Best Cordless String Trimmer and Edger Combos (2026)

The conversion on this model is what you notice first. The head converts from a string trimmer to an edger in seconds, and tilts 90 degrees, so the same tool handles sloped terrain, edges along paths and awkward corners under shrubs. A push-button Command Feed system adds instant line without bumping.

The design is simple. A single pivot on the shaft does the conversion, with no wheels to attach and no separate parts to lose, which is why it gets used. It is a 12 inch swath on a 20V motor, so it suits lawn edges and light weeds.

The weak point is power on thick growth, and runtime on a larger lawn. A single battery will handle a small to medium yard, but you should buy a spare for anything bigger. Clean the pivot after each use, because grit makes the head stiff over time. When you edge, hold the head so the line runs just above the paving, since pressing it down chews line and strains the motor. Because the battery is shared with other Worx tools, adding a spare is cheap, and the spare doubles as the pack for a future hedge trimmer.

Greenworks fits a brushless motor and a 12 inch dual-line head to a convertible trimmer-edger, and adds an adjustable-height shaft, which is a comfort feature that the simpler convertibles lack. A tool that fits your height reduces the stooping that makes edging a chore.

Brushless power means longer runtime on the 3.0Ah pack than a brushed 20V tool gets on a similar battery, and the motor holds speed better in damp grass. The kit also includes a brushless 515 CFM blower, which makes it a better deal than the trimmer alone if you need both.

The trimmer line is thin at 0.065 inch, so the tool is for lawn edges and ordinary weeds. If you want a heavy-duty trimmer, look to the 60V models. For most suburban lawns, it is the best pairing of motor and battery in this guide. The adjustable shaft is easy to overlook in a spec list, yet it is what lets two people of different heights share one tool without back strain. Set the height so the head sits flat when your arms hang naturally.

The third mode is the point. A removable wheeled deck turns the trimmer into a small mower, which suits small yards, slopes and corners that a standard walk-behind mower struggles to reach. An automatic feed spool keeps the line running without bumping, and two batteries and a charger are in the box.

Mowing with a trimmer head is a compromise. A 12 inch cut is narrow, and the deck is sized for small areas, so it is a tool for a handkerchief lawn or a bank, not a full-size yard. But as a way of avoiding buying a second machine, it is a clever one.

Two batteries mean you can rotate, which makes the deck mode practical. Clean the deck after use so wet clippings do not clog it, and store the batteries indoors. If you have a steep bank, it is the model that deals with it. Mow across the slope rather than up and down, which keeps the wheels from sliding and the deck from digging in. Raise the deck for the first cut of the season, then lower it as the grass settles.

This kit puts a convertible 40V trimmer-edger beside a sweeper. The LST140 has a high-torque POWER DRIVE transmission and an automatic feed spool, and the LSW40 sweeper moves air at up to 130 mph, which is enough to clear light debris from paving.

The 40V platform gives more energy and more torque at the string than the 20V tools in this guide, which matters when the head meets thicker growth while edging. One battery drives both tools, which is a convenient arrangement and a limitation: a long edging session can leave the sweeper with little charge.

It is the choice for someone who wants a stronger convertible and a clean-up tool in one box. Keep the spool housing clear of grass, check the sweeper intake for clogs and store the battery indoors. Because the two tools share a pack, charge it fully before starting and edge first, since the edger is the hungrier tool. If the sweeper falters, swap in a spare pack rather than forcing it on a nearly flat one.

The LCC221 is the lightest and smallest convertible here. A 10 inch swath, an adjustable-height handle with a soft grip and an automatic feed spool make it easy to handle, and it converts from trimmer to edger for border work.

The small head is a benefit in tight beds, where a 12 inch swath would hit plants, and a handicap on open lawn, where it covers ground slowly. A sweeper in the kit completes the job on paths and patios.

It makes sense for a small garden where the aim is a neat finish, not speed. Wipe the head after use, check the line length and store the battery indoors. Of the six, it is the easiest to put away. Its short shaft hangs on a hook in a garage or cupboard without taking floor space, which matters in a small house. Choose it if you value tidiness and control over raw speed.

The WG928 uses the same pivot-head idea as the WG163 and adds a 360 CFM leaf blower, so it is the better buy if you want a trimmer-edger and a clean-up tool from one maker. The listing describes a two-tool lawn care combo with a 12 inch trimmer that converts to an edger by pivoting the head, which makes lawn borders easier to keep tidy.

Command Feed is the feature that makes edging bearable. Edging runs the line vertically against hard edges, which wears it fast, and a push-button feed gives fresh line without stopping to bump the head. The trade is that a 20V system with two tools on one battery has to share that energy, so the trimmer gets less runtime than it would alone.

The blower is a light-duty tool for clippings and dry leaves, not wet piles. Plan the order of work so the trimmer uses the full battery and the blower finishes the job after a short recharge. Wipe the pivot, clear the blower intake and store both packs indoors. Compared with the WG163 alone, it costs more but removes the need for a broom. If you already own a blower, buy the WG163 instead and keep the difference. Owners with no blower will find the kit the cheaper way to get one.
