The best cordless lawn trimmer and edger combos for US homeowners are the Husqvarna 110iL FLXi (best overall), the Worx GT 3.0 (best budget), and the DeWalt 60V 17-inch (best for tough jobs), with battery power now replacing gas for most yards.
One machine that trims along fences then edges a clean sidewalk line is the holy grail of lawn care. You don’t want two separate tools, and you definitely don’t want gas fumes. Battery-powered trimmer/edger combos have reached the point where they outwork gas models for most US lawns—so which one actually converts cleanly and holds up season after season? The answer depends on your yard size, your budget, and whether you want a wheeled edger or a head-rotation setup.
What Makes a Trimmer and Edger Combo Worth Buying?
A true combo trimmer lets you switch between string-trimming and metal-blade edging without buying a second machine. The two main conversion systems are wheeled edgers (the Worx GT 3.0 locks your trimmer into a wheeled cart) and head-rotation systems (the Husqvarna 110iL FLXi rotates and locks the head 90 degrees). Both work well, but wheeled edgers give you more control over cutting depth while head-rotation models are faster to switch between jobs.
These models passed real-world testing from Popular Mechanics and Wirecutter, and each one actually converts from trimmer to edger without add-on kits or creative rigging.
Husqvarna 110iL FLXi — Best Overall
The Husqvarna 110iL FLXi uses a 40V X-Force battery and a clever FLXi edger conversion: you rotate the head 90 degrees, lock it, and the trimmer becomes an edger with a metal blade. It cuts a 13-inch path and handles thick grass without bogging down. At roughly $450–480 it is a premium investment, but the build quality and 40V ecosystem make it the most reliable long-term pick. If you are ready to buy a dedicated edger instead, our tested cordless edger roundup for small-to-medium lawns covers standalone models that may suit your needs.
Worx GT 3.0 (WG303.1) — Best Budget
The Worx GT 3.0 runs on the 20V PowerShare platform and costs roughly $130 for the trimmer. Its wheeled edger attachment clips on solidly and adjusts cutting depth from 1/4 to 1/2 inch. It is the best value pick for sub-0.5 acre lots, but the 20V system struggles with heavy overgrowth—keep it to routine edge maintenance, not clearing new ground.
DeWalt 60V Cordless (DCT410S1) — Best for Tough Jobs
DeWalt’s 60V FlexVolt trimmer cuts a 17-inch swath and spins fast enough to chew through thick brush. The edger conversion uses a dedicated metal blade attachment. At roughly $450–500 it matches the Husqvarna in price, but the wider cutting path and 60V power make it the right choice for larger lawns or tougher terrain. Expect 45+ minutes of runtime on a 9Ah battery.
Ego ST1511T — Best User Friendly
The Ego ST1511T runs on the 56V Power+ platform and has an AutoIQ line-feed system that feeds string automatically. Its edger conversion rotates the head like the Husqvarna, but the mechanism feels smoother and requires no tools. At roughly $350 it is a strong midrange option that trades raw power for ease of use.
RYOBI 40V Expand-It — Best Attachment System
The RYOBI 40V Expand-It accepts a separate edger attachment, making it a modular system rather than a dedicated combo. The trimmer body costs roughly $200 with a 4.0Ah battery, and the edger attachment adds about $60. The system is flexible—you can also add a blower or cultivator—but the edger conversion is not as seamless as the Husqvarna or Worx systems. Note that the 18V RYOBI line is not compatible and is widely panned on lawn forums.
How the Top Models Stack Up
The table below covers the models that actually convert to edgers, with specs from Popular Mechanics and manufacturer documentation.
| Model | Voltage | Cutting Width | Edger System |
|---|---|---|---|
| Husqvarna 110iL FLXi | 40V | 13″ | Rotating head + metal blade |
| Worx GT 3.0 | 20V | 12″ | Wheeled cart conversion |
| DeWalt 60V | 60V | 17″ | Dedicated metal blade |
| Ego ST1511T | 56V | 15″ | Tool-free head rotation |
| RYOBI 40V Expand-It | 40V | 14″ (with head) | Separate edger attachment |
How to Convert a Trimmer to an Edger in Six Steps
The process is the same across most conversion-capable models, although the specific locking mechanism varies. Always check your owner’s manual for torque specs on the blade nut.
- Disconnect the battery and engage the safety trigger lock before touching the head.
- Loosen the shaft collar or unlock the head-rotation lever (Husqvarna FLXi uses a twist-and-lock collar; Worx uses a quick-release lever).
- Remove the nylon string head and install the metal edger blade (typically 12-inch diameter). On wheeled edgers like the Worx GT 3.0, slide the trimmer into the cart until it clicks.
- Secure the blade by tightening the shaft collar or the blade nut. The Husqvarna FLXi system clicks audibly when locked; the Worx uses a nut and washer setup.
- Set the cutting depth by adjusting the edger wheel height—aim for 1/4 to 1/2 inch for most US sidewalks and driveways.
- Test at low speed before working at full throttle to confirm the blade is stable and aligned.
If the blade wobbles or the head won’t lock, recheck the shaft collar tightness and ensure you used the correct OEM blade for your model.
Common Mistakes That Ruin the Edging Job
Even a good trimmer combo produces bad results if you cut too deep or use the wrong battery. Set the wheel no deeper than 1/2 inch—anything deeper hits roots, cracks concrete, and burns through battery capacity. Speaking of batteries, edging draws sustained power, so a 2.0Ah battery on a 40V or 60V trimmer will die in under 10 minutes. Use at least a 4.0Ah pack for a typical small-to-medium lawn. And if you are pushing a 20V Worx through thick overgrowth instead of routine maintenance, the motor can burn out; that is where a 60V model earns its keep.
Battery Ecosystem and Compatibility Guide
Choosing a trimmer means committing to its battery platform—buy one brand and you stay with it for future tools. Here is what each system covers:
| Brand | Voltage | Battery Platform Name | Other Tools on Same Platform |
|---|---|---|---|
| Husqvarna | 40V | X-Force | Chainsaws, blowers, hedge trimmers |
| Worx | 20V | PowerShare | Over 100 tools (drills, saws, vacuums) |
| DeWalt | 60V | FlexVolt | Circular saws, mowers, blowers (60V and 120V) |
| Ego Power+ | 56V | Power+ | Mowers, blowers, snowblowers, chainsaws |
| RYOBI 40V | 40V | 40V Expand-It | Expand-It attachments, chainsaws, blowers |
Safety Gear and Installation Warnings
Edging throws heavy soil and small stones at high speed. Wear ANSI Z87.1-rated safety glasses and long pants—not shorts. Keep the blade away from rocks and exposed roots; impact can shatter the blade or cause violent kickback. Never run the trimmer near water with a battery, and if you edge wet grass, use a battery cover to keep moisture out of the ports.
Final Verdict: Which One Fits Your Yard?
If you have a medium lawn (0.5–1.5 acres) and want one machine that trims and edges cleanly, the Husqvarna 110iL FLXi is the buy. It converts faster than any other model and the 40V X-Force platform is proven. If your budget is tight and your lawn is under 0.5 acres, the Worx GT 3.0 delivers solid edge work for about a third of the price—just stay within its power limits. For thick grass, hills, or larger lots, the DeWalt 60V justifies its cost with raw power and a 17-inch cutting width that finishes jobs faster. The Ego ST1511T is the best pick for someone who hates fiddling with adjustments; the tool-free rotation and auto-line feed make it the lowest-hassle option in the group.
FAQs
Can any cordless trimmer be converted to an edger?
No. Only models specifically designed with a removable head, a shaft collar, or a wheeled-edger dock can convert. The models listed above—Husqvarna 110iL, Worx GT 3.0, DeWalt 60V, Ego ST1511T, and RYOBI 40V Expand-It—are the most reliable converters on the US market.
How deep should I set the edger wheel?
Set the wheel so the blade cuts 1/4 to 1/2 inch into the soil. Deeper cuts hit tree roots and concrete curbs, dulling the blade quickly and wasting battery power. For routine maintenance, a quarter inch is enough to create a clean line.
Do I need a larger battery for edging versus trimming?
Yes. Edging requires sustained motor torque and drains batteries faster than string trimming. A 2.0Ah pack may last only 8–10 minutes on a 40V edging job, while a 4.0Ah or larger pack handles a full lawn edge in one pass. Match the battery to the job.
Is a wheeled edger better than a head-rotation edger?
Wheeled edgers (like the Worx GT 3.0) give you precise depth control and a steady guide, making them better for beginners or long straight edges. Head-rotation edgers (like the Husqvarna 110iL) are faster to switch between trimming and edging mid-job, which suits experienced users tackling complex yards.
Can I use a 20V trimmer for thick overgrowth?
Not reliably. A 20V system like the Worx GT 3.0 handles grass and light weeds along established edges, but thick overgrowth, brush, or tall weeds will stall the motor or cause overheating. For that work, step up to a 40V or 60V model with a 4.0Ah-or-larger battery.
