When your disc harrow starts leaving ridges instead of smooth seedbed preparation, it’s usually the blades telling you they’ve seen better days. This 22-inch smooth disc blade from Osmundson brings back that clean cutting action you need for proper tillage, whether you’re working down corn stubble or preparing ground for spring planting.
What You’re Getting
- 22-inch diameter with smooth edge for clean soil inversion and minimal residue disturbance
- Combo hole design fits both 1-1/8 square and 1-1/4 square axles for versatile mounting options
- Made from high-grade Boron 15B26 steel with 46-52 Rockwell hardness for long-lasting cutting performance
- Standard 2.50-inch concavity provides proper soil flow and penetration
- 1/4-inch thickness gives you the durability needed for serious field work
Built for Real Farm Work
This blade works great on disc harrows used for seedbed preparation, residue management, and general tillage operations. Many operators run smooth blades on rear gangs for finishing after notched blades do the initial cutting on front gangs. The smooth edge gives you that fine finish you want when preparing ground for small seeds or when you need to size residue without chopping it too aggressively.
Made to Last
This Boron 15B26 steel maintains the perfect hardness range – hard enough to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. The consistent metallurgy means even wear patterns and reliable performance season after season.
Good to Know
The combo hole design means you don’t have to worry about getting the exact axle measurement – it’ll fit either size. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches, so at 22 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.
