Description

When you’re trying to manage heavy crop residue and get proper soil mixing in one pass, regular flat disc blades just don’t cut it. This 26-inch deep cone blade from Osmundson brings the aggressive cutting and throwing action you need to slice through tough stalks and properly bury residue. That deep cone design with 4.95 inches of concavity moves serious soil while the notched edge attacks residue like a saw blade.

What You’re Getting

Notched edge creates scissor action that slices through tough stalks other blades just bend over
Deep 4.95-inch concavity throws soil aggressively for maximum residue burial and mixing
Quality Boron 15B26 steel at 46-52 Rockwell hardness holds an edge through acres of tough tillage while staying tough enough to handle field stones
Single punch mounting for 1-1/2 inch square axles – direct replacement installation

Built for Real Farm Work

This blade fits any disc harrow using 1-1/2 inch square axles with appropriate spacing. The cone design is especially useful on John Deere disc harrows where you need that extra soil movement to properly incorporate crop residue in corn and soybean fields. Whether you’re working fall corn stalks or spring residue management, this blade handles the heavy lifting.

Made to Last

No fancy coatings here – just quality steel that works. The 1/4-inch thickness provides the durability needed for long service life in tough field conditions. This Boron steel maintains the perfect balance – hard enough to hold a sharp edge through rocky ground and tough stalks, but tough enough to handle the shock when you hit that hidden field stone.

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. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches. The deep cone design can be more aggressive than standard blades, so consider your soil conditions and residue levels when setting up your harrow.
