8 in. Replacement Edger Blade

What It Is

This is an 8-inch replacement blade designed for gas and electric edgers (not lawn mower decks). It trims grass along sidewalks, driveways, and flower beds, cutting vertically to create clean edges.

Fitment & Compatibility

Before buying, check three things:

• Blade size: Must be exactly 8 inches in diameter (not 7, 9, or 10 inches). Measure your current blade or check your edger’s manual.
• Shaft/arbor hole: Most edgers use a 1-inch arbor hole, but some are 7/8-inch or 20mm. Measure the hole diameter or match the center hole shape (round vs. D-shaped).
• Mounting pattern: This blade uses a standard 3-bolt pattern (holes spaced 120° apart). Confirm yours matches—some edgers use a single center bolt or a different bolt circle.

Brand-specific fitment: Compatible with many Troy-Bilt, Craftsman, Husqvarna, Echo, and Ryobi edgers, but not universal. If your edger uses a proprietary blade (e.g., Black & Decker’s “edger blade” with a unique hub), this won’t work.

Key Things to Know

• Quality: Made from heat-treated steel for durability, but it’s a budget blade. Expect decent performance for residential use; not for heavy commercial abuse.
• Installation: Easy—remove old blade, align holes, tighten bolts to 30-40 ft-lbs. Use a torque wrench if possible. Over-tightening can warp the blade.
• Sharpening: Can be sharpened with a file or grinder, but replacement is cheap enough that many just swap it.
• Common gotcha: The blade is reversible—one side dulls, flip it for double the life. Mark the dull side with a Sharpie to track usage.

Should You Buy It

Yes, if you need a reliable, low-cost 8-inch edger blade for standard gas or electric edgers with a 1-inch arbor and 3-bolt mount. It’s a no-frills replacement that fits most popular brands and delivers good value for occasional home use. Skip it if you have a proprietary edger or need commercial-grade tungsten-carbide tips.
