Precision grinding guarantees an excellent cutting edge and helps original knives stay within the extremely narrow band of optimum weight tolerances.
Original John Deere straw chopper knives are zone hardened, allowing them to withstand higher stress levels.
To prevent cracks in the area of the pivot hole, John Deere knives are reamed after punching to ensure loads on the rotor are evenly spread.
