71-85716 3-Point 9" Edger Blade, Compatible with Crafts Man Gas Power Edgers & Edger Trimmers, 85716 1/2" Center Hole Blade Fit for 536772300 536772301 536772340, Replace 71-85716 85716

What It Is

This is a 9-inch 3-point edger blade (model 71-85716) designed to replace the factory blade on Craftsman gas-powered edgers and edger trimmers. It cuts a clean trench along sidewalks, driveways, and garden beds by spinning vertically against the ground.

Fitment & Compatibility

Before buying, confirm these three things:

• Center hole size: Must be 1/2-inch. This blade fits only edgers with a 1/2-inch arbor.
• Mounting pattern: 3-point (three bolt holes around the center). Count your current blade’s holes.
• Model numbers: Directly replaces OEM part 85716. Fits Craftsman models 536772300, 536772301, and 536772340. Also works on many other Craftsman gas edgers with the same 3-point, 1/2-inch arbor setup.

Do not assume universal fit – measure your old blade’s center hole and bolt pattern. This is not for electric edgers or string trimmers.

Key Things to Know

• Steel quality: Aftermarket blade made from hardened steel. Holds an edge well but will dull faster than OEM if hitting concrete regularly.
• Installation: Easy – remove the nut holding the old blade, swap, and torque to spec (typically 30-40 ft-lbs). No special tools beyond a socket wrench.
• Common gotcha: The 9-inch diameter may be slightly larger or smaller than your original. Double-check clearance inside the edger guard before tightening.
• Balance: Inspect for warping out of the box – spin it by hand after mounting to ensure it runs true.

Should You Buy It

If you have a compatible Craftsman gas edger and need a budget-friendly replacement that works as well as the OEM part, this blade is a solid buy at $10.99. It’s ideal for homeowners who edge a few times per season and want to save money. For heavy commercial use or constant concrete contact, expect shorter life than a factory blade.
