SKU: SMA-114-221406N Notched Disc Blade for Standard Disc Harrows with 1-1/2 Inch Round Axle

When your disc blades start looking more like smooth wheels than cutting tools, it's time for replacements that'll actually slice through residue instead of just pushing it around. This 22-inch notched blade brings aggressive cutting action back to your harrow, turning tough corn stalks and matted residue into properly sized pieces that'll break down instead of hair-pinning around your planter next spring.

What You're Getting

• Aggressive notched edge that creates scissor action to slice through tough stalks other blades just bend over
• Heavy-duty 1/4-inch thickness provides the beef needed for long service life through acres of tough tillage
• Quality Boron 15B26 steel maintains 46-52 Rockwell hardness - hard enough to hold an edge but not so brittle it shatters when you clip a hidden field stone
• 2.50-inch concavity creates the soil-throwing action that buries residue and levels fields
• Single punch mounting hole for secure, wobble-free attachment to your harrow gangs

Built for Real Farm Work

This blade fits disc harrows using 1-1/2 inch round axles and handles everything from spring tillage to fall residue management. In high-residue conditions like continuous corn or after cover crops, that notched edge makes the difference between effective residue management and a plugged-up mess. Whether you're working through corn stalks, bean stubble, or cover crop residue, this blade cuts aggressively while maintaining smooth operation.

Made to Last

Osmundson doesn't mess around with blade materials - no fancy coatings here, just quality steel that works. The Boron steel construction handles the punishment of rocks, roots, and heavy residue while maintaining its cutting edge season after season. At 22 inches starting diameter, you've got plenty of service life ahead when maintained properly.

Installation Notes

This is a direct replacement that mounts with standard hardware. When replacing blades, never mix worn and new on the same gang - the diameter difference creates uneven cutting that leaves mohawk strips. Track your blade wear by measuring diameter annually; most blades are shot when they've lost 3-4 inches. Consider ordering full gang sets since shipping's often the same and you'll need them eventually.
