SKU: SMA-114-223603FN Crimp Center Notched Disc Blade for Disc Harrow Gang Assemblies

When your disc harrow's blades start pushing residue instead of cutting through it, you know it's time for fresh metal that'll actually do the job. This crimp center disc blade brings back the aggressive cutting action you need to slice through tough corn stalks, matted cover crops, and heavy residue that's clogging up your operation.

What You're Getting

• 22-inch diameter with notched edge design for aggressive residue cutting and soil mixing
• Crimp center construction with 6-inch diameter center for improved strength and durability
• 3/16-inch thickness in high-carbon Boron 15B26 steel with 46-52 Rockwell hardness
• 1-1/8 inch square axle hole with single punch mounting for secure, wobble-free operation
• Standard 2.50-inch concavity that moves soil effectively while burying crop residue

Built for Real Farm Work

This blade fits disc harrows with 1-1/8 inch square axle spacing, making it perfect for a wide range of tillage equipment used in primary and secondary tillage operations. Whether you're working corn ground, preparing seedbeds, or incorporating crop residue, the crimp center design provides extra structural integrity where standard blades might flex or crack under heavy loads.

Made to Last

The 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 crimp center adds reinforcement right where stress concentrates, helping the blade maintain its shape and cutting efficiency longer than standard flat disc designs.

Good to Know

Installation is straightforward with the single punch hole design - just remove the old blade and mount the new one with your existing hardware. When replacing blades, never mix worn and new on the same gang - the diameter difference creates uneven cutting that leaves mohawk strips. The single punch mounting means checking for elongated holes from wear - loose blades wobble and wear prematurely. A quick tip: measure your current blade diameter before ordering to ensure you're getting the right replacement size.
