Rotary Tiller Blade is the core cutting and tilling components of a rotary tiller. They are typically fixed at even intervals on a rotating cutter shaft and are mostly made of 65Mn spring steel, 45# tempered steel, or wear-resistant alloy composite steel, possessing core characteristics of high-strength cutting, bending resistance, and soil abrasion resistance. Their working principle involves the tractor's power take-off shaft driving the cutter shaft to rotate at high speed (typically 200-300 r/min). After the blades enter the soil, they work through a triple action of "cutting - turning - crushing" to refine and loosen clumps of soil, while simultaneously mixing fertilizer, straw, and other materials. This makes them a key component for achieving "precision tillage."
