This harvester knife blade is fully compatible with New Holland (72C Grain Header, 74C Flexible Header) and Case IH (2010 Grain Header, 2020 Flexible Header) cutter beams.
The blade features a dual hole spacing of 52.35 mm and a hole diameter of 5.6 mm, designed for a precise original factory fit with no modifications required.
The 2.7 mm thickened base is engineered to withstand medium to heavy loads during high-speed harvesting. It increases the blade's wear resistance and impact resistance, extending its lifespan by 30% to 50% compared to standard blades.
It is highly suitable for harvesting wheat, rice, soybeans, rapeseed, sunflowers, and soft-stalk corn under moderate humidity and dry stalk conditions.
The upper serration design places cutting teeth on the upper side only, leaving the bottom smooth. This reduces friction against the fixed blade, prevents crop clogging, and ensures clean cuts at operating speeds of 10 to 14 mph.
Our blades are manufactured to strict OEM quality standards but are priced 30% to 50% lower, providing a cost-effective, high-durability solution with a stable and consistent supply.
