Description

When you’re dealing with corn stubble that just won’t cut or bean residue that’s matting up your disc gangs, you need blades that’ll actually slice through the mess instead of just pushing it around. This 18-inch notched disc blade from Osmundson gives you the aggressive cutting action to handle tough residue conditions and get your field properly worked in one pass.

What You’re Getting

Each notch creates a scissor action that slices through tough stalks other blades just bend over
Made from Boron 15B26 steel with 46-52 Rockwell hardness for long-lasting edge retention
3/16-inch thickness provides the right balance of durability and soil penetration
Combo hole design fits 1 square by 1-1/8 square axles with proper spacing
1.63-inch concavity throws soil aggressively for good mixing and leveling

Built for Real Farm Work

Your disc harrow needs to cut, size, and mix crop residue into the soil profile, especially in high-residue conditions like continuous corn or after cover crops. This blade fits most standard disc harrows running that common 1 square by 1-1/8 square axle setup you’ll find on older offset discs and many tandem units used for secondary tillage work.

Made to Last

Osmundson’s Boron 15B26 steel maintains the perfect hardness range—hard enough to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. The 18-inch diameter gives you plenty of cutting life, and you’ll know it’s time for replacement when you’ve lost about 3 inches of diameter.

Installation Notes

This is a direct bolt-on replacement for worn blades on your existing gangs. When you’re replacing blades, never mix worn and new ones on the same gang—the diameter difference creates uneven cutting that leaves mohawk strips in your field. Consider ordering a full gang set since shipping costs are often the same whether you get one blade or eight.
