Notched Disc Blade with Wear Tuff Coating for Disc Harrows with 1-1/2 Inch Square Axle

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 24-inch notched disc blade brings aggressive cutting action back to your 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. The Wear Tuff coating adds an extra layer of protection that extends blade life even further.

What You’re Getting

• Aggressive notched edge that creates scissor action to cut through tough stalks instead of bending them over
• Premium Wear Tuff coating for extended blade life and superior wear resistance
• Quality Boron 15B26 steel hardened to 46-52 Rockwell for the perfect balance of edge retention and toughness
• Standard 2.80-inch concavity that throws soil aggressively to bury residue and level fields
• Single punch mounting for secure, wobble-free operation

Built for Real Farm Work

Your disc harrow needs to do more than just roll over crop residue – it needs to cut, size, and mix that material into the soil profile. These notched blades attack residue aggressively, with each notch creating a scissor action that slices through tough stalks other blades just bend over. They’re particularly effective in heavy residue conditions like continuous corn or after cover crops where you need that extra cutting power.

Made to Last

Osmundson doesn’t mess around with blade materials. 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 Wear Tuff coating provides an additional layer of protection against abrasive soils and extends the working life of your investment.

Installation Notes

The single punch mounting means checking for elongated holes from wear – loose blades wobble and wear prematurely. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches. Consider replacing blades as complete gang sets for even cutting performance.
