Description
When you’re looking at disc blades that are more worn than useful, it’s time for replacements that’ll actually cut through residue instead of just rolling over it. This 26-inch smooth disc blade brings back the aggressive cutting action your harrow needs to properly size crop residue and prepare a smooth, even seedbed for next season’s planting.
What You’re Getting
- Heavy-duty 1/4-inch thickness with 4.00-inch concavity for aggressive soil mixing
- Osmundson quality construction using Boron 15B26 steel
- 46-52 Rockwell hardness range for excellent edge retention
- Single punch hole design provides secure, wobble-free mounting
- Smooth edge delivers clean cutting action perfect for finishing work
Built for Real Farm Work
This blade fits disc harrows running 1-1/4 inch square axles, making it suitable for a wide range of medium to heavy-duty tillage equipment. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing, and this smooth blade excels at that finishing work—breaking down clods, leveling the field, and creating the fine tilth you need for good seed-to-soil contact.
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 durability needed for long service life while the smooth edge cuts cleanly without hair-pinning residue like worn blades do.
Installation Notes
Direct replacement installation—no modifications needed. The single punch mounting means checking for elongated holes from wear – loose blades wobble and wear prematurely. When replacing blades, it’s smart to measure your current ones first—most blades are shot when they’ve lost 3-4 inches. At 26 inches starting diameter, you’ve got good life ahead if maintained properly. Consider ordering full gang sets – shipping’s often the same, and you’ll need them eventually.
