Edgers separate the yards that look pro-maintained from the ones that just look mowed. A crisp edge between the lawn and the driveway, between the grass and the garden bed, along the sidewalk — that clean line is what tips a yard from "cut" to "finished." But a dedicated lawn edger is a real tool, not a string trimmer flipped sideways, and choosing between gas and electric affects how often you actually use it.
Modern 80V cordless edgers deliver cutting depth and blade speed that match residential gas edgers, without the fuel, fumes, or startup ritual. But the answer still isn't "electric wins across the board." This guide walks through the honest tradeoffs of gas vs electric edgers in 2026, plus which one fits typical Canadian homeowner use.
The Fundamental Comparison
- Gas edgers burn 2-cycle fuel to spin a vertical blade. Sustained cutting power, unlimited runtime with fuel, but heavier, noisier, and maintenance-heavy.
- Electric (battery) edgers use lithium-ion batteries. No fuel, no oil, minimal maintenance, quieter — but constrained by battery capacity per session.
For residential edging — driveways, sidewalks, garden bed borders, front walkway edging — 80V cordless has fully closed the performance gap.
Cutting Performance
| Typical Residential Gas Edger | Greenworks 80V 8" Edger | |
|---|---|---|
| Engine/motor | 25–29cc gas 2-cycle | 80V brushless |
| Blade size | 7"–9" | 8" |
| Cutting depth | Up to 2" | Up to 2" |
| Blade speed | 3,000–4,000 RPM | ~4,000 RPM |
| Cutting through established sod | Excellent | Excellent — matches gas |
| Cutting through overgrown edges | Excellent | Excellent |
| Sustained edging | Unlimited (with fuel) | Limited by battery |
For residential edging — weekly maintenance edging, seasonal restoration of overgrown edges, garden bed border establishment — 80V cordless matches typical residential gas edgers in real-world cutting performance. The old "electric edgers can't cut real edges" complaint applied to 20V–40V cordless. 80V closed the gap.
Cutting Depth — What Matters
Edger cutting depth determines what jobs the tool can actually handle:
| Depth | Best Fit |
|---|---|
| Under 1" | Light maintenance edging only |
| 1–1.5" | Residential standard — weekly edging maintenance |
| 1.5–2" | Serious residential — overgrown edge restoration, new bed cutting |
| 2"+ | Commercial territory |
The Greenworks 80V 8" edger delivers up to 2" cutting depth — top residential tier. Handles both weekly maintenance edging and the deeper cuts needed to restore edges that have been neglected for a season or two.
Runtime — The Structural Difference
| Job | Gas Edger | 80V Single Battery | 80V Larger Battery |
|---|---|---|---|
| Weekly driveway edging | Fine | Fine (single charge) | Overkill |
| Full-property maintenance edging | Fine | Fine (single charge) | Fine |
| Seasonal edge restoration | Fine | May need swap | Fine |
| New garden bed cutting | Fine | Multiple swaps | 1 swap |
| Commercial daily edging | Preferred | Impractical | Impractical |
For most Canadian homeowners with typical residential edging needs, 80V cordless handles the property in one battery. Overgrown restoration work may need battery swaps or a larger battery.
Weight and Ergonomics
Edgers are used with the wheels on the ground and a controlled walking pace — weight matters, but not as dramatically as with overhead tools:
- Gas edger: Typically 15–20 lbs. Wheeled base carries the weight, but the top-heavy engine placement affects control during turns and adjustments.
- Electric edger: Typically 10–15 lbs. Better weight distribution because the battery counterweights the cutting head.
The bigger practical difference is starting — gas edgers require a pull-cord start, often multiple attempts on cold mornings. Electric edgers start immediately with a trigger squeeze.
Cost of Ownership
| Cost Category | Gas Edger | 80V Electric Edger |
|---|---|---|
| Purchase (tool + battery kit for electric) | $250–$450 | $200–$400 (tool only or kit) |
| Fuel + 2-cycle oil (10 years, weekly use) | ~$200 | ~$10 electricity |
| Spark plugs / air filters | ~$50 | $0 |
| Blade replacement (both) | ~$60 | ~$60 (same) |
| Winter fuel stabilizer | ~$30 | $0 |
| Carburetor cleaning / repairs | ~$100 | $0 |
| Battery replacement (year 6–8) | N/A | ~$150 |
| 10-year total | $690–$890 | $420–$620 |
Electric wins meaningfully on lifetime cost — the fuel-and-maintenance savings compound significantly over a decade. If you already own 80V batteries, the tool-only edger purchase makes this gap even wider.
Maintenance
- Gas edger annual maintenance: Fuel mixing, fuel stabilizer for winter, spark plug replacement, air filter cleaning, carburetor cleaning after untreated fuel, blade replacement or sharpening.
- Electric edger annual maintenance: Blade replacement or sharpening. That's it.
Canadian winter storage kills gas 2-cycle engines through ethanol fuel absorption in cold garages. Spring startup often reveals winter fuel damage. Electric edgers don't care about winter storage — remove the battery, put it on a shelf, done.
Noise
- Gas edger: 95–105 dB. Requires hearing protection. Loud enough to disrupt neighbours.
- 80V cordless edger: 75–85 dB. Doesn't require hearing protection for typical residential use.
Edging happens along property lines — driveways bordering neighbours, sidewalks in front of neighbouring houses. Quieter cutting reduces friction meaningfully. Some Canadian municipalities restrict gas equipment during early morning and evening hours; electric typically falls below these thresholds.
Cold-Weather Starting
Same story as every gas outdoor tool. Below 5°C, pull-cord frustration begins. Spring edging — the first time you use the tool each year — often reveals winter fuel damage on gas edgers.
Electric edgers start immediately regardless of temperature.
The Best 80V Electric Edger for the Switch
For Canadian homeowners making the switch from gas — weekly maintenance edging, garden bed borders, seasonal restoration — the Greenworks 80V 8" Brushless Edger (Tool Only) is built for this transition:
| Spec | Greenworks 80V 8" Brushless Edger |
|---|---|
| Voltage | 80V brushless |
| Blade size | 8" dedicated edger blade |

Adjustable cutting angle. 0° straight cuts along walkways; 15° or 30° bevel cuts for decorative garden bed edges.
Adjustable wheel guide. Sets consistent cutting depth so edges look uniform along their entire length.
Tool-only pricing. If you already own 80V batteries from other Greenworks tools, this saves $100–$150 vs. a full kit.
4-year warranty. Longer than most gas edgers.
Full 80V POWERALL ecosystem. Same battery works across 75+ Greenworks 80V tools.
Making the Switch — What to Expect
Practical adjustments:
- Consider battery size based on property. 2.0Ah for small yards, 4.0Ah for larger properties.
- Store batteries indoors during winter. Canadian cold reduces battery life if stored in unheated spaces.
- Sharpen or replace the blade annually. Same as gas — sharp blades cut cleaner, dull blades tear grass and strain the motor.
- Sell your gas edger. Working gas edgers hold reasonable used value.
Edger Technique
Three tips for cleaner edges:
- Walk at a steady slow pace. Rushing produces uneven edges. The tool cuts a specific depth at a specific speed; forcing it faster than that just makes messy cuts.
- Follow existing edges the first time. If you're maintaining an established edge, follow the existing line. If you're establishing new edges, use string or a garden hose as a guide.
- Edge before you mow, not after. Mowing after edging cleans up the debris; the reverse leaves cuttings on the freshly-edged line.
FAQ
Does 80V really match gas edger cutting power?
For residential use, yes. 80V brushless motors deliver blade speed and torque comparable to typical 25–29cc gas edgers. Real-world cutting through established sod is comparable.
Can I use a string trimmer as an edger instead?
You can rotate a string trimmer head vertical for occasional edging, but the results won't match a dedicated edger. String line frays at edges; dedicated edger blades produce crisp, deep, straight cuts. For weekly edging maintenance, a dedicated edger is worth the investment.
How long does the battery last per charge?
On a 2.0Ah battery: 30–45 minutes of continuous edging. On a 4.0Ah battery: 60–90 minutes. Enough for typical residential edging sessions.
Is 8" blade enough for residential use?
Yes. 8" is the residential standard. Larger blades exist on commercial edgers but add weight without meaningful residential benefit.
Can this cut through overgrown edges that haven't been edged in years?
Yes, though it takes more time. Set to full 2" depth and work in short sections. Overgrown edges may require two passes to fully restore.
Is the tool-only version enough for a first-time buyer?
Only if you already own 80V batteries. If this is your first Greenworks 80V purchase, buy a kit or add a battery+charger separately.
