When you’re prepping fields and your blades won’t cut through residue anymore, it’s time to get back to serious tillage. Worn disc blades just push crop stubble around instead of cutting clean, leaving you with uneven seedbeds and potential planter problems come spring. This 22-inch smooth disc blade from Osmundson gets your harrow cutting like it should again.
What You’re Getting
- 22-inch diameter for good penetration and residue mixing without being too aggressive
- Boron 15B26 steel construction that’s hard enough to hold an edge but won’t shatter on rocks
- 3/16-inch thickness strikes the right balance between durability and weight
- 2.50-inch standard concavity provides proper soil throw and mixing action
- Single punch hole design fits 1-1/8 inch square axles perfectly
Built for Real Farm Work
This blade is designed for standard disc harrows used in primary and secondary tillage operations. Whether you’re breaking up corn ground after harvest, working down wheat stubble, or preparing a clean seedbed for planting, this blade handles typical farm conditions. The smooth edge works great for general tillage where you need good soil mixing without the aggressive cutting action of notched blades.
Made to Last
Osmundson doesn’t mess around with blade materials – this Boron 15B26 steel maintains the perfect hardness range 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 3/16-inch thickness provides solid durability for years of field work while keeping weight reasonable for your tractor.
Good to Know
Installation is straightforward – just slide it onto your square axle with the proper spacers. When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. If you’re doing a partial replacement, measure your existing blades first to ensure they’re all close to the same diameter.
