling off, ensuring strong operational stability. No secondary drilling or modification is required, and it can directly replace the blades of the same specification model, making disassembly and assembly convenient and efficient. The lower end of the blade body features an optimized arc-shaped wear-resistant cutting edge design, resulting in smooth and labor-saving pulverization with low tillage resistance. The straw is pulverized finely and evenly, effectively improving the efficiency of field return operations.
The surface is coated with a thickened blue high-pressure anti-corrosion paint, resulting in a dense and highly adhesive paint film. It offers excellent rust prevention, corrosion resistance, and resistance to moisture and soil erosion. Even under long-term operation in open fields, it is not prone to rusting or paint peeling, maintaining stable protective performance and appearance over the long term. The overall workmanship is meticulous, with smooth, burr-free edges, precise dimensional tolerances, and a high degree of fit on machines. It is a high-performance, cost-effective original replacement part for worn and aged blades used in agricultural straw crushing and rotary tillage operations.
