BLACK+DECKER String Trimmer / Edger, 13-Inch, 5-Amp (ST8600)

What It Is

The BLACK+DECKER ST8600 is a 5-amp electric string trimmer and edger with a 13-inch cutting swath, designed for residential lawn trimming and edging along sidewalks and driveways.

Fitment & Compatibility

This is a complete trimmer/edger unit, not a replacement part. It’s designed for homeowners with small to medium yards (under 1/4 acre). No additional machine compatibility needed—it’s a standalone tool. Before buying, ensure your outdoor power source is within reach of a 100-foot extension cord (minimum 14-gauge, outdoor-rated). The 5-amp motor requires a standard 120V outlet. No deck size or model fitment checks are needed; this is the full tool.

Key Things to Do

• Check the cord: Use a heavy-duty, outdoor-rated extension cord (14-gauge or thicker) for 100-foot runs to avoid voltage drop and motor strain.
• Install the included spool correctly: The bump-feed head is pre-wound with .065-inch line. If replacing, use only BLACK+DECKER AF-100 or compatible .065-inch line to avoid jamming.
• Convert between trimming and edging: The head rotates 180° and locks in place with a button—no tools required. Make sure the locking mechanism clicks fully before use.
• Watch for line feed issues: The bump-feed can be finicky if the head is dirty or the line is too short. Clean the head regularly and rewind evenly.

Should You Buy It

Buy the ST8600 if you need a reliable, lightweight electric trimmer for small-to-medium yards and prefer corded power over battery hassle. It’s a strong value at $59, with solid performance for edging and trimming. Skip it if your yard is larger than 1/4 acre or you need cordless convenience.
