Description

When your disc harrow blades start looking more like smooth wheels than cutting tools, it’s time for a replacement that’ll actually slice through the soil instead of just rolling over it. This 18-inch smooth disc blade brings clean cutting action back to your harrow, breaking down crop residue while creating an even, smooth finish that’s perfect for seedbed preparation and final tillage passes.

What You’re Getting

Made from quality Boron 15B26 steel with 46-52 Rockwell hardness that holds an edge through acres of tough tillage work
Standard 1.63-inch concavity that throws soil properly for effective mixing and leveling
3/16-inch thickness provides the right balance of durability without being overly aggressive
Single punch mounting hole fits standard disc harrow gangs with proper spacing

Built for Real Farm Work

This blade fits any disc harrow running 1-1/8 inch square axles, from compact utility tractors to mid-size row-crop machines. Whether you’re working corn ground after harvest, preparing wheat stubble for the next crop, or smoothing up pastures, this smooth edge design gives you the clean cut you need without the aggressive action of notched blades.

Made to Last

The Boron steel maintains perfect hardness – hard enough to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. No fancy coatings here – just quality steel that works.

Good to Know

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. At 18 inches starting diameter, you’ve got good life ahead if maintained properly.
