Description

When your old disc blades are worn to the point where they’re not cutting residue properly anymore, it’s time for blades that get back to business. This crimp center disc blade from Osmundson brings the specialized design your Case IH disc harrow needs to handle tough conditions. The crimp center design helps with soil mixing and residue incorporation while providing the reliability you need for long days in the field.

What You’re Getting

22-inch diameter with 1-1/2 inch round axle fit for reliable mounting
7 gauge thickness (4.5mm) strikes the right balance between durability and weight
Smooth edge design for consistent cutting and finishing passes
Crimp center construction adds strength and helps with soil flow
Boron 15B26 steel with 46-52 Rockwell hardness for long-lasting performance

Built for Real Farm Work

This blade fits Case IH 496 disc harrows as well as the 3800, 3850, 3900, and 3950 series disc harrows. These are workhorse machines used for primary tillage, seedbed preparation, and residue management across all types of farming operations. Whether you’re working corn stubble, preparing ground for spring planting, or breaking up compacted soil layers, this blade handles the load.

Made to Last

Osmundson builds these blades with quality Boron steel that holds up to rocks, roots, and whatever else your fields throw at them. The crimp center design isn’t just for looks – it adds structural strength while helping move soil more effectively than standard flat blades. The single punch mounting hole ensures proper fit without the complexity of multiple mounting points.

Good to Know

Installation is straightforward – just make sure your axle diameter matches the 1-1/2 inch round specification. When replacing blades, it’s smart to do full gangs at once rather than mixing worn and new blades, as the diameter difference can cause uneven cutting. Keep an eye on blade diameter – when you’ve lost 3-4 inches from the original size, it’s time for new ones.
