Description

When your disc blades start looking more like dull wheels than sharp cutting tools, you know it’s time for replacements that’ll actually slice through crop residue instead of just pushing it around. This 22-inch smooth disc blade from Osmundson brings that sharp cutting edge back to your tillage operations, turning matted stalks and tough residue into manageable pieces that break down properly for next season’s planting.

What You’re Getting

22-inch diameter provides excellent soil penetration and residue cutting
Quarter-inch Boron 15B26 steel thickness for long-lasting durability
Standard 2.5-inch concavity moves soil effectively while maintaining stability
Single punch mounting hole fits 1-1/8 inch square axles perfectly
46-52 Rockwell hardness rating maintains sharp edges through tough conditions

Built for Real Farm Work

This blade fits disc harrows with 1-1/8 inch square axles, commonly found on a wide range of tillage equipment. Whether you’re working corn ground after harvest, preparing soybean fields, or incorporating cover crops, this smooth blade provides consistent cutting action. Your disc harrow needs to do more than just roll over crop residue – it needs to cut, size, and mix that material into the soil profile.

Made to Last

This Boron 15B26 steel maintains the perfect hardness range – hard enough 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 1/4-inch thickness provides the beef needed for long service life, while the 2.50-inch concavity creates the aggressive soil-throwing action that buries residue and levels fields.

Installation Notes

This is a direct replacement blade that mounts with the single punch hole design. When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. The single punch mounting means checking for elongated holes from wear – loose blades wobble and wear prematurely. Check your gang spacing while you have things apart to ensure proper blade clearance.
