Are Electric Mowers as Good as Gas? | Honest Verdict

For most homeowners with average suburban lawns, electric mowers are now as good as gas mowers in practical use, and they often win on noise, convenience, and maintenance.

The short answer depends on your yard. Electric mowers have closed the gap dramatically in recent years, matching gas on runtime for typical 1/4-acre lots while sidestepping the fuel, oil, and pull-cord hassle. But gas still holds a clear edge when the grass is thick and wet, the lot is steep, or you need to mow for longer than a single battery charge allows. Here’s how to decide which one belongs in your shed.

How They Compare on What Matters Most

Consumer Reports testing shows gas walk-behind mowers still beat electric models on raw cutting and bagging performance—but not by a wide margin for most people. Electric mowers pull ahead on noise level, maneuverability, the complete absence of exhaust smell, and the near-zero maintenance routine (no oil changes, no spark plugs, no stale gas to drain). Bob Vila notes that cordless electric mowers commonly deliver 30 to 60 minutes of runtime, while gas mowers run about 45 to 60 minutes per tank. For the average suburban yard under 1/3 acre, that means one charge or one tank finishes the job—so the practical difference is minimal.

Cutting Power: When Gas Still Wins

If your lawn routinely gets tall, wet, or dense, gas mowers cut through it with less slowdown. Electric motors deliver strong torque, but the battery voltage and amp-hours determine how well they handle a full grass catcher or a thick patch of damp Bermuda. The gate here is simple: if you regularly bag wet grass or mow overgrowth, gas is the steadier choice.

Total Cost: Electric Saves Over Time

Gas mowers are often cheaper at purchase, running $200–$400 for a solid model compared to $300–$600 for a capable electric. The math flips over five years, according to Consumer Reports—electric owners skip gas, oil, air filters, spark plugs, and carburetor cleanings entirely. The catch is battery replacement: a new 40V or 56V battery costs $100–$200 when the original fades, typically after three to five years. If the mower was bought as a kit with two batteries, you get more cycles before needing a purchase.

If you are ready to make the switch, our tested picks for the best electric mowers cover the models that actually deliver on runtime and torque without the fluff.

Common Mistakes Buyers Make

Overestimating battery range. The advertised runtime assumes dry, short grass on flat ground. Wet or overgrown conditions can cut that number by a third. Measure your actual yard and buy a mower with at least 50 percent more rated runtime than you think you need. Ignoring the battery platform. A 40V battery from one brand will not fit another brand’s mower—and often will not work across that same brand’s older or newer models. Comparing price bare. The mower’s price tag alone never tells the full story—always check whether batteries and charger are included or sold separately. A $249 “tool only” mower becomes a $449 purchase when you add two batteries and a charger.

Which Should You Buy?

Choose electric if your lawn fits on a single battery charge (most cordless mowers handle a 1/4-acre yard), you value quiet Saturday mornings, and you would rather avoid the seasonal ritual of draining gas and changing oil. Choose gas if your lawn exceeds 1/3 acre, the terrain is steep, the grass routinely gets wet and tall, or you want the reassurance of refueling in seconds instead of waiting an hour for a recharge. Either way, matching the mower to your actual conditions matters more than the fuel label.
