Notched Crimp Center Disc Blade for 22-Inch Harrow Applications with 1-1/2 Inch Round Axle

Description

When you’re working through heavy corn stalks or thick residue, a crimp center disc blade is your secret weapon. That notched edge cuts through tough stalks instead of just pushing them around, while the 6-inch crimp center design adds extra cutting points that help chop and size residue into manageable pieces. If you’ve been fighting plugging issues or dealing with long strips of material wrapping around your harrow, this blade design makes the difference between a smooth pass and a frustrating day in the field.

What You’re Getting

• Notched edge creates scissor action that slices through tough stalks other blades just bend over
• Six-inch crimp center adds additional cutting surfaces for better residue sizing
• Boron 15B26 steel maintains perfect hardness at 46-52 Rockwell – hard enough to hold an edge but not so brittle it shatters on rocks
• Quarter-inch thickness provides the beef needed for long service life in tough conditions
• Single punch mounting hole fits standard 1-1/2 inch round axles

Built for Real Farm Work

This 22-inch crimp center blade excels in high-residue conditions where regular blades struggle. In situations like continuous corn or after cover crops, that notched design makes the difference between effective residue management and a plugged-up mess. The crimp center design works especially well on disc harrows, cultivators, and vertical tillage tools where you need aggressive residue chopping combined with soil mixing action.

Made to Last

No fancy coatings here – just quality steel that works. The 2.5-inch concavity provides good soil throwing action while the quarter-inch thickness handles the punishment of rocks, roots, and heavy residue. Osmundson doesn’t mess around with blade materials, using steel that maintains its edge through acres of tough tillage.

Installation Notes

This blade mounts directly on 1-1/2 inch round axles with standard spacing. When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. Check your axle condition while you’re swapping blades – loose or worn axles cause premature blade wear and poor cutting performance.
