28 Inch Notched Disc Blade with Pilot Hole for Disc Harrows and Tillage Equipment

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 28-inch notched disc blade from Osmundson 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 pilot hole design gives you the flexibility to custom-fit this blade to your specific axle setup.

What You’re Getting

• Notched edge design creates scissor action that cuts through tough stalks instead of bending them over
• Pilot hole mounting gives you flexibility to fit various axle configurations and allows precise gang spacing
• Quality Boron 15B26 steel at 46-52 Rockwell hardness holds an edge through acres of tough tillage
• Standard 4.25-inch concavity throws soil aggressively to bury residue and level fields
• Heavy-duty 5/16-inch (8mm) thickness stands up to rocks and hard ground conditions

Built for Real Farm Work

This blade is sized for the big iron – the disc harrows and vertical tillage tools that cover serious ground in corn, soybean, and wheat country. It’s designed to turn stubborn crop residue into properly sized pieces instead of just pushing it around. In high-residue conditions like continuous corn or after cover crops, that notched edge makes the difference between effective residue management and a plugged-up mess that forces you to make extra passes.

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 5/16-inch thickness provides the beef needed for long service life while standing up to the punishment of heavy residue and rocky conditions.

Installation Notes

The pilot hole mounting means you’ll need to drill the center hole to match your specific axle size—measure twice, drill once. When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. Field-proven wisdom: Notched blades excel in heavy residue but can be too aggressive in light soils or minimal trash conditions.
