SKU: SMA-114-223605P Smooth Disc Blade for Standard Tillage and Finishing Operations

When you're looking for a blade that finishes clean without being too aggressive, this 22-inch smooth disc blade delivers just the right balance. Whether you're doing secondary tillage after corn harvest or putting the finishing touches on a seedbed, this blade cuts through soil and light residue without the aggressive action that can leave your field looking like a war zone. It's the kind of blade that leaves a smooth, level finish that makes planting operations go a whole lot easier.

What You're Getting

• Smooth edge design provides clean cutting action without excessive soil throw
• High-quality Boron 15B26 steel construction that holds its edge through tough conditions
• 46-52 Rockwell hardness rating balances durability with workability
• 2.50-inch concavity creates proper soil mixing without over-aggressive tillage
• Single punch mounting fits standard 1-1/2 inch square axle harrows

Built for Real Farm Work

This blade fits disc harrows with 1-1/2 inch square axles, covering a wide range of tillage equipment from compact utility models to full-size field cultivators. At 22 inches, it's sized right for medium-duty tillage work where you need good penetration and mixing without the fuel-burning resistance of larger blades.

Made to Last

This 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 3/16-inch thickness provides good durability for most field conditions without adding unnecessary weight to your implement.

Good to Know

This is a direct replacement that mounts with the single punch hole system - no modifications needed. The single punch mounting means checking for elongated holes from wear - loose blades wobble and wear prematurely. When replacing blades, it's smart to do full gangs at once to maintain consistent cutting diameter across your implement.
