Description

When your disc blades start looking more like smooth wheels than cutting tools, it’s time for replacements that’ll actually slice through residue instead of just pushing it around. This 24-inch notched disc blade from Osmundson brings aggressive cutting action back to your harrow, turning tough corn stalks and matted residue into properly sized pieces that’ll break down instead of hair-pinning around your planter next spring.

What You’re Getting

24-inch diameter with aggressive notched edge design that creates scissor action through tough stalks
Boron 15B26 steel with 46-52 Rockwell hardness – hard enough to hold an edge but tough enough to handle rocks
Quarter-inch thickness provides long service life while the 2.80-inch concavity delivers aggressive soil mixing
Single punch mounting hole fits 1-1/2 inch round axles – direct replacement for worn blades
No fancy coatings – just quality steel that works where it counts

Built for Real Farm Work

This blade fits disc harrows using 1-1/2 inch round axles and handles everything from spring tillage to fall residue management. Whether you’re working corn ground, bean stubble, or breaking up cover crops, the notched edge excels in high-residue conditions where smooth blades just can’t cut it.

Made to Last

Osmundson doesn’t mess around with blade materials – this Boron steel maintains the perfect hardness range to slice through acres of tough tillage without shattering when you clip that hidden field stone. The quarter-inch thickness gives you the beef needed for long service life in demanding conditions.

Good to Know

When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. Consider ordering full gang sets since shipping’s often the same, and you’ll need them eventually. Check for elongated mounting holes from wear, as loose blades wobble and wear prematurely.
