    • Thickened, coarse teeth for heavy-duty cutting.
      3.0 mm thick teeth with deep roots, designed specifically for thick stalks, hard stubble, and high-moisture crops (corn, sorghum, sunflower, wheat). Cuts without pulling or clogging, maximizing efficiency.
    • Double-edged design for cost-effectiveness and durability. Cuts on both sides; simply flip after wear for immediate use. Single-tooth lifespan increased by 50%+, significantly reducing replacement frequency and costs.
    • Original factory precision fit. Square hole size and spacing 100% match CNH cutter beams. Direct replacement, no modification required. Secure installation with minimal vibration.
    • Wear-resistant and impact-resistant for stable lifespan. Hardened blade edge + thickened base for impact and wear resistance. Lifespan increased by 40%–60% compared to ordinary blades. Suitable for medium-to-high-speed harvesting at 8–12 mph.

    • Suitable Crops: Corn, wheat, rice, soybean, sorghum, sunflower, rapeseed
    • Operating Environment: Hard stubble, dry straw, abundant weeds, high humidity, and other high-intensity working conditions
    • Equipment Components: Sickle bar, which works in conjunction with fixed blades for reciprocating cutting.
