AC053N1FB Serrated Blade Replacement for Ryobi 3-in-1 Fixed String Trimmer Head 10-Pack

What It Is

This is a 10-pack of serrated replacement blades for the Ryobi 3-in-1 fixed string trimmer head (model AC053N1FB). Designed for brush-clearing and heavy weeds, not for standard lawn edging.

Fitment & Compatibility

• Exact fit: Ryobi 3-in-1 fixed trimmer head (AC053N1FB) only – not for bump-feed or universal heads.
• Check your head: Look for the three-blade metal hub with a center bolt; if your head uses string or a single blade, these won’t work.
• OEM vs aftermarket: These are aftermarket. OEM Ryobi blades (part #AC053N1FB) are identical in shape and size. Measure your existing blade length (approx. 3.5 inches) to confirm.
• Machine compatibility: Fits any Ryobi trimmer that uses the 3-in-1 head (e.g., 40V and 18V brushless models with that specific head). Verify your model number in the manual.

Key Things to Know

• Quality variance: At $9.99 for 10, expect thinner steel than OEM. Blades may dull faster in rocky soil or against fence posts.
• Installation: Easy – remove center bolt, swap blade, re-torque to manufacturer spec (usually 15-20 ft-lbs). No tools beyond a socket wrench.
• Common gotcha: The serrated edge is aggressive. Do not use near sidewalks, patios, or delicate plants – it will chip concrete and shred soft bark.
• Pack size: 10 blades = roughly 2-3 seasons of normal use for a 1/4-acre property. Store dry to prevent rust.

Should You Buy It

Buy this if you have the Ryobi 3-in-1 fixed head and regularly cut through thick brush, blackberries, or overgrown weeds. Skip it if you mow only grass – standard string is cheaper and less damaging to your yard. For the price, it’s a solid budget option for heavy-duty clearing, but don’t expect OEM longevity.
