Overview
The Black & Decker GH3000 High Performance 7.5A 14 in. Electric String Trimmer/Edger is built for homeowners who want corded power, clean edging, and straightforward operation without stepping up to a gas machine. This is a string trimmer and lawn edger designed for trimming grass, knocking down weeds, and cleaning up edges along sidewalks and driveways. Model Number GH3000. If you want a plug-in yard tool that starts instantly and keeps working as long as you have extension cord reach, this one makes sense.
On the job, the numbers are right where they need to be for routine property maintenance. The 7.5 amp motor and gear drive transmission are there for tougher grass and overgrowth, while the 14 inch cutting swath helps you cover more ground with each pass. It has a top speed of 7,500 RPM, which helps explain why this unit is positioned as Black & Decker's higher-performing corded weed trimmer in this size class. The single 0.080 inch line is a common, easy-to-source size that balances cutting performance with manageable line use.
One of the real selling points here is how the GH3000 handles the switch from trimming to edging. The Groom N' Edge quick latch setup lets you move from open-area trimming to vertical edge work without wasting time. Black & Decker also adds a wheeled edge guide, which matters more than it sounds. When you're running along a sidewalk or driveway, that wheel helps keep the head tracking the line instead of wandering, so your edge looks cleaner and you do not chew up as much line.
For day-to-day use, this trimmer is aimed at comfort more than brute-force landscaping. The curved shaft, adjustable height, and pivoting handle make it easier to set the tool up for your stance instead of forcing you to work around the tool. At 6.9 pounds, it stays light enough for most homeowners to use for regular cleanup without the arm fatigue that shows up fast on heavier outdoor power equipment. The corded setup also means no fuel mixing, no carburetor issues, and no waiting on charging.
The Automatic Feed Spool system is another practical feature that helps this tool stay homeowner-friendly. Instead of bump feeding, the AFS system advances line as needed, so you can stay focused on your cut path rather than stopping to fuss with the spool. That is especially helpful when you are moving between grass density changes or trimming around landscape beds, fences, and hardscape where line wear picks up.
As an outdoor power tool, the Black & Decker GH3000 High Performance 7.5A 14 in. Electric String Trimmer/Edger is a good fit for homeowners, DIY yard care, and routine lawn maintenance around small to mid-size properties. It is best for grass trimming, border cleanup, and regular edging work, not clearing heavy brush like a dedicated brush cutter. If your priority is easy startup, steady corded runtime, and a clean lawn edge without spending much time learning the tool, this model earns its keep.
Clean Up Lawn Edges Without a Separate Edger

This tool is built for the kind of yard work most people actually do every week: trimming open grass, then tightening up the border when the job is almost done. The quick conversion from trimmer to edger saves time and cuts down on tool changes.
- Groom N' Edge quick latch release switches from trimming to edging in seconds
- Wheeled edge guide helps track straighter along sidewalks and driveways
Keep Working Without Bump Feeding

When line feed works right, yard work goes smoother. The AFS automatic feed system is designed to advance line when needed, so you are not tapping the head on the ground every few minutes just to keep cutting.
- Uses 0.080 inch single line for trimming grass and weeds
- Comes with one SF-080 spool already installed
Hold a Straighter Line Along Concrete

Edging is where a lot of light-duty trimmers get sloppy. The curved shaft layout and wheel-guided edging setup help this unit stay more controlled when you are cleaning borders against hardscape.
- 14 inch cutting path covers ground quickly on regular lawn maintenance
- Curved shaft design supports controlled edging and trimming around obstacles

Pro Tip
When you are edging against concrete, use the wheeled guide and keep the head tracking the edge instead of forcing the line into the pavement. You will get a cleaner line and burn through a lot less 0.080 inch trimmer line.
