Best 40V Cordless Lawn Edgers (2026)

The Greenworks is a true blade edger: an 8 inch steel blade spins vertically and slices a trench along the edge, while a curb wheel rides the concrete to keep the line straight. That is the part that makes it more precise than a string trimmer turned sideways, which tends to wander. A brushless motor adds torque and longer life.

Tool-free depth adjustment lets you set the cut depth without hunting for a wrench, and it handles uneven or sloped ground. It includes a 4.0Ah battery and charger, unlike the bare-tool version of the same edger, which excludes both. The warranty is four years on tool and battery, the longest in this guide.

Check blade wear each season, clear soil from the housing and store the battery indoors. It suits owners with long concrete edges.

The HART is a walk-behind edger with an 8.5 inch blade, slightly larger than the Greenworks 8 inch blade, and a brushless motor. It lists a 20 inch cutting swath, a wheel-spacing figure that describes its working footprint. A larger blade can cut a little deeper in one pass, which helps on edges that have crept over.

The listing is brief compared with the Greenworks, with no stated depth system or warranty, so verify those before buying. It includes a 4.0Ah battery, the same capacity as the Greenworks kit.

It uses the HART 40V battery platform, so check that the packs will serve other tools you own. Clear the housing, check the blade and store the battery indoors. It suits owners in the HART ecosystem.

This BLACK+DECKER is a trimmer that converts to an edger in seconds, with a telescoping pole, a PowerCommand dial that trades power for runtime and an automatic feed spool. The PowerDrive transmission is designed to send more motor power to the string, and the head spins up to 8500 rpm.

A string edge is fast and forgiving but not as crisp as a blade, because the string flails rather than slices. It is a good fit for light, regular edging on a lawn that is kept up. Against the Greenworks 13 inch trimmer, it adds a power dial and telescoping reach.

The included battery has a state-of-charge indicator and charges in two hours or less. The warranty is three years. Replace line as it wears, clean grass from the guard and store the battery inside.

The Greenworks combo tool has a seven-position pivoting head, which is its main advantage over a basic trimmer: you can set the head at the angle that suits trimming under a deck or edging along a walk. A telescoping shaft from 40 to 52 inches fits different heights, and it uses 0.065 inch auto-feed line.

It weighs a stated 7.8 pounds, a little more than the Wild Badger's 6.6. A steel edging guide helps keep a line. Like all string tools it cuts a softer edge than the dedicated blade edger.

A 3-year tool and 2-year battery warranty is solid, and the 40V battery fits other Greenworks tools. Replace line, clean the head and store the battery indoors. It suits users who want more head angles.

The Wild Badger is the lightest here at 6.6 pounds, a real advantage when you edge a long border. It spins at 6500 rpm, below the BLACK+DECKER's 8500, which means a gentler cut. The listing claims about 30 minutes of runtime and includes two packs of trimmer line.

It is a plain 2-in-1 with auto feed and a 13 inch path. A smaller maker means thinner support than the Greenworks or BLACK+DECKER, and the listing offers little detail on the head or warranty.

Line wears quickly at edging, so the spare packs are practical. Clean the guard and charge indoors. It suits cost-conscious owners.
