A wobbly trimmer head that won’t hold a straight line against a sidewalk is the difference between a manicured lawn and one that looks neglected. An eger trimmer combo solves this by packaging the two tools that define the finished edge of your property into a single battery platform, so you move from whipping tall grass to carving a crisp border without switching battery systems or hunting for a second charger.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. I’ve spent years analyzing battery-platform ecosystems, cutting-width specs, and real-world runtime claims across cordless outdoor power equipment to separate marketing from what actually holds up on a half-acre lot.
This guide breaks down the best options available right now, ranked by how well each kit balances motor torque, battery capacity, and head articulation for real trimming and edging work. Whether you are maintaining a postage-stamp city lot or managing an acre of turf, you need a best edger trimmer combo that matches the density of your grass and the length of your fence line.
How To Choose The Best Edger Trimmer Combo
Every combo kit forces a trade-off between line gauge, battery voltage, and head adjustability. The decision starts with whether you need a dedicated edger blade or whether converting the trimmer head 90 degrees is enough for your concrete borders.
Battery Voltage & Platform Lock-in
A 20V system keeps weight down and works for thin grass on a small lot, but 40V and 56V systems drive thicker .080″ to .095″ line without bogging. The voltage also determines which other tools you can add later — a 56V platform from a brand like EGO opens up chainsaws and mowers that share the same battery.
Cutting Width & String Gauge
Wider cutting swaths (12″ to 15″) reduce the number of passes along a fence line. Thicker string (.080″ or .095″) resists snapping against woody weeds but demands more torque from the motor. Narrower 10″ heads with .065″ line are fine for weekly maintenance on fescue or Bermuda.
Edger Function: Conversion vs. Dedicated Attachment
A convertible trimmer tilts its head and uses the same string to edge — this works for light cleanup but leaves a less defined groove. A dedicated edger attachment uses a steel blade or a stiff guide wheel to cut a clean 2″ to 3″ trench, which matters if you edge multiple times per season.
Automatic Line Feed vs. Bump Feed
Bump-feed heads require tapping the spool on the ground to advance string. Push-button or automatic-feed systems (like AFS or Command Feed) let you advance line without stopping your stride, which saves time on larger yards where you reload several times per session.

In‑Depth Reviews
1. EGO MHC1603 Multi-Head Combo Kit
This is the only kit in the roundup that gives you a proper edger attachment with an 8-inch steel blade and a depth-adjustable guide wheel rather than relying on a tilted trimmer head. The carbon fiber shafts reduce swing weight noticeably compared to aluminum, and the POWERLOAD string system on the 16-inch trimmer attachment lets you reload line by feeding it in and pressing a button — no disassembly required.
The 56V 4.0Ah battery delivers up to 45 minutes of runtime on the trimmer and up to 75 minutes on the edger at low speed, which is enough for an average suburban lot on a single charge. The two-speed digital trigger with lock-off lever gives you fine control over the 16-inch cutting swath, and the shoulder strap distributes the weight of the power head across your torso instead of hanging off your wrist.
Connecting the attachments to the power head requires aligning a locking collar, and some users find the mechanism stiff at first. The 48-inch shaft length can feel long for shorter operators when edging horizontally along a flower bed. But for anyone who edges more than once a month and wants a dedicated blade that cuts a true trench, this is the most capable edger trimmer combo on the list.
What works
- Dedicated steel-blade edger attachment cuts a clean 3-inch trench
- Carbon fiber shafts are noticeably lighter than metal alternatives
- POWERLOAD string reload saves minutes per spool change
What doesn’t
- Attachment collar can be difficult to lock on the first few uses
- Long shaft requires leaning for low-angle edging
2. EGO POWER+ ST6703LB
This combo pairs a 15-inch string trimmer with a leaf blower that pushes 670 CFM at 180 MPH, which is more airflow than most gas backpack blowers produce. The 0.095-inch dual-line spiral twist string handles thick weeds and overgrown grass without frequent breakage, and the POWERLOAD system is the fastest reload method available today — feed the line in, push the button, and the head winds it automatically.
The brushless motor on the trimmer delivers consistent torque through the cutting swath, so the head doesn’t bog when you hit a patch of crabgrass. The telescoping aluminum shaft adjusts to fit different user heights, and the blower includes a tapered nozzle for concentrated force and a spread nozzle for wide sweeping. The 56V 4.0Ah battery provides about 30 minutes of trimming at full speed before it needs a swap.
The trimmer requires a manual pivot for edging — there is no dedicated edger attachment included. The battery pack weighs enough that the trimmer feels slightly head-heavy when fully extended. But if you need one tool to trim the yard and another to clear a driveway full of oak leaves in a single pass, this kit delivers more blowing force than any other combo at this price tier.
What works
- Blower output rivals gas backpack units at 670 CFM
- 0.095″ dual string lasts through tough weeds without snapping
- POWERLOAD string system is the fastest reload on the market
What doesn’t
- No dedicated edger blade attachment included
- Battery adds noticeable head weight during extended trimming
3. BLACK+DECKER 40V Max LCC340C
The jump from 20V to 40V gives this trimmer enough torque to spin a 13-inch head through thicker grass without slowing down, and the Power Drive transmission multiplies that torque further for clean cuts at the edges of driveways. The included blower pushes 130 MPH, which is sufficient for grass clippings on hard surfaces but not for wet leaves or heavy debris.
The trimmer head tilts 90 degrees convert into an edger, and the automatic feed system (AFS) advances line without bumping. The 40V battery includes a state-of-charge indicator, so you know exactly how much runtime remains before heading to the far side of the yard. At 11 pounds total kit weight, it is light enough for a single arm to carry both tools between storage and the work area.
The edging guide on this model is a thin metal bar that does not provide the stability of a proper wheeled guide, which means the cut depth varies with how much downward pressure you apply. The blower is single-speed, so you cannot dial back for delicate flower beds. But for someone moving up from a basic 20V trimmer who wants noticeably more cutting power without jumping to a 56V budget, this 40V kit hits a strong mid-range value point.
What works
- 40V motor with Power Drive transmission handles thick grass well
- Automatic line feed works without bumping the head
- State-of-charge indicator prevents unexpected battery death
What doesn’t
- Edging guide bar is flimsy compared to a wheeled guide
- Blower is single-speed and struggles with wet debris
4. WORX WG928 20V Combo
WORX bundles its GT trimmer with a turbine-style blower that churns 360 CFM at 75 MPH, which is a wide, fast-moving column of air ideal for clearing grass clippings off a patio or blowing dry leaves out of mulch beds. The trimmer converts to an edger by pivoting the head, and the Command Feed button lets you advance string instantly without stopping your stride.
The included 20V batteries are the lower-capacity packs, so runtime lands around 20 to 25 minutes of continuous trimming. Swapping the battery from the blower to the trimmer extends your session, but the slow charger means you will wait hours between full charges. The trimmer weighs only 5.3 pounds with the battery attached, making it one of the lightest kits here for overhead edging along retaining walls.
The .065-inch string that ships with the kit is thin and breaks more frequently when hitting woody stems. Upgrading to a thicker aftermarket line improves durability, but the spool capacity is small. Despite those limitations, the blower alone justifies the package for anyone who wants a high-volume sweep tool paired with a capable 12-inch trimmer for moderate weekly maintenance.
What works
- Turbine blower moves 360 CFM for wide-area sweeping
- Trimmer weighs only 5.3 lbs for fatigue-free overhead work
- Push-button Command Feed advances line without bumping
What doesn’t
- Included .065″ string breaks easily on thicker weeds
- Batteries charge slowly and provide limited runtime
5. WORX WG170 3-in-1
The WG170 is the only trimmer here that includes support wheels to turn the head into a mini lawn mower, which is useful for trimming over large flat areas of grass that a mower cannot reach, such as around a playset or under a low-hanging tree. The head rotates through six settings, and the handle has seven adjustment points, so the tool can be dialed in for a wide range of user heights and reach preferences.
The 12-inch cutting swath uses a bump-feed head with WORX’s Command Feed button as a backup, giving you both options for line advancement. The 20V motor spins at 7600 RPM, which provides enough speed for standard yard grass but will bog in heavy brush. The kit includes two batteries and a charger, plus three spare spools of line, so you can start trimming immediately.
The wheels are small and do not roll well over soft turf, and the mini-mower function leaves a less uniform cut than a dedicated mower. The batteries take roughly five hours to charge completely and provide about 22 minutes of runtime under load — enough for a small yard but tight for a quarter-acre lot. Still, no other combo at this price level offers three distinct cutting modes with that many adjustment options.
What works
- Support wheels enable mini-mower mode for flat open areas
- Seven handle positions and six head settings for custom fit
- Includes two batteries and three spare spools out of the box
What doesn’t
- Small wheels do not track well on soft or uneven ground
- Batteries require a slow 5-hour charge cycle
6. BLACK+DECKER 20V Max LCC222
This entry-level kit keeps the weight down to 4.5 pounds for the trimmer and 3.7 pounds for the blower, making it the lightest combo in the lineup and a strong choice for smaller users or anyone who needs to carry tools across a property. The 10-inch cutting width is narrow — you will make more passes along a fence than a 15-inch head — but the AFS auto-feed system keeps line advanced without tapping, and the trimmer head pivots for edging along sidewalks.
The two 1.5Ah batteries provide roughly 20 to 30 minutes of runtime each, which is enough for a standard city lot if you are not cutting heavy weeds. The batteries hold their charge for up to 18 months in storage, so the tools are ready after sitting in a garage all winter. The blower is quiet and adequate for sweeping dry grass clippings off a driveway, but it will not move wet leaves or gravel.
The charger is slow, taking several hours to fully recharge a depleted battery, so you need to plan your sessions around charge cycles. The trimmer line is thin and snaps more often on thicker growth. But for the price, you get a complete three-tool system (trimmer, edger, blower) that shares a common battery platform with other BLACK+DECKER 20V tools, making it a painless entry point for light yard maintenance.
What works
- Extremely lightweight at 4.5 lbs for fatigue-free operation
- AFS auto-feed advances string without bumping the head
- Batteries hold charge up to 18 months in storage
What doesn’t
- 10″ cutting width requires more passes along edges
- Blower is too weak for wet leaves or heavy debris
7. Houselife Dewalt-Compatible 3-in-1
This kit is a bare-tool bundle that runs on Dewalt 20V MAX batteries, making it a low-cost expansion for anyone who already owns Dewalt power tools and wants to add a trimmer, edger, hedge trimmer, and blower without buying into a new battery system. The 8500 RPM motor spins a 12-inch head with auto-line feed, and the head tilts 90 degrees for inline edging with a support wheel.
The bundle includes a 22-inch hedge trimmer with dual-action blades and a 5/8-inch cutting capacity, which is a useful addition if you have boxwoods, shrubs, or low-hanging branches to shape. The blower is optimized for dry debris on hard surfaces — it will clear a garage floor or patio quickly but lacks the volume for wet leaves on a lawn. The included flower guard snaps onto the trimmer head to protect plants and furniture from stray string.
The edger position uses a single small wheel that feels flimsy when applying downward pressure, and the trimmer consumes line quickly during heavy use — one spool may not finish a 30-foot edging pass on thick grass. Build quality does not match name-brand tools, and the warranty is only 30 days unless you register for a one-year extension. But for Dewalt ecosystem owners who need a trimmer and blower for occasional cleanup, this is the most affordable way to get a complete set without buying new batteries.
What works
- Runs on existing Dewalt 20V batteries, no new charger needed
- Includes hedge trimmer with 5/8″ cutting capacity
- 8500 RPM motor provides good string speed for standard grass
What doesn’t
- Edger wheel feels flimsy and does not provide stable guidance
- Trimmer line consumption is high, depleting spools quickly
Hardware & Specs Guide
String Gauge & Spool Capacity
A thicker string (.080″ to .095″) resists breaking against woody stems and stiffer grasses like Bahia or St. Augustine, but it demands a higher-torque motor. Thinner .065″ line is lighter and easier on the motor but snaps more often, requiring frequent stops to advance or reload. The spool capacity determines how many feet of line you can store — larger spools mean fewer trips back to the spool supply.
Brushless vs. Brushed Motors
Brushless motors deliver more torque per watt and run longer on a single charge because there are no brushes creating friction or consuming energy. They also last longer because there are no physical brushes to wear out over time. Every premium kit in this roundup uses a brushless motor; entry-level 20V kits often use brushed motors to keep the initial cost lower.
Cutting Swath Width
A 15-inch or 16-inch cutting swath covers roughly 50% more ground per pass than a 10-inch head, cutting trimming time significantly on larger properties. The trade-off is that a wider head requires a more powerful motor and heavier battery to maintain consistent line speed, which increases overall tool weight. Narrow 10-inch heads work well for precise edging and small flower beds.
Battery Chemistry & Voltage
20V lithium-ion packs are the most common and cheapest to replace, but they deliver the least torque and shortest runtime under load. 40V packs nearly double the available current, allowing thicker line and faster cutting through heavy grass. 56V ARC Lithium packs from EGO provide the highest torque density and can run accessories like mowers and chain saws from the same battery platform.
