9 inch Edger Blade 638006008 638006007 with Teeth Compatible with Ryobi RY13050 RY13050A RY15518 RY40030, Heavy-Duty Blade 9'' Length, 1" Center Hole, 3 Pack

What It Is

This is a heavy-duty 9-inch edger blade with teeth, designed for Ryobi string trimmers/edgers. It replaces OEM part numbers 638006008 and 638006007, cutting through tough grass and light weeds along driveways, sidewalks, and garden borders.

Fitment & Compatibility

Before buying, confirm your machine matches these specs:

• Blade length: 9 inches (center to tip)
• Center hole: 1 inch diameter
• Compatible Ryobi models: RY13050, RY13050A, RY15518, RY40030 (check your model number on the unit’s sticker)
• Not compatible with other brands or Ryobi models not listed; measure your existing blade’s length and hole size to be certain.
• OEM vs aftermarket: This is a direct replacement, not a Ryobi OEM part, but it matches factory dimensions.

Key Things to Know

• Installation: Easy – remove the old blade, align the 1-inch hole, and tighten the nut. No special tools needed beyond a wrench.
• Durability: Heavy-duty steel with teeth lasts longer than standard blades on rocky or compacted soil, but avoid hitting large rocks or concrete edges.
• Common gotcha: Ensure the blade is seated flat and the retaining nut is torqued to spec (check your manual). A loose blade can wobble or detach.
• 3-pack value: Buying a 3-pack saves you from frequent replacements; rotate or replace as teeth dull.

Should You Buy It

If you own one of the listed Ryobi models and regularly edge hard surfaces or thick turf, this 3-pack is a solid, affordable upgrade. It’s a straightforward swap, lasts longer than basic blades, and the high rating (4.7/5) reflects consistent performance. Not for light-duty trimmers or non-Ryobi machines.
