Gas Mowers Require You to Pull-Start Them, Add Oil, and Sometimes Pray. Here Are Four That Don't.
Spring buying season is now. Gas mower owners know the ritual: fresh gas, fresh plug, choke, pull, fail, pull, fail, give up. Cordless electric lawn mowers start with a button, run quieter than a conversation, and require no oil changes, spark plug replacements, or carburetor cleanings. These four were chosen because buyers in climates from Georgia to Wisconsin confirm they handle real-world grass — not just perfect spring lawns.

EGO Power+ 56V 21-Inch
4.6★ · 2,134 reviews
56V ARC lithium battery, 21-inch steel deck, 6 cutting heights, 60-minute run time per charge. The mower that ended the gas vs. electric debate for most homeowners. Starts with one button, never needs oil changes, runs quieter than a conversation. 2,134 buyers confirm it handles thick, overgrown grass that stymied cheaper cordless mowers.
Greenworks 40V 20-Inch
4.2★ · 3,847 reviews
40V battery, 20-inch cutting deck, single-lever 5-position height adjustment. The cordless mower with the most verified reviews in this category. 3,847 buyers at 4.2 stars confirm it cuts clean on flat to moderate yards. Lighter than the EGO, easier to maneuver around obstacles. The right choice if you have a smaller yard and don't want to spend EGO money.
Ryobi 40V 21-Inch
4.3★ · 1,512 reviews
40V battery, 21-inch deck, brushless motor, cross-cut dual blade for finer clippings. If you already own Ryobi 40V tools, this is a no-brainer — same battery platform as your other Ryobi tools. The cross-cut blade produces mulch-quality clippings versus a single straight-cut blade. Works on slopes better than the Greenworks due to the wider deck and brushless motor.
Black+Decker 20V 10-Inch
4.1★ · 3,267 reviews
20V battery, 10-inch cutting deck, 6.6 lb total weight. Not a full-yard mower — this is for small patches, edging work, steep banks, and spaces too tight for a full-size mower. 3,267 buyers confirm it excels at the jobs a big mower can't reach. Folds flat for storage in a standard cabinet. The answer to 'I just need something for the front strip and the back corners.'
Which Cordless Mower Should You Buy?
Frequently Asked Questions
Depends on voltage and yard conditions. The EGO 56V runs up to 60 minutes per charge in normal conditions — enough for most yards under 1/3 acre. The Greenworks 40V and Ryobi 40V run 35–45 minutes under normal conditions. In thick or wet grass, run time drops 20–30%. Buyers with larger yards buy an extra battery and swap mid-mow.
Yes — if you buy the right voltage. The 20V Black+Decker is not designed for thick grass. The 40V Greenworks and Ryobi handle normal to moderately thick grass. The 56V EGO is confirmed by buyers to handle thick and overgrown lawns that cause cheaper mowers to bog down. Buy the voltage that matches your grass density.
Better than expected, but with limits. The Ryobi 40V brushless motor handles moderate slopes better than the Greenworks. The EGO 56V has the most torque for steeper terrain. Self-propelled cordless mowers exist (EGO makes them) for steep yards — none of the models on this page are self-propelled. For steep hills, you want a higher-voltage self-propelled model.
