16" Smooth/Plain Disc Harrow Blades for International

What It Is

This is a 16-inch smooth/plain disc harrow blade designed for ground-engaging equipment like tillers, disc harrows, or older International-brand tractors used in light soil cultivation or landscaping prep—not a standard lawn mower blade.

Fitment & Compatibility

• Deck/Equipment Size: Fits disc harrows or attachments with a 16-inch blade diameter requirement. Measure existing blade diameter precisely.
• Model/Brand Fit: Listed for International, but aftermarket; may fit other brands (e.g., Ford, Ferguson) if hub hole pattern matches. Verify your equipment’s model number.
• OEM vs Aftermarket: Aftermarket replacement. Check if original was smooth/plain (some require notched blades for heavy soil).
• Key Measurements: Measure the center hole diameter (typically 1-1/8" to 1-1/4") and arbor bolt pattern. Confirm blade thickness (usually 1/4" or 3/16"). Ensure square or round center hole matches your hub.

Key Things to Know

• Quality: Smooth edge is fine for light soil, but won’t cut through heavy clay or roots as well as notched blades.
• Installation: Moderate difficulty—requires removing hub nuts and possibly a puller if rusted. Use anti-seize on bolts.
• Gotcha: These are not mower blades; they’re for ground engagement. Installing on a lawn mower deck is unsafe and won’t work.
• Durability: Carbon steel is typical; expect wear over time in abrasive soil. Hardened versions last longer but cost more.

Should You Buy It

Buy this if you need a budget-friendly replacement for a 16-inch smooth disc blade on an older International or compatible disc harrow for light-duty tilling or leveling. Skip it if you need notched blades for tough soil, or if your equipment requires OEM-specific dimensions.
