Description
When you’re looking at worn blades that barely cut residue anymore, it’s time for replacements that’ll actually do the job. This 20-inch smooth disc blade brings the cutting action back to your tillage operation, slicing through crop residue cleanly instead of just pushing it around. The smooth edge provides clean cutting without the aggressive action that some conditions don’t need.
What You’re Getting
- Premium Boron 15B26 steel construction with 46-52 Rockwell hardness for long-lasting edge retention and durability
- Standard 2-inch concavity provides proper soil flow and self-cleaning action in most field conditions
- Single punch mounting hole makes installation straightforward—no complex bolt patterns to figure out
- Quarter-inch (6.0mm) thickness gives you the right balance of strength and weight for most disc harrow applications
Built for Real Farm Work
This blade fits disc harrows and tillage equipment using 2-inch round axles, which covers a wide range of older and mid-sized implements. Whether you’re working corn stubble, breaking up sod, or preparing seedbeds, smooth blades excel where you need clean cutting without the aggressive residue chopping that notched blades provide.
Made to Last
Ingersoll builds these blades from heat-treated Boron steel that’s specifically formulated for disc blade applications, with hardness that holds a sharp edge through rocks and tough conditions but won’t chip or crack under impact. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches from the original 20-inch size.
Good to Know
The single punch mounting means checking for elongated holes from wear—loose blades wobble and wear prematurely. When replacing blades, never mix worn and new on the same gang since the diameter difference creates uneven cutting. When storing your disc harrow, coat blade edges with used oil to prevent rust pitting that ruins cutting ability.
