Description
When you need the aggressive cutting power of notched blades but have a custom axle configuration or need specific gang spacing, this 28-inch blade with pilot hole mounting gives you that flexibility. The pilot hole lets you drill the exact center hole size for your setup, whether you’re rebuilding an older harrow or building a custom tillage tool that needs to handle serious residue.
What You’re Getting
- Aggressive notched edge creates scissor action that slices through tough corn stalks and matted residue
- Pilot hole mounting lets you drill for your specific axle size and spacing requirements
- Premium Boron 15B26 steel at 46-52 Rockwell hardness holds an edge through acres of tough tillage
- Standard 4.25-inch concavity throws soil aggressively to bury residue and level fields
- Quarter-inch thickness provides the durability needed for long service life
Built for Heavy Residue Work
This 28-inch blade excels in high-residue conditions like continuous corn, after cover crops, or in no-till situations where you need aggressive cutting action. The notched design attacks stubborn crop residue that smooth blades just push around, turning it into properly sized pieces that’ll break down instead of wrapping around your planter next spring.
Made to Last
Osmundson doesn’t mess around with blade materials – this Boron 15B26 steel maintains the perfect hardness balance. Hard enough to hold an edge through tough conditions, but not so brittle it shatters when you clip that hidden field stone. No fancy coatings, just quality steel that works.
Installation Notes
The pilot hole mounting means you’ll need to drill the center hole to match your specific axle size – measure twice, drill once. Never mix worn and new blades on the same gang – the diameter difference creates uneven cutting that leaves strips in your field. Consider ordering full gang sets – shipping’s often the same, and you’ll need them eventually.
