SKU: SMA-114-281405FP Smooth Crimp Center Disc Blade for Heavy-Duty Agricultural Disc Harrows - 28 Inch

When you're running a big disc harrow and need to cover serious ground while still getting a good finish, the crimp center design makes all the difference. This 28-inch smooth blade gives you that aggressive soil-throwing action in the center where the crimp is, but still leaves a nice finish for your seedbed prep. It's the kind of blade you want when you're working heavy residue fields but don't want the ground looking like a war zone afterward.

What You're Getting

• 28-inch diameter provides excellent soil penetration and coverage for heavy-duty tillage operations
• Crimp center design creates aggressive soil movement while the smooth outer edge finishes clean
• Quality Boron 15B26 steel construction with 46-52 Rockwell hardness that holds an edge through tough conditions
• 1/4-inch thickness gives you the strength needed for years of hard work without premature wear
• Single punch mounting hole fits 1-1/2 inch square axles - direct replacement installation

Built for Real Farm Work

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 1/4-inch thickness provides the beef needed for long service life, while that 8-inch crimp center creates the soil-moving action that buries residue and levels out tire tracks and hoofprints.

Made to Last

This blade's built to handle whatever your farm throws at it - from rocky ground to heavy clay to fields littered with corn stalks. The smooth edge works great in lighter residue conditions and many operators run smooth blades on rear gangs for finishing. No coatings or gimmicks here, just proven steel that keeps working season after season.

Good to Know

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: coat blade edges with used oil to prevent rust pitting that ruins cutting ability when storing your harrow.
