When your disc harrow isn’t cutting and mixing residue like it used to, it’s usually the blades that need attention. A sharp, properly-shaped blade makes all the difference between a harrow that actually cuts stalks and one that just rolls over them. This 24-inch smooth blade gets your harrow back to doing what it’s supposed to do—slice through residue, mix it with soil, and leave a level seedbed ready for planting.
What You’re Getting
- Heavy-duty Boron 15B26 steel that holds an edge through tough tillage conditions
- Rockwell hardness of 46-52 for the right balance of cutting ability and durability
- Standard 2.80-inch concavity that moves soil effectively without overworking it
- Combo hole design fits both square and round axle configurations for versatility
- Quarter-inch thickness provides long-wearing service life
Built for Real Farm Work
This blade fits disc harrows using 1-1/2 inch square by 1-5/8 inch round combination axles. Whether you’re working corn ground after harvest, breaking up compacted soil, or preparing a smooth seedbed, this blade handles the job. Smooth-edge blades excel at finishing work and creating that final level surface your planter needs.
Made to Last
Osmundson doesn’t cut corners on blade steel. This Boron 15B26 construction maintains the perfect hardness range—tough enough to slice through buried stalks and roots, but not so brittle it’ll chip when you hit that inevitable field stone. The quarter-inch thickness gives you plenty of steel to work with as the blade wears down over the seasons.
Good to Know
The combo hole design means this blade works on harrows originally equipped with either square or round axles in this size range. When replacing blades, always do complete gangs—mixing worn and new blades creates uneven cutting and leaves strips. Check your axle spacing while you’ve got gangs apart; proper blade spacing is critical for even soil flow and wear patterns.
