Best Electric Edgers for Lawns: Five Options for Clean, Defined Borders
The best electric edger for your lawn depends on whether you prioritize cordless mobility, trenching capability, or steady corded power. The Greenworks 40V is best for cordless edging with a brushless motor, while the 20V 2-in-1 model suits buyers who also want a string trimmer. For trenching and adjustable cuts, consider the 20V cordless trencher or the corded WORX and BLACK+DECKER models. Compare their listed features below, then choose based on your yard and power needs.

20V 2-in-1 Cordless String Trimmer and Edger
Best for: Homeowners who want an edger and string trimmer in one tool. Its listed name identifies it as a 20V cordless, 12-inch, 2-in-1 model, making it a relevant choice when reducing the number of separate lawn tools matters.
Choose this if you want to switch between trimming and edging with a single product. The available product details do not specify battery capacity, runtime, or adjustment options, so check the listing for those details before deciding. It may be less suitable if you need confirmed trenching features or detailed cutting-depth controls.
20V Cordless Edger and Trencher
Best for: Buyers who want cordless edging plus the ability to cut trenches. The listed package includes a 4.0Ah battery and charger. Its 2-in-1 design is intended for trimming lawn borders and making trenches for landscape lighting wires.
The product lists a 3500 RPM motor, a 9-inch metal blade, four cutting-height settings, and a maximum cutting depth of 1.75 inches. A three-position parallel guide allows adjustment for different edging situations. Choose this over a basic edger if trenching and selectable settings are priorities. The listed maximum depth may not meet needs requiring deeper trenches.
WORX WG896 12-Amp Electric Edger
Best for: Shoppers looking for a corded edger that is also described as a trencher. The WG896 listing specifies a 12-amp motor and a 7.5-inch trencher, offering a clear choice for buyers who prefer a corded tool over battery-powered equipment.
Choose this if you want those stated power and trencher specifications. A corded tool requires access to an outlet and cord management while working; it is less convenient when edging far from power. The supplied product details do not list blade adjustment settings or cutting depth.
BLACK+DECKER LE760FF 12-Amp Edger
Best for: Buyers who want a corded 2-in-1 tool with multiple height settings. The listed model has a 12-amp motor, a 7.5-inch cutting width, and three height settings. Its edger-and-trencher design suits landscaping tasks beyond shaping a simple lawn border.
Choose this if adjustable height and trenching are priorities. As a corded model, it is less convenient where an outlet is not close to the work area. The available details do not specify maximum trench depth, so confirm that information if trenching is central to your project.
Greenworks 40V Cordless Lawn Edger
Best for: Buyers who want cordless edging and a steel blade for borders along driveways, sidewalks, patios, and landscaping. The listed package includes a 4.0Ah battery and charger. Its 40V brushless motor is described as providing cutting power, quieter operation, and less motor wear.
The 8-inch steel blade is intended for precise edging and cutting through grass and compacted soil. Choose this over a 2-in-1 trimmer if dedicated edging is the priority. The listed features do not provide runtime or adjustable-depth information, so compare those details if they matter for your yard.
Buying Guide: How to Choose an Electric Lawn Edger
Should you choose cordless or corded?
Cordless models avoid managing a power cord around sidewalks and landscaping. Compare battery voltage and included battery capacity, but remember that the listed specifications here do not establish runtime. Corded models provide a direct-power option, but the cord can limit reach and requires care during use.
Do you need an edger, a trencher, or both?
A standard edging task creates a defined border where lawn meets a driveway, path, or garden bed. A trencher is intended to cut a channel, such as one for landscape-lighting wires. If trenching matters, look for an explicit 2-in-1 designation and check the stated cutting depth rather than assuming every edger can dig a trench.
Which blade and adjustment details matter?
Blade diameter helps describe the cutting width, while adjustable height or depth settings help tailor a cut. Compare the 8-inch Greenworks blade with the 9-inch blade on the cordless 20V trencher and the 7.5-inch specifications on the corded models. Blade size alone does not establish which tool is best for every lawn.
What should you verify before buying?
Confirm what comes in the package, including a battery and charger for cordless tools. Check whether the listed settings fit your edging style and whether the tool is designed for trenching. For corded equipment, consider outlet location and cord reach. Consult the product listing for any specifications not provided here, including runtime, depth, and included accessories.
Frequently Asked Questions
What is an electric lawn edger used for?
An electric lawn edger cuts a defined line along lawn borders, such as where grass meets a sidewalk, driveway, or planting area.
Can a lawn edger also dig trenches?
Some models are marketed as edger-trenchers. Check the product description and maximum cutting depth to confirm whether a particular model suits your trenching task.
Is a cordless edger better than a corded edger?
A cordless edger offers freedom from a power cord, while a corded model needs access to an outlet. The better choice depends on your yard layout and preference for battery or corded power.
Does a larger blade always cut better?
No. Blade size is one specification to compare, but the right tool also depends on the task, cutting adjustments, and whether you need edging or trenching.
Should I buy an edger that doubles as a string trimmer?
A 2-in-1 tool may suit buyers who want both functions in one product. Choose a dedicated edger instead if its stated blade, depth, or trenching features better match your work.
