When you need to break through heavy residue or work challenging soil conditions, having the right disc blade makes all the difference. This 28-inch smooth blade from Ingersoll is built to handle the tough work your harrow faces in the field, giving you clean cutting action without the aggressive tear-up that notched blades can create when conditions don’t call for it.
What You’re Getting
- 28-inch diameter provides excellent penetration and soil throw for thorough mixing
- 1/4-inch (6mm) thickness made from high-carbon boron steel for long-lasting sharpness
- Pilot hole design allows for custom mounting to fit various axle configurations
- Standard 4.25-inch concavity delivers proper soil flow and residue handling
- 46-52 Rockwell hardness rating means these blades hold their edge through rocky fields
Built for Real Farm Work
This disc blade shines in tillage operations where you need clean cutting without excessive soil disturbance. The 28-inch size gives you the weight and momentum to slice through corn stalks and soybean stubble while the smooth edge leaves a more refined finish than notched alternatives. Perfect for secondary tillage, seedbed preparation, and working fields with moderate residue loads.
Made to Last
Ingersoll uses boron steel construction that’s heat-treated to the sweet spot between toughness and edge retention. The single punch pilot hole design eliminates stress concentrations you’d get with multiple bolt holes, while the standard concavity keeps soil flowing properly to prevent plugging in sticky conditions.
Good to Know
The pilot hole requires custom drilling to match your specific axle size – most farm shops can handle this with a standard hole saw. When mounting, make sure you maintain proper blade spacing to avoid soil buildup between discs. A quick tip: check blade diameter annually with a tape measure; when you’ve lost 3-4 inches from wear, it’s time to start shopping for replacements.
