Gas vs Electric Lawn Mowers

Gas or Battery Lawn Mowers: Which is Best?

Gas or electric lawn mowers – which is a better fit for your lifestyle and your yard? Here at Greenworks, it’s no surprise which side of the fence we’re on – and we’re excited to weigh in on the great lawn mower battery versus gas-powered debate.


Are Electric Lawn Mowers Better Than Gas?

As a battery tech company, we’ve spent the last 20 years developing and advancing battery powered technology. We’ve set out to outperform gas-powered market leaders without the noisy fume-spouting, gas-guzzling downsides. So why do we think battery powered lawn mowers win the gas vs electric mower battle?

Let’s dive into some lawn mower considerations and why we think battery power is the way to go.


Electric Mowers Tackle the Toughest Jobs ... with Power to Spare!

The power story has long favored gas-powered lawn mowers, but the truth is electric motors produce the same blade speed and cut quality as gas mowers – but without loss of efficiency, harmful emissions and maintenance costs.

Did you know that the technology that goes into a battery-powered motor mower is completely different from a gas-powered lawn mower? We’re used to thinking that horsepower is the key measurement of lawn mowing performance – but horsepower doesn’t tell the whole story of lawn mower power.

All lawn mowers, both gas and electric, are fueled by a power source. The difference lies in what kind of fuel is used and how the energy is transferred to make the motor run.


Gas-burning mowers combine a mixture of air and gas that is ignited with a spark to create a mini explosion – which is then harnessed to power the mower. These mini- explosions can result in sparks, especially dangerous in dry areas of the country that are prone to wildfires.

Electric lawn mowers utilize magnets (or carbon brushes) and electromagnets instead of relying on sparks and gas. The magnets interact and energize metal coils that move the rotor. This mechanism is powered by electricity provided by batteries, or in some cases, a cord plugged into a power source. Battery-powered lawn mowers with brushless motors like Greenworks use the placement of the electromagnets to eliminate the need for carbon brushes - creating an even more powerful, efficient, and long-lasting motor. 


You read that right: your battery-powered lawn mower runs on magnets. It’s power- packed and sustainable!

How it Works: Gas vs Electric Lawn Mowers

  Gas-burning Electric powered
Motor powered by Mini explosions made from combining gas, air, and sparks

Magnet powered! Zero sparks or explosions needed

Fuel Gasoline Electricity via batteries (or cord)

Breathable Air

One gas mower spews 34 lbs. of pollutants (and 88lbs CO2) into the air every year. (EPA) 0% emissions means zero harmful air is breathed


Brushless Motors Make Your Electric Mower Work Smarter, Not Harder

The superior performance of a battery-powered lawn mower comes from the brushless motor (yay, magnets!) – aided by a smart sensing microchip that efficiently uses the available battery power. When you hit tall, wet or thick grass, your Greenworks electric mower senses the resistance and automatically adjusts.

This smart sensing technology draws more power from the battery, increasing the blade speed to ensure a clean, consistent cut. Thanks to this innovative technology, battery- powered lawn mowers are actually less likely to bog down than the gas powered mower equivalent.

Most of the time – especially in yards that are regularly maintained – extra power is just not necessary. When less power is needed, the smart sensor helps to conserve energy – extending your mower’s runtime and your productivity.


Blade Speed & Cut Quality

Blade speed and cut quality are more accurate indicators of lawn mower performance. After all, getting the job done well and with energy to spare is the end goal!

Electric motors have the ability to maintain a high blade speed when needed – and to conserve energy when it’s not. For example, a Greenworks lawn mower with SmartCut technology may have a blade speed of 2800 rpm, but will auto adjust to 3200 rpm (and maintain that speed even under load) when needed to ensure a clean cut. Many models have a turbo button that allows you to manually control the amount of power as well.



How Long Do Battery-powered Electric Lawn Mowers Last?

Runtimes for both types of lawn mowers are directly related to the capacity of the power source, whether that be a fuel tank or battery capacity. Fuel tanks in gas mowers range somewhere between 1-3 quarts. Measuring capacity and runtimes for cordless mowers is slightly more complicated since there are several factors that contribute to the battery life including:

●  Amount of power - Thick or tall grass will require the motor to draw more power from the battery
●  Brushless motor vs brushed - Brushless motors are significantly more efficient so you can mow longer
●  Watt hours (Battery Voltage x Amp hours) - Higher wattage indicates more available power giving longer battery life

Whether you’re mowing a small space, or tackling acreage, Greenworks lawn mowers are available in 24V, 60V, and 80V options.

Make Mowing More Manageable

Why make life harder than it needs to be? Cordless lawn mowers are so easy to use – and easy on your wallet, too. Check out some of the perks of effortless mowing with Greenworks:

●  Effortless: Our mowers are lightweight for easy maneuverability – meaning less vibration and fatigue to help you get the job done quickly.
●  Less noise: Everyone has a neighbor with a deafening lawn mower – but you can show your street how it’s done with Greenworks. Electric mowers are significantly quieter and typically stay well below noise pollution guidelines.
●  Maintenance: Did we mention no oil changes, air filters, belts, carburetors or spark plugs to replace? Save on yearly tune-up costs with Greenworks.
●  Operation: Greenworks electric mowers are easy to start – no more wrestling with pull cords.
●  Skip the fuel: Avoid high fueling costs (and gas spillages – no one wants to smell like a gas station!) each time your lawn needs to be mowed. Simply drop in the mower batteries and start mowing.
