28 Inch Notched Disc Blade for 1-5/8 Inch Round Axle Disc Harrows

Description

When your disc blades start looking more like dull coins 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 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.

What You’re Getting

• Aggressive notched edge design creates scissor action that slices through tough stalks other blades just bend over
• Heavy-duty 8mm (5/16-inch) thickness provides the beef needed for long service life in tough conditions
• Premium Boron 15B26 steel at 46-52 Rockwell hardness holds an edge through acres of tough tillage but won’t shatter when you hit that hidden field stone
• Shallow 2.88-inch concavity gives you the right soil-throwing action for effective residue burial
• Single punch mounting for secure fit on 1-5/8 inch round axles

Built for Real Farm Work

This blade fits disc harrows using 1-5/8 inch round axles and excels in the demanding conditions you face every season. These notched blades excel in heavy residue conditions where you need aggressive cutting action, though they can be too aggressive in light soils or minimal trash conditions. Whether you’re working through corn stalks, bean stubble, or cover crops, this blade delivers the cutting power to break up tough material properly.

Made to Last

Osmundson doesn’t mess around with blade materials – this Boron steel maintains the perfect hardness range for long service life without fancy coatings, just quality steel that works. The 8mm thickness gives you the durability to handle rocks and hard ground conditions while maintaining sharp cutting edges season after season.

Good to Know

Check for elongated holes from wear – loose blades wobble and wear prematurely. Never mix worn and new blades on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips in your field. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches.
