When you’re running a disc harrow that’s been around the farm for a while, finding the right blade that fits both the square and round axle configurations can be a real headache. This 24-inch smooth disc blade solves that problem with its combo hole design that works on harrows with either 1-1/2 inch square or 1-3/4 inch round axles. No more hunting for two different blade types or trying to make something work that doesn’t quite fit.
What You’re Getting
- Combo hole design fits both square and round axle configurations on the same blade
- Boron 15B26 steel maintains the perfect hardness range – hard enough at 46-52 Rockwell to hold an edge through acres of tough tillage
- Standard 2.80-inch concavity provides proper soil flow and residue mixing
- Smooth edge design gives you a clean finish for secondary tillage work
- Quarter-inch thickness delivers the strength needed for long service life
Built for Real Farm Work
This blade works great on disc harrows used for secondary tillage operations where you want a smooth finish rather than aggressive cutting action. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing, and this blade handles that finishing work perfectly. It’s ideal for working fields after primary tillage, preparing seedbeds, or working down crop residue that’s already been chopped.
Made to Last
Osmundson doesn’t mess around with blade materials. This Boron 15B26 steel maintains the perfect hardness range but not so brittle it shatters when you clip that hidden field stone. No fancy coatings here – just quality steel that works. The quarter-inch thickness gives you the beef needed to handle rocks and roots without bending or cracking.
Installation Notes
When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. The combo hole design means you’ll want to check your axle spacing to make sure the blade sits properly on whichever axle type you’re running. Consider ordering full gang sets – shipping’s often the same, and you’ll need them eventually.
