Description
When your disc blades start looking more like smooth wheels than cutting tools, it’s time for replacements that’ll actually slice through soil instead of just pushing it around. This 20-inch smooth disc blade brings the finishing touch back to your disc harrow, creating that perfect seedbed preparation you need for uniform planting and emergence.
What You’re Getting
- Osmundson Boron 15B26 steel construction 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 a hidden field stone
- Quarter-inch thickness provides the beef needed for long service life while the smooth edge delivers clean soil finishing
- 2.00-inch concavity creates proper soil flow and mixing action without being overly aggressive
- Single punch mounting hole fits standard 1-1/2 inch square axle configurations
- Direct replacement – no modifications or adapters needed
Built for Real Farm Work
This blade fits any disc harrow using 1-1/2 inch square axles with appropriate spacing. Smooth blades excel as finishing blades on rear gangs, providing the clean soil preparation needed for optimal planting conditions. Whether you’re working corn ground, preparing soybean fields, or smoothing summer fallow, this blade delivers consistent performance across different soil types and conditions.
Made to Last
Osmundson doesn’t mess around with blade materials – no fancy coatings here, just quality steel that works. The Boron steel construction handles temperature swings, rocks, and the constant stress of field work while maintaining its cutting edge season after season.
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. The single punch mounting means checking for elongated holes from wear – loose blades wobble and wear prematurely. Consider ordering full gang sets since shipping’s often the same, and you’ll need them eventually.
