SKU: SMA-114-221406FP Smooth Crimp Center Disc Blade for Vertical Tillage and Conservation Practices

When you're working ground with vertical tillage tools or trying to size residue without completely burying it, this crimp center blade gives you the control you need. The raised center section grabs and fractures crop residue while the smooth outer edge provides clean cutting action—perfect for those times when you want to prepare a seedbed without losing all that valuable surface protection.

What You're Getting

• 6-inch crimp center design that aggressively sizes residue while maintaining soil structure
• Smooth outer edge for clean cutting without excessive soil disturbance
• Boron 15B26 steel hardened to 46-52 Rockwell for long-lasting performance
• 1/4-inch thickness provides durability while maintaining proper blade dynamics
• Single punch mounting hole for secure, wobble-free operation

Built for Conservation Tillage

This blade excels in vertical tillage equipment and conservation practices where you need to size residue without creating a plowed appearance. The crimp center design is particularly effective on corn stalks and soybean stubble, breaking them down to manageable sizes while leaving enough surface coverage for erosion protection. It's also great for spring residue management when you need to warm the soil but keep some trash on top.

Made to Handle the Load

The Boron steel construction gives you the perfect balance—hard enough to hold an edge through tough conditions but won't shatter when you hit that hidden rock. The 2.50-inch concavity provides good soil flow while the crimp center adds the aggressive action needed to handle heavy residue loads without plugging.

Installation Notes

This is a direct replacement that mounts with the standard single punch hole design. Check for elongated holes from wear when replacing—loose blades wobble and wear out faster. Never mix worn and new blades on the same gang since diameter differences create uneven cutting.
