Double Slot Agricultural Rotary Tiller Blade, Heavy Duty Tractor Straw Crushing Replacement Part
This product is a double-fork slotted square hole type wear-resistant shredder for agricultural machinery. It is a core and easily damaged shredder part for straw returning machines, rotary tillers, and garden tillers. It is widely compatible with tractor-mounted equipment for crushing and returning crop straw to the field. It is suitable for crushing and returning crop straw such as corn, wheat, and rice to the field. It is a commonly used replacement part for farmers' field cultivation and land improvement.
This product is made from high-strength, high-quality manganese steel through a single forging process. It undergoes a professional high-temperature quenching and tempering heat treatment, resulting in high overall hardness and toughness, along with superior wear resistance and impact and fracture resistance. During operation, it can withstand long-term friction from hard objects like sand and gravel in the field, as well as high-speed rotating impacts, without easily chipping, deforming, or breaking. Its service life far exceeds that of ordinary low-carbon steel or cast iron blades, effectively reducing the frequency of parts replacement and significantly lowering the maintenance and operating costs for farmers.
The product adopts a double-fork opening slot at the top and a double-fixing structure with a standard square hole in the middle. The double fork slots precisely fit the equipment shaft seat, and the square hole bolt in the middle locks it in place. After installation, it is firmly secured without slipping, loosening, or falling off. It has strong stability during high-speed operation, and the dimensional tolerances are precise and uniform. No secondary drilling or modification is required, and it can directly replace the blades of the same specification model. Disassembly and assembly are convenient and efficient. The lower end of the blade body features a streamlined, wear-resistant cutting edge optimization design, making straw crushing smooth and labor-saving, with low tillage resistance and fine, uniform crushing, 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, ensuring a high degree of fit on the machine and good tillage stability. It is a high-performance, cost-effective original replacement for worn and aged blades used in agricultural straw crushing and rotary tillage operations.
