Best String Trimmer with Edger (2026): 4 Picks

Side-by-side specs

21 October 2026

What the listings tell you

We read the four listings end to end, and the honest split is two true edgers and two blower combos. The EGO and BLACK+DECKER answer the keyword; the Greenworks pair answers the adjacent question of trim-and-blow. The rankings reflect that: edging function first, then power, then the rest. Voltage runs 20V to 56V. True edging functions appear twice: the EGO’s edger attachment and the BLACK+DECKER’s wheeled edger mode. The Greenworks combos pair trimmers with blowers, not edgers. Line feed is automatic on all four. Batteries run 2.0 to 4.0 Ah.

Where each combo fits

A note on the listings: the Greenworks combos are trimmer-plus-blower kits, not trimmer-plus-edger; they are included per the job’s product list but they do not edge. The rankings favor the two that do: the EGO’s dedicated edger blade and the BLACK+DECKER’s wheeled edger mode. Warranty terms are stated on all four.

Think of these four as answers to different yards. The EGO MHC1603 is the edger answer: a dedicated 8 in edger blade on 56V. The BLACK+DECKER is the convertible answer: trimmer to wheeled edger in one motion. The Greenworks 13 in is the combo answer: trimmer plus blower for the whole yard. The Greenworks 12 in is the blower answer: 390 CFM for heavy debris.

Buying guide: the best string trimmer with edger

True edger vs rotated head

Two of these edge for real: the EGO’s 8 in edger blade attachment and the BLACK+DECKER’s wheeled edger mode. The Greenworks combos have no edging function; their second tool is a blower. A rotated trimmer head edges adequately, but a blade or a wheeled guide cuts the cleaner line. If edging is the job, buy the tool that names it.

Voltage

Voltage runs 20V to 56V here. The EGO’s 56V out-powers the field; the 40V Greenworks pair sits in the middle; the 20V BLACK+DECKER is the lightest duty. More volts means more torque in thick weeds, at the cost of weight. For weekly edging on a suburban lot, 20V suffices; for overgrown edges, 40V and up.

Line feed

All four feed automatically: AFS on the BLACK+DECKER, auto feed on the Greenworks pair, POWERLOAD on the EGO. POWERLOAD is the standout: push a button and the head winds the line itself. The others advance line as you work without stopping. For a beginner, any auto feed beats bump feed.

Battery

Batteries run 2.0 to 4.0 Ah. The EGO’s 4.0 Ah runs up to 45 minutes trimming and 75 minutes edging; the Greenworks 2.0 Ah charges in 60 minutes. The BLACK+DECKER’s 2.5 Ah claims 66% more runtime than standard models. Bigger batteries mean fewer swaps; the EGO’s runtime figures are the only stated ones here.

Warranty

All four state warranty terms: lifetime on the EGO’s carbon fiber shafts, 3 years on the Greenworks 12 in’s head, 3 years limited on the Greenworks 13 in, and 2 years limited on the BLACK+DECKER. A lifetime shaft warranty on a tool you swing for years is the standout term here.

Runtime

Stated runtimes appear once: the EGO runs up to 45 minutes on the trimmer and up to 75 minutes on the edger at low with the 4.0 Ah battery. The BLACK+DECKER claims 66% more runtime than standard models without naming minutes. The Greenworks pair names no runtimes. For edging a typical lot, the EGO’s 75-minute edger figure is the only hard number; the rest run on battery size as the proxy.

Weight and handling

None of the four listings states a product weight. The practical read: the 56V EGO system with two attachments is the heaviest; the 20V BLACK+DECKER is the lightest class. The shoulder strap in the EGO box is the handling aid for longer sessions. When the listing is silent on weight, voltage is the rough proxy: more volts, more heft.

Carbon fiber shafts

The EGO’s attachments use carbon fiber shafts, backed by a lifetime warranty. Carbon fiber is light and stiff; on a tool you swing for an hour, that matters more than it sounds. The other three use unstated shaft materials. The lifetime warranty is the maker’s bet that the shafts outlast the tool; take the bet.

The 66% runtime claim

The BLACK+DECKER claims 66% more runtime than standard models without naming the standard. Treat it as directional: the 2.5 Ah battery is bigger than the usual 2.0 Ah, so more runtime follows. The EGO’s 45 and 75 minute figures are the only stated runtimes here; everything else is battery math.

The 320W charger

The EGO includes a 320W charger, the only charger wattage stated here. Higher wattage means faster charging; the Greenworks 2.0 Ah charges in 60 minutes on an unstated charger. For a two-battery workflow, the charger speed matters as much as the battery size: the EGO’s 320W keeps the spare ready.

Matching It to Your Property

• Sidewalk and driveway edges: the EGO’s 8 in edger blade or the BLACK+DECKER’s wheeled edger mode cut the line.
• Fences, garden borders and obstacles: any of the four feeds line automatically, so you keep moving between posts and beds.
• Leaf and debris cleanup: the Greenworks 12 in lists a 390 CFM blower and the 13 in a 350 CFM blower.
• Battery and storage: all four run on a battery, with no fuel to store; the EGO runs on 56V, the Greenworks pair on 40V and the BLACK+DECKER on 20V MAX.

The Acre Score explained

Each combo is scored on performance, build, value, safety and warranty. All four listings state a warranty term: the EGO’s lifetime shaft warranty, the Greenworks 12 in’s 3-year head warranty, the Greenworks 13 in’s 3-year limited warranty and the BLACK+DECKER’s 2-year limited warranty. None names a safety certification.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

FAQ: mowing large lots

How do I switch the EGO attachments?

The EGO’s multi-head system swaps the trimmer and edger attachments on the PH1420 power head. The listing does not detail the swap mechanism; multi-head systems typically use a coupler and a pin. The BLACK+DECKER converts without detaching anything, which is faster mid-job.

Trimmer or edger first?

Trim first, edge second: the trimmer clears the overgrowth, the edger cuts the clean line. The EGO and BLACK+DECKER do both; the Greenworks combos trim and blow.

Is the EGO worth it for edging?

If edging matters, yes: it is the only one with a dedicated edger blade attachment. The others edge by conversion or not at all.

What does POWERLOAD do?

It winds the trimmer line automatically at the push of a button. No disassembly, no manual winding. The EGO is the only one here with it.

20V enough for edging?

For maintained edges, yes. The BLACK+DECKER’s 20V with PowerDrive transmission handles weekly edging; overgrown or woody edges want 40V or 56V.

Do the Greenworks combos edge?

No. They pair a trimmer with a blower. For edging, the EGO’s attachment or the BLACK+DECKER’s wheeled mode are the picks.
