DeWalt Edgers and Trimmers: Genuine Tools and 20V-Compatible Picks

Best for
20V owners wanting trimmer, edger, mini mower

Best for
Large yards and heavy overgrowth

The DEWALT 60V Cordless String Trimmer, model DCST972X1, is the flagship of this list and the only kit that includes a battery and charger. It runs on a 60V MAX FLEXVOLT battery, which the listing says also works in DeWalt 20V MAX tools, so it can anchor a battery collection rather than just join one.

A brushless motor drives the head at up to 8000 rpm, with a variable trigger and hi/lo speed switch to balance power and runtime. The swath adjusts between 15 and 17 inches using 0.080 inch dual line, and the listing says it also accepts DeWalt 0.095 inch line. A quick-load spool speeds re-spooling, and universal attachment capability lets you add other DeWalt outdoor attachments to the same power head. It weighs 15 pounds, the heaviest here.

This suits owners of larger properties with thick overgrowth who want genuine DeWalt build and support. Readers with small lawns and an existing 20V battery may find a lighter compatible tool easier to handle. For more on this style, see our guide to the DeWalt battery powered weed eater lineup.

• Brushless motor, up to 8000 rpm
• 15 or 17 inch adjustable swath
• 60V MAX FLEXVOLT battery and charger included
• Attachment capable

Best for
Crisp sidewalk and bed edges

The Brusless Lawn Edger Compatible with Dewalt batteries is made by worksky, not DeWalt. It is the only dedicated blade edger in this list, and it runs on DeWalt 20V MAX batteries you supply; no battery or charger is included.

A brushless 800W motor spins a 9-inch steel blade at 3500 rpm, and three depth settings run from 1.3 to 1.75 inches for anything from sidewalk touch-ups to garden trenches. A 1.77-inch front wheel and 4-inch rear wheel help it track straight, and a plough blade widens the groove in one pass. It weighs 7.2 pounds, the tube comes apart for storage, and a dual-action start guards against accidental activation. The listing claims a 3-year warranty, though that line refers to a leaf collector and sweeper, so confirm the terms with the seller. The listed product dimensions of 1 by 1 by 1 inches are clearly a placeholder.

Pick this if clean, deep edges matter more than trimming. It does not trim grass or weeds along fences, so pair it with a string trimmer.

• 9-inch steel blade, 3500 rpm
• Three depth settings
• Dual wheels and plough blade

The Cordless String Trimmer Compatible with Dewalt batteries comes from SHOHO, not DeWalt, and is sold as a bare tool without battery or charger. Its hook is versatility: the listing describes a 3-in-1 design that converts between a precision trimmer, an upright wheeled edger and a mini lawn mower.

A copper-wound motor reaches a no-load speed of up to 9000 rpm, with a 12-inch working diameter. The upgraded spool system is meant to stop line from tangling, and automatic line feed releases about 0.4 inches of line at each start if the spool has enough. An auxiliary handle adjusts through 180 degrees and the head tilts from 0 to 90 degrees. The listing does not specify weight or warranty.

This fits a 20V battery owner with a small to mid-size yard who wants to trim, edge and tidy tight patches with one tool. For heavy overgrowth, the genuine 60V trimmer has more capacity. Our roundup of DeWalt weed wacker with wheels options covers similar wheeled edging setups.

Best for
Shaping hedges and shrubs

The DEWALT 20V MAX 22″ Cordless Hedge trimmer, model DCHT821B, is a genuine DeWalt tool sold bare, with no battery or charger. It is not a grass trimmer or edger; it is for shaping hedges and shrubs, and it belongs here because many yard days end at the bushes.

Laser-cut 22-inch hooked tooth blades handle branches up to 3/4 inch thick, and the listing claims up to 78 minutes of runtime, though it does not say which battery produced that figure. A friction clutch protects the transmission when the blade hits an obstacle, and DeWalt says the design is 39% more compact to reduce arm fatigue. It weighs 9.7 pounds.

This suits 20V MAX owners with hedges to maintain. For grass and edges, pair it with one of the string trimmers above.

• 22-inch hooked tooth blades
• Cuts up to 3/4 inch branches
• Friction clutch protection

Best for
Light trimming with a spare 20V battery

The Weed Wacker Cordless Compatible with DEWALT batteries is made by AXORIX, not DeWalt, and ships without battery or charger. It is a 2-in-1 string trimmer and edger: you adjust the head and rotate the shaft to switch modes, and an auxiliary wheel helps when edging.

The listing claims up to 12,000 rpm, the highest speed figure here, and a 12-inch cutting width, though the spec table lists 11 inches. Single-sided automatic line feed keeps line coming, and six pre-wound spools are included. At 4.5 pounds with a 180-degree adjustable handle and 90-degree rotating head, it is easy on arms, and a dual-switch system prevents accidental starts.

This suits homeowners who want a light trimmer that can edge without buying a separate edger. It lacks the mini mower mode of the SHOHO and Houselife tools.

Best for
Lightest 3-in-1 for small lawns

The Cordless Weed Wacker Compatible with DEWALT batteries is a Houselife tool, not a DeWalt product, and is sold tool only. Like the SHOHO, it converts between a string trimmer, a wheeled edger and a mini lawn mower, and it adds a flower guard to protect plants.

Its copper wire motor runs at up to 8500 rpm with a 12-inch cutting diameter. Line feed works two ways: automatic release of 0.4 inches at each start plus a manual option. It weighs just 4.2 pounds, the lightest here, with a 180-degree auxiliary handle, a 90-degree tilting head, a dual safety lock and a quick-install guard. The listing states a one-year warranty.

Choose this for small lawns and users who value low weight above speed. For a similar tool with a higher listed speed, the SHOHO is the alternative.
