Description
When your disc blades start looking more like dull coins than cutting tools, you need replacements that’ll actually bite into the soil instead of just riding over the surface. This 20-inch smooth blade from Osmundson brings back that clean cutting action your harrow needs to properly break up ground and leave a seedbed that’s ready for planting. At 7 gauge thickness with that smooth edge, it’s built for finishing work and maintaining an even depth across your field.
What You’re Getting
- Quality Boron 15B26 steel with 46-52 Rockwell hardness that holds an edge through acres of tough tillage but won’t shatter when you hit that hidden rock
- 1-1/2 inch round axle mounting with single punch hole for secure fit without wobbling or premature wear
- 7 gauge (4.5mm) thickness provides the right balance of durability and cutting performance
- Standard concavity gives you the proper soil-throwing action for effective cultivation
- Direct replacement design that mounts right onto your existing gang setup
Built for Real Farm Work
This blade fits disc harrows and cultivators running 1-1/2 inch round axles – the workhorses you’ll find on mid-size operations working corn, soybeans, and small grains. Whether you’re doing primary tillage after harvest, working down crop residue in the spring, or preparing a final seedbed before planting, smooth blades like this one give you that clean finish without the aggressive action that can sometimes work against you in lighter soils.
Made to Last
Osmundson doesn’t mess around with blade materials – this Boron steel maintains the perfect hardness range to hold an edge through tough conditions while staying tough enough to handle the occasional rock or root. The 7 gauge thickness gives you solid service life without being so heavy it bogs down in softer ground.
Good to Know
Never mix worn and new blades on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips in your field. This is a direct replacement that threads right onto your existing axle. While you’ve got the gangs apart, check your bearing condition and spool spacing to make sure everything’s running true.
