Straw Chopper Blades & Knives for Combines and Residue Control

Effective residue management starts with sharp, balanced straw chopper blades. At Cutting Components, we offer a full range of high-quality straw chopper knives designed to deliver clean cuts, uniform distribution, and reliable performance during and after harvest. Whether you’re chopping straw on a small acreage or thousands of acres, sharp blades make a noticeable difference.

Our replacement blades are compatible with leading combine brands like John Deere, Case IH, New Holland, and more. Made from high-carbon or heat-treated steel, these knives resist dulling and fracturing—even in abrasive crop conditions. Proper residue breakdown improves soil health and tillage results, so keeping your chopper blades in good shape pays off long after the combine is back in the shed.

Farmers across North America choose Cutting Components for precision-fit chopper parts, fast shipping, and the field-proven reliability they need. Whether you’re replacing worn knives or doing a complete overhaul before next season, we’ve got the parts—and the know-how—to help you do it right.
