When you’re working tough ground with heavy residue, your disc harrow needs blades that can actually cut through the mess instead of just pushing it around. At 36 inches and a hefty 1/2-inch thick, this Ingersoll notched disc blade means business—bringing the aggressive cutting power you need to slice through corn stalks, wheat stubble, and matted cover crop residue that would bog down lighter blades.
What You’re Getting
- 36-inch diameter provides maximum ground coverage and soil-throwing action
- Heavy-duty 1/2-inch thickness and Boron 15B26 steel construction for long-lasting durability
- Notched edge design creates scissor action that slices tough stalks instead of bending them over
- 5-inch standard concavity moves serious soil and buries residue effectively
- Single punch mounting hole fits 2-1/4 inch square axles on heavy-duty harrows
Built for Real Farm Work
This blade is designed for the big disc harrows used on larger farming operations, where covering ground efficiently matters as much as doing the job right. The 2-1/4 inch square axle size tells you this isn’t for lightweight equipment—it’s built for the heavy-duty harrows that tackle the toughest tillage conditions, from breaking up compacted ground to managing heavy crop residue in no-till and minimum-till systems.
Made to Last
The Boron 15B26 steel holds its hardness at 46-52 Rockwell Scale, giving you the perfect balance between edge retention and impact resistance. This isn’t cheap steel that chips on the first rock—it’s engineered to maintain cutting ability through thousands of acres while standing up to the abuse of stones, roots, and hard ground that would destroy lesser blades.
Installation Notes
Never mix worn and new blades on the same gang—the diameter difference creates uneven cutting that leaves mohawk strips. Check for elongated mounting holes from wear, as loose blades wobble and wear prematurely. When you’re dealing with blades this size, having a helper makes installation much easier and safer.
