Greenworks 40V 21 in. Brushless Self-Propelled Mower
Greenworks packs a brushless motor and Smart Pace self-propulsion into an affordable 40V platform. The mower includes two 4.0Ah batteries and a charger, providing around 60 minutes of combined runtime. The 21-inch deck handles 2-in-1 mulching and rear bagging with seven height positions from 1.5 to 3.75 inches.
EGO POWER+ LM2150SP Select Cut XP
The LM2150SP is EGO's most powerful push mower, producing up to 8.3 ft-lbs of torque. With a 10.0Ah battery (sold separately) it can run up to 75 minutes, enough for a full acre on a single charge. The Select Cut XP system lets you choose between high-lift, standard, and mulching blades depending on the season and grass type.
Greenworks 40V 16 in. Push Mower
For compact lawns up to a quarter acre, the lightweight 16-inch Greenworks is a practical option. It weighs significantly less than 21-inch models and is easier to maneuver around tight corners and garden beds. The 4.0Ah battery provides around 45 minutes of run time, and the unit is compatible with the Greenworks 40V tool ecosystem.
SnapFresh 40V 16 in. Cordless Mower
The SnapFresh uses two 20V batteries in series to deliver 40V total power with a brushless motor for efficient energy use. It includes two 4.0Ah batteries and a fast charger, offering enough runtime for small to medium yards. Six cutting height positions and a 2-in-1 mulch and bag function add versatility at a competitive price point.
How to Choose a Cordless Lawn Mower
The most important factors are yard size and terrain. For yards under a quarter acre on flat ground, a 16-inch push mower is sufficient and lighter to handle. For half-acre yards with slopes, a self-propelled 21-inch mower with a high-capacity battery is worth the investment. Check whether the battery system is compatible with other tools you own, since sharing batteries across a brand's ecosystem reduces costs.
Deck size, cutting height range, and whether the mower mulches, bags, or side-discharges are secondary but useful considerations.
FAQ
How long do cordless lawn mower batteries last per charge?
Runtime varies by model and conditions. A 56V 7.5Ah battery like EGO's provides around 45 to 60 minutes on a typical lawn. Thick, wet grass, slopes, and higher speed settings all reduce runtime. Most manufacturers sell additional batteries so you can swap mid-mow on larger properties.
Are battery lawn mowers as powerful as gas mowers?
High-end 56V models from EGO match or exceed the torque of typical residential gas mowers and handle thick grass without bogging down. Entry-level 40V models are suitable for regular maintenance cuts on thin to medium grass, but may struggle with very tall or dense growth.
How often should I sharpen the blade?
A general guideline is once per season or after approximately 20 to 25 hours of use. A dull blade tears grass rather than cutting it cleanly, which stresses the lawn and creates a ragged appearance. Most blades can be sharpened at home with a file or bench grinder, or replaced inexpensively.
Can I leave a battery in the mower between uses?
For short storage periods between mows, leaving the battery in the mower is fine. For seasonal storage (over winter), manufacturers generally recommend removing the battery and storing it at room temperature with a partial charge to preserve cell health.
