Best 40V Cordless Lawn Edgers (2026)

This Greenworks set is a 12 inch string trimmer paired with a 390 CFM blower, not a dedicated edger with a blade. Both tools run on the 40 volt battery system, and a 2.0Ah battery with charger comes in the box. The listing says the battery charges in about 60 minutes.

The trimmer uses a .065 inch line with auto-feed and is meant to cut through weeds up to about an inch thick along fences and garden borders. The blower is rated at 110 MPH and 390 CFM, enough to clear wet leaves and clippings off concrete. The whole kit is described as an 8 pound balanced design, which keeps it manageable for edges and patio corners.

Compared with the Greenworks 8 inch edger, this combo does not cut a vertical trench in the turf. It trims along the edge with line instead. It does offer more flexibility, since one battery fits tools across the Greenworks 40V range. It suits a homeowner who wants a light, all-purpose pair and does not insist on a crisp spade-cut edge. Keep spare line on hand, and recharge the battery after each session.

Greenworks offers this bladed edger with an 8 inch blade and a curb wheel that helps you track along a sidewalk or driveway edge. It is sold as a bare tool, so battery and charger are not included. If you already own Greenworks 40V packs, that works in your favor.

The brushless motor produces more torque than a brushed motor and runs quieter and longer. Depth adjustment lets you control how far the blade cuts into the soil. The maker calls it virtually maintenance free, with no gas, oil or spark plugs to look after.

Against the WORX 20V edger, it uses the higher voltage platform that matches this guide's 40V focus, and its wider blade removes more material in one pass. Compared with the BLACK+DECKER string trimmer and edger, it gives a cleaner trench, though it cannot also trim grass. Because there is no battery in the box, add the cost of one before comparing totals. The lightweight, ergonomic design suits people who tire quickly with heavier tools. Wear eye protection, since an edger blade can throw dirt and small stones, and check the area for hidden sprinkler lines.

WORX makes this cordless edger around a streamlined 7 inch blade, and it runs on a 20 volt battery rather than the 40 volt class named in this guide. An edge guide and a blade indicator show where the cut will land, so you can follow a sidewalk or flower bed edge accurately. The tool weighs only 7 pounds without the battery, with dual wheels that help it roll along.

The listing claims up to 2800 feet of edging on a single charge, a generous figure that will depend on soil and grass. You can combine WORX 20V batteries, and the brand says the pack system extends to its 40V and 80V tools through adapters. That is helpful if you already own other WORX equipment.

Beside the Greenworks 8 inch, this edger is lighter and cheaper to run but has a smaller blade and a lower voltage. Against the corded WORX, it frees you from an extension cord. It suits an older gardener who wants a light, easy-to-maneuver tool for modest edges. Charge the battery before a big job, and keep the blade clear of gravel and roots that could dull or chip it.

This WORX edger is a corded unit with a 12 amp motor that spins a 7.5 inch blade at 4700 revolutions per minute. It is not a cordless 40V tool, so it sits slightly outside the premise of this guide. The listing mentions a built-in 1 foot power cord, which means you will need an extension cord to reach most edges.

Cutting depth can be set to 1, 1-1/4 or 1-1/2 inches depending on how deep a trench you want. A cutting line guide helps you stay straight along a path or bed. The shaft length adjusts, so people of different heights can find a comfortable position.

Compared with the cordless WORX, it never runs out of charge and spins faster, but you must manage the cord. Against the Greenworks 8 inch, it offers a similar blade size with no battery to buy. It suits a homeowner with short, straight runs near an outdoor outlet. Use a heavy outdoor extension cord and keep it behind you as you work. Wear eye protection and sturdy shoes, because the blade can throw soil, and unplug the tool before clearing a jam or changing depth.

BLACK+DECKER's 40V MAX tool is a 13 inch string trimmer that converts to edging, rather than a bladed edger. It runs on a 40 volt lithium ion battery with a state-of-charge indicator, so you know when to stop and recharge. A fast charger is included and restores a full battery in roughly two hours or less.

A selector lets you choose maximum power for thick weeds or maximum runtime for long stretches of light trimming. The POWERDRIVE transmission sends more of the motor's energy to the cutting line. An automatic feed spool advances line as needed, so you do not tap the head on the ground.

Compared with the Greenworks combo, it is a single dedicated tool with a wider cutting swath. Against the Greenworks 8 inch edger, it cannot cut a vertical trench in the soil, but it trims grass the edger cannot touch. It is the premium pick in this lineup for homeowners who want flexibility over a crisp edge. Check the spool before each session, and wear eye protection against flying debris. Switch to runtime mode for long driveways to avoid stopping early, and rotate the tool to edge by following the manual instructions.
