When your disc harrow isn’t cutting through residue like it used to, it’s time to get those gangs back to doing what they’re supposed to do—slice, size, and incorporate crop material properly. This 28-inch smooth disc blade brings back that sharp cutting edge you need for effective residue management and seedbed preparation. With its pilot hole design, it fits a wide range of disc harrows where you need to drill your own center hole to match your specific axle size.
What You’re Getting
- Heavy-duty 8mm (5/16 inch) thickness that holds its edge through tough conditions
- Standard 4.25-inch concavity provides proper soil flow and mixing action
- Smooth edge design gives you a clean cut and consistent finish
- Pilot hole lets you drill the exact center hole size you need for your harrow
- Quality Ingersoll construction built for long seasons of field work
Built for Real Farm Work
This 28-inch blade is sized for larger disc harrows used on bigger operations—the kind of machines that cover serious acreage in corn, soybean, and wheat ground. Whether you’re working down corn stalks in the fall or prepping ground for spring planting, these larger blades give you the cutting diameter and soil penetration needed to handle heavy residue loads across wide working widths.
Made to Last
At 8mm thick, this blade has the heft to maintain its cutting edge season after season. The quality steel construction handles the constant impact and abrasion of field work, while the pilot hole design means you can get the perfect fit for your specific harrow setup without worrying about manufacturer variations in hole sizes.
Good to Know
The pilot hole comes pre-punched but undersized—you’ll need to drill it out to match your harrow’s axle size. Check for elongated holes from wear on your existing blades, as loose blades wobble and wear prematurely. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches. Consider ordering full gang sets—shipping’s often the same, and you’ll need them eventually.
