When your disc blades look more like dull pizza cutters than sharp tillage tools, it’s time for replacements that’ll actually slice through crop residue instead of just rolling over it. This 22-inch notched disc blade brings that aggressive cutting action back to your harrow, with each notch creating a scissor action that slices through tough stalks that smooth blades just push around.
What You’re Getting
- Aggressive notched edge design that cuts through corn stalks and heavy residue without clogging
- Boron 15B26 steel construction hardened to 46-52 Rockwell for long-lasting sharpness
- 1/4-inch thickness provides the durability needed for season after season of tough tillage work
- Single punch hole fits your 1-3/4 inch round axle perfectly
- Standard 2.50-inch concavity creates the soil-throwing action you need for proper residue burial
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 attack residue aggressively, making them ideal for breaking down corn stalks, cover crops, and heavy wheat stubble before planting season.
Made to Last
This Boron 15B26 steel maintains the perfect hardness range – hard enough to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. The 1/4-inch thickness provides the beef needed for long service life in demanding field conditions.
Good to Know
When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. 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.
