When your disc blades start looking more like smooth wheels than cutting tools, it’s time for replacements that’ll actually slice through soil and residue instead of just pushing it around. This 22-inch smooth disc blade from Osmundson brings reliable tillage performance back to your harrow, creating that perfect seedbed preparation you’re looking for without the aggressive cutting action of notched blades.
What You’re Getting
- 22-inch diameter provides excellent soil penetration and mixing action
- 1/4-inch thickness delivers the strength needed for years of field work
- 2.5-inch concavity creates proper soil throw and residue burial
- Single punch mounting hole fits standard 2-inch round axles perfectly
- Boron 15B26 steel construction maintains 46-52 Rockwell hardness for long edge life
Built for Real Farm Work
This blade fits disc harrows with 2-inch round axles and works great for general tillage, seedbed preparation, and residue incorporation. Smooth blades like this one excel in situations where you need good soil mixing without the aggressive cutting that can be too much in lighter soils or when working minimal residue conditions.
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 1/4-inch thickness provides the beef needed for long service life, while the quality steel construction means no fancy coatings are needed.
Installation Notes
When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches. Consider ordering full gang sets – shipping’s often the same, and you’ll need them eventually.
