    • Thickened base, medium to heavy load wear-resistant: 2.7 mm thick (exceeding the standard 2.0 mm), designed specifically for wide headers and high-speed harvesting, suitable for medium to coarse straw such as wheat, rice, soybeans, and rapeseed. Wear-resistant and impact-resistant, with a lifespan 30%–50% longer than standard teeth.
    • Upper serration design for smoother cutting: Serrations are only distributed on the upper side of the blade edge, with a smooth lower side, reducing friction with the fixed blade, resulting in lower cutting resistance, no straw clogging, and clean crop cuts, suitable for high-speed harvesting at 10–14 mph.
    • Original factory precision fit: Dual hole spacing 52.35 mm, hole diameter 5.6 mm, 100% compatible with CNH 72C/74C and 2010/2020 cutter beams, direct replacement, no modification required, secure installation, and low vibration.
    • High cost-performance ratio and stable supply. Domestic mass production is mature, the quality is comparable to OEM, the price is 30%-50% lower, it is compatible with CNH mainstream wide cutting tables, and it has a wide circulation in the aftermarket and sufficient stock.

    • Suitable Crops: Wheat, Rice, Soybean, Rapeseed, Sunflower, Corn (soft stalks)
    • Operating Environment: Moderate humidity, dry stalks, small areas of weeds; suitable for wide headers (≥20 ft) and high-speed harvesting (10–14 mph)
    • Equipment Components: Header moving blade bar (Sickle Bar), which works in conjunction with fixed blades for reciprocating cutting.
