10 Best Small Electric Lawn Mowers 2025 in the United States

The Greenworks 40V 16" Cordless Lawn Mower is a solid choice for small to medium-sized lawns up to ½ acre. One of its strengths is its convenience and ease of use, thanks to the cordless design and push button start. The 40V 4.0Ah battery offers up to 45 minutes of runtime, which should be sufficient for smaller lawns, and it fully charges in a reasonable 120 minutes. The lightweight design, at 37.5 pounds, makes it easy to maneuver, which is great for users who may not want the heaviness of traditional gas mowers.

The 16-inch cutting width is suitable for smaller yards, and the mower includes a 5-position height adjustment (1-1/4" to 3-3/8") to handle different grass lengths and types effectively. Another notable feature is the 2-in-1 grass management option, which allows for both mulching and rear bagging. This adds versatility depending on your lawn care preferences. Additionally, the mower is virtually maintenance-free with no need for gas or oil, and it operates quietly without emissions, making it environmentally friendly.

This mower may not be ideal for larger lawns due to its limited battery life and smaller cutting width. Users with larger properties may find the battery runtime insufficient and may need additional batteries to complete the job in one go. Also, the plastic construction might not be as durable as metal alternatives. In conclusion, this mower is best suited for environmentally conscious homeowners with small to medium-sized yards who value ease of use and low maintenance.

The Greenworks 60V 21” Cordless Lawn Mower is a solid choice for small to medium-sized lawns, offering the convenience of cordless operation without sacrificing power. With a 21-inch cutting width, it covers ground efficiently, making it suitable for yards up to 1/2 acre. The included 5.0Ah battery provides up to 60 minutes of run-time, which is generally sufficient for most small lawns, and the dual port auto switch feature allows for continuous mowing with an additional battery (sold separately).

The mower generates 50% more power than 40V systems and operates with 60% less noise compared to traditional gas mowers, making it a quieter, eco-friendly option with fewer emissions and no fumes. Its IPX 4 waterproof rating ensures durability even in tough weather conditions. However, at 59.5 pounds, it may be heavier than some other models, which could affect maneuverability for some users.

The mower features five cutting height adjustments, providing flexibility to achieve the desired lawn height. Maintenance is relatively low thanks to its electric power source, eliminating the need for oil changes or fuel storage. Potential users should consider the initial investment in additional batteries for extended run-time and the weight if easy maneuverability is a priority.

With a 20-inch cutting width, it is suitable for yards up to 1/2 acre, making it a good fit for medium-sized lawns. The 40V battery system delivers ample power and the convenience of being compatible with over 140 other WORX PowerShare tools is a significant advantage. The included batteries are designed for durability, resisting heat and impact, and come with a charge-level indicator for easy monitoring of remaining power.

This mower also includes 7-position cutting height adjustment (from 1.5" to 4.25"), which provides flexibility for different grass lengths and conditions. Additionally, the 3-in-1 cutting modes (bagging, mulching, and side discharge) enhance versatility in grass management. The collapsible handle allows for compact storage, which is a practical feature for those with limited space.

At 61.6 pounds, the mower may be slightly heavy for some users, potentially affecting maneuverability. While the battery life is decent, users with larger lawns might find themselves needing to recharge more frequently.

Maintenance is minimal due to the absence of a gas engine, though periodic battery care is required. The Worx Nitro 40V 20" Cordless Lawn Mower is a solid choice for those seeking a powerful, versatile, and eco-friendly mowing solution for medium-sized lawns, with the primary trade-offs being its weight and occasional battery recharges for larger areas.
