When you’re trying to manage heavy crop residue and get your seedbed ready for next season, standard disc blades just push stalks around instead of cutting through them. This 20-inch notched vertical till blade from Osmundson attacks that tough corn stubble and cover crop residue with aggressive cutting action. Each notch creates a scissor action that slices through tough stalks other blades just bend over.
What You’re Getting
- Double-punch 8-hole design that fits both John Deere/Norwood Kwik-Till and Degelman Pro-Till high-speed disc units
- Shallow concavity that’s perfect for vertical tillage – cuts residue without inverting soil layers
- Boron 15B26 steel that’s 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
- 1/4-inch thickness provides the durability you need for season after season of hard work
- 20-inch diameter gives you the right balance of cutting ability and reasonable replacement cost
Built for Real Farm Work
This blade is engineered for the unique demands of vertical tillage equipment where you need aggressive residue cutting without the deep soil mixing of conventional disc harrows. Whether you’re running a high-speed vertical till unit to size corn stalks or working through heavy cover crop residue before planting, this blade handles the job without plugging up your machine.
Made to Last
Osmundson doesn’t mess around with blade materials. The 1/4-inch thick Boron steel construction gives you the beef needed for long service life, while the precision-controlled hardness range ensures the blade stays sharp but won’t chip or crack when you hit rocks or roots.
Good to Know
The double-punch hole pattern means some holes won’t be used depending on your machine – that’s normal and won’t affect performance. If your old blades are worn down more than 2-3 inches from original diameter, replace the whole gang at once to maintain even cutting action across your tillage width.
