Description
When your disc harrow starts rolling over crop residue instead of cutting through it, worn blades are usually the culprit. This 22-inch smooth disc blade from Osmundson brings back that clean cutting action you need for proper seedbed preparation, whether you’re working corn stubble or preparing ground for spring planting.
What You’re Getting
- Boron 15B26 steel with 46-52 Rockwell hardness that holds its edge through acres of tough tillage
- 3/16-inch thickness provides durability without being overly heavy on your disc gang
- 2.50-inch concavity gives you the right amount of soil throw for mixing and leveling
- Combo hole design fits both square and round axles for maximum versatility
- Smooth edge design excels at finishing work and creating uniform seedbeds
Built for Real Farm Work
Many operators run notched blades on front gangs for cutting, smooth on rear for finishing. This blade handles the finishing duties perfectly, creating that level, well-mixed seedbed your planter needs. It’s sized right for smaller to mid-size disc harrows working everything from minimum-till corn ground to full-width tillage operations.
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. No fancy coatings here – just quality steel that works.
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. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches. At 22 inches starting diameter, you’ve got plenty of service life ahead when maintained properly.
