Description

When your disc blades start looking more like smooth rollers than cutting tools, it’s time for replacements that’ll actually cut through crop residue instead of just pushing it around. This 20-inch notched disc blade brings back the aggressive cutting action your harrow needs, slicing through tough corn stalks and tangled residue that worn blades just roll over.

What You’re Getting

Aggressive notched edge design that creates a scissor action to slice through residue other blades just bend
Premium Boron 15B26 steel that holds its edge through seasons of tough tillage work
Proper 46-52 Rockwell hardness – hard enough to stay sharp but won’t shatter when you hit that hidden rock
Standard 1.88-inch concavity that moves soil properly while maintaining good penetration
Single punch mounting for secure attachment to your harrow gang

Built for Real Farm Work

This blade fits any disc harrow running 1-1/2 inch square axles with standard spacing. Whether you’re breaking up corn ground in the fall, working bean stubble, or preparing a clean seedbed for spring planting, this blade handles the job. The notched edge excels in heavy residue conditions where smooth blades struggle.

Made to Last

This Boron 15B26 steel maintains the perfect hardness range – hard enough at 46-52 Rockwell to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. The 3/16-inch thickness provides the right balance of durability and soil penetration for most tillage operations.

Good to Know

Notched blades excel in heavy residue but can be too aggressive in light soils or minimal trash conditions. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing. When replacing blades, swap out the entire gang at once – mixing worn and new blades creates uneven cutting that leaves strips in your field.
