71-85716 3-Point 9" Length Edger Blade Compatible with Craftsman Gas Edgers & Edger Trimmers - Replaces 71-85716 85716 1/2" Center Hole Blade

What It Is

This is a 9-inch 3-point edger blade designed for Craftsman gas edgers and edger trimmers. It cuts a clean edge along driveways, sidewalks, and flower beds, replacing OEM part numbers 71-85716 and 85716.

Fitment & Compatibility

Before buying, confirm your edger uses a 3-point mounting system (three bolts or screws attach the blade to the hub). Measure the center hole: this blade has a 1/2-inch center hole. Check your blade’s length—if it’s 9 inches, this is a direct swap. Compatible with most Craftsman gas edger models (e.g., 536.772, 536.773 series) and some edger trimmers. Verify your model number against the OEM 71-85716 or 85716 part list. Not for universal fit—avoid if your edger uses a single-bolt or keyhole mount.

Key Things to Know

• Quality: Made from hardened steel; holds an edge well but may dull faster on rocky or sandy soil.
• Installation: Easy—remove the old blade, align the three holes, and tighten bolts to 30-40 ft-lbs. Wear gloves; edges are sharp.
• Common gotcha: The 3-point pattern must match your hub exactly. If your blade has a different number of mounting holes or a larger center hole (e.g., 5/8"), this won’t fit.
• Replacement frequency: Replace when nicked or bent; typically every 1-2 seasons with regular use.

Should You Buy It

If you own a Craftsman gas edger with a 3-point mount and a 1/2-inch center hole, this is a reliable, low-cost replacement that matches OEM specs. Skip it if your edger uses a different mounting system or you need a longer blade for deeper cuts.
