Description
When your disc blades start pushing residue around instead of cutting through it cleanly, it’s time for fresh steel that gets the job done right. This 22-inch smooth disc blade from Osmundson brings back the clean cutting action your harrow needs, whether you’re working spring seedbed prep or fall tillage operations.
What You’re Getting
- Smooth edge design that creates a clean finish for final tillage passes
- Premium Boron 15B26 steel maintains 46-52 Rockwell hardness – tough enough for acres of work but won’t shatter on rocks
- 2.50-inch concavity provides proper soil flow and throwing action
- Combo hole design fits both square and round axle configurations
- 3/16-inch thickness balances durability with proper soil penetration
Built for Real Farm Work
This blade fits disc harrows with 1-1/8 x 1-1/4 square axles, common on mid-size tillage equipment used for seedbed finishing, residue incorporation, and general field conditioning. Many operators run smooth blades on rear gangs for finishing after notched blades on front gangs handle the heavy cutting.
Made to Last
Osmundson doesn’t mess around with blade materials – no fancy coatings here, just quality steel that works. The Boron steel construction holds an edge through acres of tough tillage while resisting breakage when you hit that inevitable field stone.
Good to Know
Never mix worn and new blades on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. When storing your disc harrow, coat blade edges with used oil to prevent rust pitting, and track blade wear by measuring diameter annually.
