Description

When your disc blades start looking more like rolling wheels than cutting tools, it’s time for replacements that’ll actually slice through soil and residue instead of just pushing everything around. This 26-inch smooth disc blade from Osmundson brings back the precise cutting action your harrow needs, whether you’re working corn stubble, breaking up compacted soil, or preparing a clean seedbed for next season.

What You’re Getting

Heavy-duty 1/4-inch thickness handles tough field conditions and rocky soils without bending or chipping
Smooth edge design provides clean cutting and excellent soil mixing for finishing passes
Combo hole mounting fits both square and round axle systems with proper spacing options
Boron 15B26 steel construction with 46-52 Rockwell hardness for long-lasting edge retention
4.00-inch concavity creates proper soil throw and residue incorporation

Built for Real Farm Work

This blade fits medium to large frame disc harrows running 1-1/8 by 1-1/4 inch combination square axles. You’ll find these on everything from tandem disc harrows working corn ground to offset discs breaking up wheat stubble. The 26-inch diameter gives you the weight and cutting ability needed for deeper penetration in tough conditions while still maintaining good soil flow.

Made to Last

Osmundson doesn’t mess around with blade materials – this Boron steel maintains the perfect balance between edge retention and toughness. Hard enough to slice through acres of stubble and trash, but not so brittle it’ll shatter when you hit that inevitable field stone or root.

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 in your field. Check your spool spacing while you’ve got the gangs apart, and consider doing full sets since shipping costs are often the same whether you order one blade or twenty.
