Best Weed Eater Edger Combo for Lawn Care
As an Amazon Associate we earn from qualifying purchases.
A weed eater edger combo is one powered head that works as a string trimmer for weeds and grass and converts to a wheeled edger for clean lawn borders along walks, driveways and beds. Most combos use a shared motor and a detachable head, so you buy one tool instead of two. The six options below cover corded, 20V battery, 18V brushless, and gas-style listings. Each one is described only by what its listing states. Read the battery and charger lines closely, because several listings sell the tool bare or include only one battery.
Quick answer
- Choose battery or corded by where you work. The corded BLACK+DECKER listing needs an outlet and a cord run, while the 20V and 18V listings run on lithium-ion packs.
- Check what is in the box. The Bosch listing is a bare tool, so the battery and charger are sold separately. The Gisam and BLACK+DECKER 12-inch listings include two batteries.
- Pick a cutting width that fits your edges. The listings in this roundup state widths of 10, 12 and 16 inches.
- Look for an edger that converts without extra parts. The BLACK+DECKER and Gisam listings describe a head rotation or wheeled deck for edging.
What a weed eater edger combo does
A weed eater edger combo uses one drive unit with two working heads. In trimmer mode, a spinning nylon line cuts grass and weeds around fences, trees, posts and beds that a mower cannot reach. In edger mode, the head is turned or the attachment is swapped so that a wheel guides a cutting edge along a hard surface. The result is a straight, clean line where the lawn meets a path. A combo saves storage space and reduces the number of batteries you need, because the same pack runs both jobs.
The design has trade-offs. A combo is usually heavier than a single-purpose trimmer, and the edging head is a compromise: it cuts a clean line, but it does not replace a dedicated edger for long walks. Most listings in this group describe the edger as suited to small to medium lawns, so the best combo depends on how often you edge and how large the area is.
How to choose an edger combo
Start with power. Corded models, such as the BLACK+DECKER 12-inch listing with a 6.5 amp motor, avoid battery charging but limit where you can work. Battery models give you freedom to move around the yard. The BLACK+DECKER 20V listings use 1.5Ah packs, and the KIMO listing uses two 2.0Ah batteries. The Bosch listing uses an 18V brushless system, and the Gisam listing uses two 4.0Ah batteries. Battery capacity sets run time, so match it to the size of your yard.
Next, look at cutting width. A 10-inch width suits narrow strips and tight spaces. A 12-inch width covers more area in each pass. The Bosch listing describes a 16-inch cutting swath, which is the widest in this group. The BLACK+DECKER and KIMO listings describe 12-inch widths, and the BLACK+DECKER 20V listing describes a 10-inch cutting width.
Then check the edger. The edging conversion is the feature that makes a combo worth buying. The BLACK+DECKER corded listing says the trimmer head rotates to become a wheeled edger. The BLACK+DECKER 3-in-1 listing describes a wheeled edger, and the Bosch listing describes a dual-function grip that switches from trimming to edging. The Gisam listing describes a 3-in-1 setup that includes a lawn mower deck, a trimmer and an edger. Read how each listing handles the switch, because some require removing a guard or changing a deck.
Finally, check the included parts. Several listings include an auxiliary handle, a guard and an AF-100 spool. The KIMO listing includes four line spools, six blades and three nozzles for blowing, which broadens its use beyond edging.
Power source and battery notes
A corded model needs an outlet and a cord management plan. The BLACK+DECKER corded listing describes a cord retention system that helps prevent accidental disconnects. A battery model needs a charged pack before each job. The BLACK+DECKER 20V MAX listing lists a 1.5Ah pack, and the BLACK+DECKER 3-in-1 listing includes two LBXR2020 20V MAX lithium-ion batteries. The KIMO listing says a single battery covers a large area per charge and that the batteries can charge in one hour. Those figures come from the listings and should be checked against the battery label before you buy.
Keep batteries out of extreme heat and cold, and charge them in the charger supplied with the tool. Store the pack at room temperature, and do not leave a charger connected for long periods unless the manual says it is safe.
Roundup: six weed eater edger combos
Each block below uses the listing’s own facts. Where a listing does not state a fact, this roundup says so.
1. BLACK+DECKER corded 12-inch electric lawn mower, weed eater and edger 3-in-1 combo (model BESTA512CM)
This corded combo is a 12-inch 6.5 amp electric unit.

The listing includes a BESTA512 string trimmer, an MTD100 detachable mower deck, an AF-100 spool, an auxiliary handle and a guard, and it names a 2-year limited warranty. The listing gives a best-fit use for small lawns and compact spaces. The listing does not state the cord length, so check that before you choose an outlet location.

3. BLACK+DECKER 3-in-1 weed eater, lawn edger and cordless lawn mower combo (model MTC220)
This BLACK+DECKER combo turns from a 12-inch string trimmer into a push mower or an edger. The listing describes a removable wheeled deck, which makes the unit a small lawn mower for slopes and tight spaces. It includes two LBXR2020 20V MAX lithium-ion batteries, an MTD100 detachable mower deck, an AF-100 spool, an auxiliary handle, a guard and an LST220 string trimmer. The listing gives a 12-inch cutting width and states the unit weighs 9.9 pounds. It names PowerDrive technology to prevent bogging in dense grass, and a 2-year limited warranty. Choose this model when you want a mower option as well as a trimmer and edger in one package.
4. Bosch GRT18V-40N 18V brushless 16-inch cordless string trimmer and lawn edger combo (bare tool)
The Bosch listing is for a bare-tool 18V brushless string trimmer with a 16-inch cutting swath and an edging conversion. The listing states a maximum speed of 5,300 RPM. It describes a Bosch Anti-Tangle System that keeps the head moving through dense grass and weeds, a Pro-Tap spool with EasyWind for fast line advancement, and a toolless adjustable D-handle that switches between trimming and edging. The trimmer has a variable-speed trigger and a durable aluminum motor housing. The battery and charger are sold separately, and the listing says the tool works on the AMPShare 18V platform. The listing states a five-year limited warranty. This option suits a buyer who already owns Bosch 18V batteries and wants a wide cutting path for larger yards.
5. Gisam 18.9-inch cordless lawn mower, string trimmer and wheeled edger 3-in-1 combo
This Gisam listing is a 3-in-1 convertible unit: a cordless push mower with a detachable deck, a string trimmer and a wheeled edger. The listing states a brushless motor up to 15000 RPM and two 4.0Ah batteries in the box, so no separate battery purchase is needed. It describes three interchangeable blades: a string head for regular lawns, metal blades for heavier weeds, and an alloy saw blade for shrubs. The listing gives a 12-inch cutting width and three cutting height levels. The telescopic shaft adjusts between 20 and 80 degrees, which the listing presents as a way to reach corners and edges. The listing includes a note that the circular saw blade is not compatible with the lawn mower base, and that the base must be removed for that blade. Buyers who want a mower and an edger in one unit may find this listing useful.
6. KIMO weed eater and blower combo with 12-inch electric weed wacker and edger
The KIMO listing is a combo of a 12-inch electric weed wacker and edger with a 190 MPH leaf blower and vacuum function. The listing says both the trimmer and the blower use brushless motors, and that the trimmer spins at 20,000 RPM. It states a blower output of 260 CFM and 190 MPH. The kit includes two 20V 2.0Ah batteries and a 1-hour charging time, according to the listing. The trimmer has an auto line feed system and comes with four line spools, six blades and three nozzles for inflating and deflating items. The head adjusts to 90 degrees for edging. The listing says both machines can run at the same time. This option suits a buyer who wants trimming, edging and blowing from one battery pair, and who values extra spools and blades in the box.
Closer look: the BLACK+DECKER 3-in-1 combo
Of the six listings, the BLACK+DECKER 3-in-1 combo (model MTC220) covers the most jobs in one package. It has a 12-inch cutting width, two 20V MAX lithium-ion batteries, and a removable wheeled deck that the listing describes as a small push mower. The trimmer head works as a string trimmer for weeds and grass, and the same unit becomes an edger when you change its setup. The listing includes an auxiliary handle and a guard, and it names a 2-year limited warranty. Those items matter for everyday use, because the handle helps with control on longer jobs and the guard keeps debris away from your legs.
The unit weighs 9.9 pounds according to the listing, which is light enough for most people to carry around edges, but it is still a two-handed tool for long sessions. Keep your grip firm and your stance stable when you edge along a curb. The listing describes an adjustable pivoting handle and adjustable trimmer and deck heights, which help you match the setting to the grass.
Two close alternatives are the BLACK+DECKER 20V MAX combo (model LCC222) and the BLACK+DECKER corded 12-inch combo (model BESTA512CM). The 20V MAX combo is the choice if you want a sweeper in the kit and a lighter 10-inch trimmer, while the corded 12-inch model is the choice if you do not want to charge batteries. Compare the cutting widths and the battery count before you decide.
Keeping the edger line clean
Edging works best when the head and the line are in good shape. Replace worn line before it runs short, because short line bounces and leaves ragged edges. The listings in this group describe automatic feed systems, which advance line as needed. An automatic feed head still needs the right spool, so keep a spare spool or line on hand. Trim along one edge at a time, and keep the wheel on the hard surface so the cut stays straight.
Clean the head after each job. Remove grass and dirt from the spool housing and the guard, because clumps can slow the head and cause uneven cutting. Check the guard and the auxiliary handle for looseness before you start. A loose guard can shift during work and expose the cutting line.
Safety basics for trimmers and edgers
A string trimmer throws debris at high speed, so wear eye protection, long pants and closed shoes. Keep bystanders, pets and children at a safe distance. Use the guard on the trimmer head whenever the listing includes one. Turn the tool off or disconnect the battery before you change the head, the spool, or the blade. Check the cord for damage before each corded session, and keep the cord clear of the cutting path.
If you have a back, shoulder or hand condition that makes handling a tool hard, ask a doctor or physical therapist before you use a combo for long periods. If you are unsure how to set up or repair a battery or corded tool, ask a qualified electrician or the manufacturer.
Common mistakes to avoid
- Buying a combo without checking whether the battery and charger are included. The Bosch listing is a bare tool.
- Choosing a cutting width that is too wide for narrow edges, or too narrow for a large lawn.
- Assuming every edger conversion works the same way. Read how each listing handles the switch.
- Running a trimmer with worn line or with the guard missing.
- Ignoring the battery label. The 20V and 18V listings use different battery platforms, so check the platform before you buy a second pack.
FAQ
Is a weed eater edger combo worth it?
It is worth it when you want trimming and edging from one tool and one battery platform, and when your edges are short to medium length. A dedicated edger may suit very long walks better. Compare the edging head, the cutting width and the included parts before you decide.
Which combo includes batteries?
The BLACK+DECKER 20V MAX combo includes two batteries and a charger. The BLACK+DECKER 3-in-1 combo includes two LBXR2020 20V MAX batteries. The Gisam listing includes two 4.0Ah batteries. The KIMO listing includes two 20V 2.0Ah batteries. The Bosch listing is sold as a bare tool without a battery or charger.
What is the widest cutting width in this roundup?
The Bosch listing describes a 16-inch cutting swath, which is the widest stated figure in this group. The 12-inch listings from BLACK+DECKER, Gisam and KIMO are next, and the BLACK+DECKER 20V MAX listing describes a 10-inch cutting width.
Can a corded combo edge as well as a battery model?
The corded BLACK+DECKER 12-inch listing describes the same rotating-head edger conversion as the battery models. Edging quality depends more on the head, the line and your technique than on the power source. The main difference is mobility and the cord.
Do I need to remove a guard to edge?
It depends on the listing. Read the setup instructions for the specific model, because some edger conversions require moving the head or changing the attachment. Do not run a trimmer without its guard unless the manual allows it.
How often should I replace trimmer line?
The listings do not give a replacement interval. Replace line when it wears short, frays or breaks often. Keep a spare spool or line on hand, because the automatic feed systems in several listings depend on a correctly wound spool.
Bottom line
Choose the weed eater edger combo whose power source, cutting width and included batteries match the yard you have. For one tool that covers trimming, edging and mowing, the BLACK+DECKER 3-in-1 listing states the most jobs in one package. For a wider cut and a brushless platform you already own, the Bosch bare tool is the listing to compare. Confirm the battery and cord situation before you order, and read the edger setup in the listing so you know what you are buying.
