GROUP SCHUMACHER Straw Chopper Knives
Straw chopper knives are exposed to heavy wear at the blade edges, where Schumacher’s patented hard-cover design and special hardening process create a “beaver tooth” effect with one side harder than the other. As the softer material wears away, a sharp edge remains, ensuring consistent cutting performance and high-quality chopping results.

-Straight Design for All Chopper Types
PREMIUM straw chopper knives feature advanced hard cover technology for longer service life, reduced breakage risk, and a beaver tooth effect that maintains a sharp edge for consistent, high-quality chopping
