Description
When your disc blades are pushing residue around instead of cutting through it, it’s time for fresh steel that actually gets the job done. This 22-inch notched disc blade from Osmundson brings aggressive cutting action back to your harrow, turning tough corn stalks and matted residue into properly sized pieces that’ll break down instead of hair-pinning around your planter next spring.
What You’re Getting
- Notched edge design that creates a scissor cutting action through heavy crop residue
- Boron 15B26 steel construction with 46-52 Rockwell hardness for long-lasting durability
- 2.50 inch standard concavity that moves soil effectively while maintaining proper penetration
- Single punch mounting hole that fits 1-1/2 inch round axles found on many harrow gangs
- 3/16 inch thickness provides the right balance of strength and soil-cutting ability
Built for Real Farm Work
Your disc harrow needs to do more than just roll over crop residue – it needs to cut, size, and mix that material into the soil profile. These notched blades from Osmundson attack residue aggressively, with each notch creating a scissor action that slices through tough stalks other blades just bend over. This blade’s 22-inch diameter is commonly found on mid-sized harrows used for secondary tillage and residue management in corn and soybean ground.
Made to Last
The Boron 15B26 steel construction means this blade will hold its edge season after season, even in abrasive soils. The 46-52 Rockwell hardness gives you the perfect balance – hard enough to resist wear, but not so brittle it’ll chip when you hit a rock. This is the same quality steel that comes on original equipment from major harrow manufacturers.
Good to Know
Field-proven wisdom: Notched blades excel in heavy residue but can be too aggressive in light soils or minimal trash conditions. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing. The single punch mounting means checking for elongated holes from wear – loose blades wobble and wear prematurely. Consider ordering a full gang set since shipping costs are often the same whether you order one blade or eight.
