Best Cordless Lawn Mower Review
EGO 21-Inch 56-Volt Self-Propelled Mower – Best Overall
The EGO Power+ LM2102SP-A absolutely dominates the cordless mower conversation with its variable-speed self-propulsion that glides from leisurely 0.9 MPH strolls to brisk 3.1 MPH power-walks. This 21-inch steel deck beast tackles everything from manicured suburban lawns to unruly patches that would make gas mowers sweat, all while delivering an impressive 65 minutes of continuous runtime from its dual 4.0Ah batteries.

How to Choose the Right Cordless Lawn Mower
Runtime & Battery Voltage
The heart of a cordless lawn mower is its battery. Battery voltage (40V, 60V, 80V) generally correlates with power – higher voltage usually means the mower can tackle thicker grass and challenging terrain more effectively. However, runtime is equally crucial. Runtime, measured in minutes, dictates how much lawn you can cover on a single charge. Consider your lawn size. Smaller yards (under 1/4 acre) can often manage with 40V systems and 30-45 minutes of runtime. Larger lawns (1/2 acre or more) benefit from 60V or 80V mowers offering 60+ minutes, or those with dual-battery compatibility for uninterrupted operation. Look for models that include two batteries or have the option to purchase a second, as this is a significant convenience.
Self-Propelled vs. Push Mowers
Self-propelled mowers take the effort out of mowing, especially on hills or larger lawns. These models use a motor to drive the wheels, reducing physical strain. Variable speed self-propel is a valuable feature, allowing you to adjust the pace to your walking speed and grass conditions. Push mowers are lighter and more affordable, suitable for smaller, flat yards. Consider your physical fitness and lawn terrain when deciding. If you have a sloped yard, a self-propelled model is highly recommended.
Cutting Deck Size & Features
The cutting deck size (typically 16-21 inches) affects mowing efficiency. A wider deck covers more ground with each pass, speeding up the process. However, larger decks can be harder to maneuver in tight spaces. Beyond size, consider the cutting features:
- Mulching: Returns finely chopped grass clippings to the lawn as fertilizer.
- Bagging: Collects clippings for a cleaner look.
- Side Discharge: Ejects clippings to the side, suitable for taller grass or when you don’t want to mulch or bag.
- Cutting Height Adjustment: The range and ease of adjustment are important for achieving your desired grass length. Single-lever adjustments are generally more convenient.
Motor Type and Additional Conveniences
Brushless motors are becoming increasingly common in cordless mowers. They offer several advantages over brushed motors, including longer lifespan, higher efficiency, and quieter operation. Other features to consider:
- LED Headlights: Useful for mowing in low-light conditions.
- Vertical Storage: Saves valuable garage space.
- Water Resistance (IPX Rating): Protects the mower from the elements.
- Quick Start: Push-button start is a convenient feature.
- Touch Drive: Control the speed of the mower with a touch.
