What is a cordless lawn edger?

Cordless lawn edgers are electric tools that create tidy landscaping borders with limited manual labor. These impressive machines enable homeowners to manicure the edges around their lawn and garden elements to achieve professional quality results.

Most edgers boast a rotating blade that slices through grass and dirt. Many modern lawn edgers can also function as corded weed whacking devices.

What are the different types of lawn edgers?

String Trimmers

String trimmers cut the grass and weeds that grow in areas where lawn mowers cannot reach. They are used to cut around fence posts, trees, pushes, and other lawn and garden elements.

If you’re looking to cut such grass and weeds, check out my informative post on how to use a string trimmer.

Lawn Edgers

Lawn edgers are used to trim along walkways, driveways, streets, and paths. They are used to create a well-defined and tidy perimeter. Here’s a look at how a cordless lawn edger can be used to spruce up your walkway borders.


Trenchers cut deep furrows in the earth. These may be used to make way for buried cables, pipes, irrigation systems, or electric dog fences.

Do you need a cordless lawn edger?

Lawn edgers can be used to give your look a tidy, manicured look. If you’re looking to improve the look of your lawn or garden, they are a failsafe way to get a professionally landscaped look for a low cost and very little effort.

If you’re torn between getting a corded, cordless, or manual edger, it’s worth noting that the cordless variety is easier to maneuver and less physically taxing.

The benefit of using a manual lawn edger is it’s cheaper and low-maintenance because of fewer moving parts. I’ve written a post where you can find some of the best and cheap manual lawn edgers so check it out.

Most landscapers consider edgers and string trimmers to be vital lawn maintenance assets. In fact, they’re just as important as a lawnmower. Cutting your grass without edging is like giving yourself a haircut without trimming the ends.

How to choose the best cordless lawn edger

Cutting Diameter and Depth

One style of edger utilizes a rotating trimming string to cut grass and weeds. Edgers that utilize string typically have a wide cutting diameter. Their cutting capacity typically ranges between 12 and 14 inches.

While traditional string trimmers require users to manually bump spent string, most of the newer models feature automatic feed features. Automatic feeds release a new section of string from a hidden spool. Replacement string spools can be purchased when the original one runs out.

Traditional edgers utilize metal blades to create well-defined borders. Blades may be flat, scooped, or pointed. The more dynamic the blade is the better it aerates the earth. Nevertheless, flat, rectangular blades still do an excellent job of cleaning up the edges around rudimentary walkways and other landscaping features.

Power Source

Consumers have a choice between electric and gas-powered lawn edgers. Gas lawn edgers are usually quite large and durable. They are used by professional landscapers or homeowners with large properties. Many hardware stores rent these out for a fee.

Electric lawn edgers may be corded or cordless. Corded lawn edgers are best suited for small yards with minimal obstacles. Keep in mind that corded edgers require a compatible extension cord. The length of the extension cord you use determines the range of the edger. Corded lawn edgers are usually a bit more powerful and resilient than the cordless variety.

Cordless edgers are extremely maneuverable. They rely on long-lasting, rechargeable lithium-ion batteries. Homeowners can enjoy the freedom of meandering around gardens and yard elements without having to worry about tangling or snagging an extension cord.

Shaft and Handles

It’s important that your edger has a shaft that’s long enough for you to edge without bending your knees or back. Telescopic shafts have adjustable heights that can be tailored to accommodate a wide range of users.

When it comes to handles, you should be able to grip both the top and middle of the shaft. As such, most manufacturers incorporate a pistol grip at the top and D-shaped handle on the top of the shaft.

Dual handles give you better stability, control, and comfort. This is especially important when you are performing precision edging. After all, the slightest sway can interrupt your border.


Cordless lawn edgers rely on wheels to guide them along a borderline. We recommend that you opt for a model with dual wheels.

These will give you more stability during edging tasks. It’s also important to choose a model with grippy all-terrain wheels that won’t slip on damp turf.


Cordless lawn edgers are simple and straightforward. We prefer models with protective shields. Without this add-on, these machines have the potential to toss lawn debris into the air.

Shields provide a protective barrier between your edger and any plants that may fall within its margins.

We also prefer edgers that can double as other yard tools, such as string trimmers and trenchers. Most homeowners have limited storage and spending budgets. As such, bundling similar landscaping tools into one base is an obvious solution.

If you do intend to invest in more than one tool, it’s important to find a cordless model with an interchangeable battery.

Precautions when using a cordless lawn edger

It’s important to take care and use caution when using power tools of any sort. We recommend that you abide by the following safety precautions when using your cordless lawn edger:

Wear Protective Gear and Clothing

Edgers and string-trimmers are powerful tools that can send debris spinning into the air. Always wear protective clothing, closed-toe shoes, gloves, and goggles when utilizing outdoor power tools.

Remove Obstacles

Maybe the dog left his bone along a footpath or the children abandoned a roller skate by the oak tree. These small obstacles can cause severe injuries if they come in contact with the blade of an edger. Always take the time to walk along the borders of your yard and remove any potential hazards before powering up your edger.

Clear the Area of Bystanders

Do your edging when pets and people are not around. Bystanders run the risk of coming in contact with airborne debris. Operators are at risk of colliding with people and pets.

Avoid Potentially Harmful Plants

Poison ivy and other potentially hazardous plants often grow around the perimeters of properties. Be sure to take care when trimming plants. The oils of some plants can cause major health problems.

How to use a cordless lawn edger

A cordless lawn edger can give your lawn a clean, manicured look with very little effort. Follow the instructions below to create clean, defined borders around your driveway, walkways, hedges, and more.

1. Tackle Major Landscaping Elements

Use your cordless lawn edger to create a small margin along the edges of your driveway, footpaths, and patios. Power lawn edgers work great when navigating along straight lines or 90-degree angles.

You may need to pull out a manual edger to tidy up the area around rounded edges. Remember, your edger is responsible for the heavy lifting. Just guide it along the border in a smooth, uninterrupted motion in order to achieve a clean, uniform border.

2. Walk the Walk

Hold your cordless edger at waist height. Outstretch your arms to push it forward. Walk slowly to ensure that you provide thorough coverage from start to finish.

If you are edging along a driveway or footpath, use it as your guide. This will remind you to keep the edge as tight as possible.

3. Use a String Trimmer

Once you’ve created defined edges along your property, use a string trimmer to cut the grass where your mower can’t reach.

Many cordless lawn edgers double as string trimmers. These handy add-ons make it easy clean around hedges and trees.

The Greenworks 18-Inch 10 Amp Corded String Trimmer is the best corded electric string trimmer you can use. It saves you time and effort while being easy on the pocket.

Maintaining your cordless lawn edger

It’s fairly easy to keep a cordless lawn edger in good running condition. However, there are a few small maintenance tasks you can do to extend the life of your tool while boosting its overall performance.

Keep a set or two of replacement blades and/or string-trimmer lines on hand. Follow the manufacturer’s instructions when replacing these elements. Take care to clean the head, removing any grass and debris. Scrape along the inside of your edger’s shield if it has one.

You’ll also want to take care to clean off your edger’s head after each edging session. While these tools are designed to withstand plenty of abuse, they don’t fare well when left to sit with moisture and dirt. Dry your edger and store it in a well-ventilated area.

If your edger has a rechargeable battery, do your best to charge it before putting it into storage. Most manufacturers recommend that lithium-ion batteries be charged to approximately 40% and stored in a cool (around 60 degrees Fahrenheit) dry area.
