Description

When your disc blades are more polished than sharp, it’s time to bring back that bite that cuts through crop residue and levels your fields. A worn blade just pushes dirt around instead of actually working it, leaving you with poor seedbed prep and frustrated looks from the cab. This 20-inch Osmundson disc blade brings back the cutting action your harrow was designed to deliver.

What You’re Getting

Premium Boron 15B26 steel construction that’s heat-treated to 46-52 Rockwell hardness for long-lasting edge retention
Standard 1.88-inch concavity that moves soil effectively while maintaining proper penetration
Single punch mounting hole design for secure, wobble-free operation on your axle
3/16-inch thickness strikes the right balance between durability and efficient soil flow

Built for Real Farm Work

This disc blade fits any standard disc harrow or tiller running 1-1/8 inch square axles. Whether you’re working corn ground in the spring or breaking up pasture for renovation, this blade handles everything from light tillage to breaking down heavy residue. The smooth edge gives you clean cutting action without being too aggressive for finish work.

Made to Last

Osmundson doesn’t mess around with blade materials – this Boron 15B26 steel maintains its hardness through acres of tough tillage work. The steel composition resists wear while staying tough enough to handle the inevitable rocks and debris you’ll encounter. No fancy coatings needed, just quality steel that works season after season.

Good to Know

When you’re swapping blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that’ll leave mohawk strips in your field. Check your spool spacing while the gang’s apart, and consider doing the whole set at once since shipping costs are usually the same. A quick tip: coat blade edges with used oil during storage to prevent rust pitting that ruins cutting ability.
