Description

When your disc blades start looking more like smooth wheels than cutting tools, it’s time for replacements that’ll actually slice through residue instead of just pushing it around. This 22-inch notched disc blade brings aggressive cutting action back to your disc harrow, turning tough corn stalks and matted residue into properly sized pieces that’ll break down instead of hair-pinning around your planter next spring.

What You’re Getting

22-inch diameter with aggressive notched edge design that slices through tough crop residue
Quarter-inch thick boron steel construction rated 46-52 Rockwell hardness for long-lasting cutting performance
Combo hole design fits 1-1/8 square by 1-1/4 square axles on John Deere and similar disc harrows
Standard 2.5-inch concavity provides proper soil mixing and residue burial
Heavy-duty construction that handles rocks, roots, and hard-packed ground without chipping

Built for Real Farm Work

This blade fits John Deere disc harrows and other machines running the 1-1/8 by 1-1/4 inch square axle setup. Whether you’re working down corn ground after harvest or breaking up pasture for reseeding, these notched blades attack residue aggressively. Each notch creates a scissor action that cuts through tough stalks other blades just bend over.

Made to Last

Built from high-carbon boron steel that’s heat-treated for durability, this blade keeps its cutting edge season after season. The quarter-inch thickness gives you plenty of material to work with as the blade wears, and the 46-52 Rockwell hardness rating means it stays sharp through rocks and roots without getting brittle.

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 blades on rear gangs for finishing. When storing your disc harrow, coat blade edges with used oil to prevent rust pitting that ruins cutting ability. Track blade wear by measuring diameter annually – most blades are done when they’ve lost 3-4 inches from their original size.
