SKU: SMA-114-305611RSP Smooth Disc Blade for Rome Disc Harrows with Round Axle

When you're running your Rome or Tatu disc harrow and notice it's not cutting through residue like it used to, chances are your blades have worn down enough that they're just pushing trash around instead of slicing through it. A worn disc blade will leave you with uneven seedbeds and chunks of crop residue that'll cause headaches come planting time. This 30-inch smooth disc blade gets your harrow back to doing what it does best—cutting clean and preparing a proper seedbed.

What You're Getting

• 30-inch diameter with smooth edge design for clean cutting and soil finishing
• 3.3-inch shallow concavity that moves soil efficiently without being too aggressive
• Heavy-duty Boron 15B26 steel construction with 46-52 Rockwell hardness for long wear life
• Single punch mounting hole with 1-5/8 inch round axle fit—direct replacement, no modifications needed
• 5/16-inch thickness provides the strength to handle rocks and tough conditions without cracking

Built for Real Farm Work

This blade is specifically designed for Rome and Tatu disc harrows, equipment that's built to handle everything from spring tillage to fall residue management. Whether you're working corn stubble, preparing ground for soybeans, or doing final seedbed prep, this blade delivers the consistent cutting action these harrows are known for. The shallow concavity works well in a variety of soil types without being overly aggressive.

Made to Last

The Boron steel construction means this blade will hold its edge through season after season of tough fieldwork. The 46-52 Rockwell hardness strikes the right balance—hard enough to cut through roots and stalks cleanly, but not so brittle it'll chip when you hit that inevitable rock or fence post remnant. The smooth edge design also means less stress concentration compared to notched blades, which translates to longer service life.

Installation Notes

This is a direct replacement for your worn Rome disc blades—same mounting hole, same axle size, same concavity. When replacing blades, it's best to do the whole gang at once rather than mixing new and worn blades, since the diameter difference will give you uneven cutting. Check your spool spacing while you've got things apart, and don't forget to grease those bearings while they're accessible.
