While some battery-powered mowers claim to be just as good as gas mowers, in the real world the differences become clear. Only gas-powered mowers provide the power you need to get the job done right. So if you’re trying to decide between gas and battery, there are a few things you should keep in mind.

Engine Horsepower

Horsepower is everything.

Battery-powered mowers like to make claims about having “gas-like” torque, but the truth of the matter is that “gas-like” torque isn’t the same as real gas torque. How so? Because while a manufacturer might provide the torque rating of an electric motor, that torque will decline as the load on it is increased, such as when trying to mow thick grass. Also, don’t be misled by manufacturers trying to equate a battery’s capacity with power. That’s like assessing the power of a car’s engine by the size of its gas tank. When it comes to measuring the ability of an engine to sustain the torque necessary to spin a blade fast enough to cut grass effectively, there’s no better measure than horsepower.

Waiting isn't working.

Trying to mow thick or damp grass can drain a battery even more quickly. Which means either waiting for it to recharge or purchasing additional costly batteries. Also, to avoid stalling in thick grass, some battery-powered mowers must be pushed more slowly, which can also add to the time it takes to get the job done.

Gas-powered mowers tackle any conditions

Up to any challenge.

No matter the size of your lawn or how uneven it might be. No matter if you mulch clippings and leaves. No matter if your grass grows a little quicker and thicker than expected. Only a gas engine can generate the sustained power it takes to get your lawn mowed with the performance that you expect in any condition.


Gas engines provide the power for a more quality cut.

Cutting grass, not corners.

Because batteries have a short run time and take a long time to recharge, some manufacturers reduce the lift and cutting performance of their blades in an effort to reduce the power needed to spin them. Unfortunately, this compromises the blade’s ability to create air flow that stands grass up for a cleaner cut. This results in a patchy, uneven appearance. If you want a quality cut, get your hands on a gas-powered engine that can handle an aggressively contoured or shaped blade.

Greater power options with gas-powered mowers.

Gas power fits all.

Your yard is unique and not just any lawnmower will do. Because gas engines offer a greater breadth of power options, you have the freedom to select a mower that fits your needs. So if you’re looking for a self-propelled mower, one that can truly handle capabilities such as 3-in-1 mulching, side discharge, or bagging, or provides the power to climb hills and any rough terrain, gas is for you.

Leading through innovation.

At Briggs & Stratton, we work incredibly hard to make the work you do easier and the experience better than with older engines. Nowhere is our commitment to cutting-edge technology more apparent than in our current line-up of gas lawnmower engines. They foldaway to allow for space-saving storage, eliminate the need for messy and time-consuming oil changes*, and start with the push of a button. We even offer powerful gas engines that provide a 50% quieter mowing experience** so you can cut grass any time of the day without worrying about bothering the neighbors. No wonder battery-powered mowers are always trying to play catch-up.

Fueling an environmental discussion.

Although battery-powered mowers themselves have zero emissions, there’s a good chance the electricity used to charge them came from a power plant that burns fossil fuels. 67% of our country’s power plants do. Plus, lithium-ion batteries have a lifespan of only a few years and after that, must be disposed of properly to prevent the release of hazardous materials into landfills.

Gas engines are cleaner than ever before.

Gas engines are cleaner and greener than ever.

Thanks to significant investment of resources into engineering and research, we have cut emissions by 80% over the last 30 years. Briggs & Stratton has made environmental stewardship a priority – from engineering our most fuel-efficient lineup of gas engines ever through electronic fuel injection (EFI) technology to our commitment to reducing energy use across our manufacturing and corporate operations. You see, it’s not enough for us to help make lawns beautiful today; we care about helping make the planet a greener place for future generations.
