John Deere | Straw Chopper Knife – Smooth | Schumacher Radura PrimeLine | A05Y3
Genuine Schumacher A05Y3 | Smooth-edge tungsten carbide coated straw chopper knife designed for John Deere combine straw chopper systems using Schumacher Radura PrimeLine components. Commonly used in applications referencing OEM parts AI-KXE10256, KXE10152, and HXE15871.
Manufactured by Schumacher, the OEM supplier of Radura cutting systems used in many John Deere combines, this smooth straw chopper knife delivers controlled, uniform cutting performance while maintaining excellent durability in high-hour harvesting environments.
The cutting edge features a laser-clad tungsten carbide coating with extremely hard, embedded carbide particles. This advanced wear technology provides exceptionally high wear resistance and a significantly longer service life than standard smooth chopper blades, even in abrasive straw and residue conditions.
As the knife wears, the carrier material wears faster than the carbide coating, creating a continuous self-sharpening effect. This ensures the smooth cutting edge remains effective and cutting performance stays consistent throughout the service life.
A sharp, stable cutting edge helps maintain consistent engine load and power demand, reducing unnecessary energy loss and minimizing fuel consumption while supporting efficient chopping performance.
Designed for clean, efficient straw shredding and uniform residue distribution, this knife supports improved residue management, faster straw breakdown, and better soil incorporation after harvest.
