Description
When you’re dealing with tough crop residue and stubborn stalks that just won’t break down, you need disc blades that actually cut instead of just pushing material around. 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. Each notch creates a scissor action that slices through tough stalks other blades just bend over.
What You’re Getting
- Boron 15B26 steel construction that’s hard enough at 46-52 Rockwell to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone
- 3/16-inch thickness provides the right balance of durability and cutting performance for standard disc harrow work
- Notched edge design that attacks residue aggressively instead of just rolling over it
- 2.50-inch concavity creates proper soil throw and mixing action
- Single punch hole design fits standard 1-1/2 inch square axles with proper spacing
Built for Real Farm Work
This blade fits any disc harrow using 1-1/2 inch square axles, making it a versatile replacement for worn blades on a wide range of tillage equipment. Whether you’re working through corn stalks, soybean stubble, or cover crops, the notched design excels in high-residue conditions where smooth blades just can’t get the job done. In high-residue conditions like continuous corn or after cover crops, that notched edge makes the difference between effective residue management and a plugged-up mess that forces you to make extra passes.
Made to Last
Osmundson doesn’t cut corners on blade materials. No fancy coatings here – just quality steel that works. The Boron steel construction holds up to the punishment of rocky fields and abrasive soils while maintaining its cutting edge season after season. At 22 inches, you’ve got plenty of service life before the blade wears down to replacement size.
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. 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.
