When your disc harrow starts leaving strips or pushing through residue instead of cutting it, worn blades are usually the culprit. This 26-inch smooth blade from Osmundson gets you back to doing clean, even work that properly sizes residue and leaves a finished seedbed ready for planting.
What You’re Getting
- Full 26-inch diameter gives you maximum working life before replacement
- Smooth edge provides clean cutting action and excellent finishing work
- Boron 15B26 steel construction with 46-52 Rockwell hardness for durability
- 4-inch concavity creates proper soil movement and residue mixing
- Single punch mounting hole fits standard 1-1/2 inch square axles
Built for Real Farm Work
This blade fits any disc harrow using 1-1/2 inch square axles with proper spacing. Whether you’re working corn ground, preparing soybean stubble, or finishing wheat fields, smooth blades like this one excel at creating that final finished surface. They work especially well on rear gangs where you want leveling and finishing rather than aggressive cutting.
Made to Last
This Boron 15B26 steel maintains the perfect hardness range – hard enough at 46-52 Rockwell to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. The quarter-inch thickness provides the strength needed for long service life without being unnecessarily heavy.
Good to Know
When replacing blades, don’t mix worn and new on the same gang—the diameter difference creates uneven cutting. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches. Consider ordering full gang sets since shipping costs are often the same and you’ll need them eventually.
