787-01503-0637 Edger Blade Replacement for MTD, Crafstman, Troy-Bilt 25A-515-966, 25B-515-966, 316772380, 25B-515-799

What It Is

This is a replacement edger blade designed for MTD, Craftsman, and Troy-Bilt trimmer-style edgers. It fits models such as the 25A-515-966, 25B-515-966, 316772380, and 25B-515-799, and is used for cutting clean edges along driveways, sidewalks, and flower beds.

Fitment & Compatibility

Before buying, confirm your edger’s model number (found on the unit’s sticker) matches one of the listed models: 25A-515-966, 25B-515-966, 316772380, or 25B-515-799. This blade is OEM (original equipment from Troy-Bilt), so it’s a direct replacement—no aftermarket adaptation needed. The blade measures approximately 7.5 inches in diameter with a 1-inch center hole and a 0.125-inch thickness. Do not assume it fits other edger brands or models; check your owner’s manual or measure your current blade’s hole size and diameter.

Key Things to Know

• Quality: Made of stamped steel with a sharpened edge—durable for residential use but may dull faster on heavy-duty concrete or stone edging.
• Installation: Easy to swap with a single bolt and washer; you’ll need a socket wrench. No special tools required.
• Common Gotcha: The blade is directional—ensure the cutting edge faces the correct rotation direction (usually marked with an arrow) to avoid poor cuts or vibration.
• Safety: Always disconnect the spark plug or battery before replacing the blade to prevent accidental startup.

Should You Buy It

If you own one of the listed MTD, Craftsman, or Troy-Bilt edger models and need a direct OEM replacement for residential lawn edging, this blade is a reliable, low-cost choice. It’s not ideal for heavy commercial use or non-compatible edgers—measure first.
