However, the rise of electric lawn mowers has introduced a compelling alternative, sparking a debate about which option is superior. Both types offer distinct advantages and drawbacks, and the best choice depends on individual needs, yard size, and priorities such as environmental impact, cost, and ease of use. This comprehensive guide explores the pros and cons of electric and gas-powered lawn mowers to help you make an informed decision.
The Evolution of Lawn Mowers
Historically, lawn mowers were exclusively gas-powered, relying on internal combustion engines that required a pull-start and regular maintenance. These machines were powerful, capable of tackling large lawns and thick grass, but they came with significant downsides, including noise, emissions, and upkeep. Over time, advancements in battery technology and electric motors have given rise to electric lawn mowers, which offer a quieter, cleaner, and often more user-friendly alternative. Today, consumers face a choice between these two technologies, each with its own set of benefits and limitations.
Electric Lawn Mowers: Pros and Cons
Electric lawn mowers come in two primary forms: corded and cordless (battery-powered). They have gained popularity due to their eco-friendliness and ease of use, but they are not without their challenges. Below is a detailed breakdown of their advantages and disadvantages.
Pros of Electric Lawn Mowers
1. Quieter Operation
One of the most significant advantages of electric lawn mowers is their reduced noise levels. Gas-powered mowers typically operate at around 95 decibels, comparable to a motorcycle, which can be disruptive to both the user and neighbors. In contrast, electric mowers produce approximately 75 decibels, similar to the sound of a washing machine. This quieter operation makes them ideal for suburban environments where minimizing noise pollution is a priority.
2. Lower Maintenance
Electric mowers require significantly less maintenance than their gas-powered counterparts. Gas mowers demand regular upkeep, including oil changes, spark plug replacements, and air filter cleanings. Electric models, however, have fewer moving parts and no engine components that need such attention. This reduction in maintenance not only saves time but also reduces long-term costs, making electric mowers more economical over their lifespan.
3. Easier to Maneuver
Electric lawn mowers are generally lighter than gas-powered models, which makes them easier to push and navigate around tight corners or obstacles. For example, a popular cordless model like the EGO Power Plus 56-Volt 21-inch mower weighs just 62.6 pounds, while a comparable gas-powered mower, such as the Craftsman M250 with a Honda engine, weighs 90 pounds. This lightweight design is particularly beneficial for users with smaller yards or those who may struggle with heavier equipment.
4. Environmentally Friendly
Gas-powered mowers are notorious for their environmental impact, emitting pollutants such as carbon monoxide, nitrogen oxides, and volatile organic compounds. According to the California Air Resources Board, operating a gas mower for one hour produces the same amount of pollution as driving a car for 300 miles. The Environmental Protection Agency (EPA) also notes that gas mowers account for a significant portion of non-road-related air pollution in the United States. Electric mowers, by contrast, produce no tailpipe emissions during operation. The Electric Power Research Institute estimates that replacing half of the gas mowers in use with electric models could reduce emissions equivalent to removing two million cars from the road.
5. Potentially Lower Cost
While the upfront cost of electric mowers can vary, they often prove more cost-effective over time. Basic electric models can start at prices as low as $100, though most quality push mowers range from $250 to $550. Gas mowers typically start at $200 to $250, with popular models often priced between $400 and $1,000, and riding mowers reaching up to $2,500. Additionally, electric mowers eliminate the need for gasoline and reduce maintenance expenses, leading to significant savings over years of use.
Cons of Electric Lawn Mowers

One of the primary limitations of electric mowers is their run time, particularly for battery-powered models. Most cordless electric mowers offer run times between 20 and 60 minutes per charge, which is sufficient for small to medium-sized lawns (up to half an acre). However, for larger yards, this limitation can be a significant drawback. Corded models provide unlimited run time but come with the inconvenience of managing a cord, which can restrict mobility and pose a tripping hazard. For cordless models, users may need to purchase an additional battery to extend mowing time, adding to the overall cost.
2. Not Ideal for Larger Yards
Electric mowers are less suited for large or hilly yards. While electric riding mowers, such as the Ryobi 42-inch Battery Electric Riding Zero Turn Mower, are available, they still fall short of the capabilities of gas-powered riding mowers like the Toro IronForged Deck Zero Turn, which boasts a 60-inch cutting width and greater power. For expansive properties, gas mowers remain the more practical choice due to their longer run times and ability to handle demanding terrain.
3. Reduced Power
Electric mowers generally produce less torque than gas-powered models, which impacts their performance on challenging terrain or thick grass. Torque, the force that drives the blade’s rotation, averages 2 to 2.5 pound-feet for electric mowers, compared to 4.5 to 8.75 pound-feet for gas mowers. This disparity means gas mowers are better equipped to handle hills, dips, and dense vegetation, while electric models may struggle in these conditions.
