Description

When your disc harrow blades start looking worn down and aren’t cutting like they should, it’s time for fresh steel that’ll slice through crop residue and work the soil properly. This 18-inch smooth disc blade from Ingersoll gives you reliable cutting action for lighter tillage work, seedbed preparation, and finishing passes where you need a smooth, even cut without the aggressive action of notched blades.

What You’re Getting

Heavy-duty Boron 15B26 steel construction with 46-52 Rockwell hardness that holds an edge through acres of tough work
Standard 1.63-inch concavity design that moves soil effectively while maintaining proper cutting angle
Single punch hole mounting system for secure, wobble-free attachment to your disc gang
Quarter-inch thickness provides the right balance of durability and cutting performance for mid-size operations

Built for Real Farm Work

This blade fits disc harrows with 1-1/2 inch square axles, making it a perfect match for many mid-size tillage implements used for seedbed prep, residue management, and general cultivation. Whether you’re working corn stubble in the fall or preparing ground for spring planting, this smooth edge design gives you clean cutting action without being too aggressive for lighter soils or finishing work.

Made to Last

The Boron 15B26 steel maintains the perfect hardness range – hard enough to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. This material has proven itself in farm conditions and gives you the durability you need without breaking the budget.

Good to Know

This is a direct replacement blade – no modifications needed if your current setup uses 1-1/2 inch square axles. When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches.
