Is Buying an Electric Lawn Mower in 2023 Worth It? Here Are the Pros and Cons

Compared to gas-powered lawn mowers, electric models are cleaner, quieter and greener.- but there are some drawbacks.

For decades, lawn mowers were gas-guzzling and emissions-spouting beasts that were hard to pull-start and loud enough to wake up the neighborhood. But a new generation of electric-powered models is changing the lawn care game.

Though gas-powered models still dominate the aisles of big-box stores, a growing number of affordable electric mowers now provide a compelling alternative, whether your priority is power, convenience or sustainability. If you’re in the market, you have more options than ever.- and the best electric mowers are now good enough to rival their gas-powered competitors. We’ll break down the pros and cons of electric and gas mowers to help guide your buying decision.

Pro: Electric lawn mowers are quieter

Lawn mowers are loud. While standard gas-powered mowers usually operate at 95 decibels.- equivalent to the racket made by a motorcycle revving its engine.- electric mowers max out at around 75 decibels on average, closer to the din of a washing machine. If you live in a neighborhood, an electric mower is the less disruptive option.

Con: Shorter run times

Once you start mowing, you want the job done in one fell swoop.- but that might not be possible with an electric lawn mower, especially if you have a significant plot of land. Electric models top out at between 45 to 60 minutes per charge, which should be enough to handle up to half an acre of grass.

Some electric mowers, like this corded Sun Joe hover model will provide unlimited mowing time, as long as you have a power source or long enough extension cord. Most electric models run on batteries, however, and offer run times ranging from 20 to 45 minutes. If it takes you longer to mow your yard, that’s going to be a problem.- or a delay, at least, while you recharge. You can keep a second battery on hand, but that’ll require an additional purchase.

Pro: Easier to maneuver and less maintenance

A gas-powered mower requires periodic maintenance, including the eventual replacement of a spark plug, oil filter and air filter. Electric mower components, however, require less regular servicing, which should increase your savings over the long term. In this way, an electric model can be more economical than a gas-powered counterpart.

Most electric mowers are also relatively lightweight, making them easier to navigate across your lawn and maneuver around tight corners. Our top electric pick, the EGO Power Plus, weighs 62.6 pounds.- making it considerably lighter than the Craftsman M250, which weighs in at a hefty 90 pounds. Though the self-propelled engine improves maneuverability when you’re cutting the grass, the mower is still heavy to push.

Pro: Better for the environment

Gasoline-powered engines produce a surprising amount of carbon emissions and a slew of pollutants. According to the California Air Resources Board, one hour of mowing generates the same pollution as driving a car for 300 miles. And the Environmental Protection Agency says that gas lawn mowers contribute the majority of non-road-related air pollution generated nationwide.

Electric lawn mowers are a much cleaner, energy-efficient alternative. The Electric Power Research Institute notes that if we replaced half the gas-powered lawn mowers with electric models, it would reduce the same amount of emissions as removing 2 million vehicles from the road. This is certainly an important factor to consider when purchasing a new mower.

Con: Electric lawn mowers aren’t as powerful

Lawn mower power is measured by a torque rating, which quantifies the driving force behind the blade’s rotation. The higher the torque rating, the more powerful the chopping motion.- and the less likely the mower is to get stuck or caught up on a clump of grass or other obstruction.

The average electric lawn mower has between 2 and 2.5 pound-feet of torque. The average of a gas-powered mower is between 4.5 and 8.75 pound-feet, which is about three times more power. This means a gas-powered mower will make it easier to tackle challenging terrain like hills and dips and slants in your yard. And homeowners with larger lawns or yards with hills or slopes may require heavier duty equipment like a riding lawn mower. While most riding lawn mowers are gas-powered, there are electric ones on the market, like this Ryobi model.

Pro: They can be less expensive

If you’re in the market for a new mower, a basic electric mower is less expensive than a basic gas mower.

Electric models can start as low as about 100, the price for the Sun Joe hover model tested by CNET experts, but that’s a particularly low-priced outlier. Most push-from-behind electric models can cost anywhere from 250 to 550.

for gas-powered mowers can start at around 200-250. But the most popular lawn mower brands have basic gas-powered models that fall into the 400 to 1,00 price range. Certain gas riding lawn mowers can even reach up to 2,500.

Final thoughts

Overall, the lawn mower market continues to expand, with an array of diverse offerings. For homeowners with larger yards, gas-powered mowers may still be the best fit, since they have the durability and power to tackle bigger lawns with ease. That’s if you’re comfortable with the environmental impact gas mowers have.

If you want to maintain a midsize yard, reduce your carbon footprint (and even save some money) in the process, then an electric lawn mower is probably the best for your needs. Either route you take can help you gain a healthy-looking lawn that boosts the curb appeal and value of your home.

NIU BQi-C3 Pro e-bike with 90-mile range 900 off in New Green Deals, Greenworks e-mowers, more

Friday has one of the best e-bike offers we’ve seen all year now on tap. The recently-released NIU BQi-C3 Pro e-bike is now clocking in at a new all-time low thanks to a 900 discount. That’s joined by a new Christmas in July savings event with popular electric tools seeing steep discounts, alongside much of the same on the latest Eve Aqua HomeKit faucet for helping grow out a gorgeous lawn in the first place.

Save 900 on the NIU BQi-C3 Pro e-bike

Courtesy of Best Buy today, your ticket to affordable summer e-bike joyrides is here. The NIU BQi-C3 Pro e-bike normally sells for 2,200, but now it’s seeing one of the best discounts to date at 1,299.99 shipped. Available in three different designs, the EV comes with 900 in savings just in time to ride out the last few months of warm weather. It’s also a new all-time low, period.

Everything for this e-bike comes centered around a step-through design that makes it easier to mount and dismount compared to some other form-factors. Then backed by a 920Wh drivetrain, the NIU BQi-C3 Pro is backed by a Gates carbon belt drive that helps keep maintenance to a minimum. There’s also an impressive 90-mile range that lets this model travel at up to 28 MPH in pedal assist mode. Though my favorite feature has to be the swappable twin batteries. While its massive range is already exciting in its own right, the ability to refuel just by clicking out the fuel cell makes it that much easier to keep juiced up. Our hands-on review breaks down the rest of the feature set if you’re not already sold.

A smoking lawn mower is never a good sign. Whether the smoke is blue, white, or black, here’s how to identity and address the issue without the help of a professional.

Q: Recently, my mower started billowing smoke when I powered it up, so I shut it off immediately. Why is my lawn mower smoking? And is it a fire hazard? I want to know how to proceed so I don’t harm the machine.

A: Your lawn mower can emit smoke for numerous reasons—many of which don’t require the services of an expert. A homeowner can usually identify the reason for a smoking lawn mower by gauging the color of the Cloud coming around the engine, then fix it accordingly before lasting damage occurs. Keep in mind that all mowers with internal combustion engines contain the same basic parts, but the configuration of those parts varies widely, depending on manufacturer and model. Consult your owner’s manual if you’re unsure how to access a specific part of your lawn mower’s engine.

White or blue smoke may indicate an oil spill on the engine.

If you’ve recently changed the oil in your mower and the engine is emitting white or blue smoke, it’s possible that some of the oil spilled onto the engine. Similarly, you could’ve spilled oil on the engine by mowing on a slope greater than 15 degrees or tipping the mower on its side. The smoke may look disconcerting, but it’s completely harmless. Solve the problem by restarting the mower and allowing the spilled oil to burn off. If you tip the mower often for cleaning or maintenance, check your owner’s manual to determine the best way to reduce the risk of oil leaks.

An overfull oil reservoir may also cause white or blue smoke.

Ensure you didn’t overfill the mower by checking the oil level with the dipstick located on the reservoir. To do this, remove the dipstick cap, wipe off the stick with a rag, and reinsert it into the reservoir. Then remove the dipstick once again and determine the oil level in comparison to the recommended “fill” line on the stick. If the level is too high, drain the oil (consult your owner’s manual for instructions), then refill the reservoir with it. Start checking the oil level with the dipstick after you’ve added about ¾ of the amount recommended in the manual. Continue to add small amounts of oil until the level matches the recommended “fill” line. Also note that using the wrong grade of engine oil may cause blue or white smoke. Consult the owner’s manual for the exact type of oil recommended for your mower.

Black smoke may indicate that the mower is “running rich,” or burning too much gasoline.

Your lawn mower’s carburetor regulates the ratio of gasoline to air mixture. If the carburetor isn’t getting enough air, the mixture has a higher percentage of gasoline, which can create black exhaust smoke. It’s possible that a dirty or clogged air filter is preventing sufficient airflow into the carburetor. Try replacing the air filter. (Note: air filters vary by mower model; view example air filter on Amazon.) Next, run your lawn mower for a few minutes. If the black smoke still appears, the carburetor might need to be adjusted in order to increase airflow. Either take the mower to a professional or adjust the carburetor yourself with instructions in your owner’s manual.

Take your mower to a repair shop if necessary.

If the previous steps don’t correct blue or white smoke, your mower could have a more serious problem, such as an air leak in the crankshaft (the cast iron or cast aluminum case that protects the moving parts of a mower’s engine). Continuing blue or white smoke could also indicate that some of the engine’s components or seals are worn out and need replacement. Similarly, if black smoking still persists after you’ve replaced the air filter and adjusted the carburetor, you could be facing a more serious mechanical issue. All of these problems require the help of a professional. If your mower is still under warranty, check with the manufacturer for the location of the nearest servicing dealer; problems stemming from a factory defect or poor workmanship may garner free repairs. If your mower is not covered under warranty, a reputable small-engine repair shop should also be sufficient to get the job done.
