Description
When you’re dealing with worn disc blades that push through crop residue instead of slicing through it clean, you’re burning fuel and doing half the job you could be. This 28-inch smooth disc blade from Osmundson cuts through the toughest conditions while giving you the consistent tillage performance your fields need for proper seedbed preparation.
What You’re Getting
- Smooth edge design that works great for general tillage and finishing operations
- Standard 4.25-inch concavity creates proper soil flow and mixing action
- Single punch mounting for reliable, wobble-free attachment to your harrow
- Quarter-inch thickness strikes the right balance between durability and soil penetration
Built for Real Farm Work
This blade fits disc harrows with 1-1/2 inch square axles – a common setup on mid-size to larger disc harrows used for primary and secondary tillage. Whether you’re breaking up corn ground in the fall or preparing seed beds in spring, smooth blades like this one excel at creating even tillage without the aggressive cutting action of notched designs.
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 material and heat treatment process used by Osmundson ensures consistent performance season after season.
Good to Know
Installation is straightforward with the single punch design – just slide it onto the square axle and secure with your existing hardware. Keep an eye on blade wear by measuring diameter periodically; most blades are ready for replacement when they’ve lost 3-4 inches from their original size. Consider ordering full gang sets when you need replacements since shipping costs are often the same.
