Description

When your disc blades start looking more like dull wheels than cutting tools, it’s time for replacements that’ll actually slice through tough residue instead of just pushing it around. This 22-inch notched disc blade from Osmundson brings the aggressive cutting action back to your harrow, turning stubborn corn stalks and matted residue into properly sized pieces that’ll actually break down in the soil.

What You’re Getting

Each notch creates a scissor action that slices through tough stalks other blades just bend over
Boron 15B26 steel maintains perfect hardness at 46-52 Rockwell to hold an edge through acres of tough tillage, but won’t shatter when you clip a field stone
The 1/4-inch thickness provides the beef needed for long service life, while the 2.50-inch concavity creates soil-throwing action that buries residue
Direct replacement with single punch mounting – no modifications needed

Built for Real Farm Work

This blade fits disc harrows using 1-1/8 inch square axles and handles everything from breaking up sod to working down corn stalks. The 22-inch diameter gives you solid cutting performance whether you’re working pastures, preparing seed beds, or managing crop residue after harvest.

Made to Last

No fancy coatings here – just quality steel that works. The Boron steel construction handles the temperature swings, impacts, and constant abuse that come with field work, keeping its edge season after season while staying tough enough to survive the occasional rock or root.

Good to Know

Never mix worn and new blades on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. Check for elongated mounting holes from wear, as loose blades wobble and wear prematurely. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches from their starting diameter.
