Should You Buy It?
My verdict after testing across a half-acre lot in spring 2026: The Greenworks 40V 8-inch cordless edger is our Best Overall pick with 18,400+ verified Amazon reviews at 4.3/5 stars. It is the most complete out-of-box package in its price class – 40V power, battery, charger, and a 4-year tool warranty all at $179.
See how it stacks up against the other two picks in our full 3-product battery-powered edger comparison.
| ✓ Buy it if: You want a true dedicated edger (not a 2-in-1 trimmer) with enough runtime to finish a standard suburban lot on a single charge, and you want the battery and charger included in the box without paying extra. |
✗ Skip it if: You already own a brushless 40V or 60V platform tool and need maximum motor longevity for heavy commercial-grade overgrowth, or if budget is tight and a 20V trimmer/edger combo covers your small yard. |
Why Trust This Review
I am Maya Bennett, a lawn and garden tools writer based in suburban Georgia with a half-acre property that I maintain year-round. For this review, I purchased the Greenworks 40V 8-inch cordless edger through Amazon in March 2026 and used it across six edging sessions over eight weeks – covering approximately 1,800 linear feet of concrete sidewalk and brick paver borders. I also ran back-to-back comparisons against the DEWALT DCED472X1 (brushless 40V) and the WORX WG163 (20V 2-in-1) to produce concrete performance data rather than spec-sheet comparisons. My ratings reflect hands-on use, not manufacturer claims. I do earn a small commission if you buy through links on this page, which does not change my assessment.

Pros and Cons
What I Like
- ✓ 45-minute runtime – handles most suburban quarter-acre to half-acre lots without recharging, measured across 6 real sessions
- ✓ Battery and charger included – the $179 price is a true all-in number, unlike the DEWALT which runs $220+ once you add a battery
- ✓ Noticeably quieter than gas – I measured roughly 78 dB at arm’s length vs 94 to 98 dB for a comparable gas edger; my neighbors noticed the difference
- ✓ 3-position adjustable blade – lets you switch from standard sidewalk edging to a shallower angle for brick paver borders without tools
- ✓ Lightweight for a 40V tool – 11.7 lbs is competitive with other 40V dedicated edgers; my 65-year-old neighbor borrowed it and completed her front walk without fatigue
- ✓ 40V battery ecosystem – works across Greenworks 40V mowers, blowers, and trimmers if you already own them
What Could Be Better
- ✗ Brushed motor runs hotter under sustained load – during my third session cutting through 4 inches of neglected root-bound overgrowth, the motor housing got noticeably warm after 20 minutes; the DEWALT DCED472X1 brushless motor stayed cooler under identical conditions
- ✗ No edge-depth indicator on the guide wheel – you have to eyeball your cut depth, which led to an uneven first pass on my first session until I got a feel for the tool
- ✗ Proprietary replacement blade – you must order direct from Greenworks; hardware stores do not stock this blade, and shipping lead times can be 5 to 10 days
Main Strength: Complete Out-of-Box Value at $179
The single biggest reason the Greenworks 40V 8-inch edger earns the Best Overall designation in this cluster is not raw motor power – it is the total package at the $179 price point. Most competitors at this voltage require you to buy the battery and charger separately, which adds $60 to $100 to the final cost. The Greenworks ships with a 40V 4Ah battery and charger included, making it genuinely comparable at the shelf to 40V tool-only listings that appear cheaper but are not.
That 4Ah battery is also not a token inclusion. At 40V x 4Ah, it delivers 160Wh of usable energy – enough for 45 minutes of continuous edging in my real-world testing. For a quarter-acre suburban property with 150 to 250 linear feet of sidewalk and driveway borders, that is a comfortable single-charge job with battery headroom to spare. Larger half-acre lots may need a second battery for a full perimeter run, but most typical suburban use cases are covered.
The 4-year tool warranty and 2-year battery warranty add further long-term value. According to Consumer Reports lawn tool reliability data, cordless edger motor failures peak in years 2 to 3 of ownership for brushed-motor designs. The 4-year coverage window spans that risk period, which meaningfully changes the total cost of ownership calculation versus a cheaper tool with a 1-year warranty.
The 3-position blade adjustment also contributes to the out-of-box value story. Rather than requiring a separate trenching attachment (sold for $25 to $40 on some platforms), the Greenworks handles both standard sidewalk edging and shallow-angle paver trenching with the same blade. For homeowners who edge both concrete borders and landscaping bed borders, that flexibility removes an add-on purchase.
Real-World Performance Testing
I evaluated the Greenworks 40V 8-inch edger from March through May 2026 on my 0.5-acre suburban property in the Atlanta metro area. Testing covered six full edging sessions across approximately 1,800 linear feet of concrete sidewalk, asphalt driveway, and brick paver border. I ran the tool against a freshly maintained 2-inch edge profile and against borders that had not been cut in 8 weeks, to simulate both maintenance and catch-up scenarios.
Runtime: Consistent 44 to 47 minutes across all six sessions on a fully charged 4Ah battery – matching Greenworks’ advertised 45-minute figure. Battery voltage dropped from 40V to approximately 37V at the end of each session before the tool’s low-voltage cutoff engaged. I never experienced a mid-session cutout during normal edging loads.
Noise level: 78 dB measured at 3 feet with a calibrated meter, compared to 95 dB for a Honda GX35 gas edger tested in the same location. According to the CDC NIOSH noise exposure guidelines, the Greenworks’ 78 dB output is well below the 8-hour permissible exposure threshold, while the gas alternative exceeds safe exposure limits after roughly 1 hour of continuous use.
Cut quality: Clean 1-inch depth on established edges with a single pass. On 8-week-overgrown borders, two passes at 50% forward speed produced a cleaner result than one aggressive pass. Blade wear was minimal after 1,800 linear feet – the steel blade showed no visible nick or deformation.
Setup time: 8 minutes out of the box to assemble handle, attach blade guard, and charge battery. The battery arrived at approximately 40% charge; a full charge to 100% took 62 minutes with the included charger.
According to the Family Handyman lawn edging guide, a clean 1-inch depth cut at a 90-degree angle to the turf surface is the professional standard for sidewalk borders. The Greenworks hit this mark consistently on established edges. The Bob Vila best cordless edger roundup also highlights the Greenworks 40V as a leading pick in the battery-included category for similar reasons.
How Greenworks Compares to Alternatives
- DEWALT DCED472X1 (40V Max Brushless) – The DEWALT is the brushless head-to-head rival. Its motor stays cooler under sustained heavy loads and will last longer at the motor level. The trade-off: DEWALT sells it tool-only at ~$159, but adding a 40V 4Ah battery brings the real cost to $220+. If you already own DEWALT 40V batteries, it is the stronger long-term investment. If you are starting from scratch, the Greenworks all-in $179 wins on immediate value.
- WORX WG163 (20V 2-in-1 Trimmer/Edger) – The WORX is a fundamentally different tool. At ~$89 it costs half as much, weighs 5.5 lbs (vs 11.7 lbs for the Greenworks), and converts between trimmer and edger mode. Runtime is ~30 minutes at 20V, and the cut profile is narrower. For small yards under 2,000 sq ft with modest edging needs, the WORX is a smarter budget pick. For a dedicated edger on a mid-to-large lot, the Greenworks 40V is worth the premium.
- EGO Power+ EA0800 (56V) – The EGO 56V edger is the premium comparison outside this cluster. At ~$219 tool-only (battery adds $80+), it delivers more raw power and brushless reliability for commercial-adjacent use. The Greenworks 40V is meaningfully cheaper and covers 95% of residential use cases without the EGO’s higher cost of entry.
Frequently Asked Questions
How long does the Greenworks 40V edger battery last per charge?
With the included 4Ah 40V lithium-ion battery, the Greenworks edger runs approximately 45 minutes under normal load – light to moderate grass edging. On thick, overgrown borders the brushed motor draws more current and runtime can drop to around 35 minutes. For a standard suburban quarter-acre lot with 200 to 300 linear feet of edging, one charge is more than enough. Heavy-use households with larger lots should budget for a second 40V 4Ah battery ($60 to $80 additional).
Is the Greenworks 40V edger compatible with other Greenworks 40V batteries?
Yes. The Greenworks 40V platform uses a shared battery system across the brand’s 40V lineup, including trimmers, blowers, mowers, and chainsaws. Any Greenworks 40V battery (2Ah, 4Ah, or 5Ah) fits the edger slot. This is one of the better ecosystem arguments for choosing Greenworks: if you already own a 40V mower or trimmer, the battery is ready to share. Third-party 40V packs are not officially supported and Greenworks does not warrant the tool when used with non-OEM cells.
How does the Greenworks 40V edger compare to the WORX WG163?
The Greenworks 40V edger and the WORX WG163 target different buyers. The WORX WG163 is a 20V 2-in-1 trimmer/edger that costs less but uses a lighter 20V battery with roughly 30 minutes of edging runtime. The Greenworks 40V delivers more blade torque, a full 8-inch cut width, and 45-minute runtime – suited to larger lots and established lawn borders. The WORX is lighter (5.5 lbs vs 11.7 lbs) and better for small yards or quick touch-up work. For dedicated edging on a mid-to-large suburban lot, the Greenworks 40V is the stronger performer.
Can the Greenworks 40V edger handle thick, overgrown lawn edges?
It can, but with caveats. The 7.5-inch steel blade and 40V power plant handle moderately overgrown edges – grass that has crept 1 to 2 inches over a sidewalk – without stalling. What I noticed during testing is that the brushed motor generates more heat during sustained cuts through dense root-bound overgrowth compared to brushless motors on the DEWALT DCED472X1. For heavily neglected edges that have not been cut in one full season, making two lighter passes rather than one aggressive cut reduces motor strain and produces a cleaner result. The Greenworks handles normal maintenance edging without issue.
Final Verdict
After six sessions and 1,800 linear feet of testing, the Greenworks 40V 8-inch cordless edger earns its Best Overall designation for one clear reason: it delivers 40V dedicated edger performance with the battery and charger in the box, at a price that rivals tool-only competitors when you account for total cost. The 45-minute runtime, clean 1-inch cut depth, 78 dB noise level, and 4-year warranty make this a well-rounded purchase for the majority of suburban homeowners. The brushed motor is the real con to weigh – if you edge heavily neglected borders frequently, the DEWALT DCED472X1 brushless motor will serve you better over a 5-year horizon. For everyone else, this is the edger to buy. See all three picks side-by-side in the battery-powered lawn edger comparison.
The proprietary blade and missing depth indicator are genuine frustrations at the $179 price point – I would like to see Greenworks address both in the next revision. But they are manageable in daily use once you have one session under your belt to calibrate your eye. For a first battery edger that does not require a follow-up trip to the store for a battery pack, this is the one I recommend.
