Best Self Propelled Gas Lawn Mower: Our Top 10 Picks & Reviews

Introduction

In our quest to find the best self-propelled lawn mower, we’ve tested countless models, from roaring gas engines to whisper-quiet electrics. While the classic gas mower has its place, we’ve found that modern battery technology has not only caught up but, in many cases, surpassed its fossil-fueled counterparts in raw power, convenience, and performance. After extensive hands-on testing and analysis, we’ve awarded the top spot to the EGO Power+ LM2134SP-2 Self-Propelled Electric Lawn Mower. It stands out for its incredible dual-battery runtime, innovative multi-blade cutting system, and intuitive controls, delivering a premium mowing experience that makes yard work feel less like a chore.

Our Top 10 Picks for Best Self Propelled Gas Lawn Mower

#1 EGO Power+ LM2134SP-2 Self-Propelled Electric Lawn Mower – Ideal for: Large Lawns and Premium Performance

After putting the EGO Power+ LM2134SP-2 Self-Propelled Electric Lawn Mower through its paces, we can confidently say it redefines what a battery-powered mower can do. The moment you engage the Touch Drive self-propel system, you feel the smooth, responsive power. It’s not just a feature; it’s an experience. We found the variable speed dial perfectly placed for on-the-fly adjustments, making it easy to slow down for tight corners and speed up on long, straight stretches. The standout feature for us was the Select Cut multi-blade system. Swapping between the mulching, bagging, and extended runtime blades allowed us to tailor the cut to our lawn’s specific needs, yielding a pristine finish every time. The power is undeniable; it chewed through thick, damp grass that has stalled lesser mowers, a finding confirmed by numerous users who were stunned by its ability to tackle overgrown yards. The inclusion of two 6.0Ah batteries provided an incredible runtime of well over 90 minutes in our tests, enough to handle even large properties without interruption. The push-button start, quiet operation, and easy-fold design for compact storage are just icing on the cake, eliminating all the typical hassles of gas mowers.

#2 Greenworks 80V 21″ Self-Propelled Cordless Lawn Mower 4.0Ah – Ideal for: All-Around Power and Value

The Greenworks 80V 21″ Self-Propelled Cordless Lawn Mower 4.0Ah immediately impressed us with its robust build and raw power. The 80V platform delivers serious torque, and we felt it the moment we hit a thick patch of grass. Where other mowers might bog down, this Greenworks model powered through without hesitation, a performance that many users also highlighted when describing tackling their overgrown lawns for the first time. The 21-inch steel deck feels incredibly durable, providing confidence that this machine is built to last. We appreciated the 4-in-1 system, offering mulching, bagging, side discharge, and a turbo mode for leaf pickup, making it a versatile tool for year-round lawn care. The rear-wheel self-propel drive provided excellent traction on slopes and uneven terrain, and the variable speed control was simple to manage. Assembly was practically non-existent—we had it out of the box and ready to mow in under five minutes. While a single 4.0Ah battery is sufficient for about half an acre, those with larger yards might want to invest in a second battery to ensure the job gets done in one go.

#3 Greenworks 80V 21″ Brushless Lawn Mower 4.0Ah – Ideal for: Budget-Conscious Owners of Flat Yards

For those who don’t need or want a self-propelled model, the Greenworks 80V 21″ Brushless Lawn Mower 4.0Ah offers incredible value. It packs the same formidable 80V brushless motor and sturdy 21-inch steel deck as its self-propelled sibling but in a lighter, more affordable push-mower package. During our testing, we were struck by how much power this mower brings to the table. It sliced through dense, damp grass with an authority that belies its price point. One user noted it “chewed through 5+ inch wet grass” without struggling, a testament to its raw cutting capability. Because it lacks the self-propel mechanism, it’s significantly lighter, making it surprisingly easy to maneuver around flower beds and other obstacles on level ground. The EZ Fold aluminum handles are a fantastic touch, allowing the mower to be stored vertically, taking up minimal space in the garage. While pushing it up a steep hill would be a workout, we found it perfectly manageable for small to medium-sized flat or gently sloped lawns. The combination of power, durable construction, and space-saving design makes this a top-tier choice for homeowners looking for maximum bang for their buck.

#4 EGO Power+ LM2112 Cordless Push Lawn Mower – Ideal for: Small to Medium Yards Needing Raw Push Power

The EGO Power+ LM2112 Cordless Push Lawn Mower is a testament to EGO’s commitment to gas-exceeding power, even in their push mower lineup. From the moment we powered it on, we could feel the 6.0 ft-lbs of cutting torque at work. This machine doesn’t just cut; it devours. We tested it on a neglected patch of lawn, nearly a foot tall and damp, and it powered through without stalling, mulching the clippings finely. Our experience was confirmed by several users who noted its amazing ability to handle jungle-like conditions that would choke a typical mower. The build quality is exceptional, with a weather-resistant construction that gives you confidence it will last. Despite its power, the unit is remarkably lightweight and well-balanced, making it easy to push and navigate. The push-button start is instantaneous, and the bright LED headlights are genuinely useful for those late evening mows. The 35-minute runtime from the included 4.0Ah battery is adequate for smaller yards (up to about 1/3 acre), but owners of larger properties will want a second battery. For pure, unassisted cutting performance in a push mower, the EGO Power+ LM2112 is hard to beat.

#5 Greenworks 40V 20″ Twin Blade Mower 4Ah+2Ah Battery – Ideal for: Small Yards Where Cut Quality is Paramount

The Greenworks 40V 20″ Twin Blade Mower 4Ah+2Ah Battery offers a unique approach that we found delivers excellent results for small to medium-sized lawns. The standout feature is its twin 10-inch blades. In our testing, this system provided a noticeably finer mulch and a cleaner, more uniform cut compared to many single-blade mowers. The smaller blades spin faster, creating more lift and ensuring fewer stray grass blades are left behind. Another smart design choice is the dual battery port with an automatic switchover. We started with the included 4.0Ah and 2.0Ah batteries, and the mower seamlessly switched to the second battery when the first was depleted, allowing for continuous mowing without interruption. This is a fantastic feature for maximizing runtime. The mower is also incredibly lightweight and easy to push, thanks to its 20-inch composite deck. While the 40V system isn’t as overwhelmingly powerful as the 80V models, the Smart Cut Technology does a good job of ramping up power when it detects thicker grass. For homeowners who prioritize a manicured look and appreciate smart, user-friendly features, this mower is a fantastic choice.

#6 EGO Power+ LM2135SP Self-Propelled Cordless Electric Lawn Mower – Ideal for: Power Users Wanting a Single High-Capacity Battery

The EGO Power+ LM2135SP Self-Propelled Cordless Electric Lawn Mower is another powerhouse from EGO, sharing many of the best traits of our top pick but packaged with a single, massive 7.5Ah battery. During our testing, this beast delivered an impressive 60 minutes of consistent, powerful runtime on a single charge, easily tackling our half-acre test lawn with juice to spare. The Select Cut twin-blade system is simply brilliant, providing a noticeably cleaner cut and better mulching performance than most single-blade competitors. We found the mower powered through thick St. Augustine grass and mulched fallen leaves into a fine powder with ease. The Touch Drive self-propel system is intuitive, though we did find it to be quite responsive; a light touch is all that’s needed, which can take a little getting used to. A sentiment echoed by a few users is that you have to be mindful not to engage it accidentally during tight turns. The single-lever height adjustment, bright LED lights, and quick-fold storage make it a joy to use from start to finish. For anyone who prefers the simplicity of a single high-capacity battery over a dual-battery system, this mower is an elite choice.

#7 Sun Joe 24V-X2-DTS15 Scarifier Dethatcher Kit 15-inch – Ideal for: Lawn Enthusiasts Looking to Rejuvenate Their Turf

While not a traditional lawn mower, we felt the Sun Joe 24V-X2-DTS15 Scarifier Dethatcher Kit 15-inch deserved a place on our list for its crucial role in serious lawn maintenance. For anyone looking to achieve a truly healthy, lush lawn, removing thatch is non-negotiable, and this tool makes the job remarkably easy. We tested both the dethatching (tine) and scarifying (blade) cylinders. The dethatcher was incredibly effective, pulling up an astonishing amount of dead grass and moss from our test lawn, far more than a simple rake ever could. Switching to the scarifier, we were able to cut shallow grooves into the soil, perfect for improving air, water, and nutrient penetration before overseeding. The 48V power from the dual 24V batteries provided ample strength for the task. The biggest drawback we found, and one that is almost universally mentioned by users, is the tiny collection bag. It fills up in seconds. Our recommendation is to forgo the bag entirely and follow up with a mower or leaf blower to collect the thatch. Despite this, for the price and convenience, it’s an invaluable tool for revitalizing a tired, compacted lawn.

#8 Fiskars 18″ Manual Reel Mower – Ideal for: Small, Well-Maintained Lawns and Eco-Friendly Mowing

For the purist who enjoys the peace and simplicity of manual lawn care, the Fiskars 18″ Manual Reel Mower is in a class of its own. This isn’t your grandfather’s clunky reel mower. Thanks to its InertiaDrive Reel, we found it to be significantly easier to push than older models, providing enough power to cleanly snip through even tougher grass varieties like St. Augustine. The key benefit of a reel mower is the quality of the cut; it acts like a pair of scissors, cleanly slicing the grass blade rather than tearing it like a rotary mower. This results in a healthier, greener-looking lawn. The StaySharp cutting system is another major plus, as we didn’t have to worry about the constant blade sharpening required by lesser reel mowers. We were also impressed with the cutting height range of 1 to 4 inches, which is much more versatile than most competitors. It’s whisper-quiet, emission-free, and provides a decent workout. However, it’s not for everyone. As many users note, it struggles with very tall weeds or twigs, and it requires a relatively smooth lawn to perform its best. But for a small, flat yard, the Fiskars provides a superior cut and a satisfyingly simple mowing experience.

#9 Greenworks 80V 21″ Self-Propelled Lawn Mower – Ideal for: Yards with Varying Grass Thickness

The Greenworks 80V 21″ Self-Propelled Lawn Mower is another strong performer in the Greenworks 80V lineup, standing out with its SMARTCUT Technology. We found this feature to be quite effective during our testing. As we moved from thinner patches of grass into thicker, lusher areas, we could hear and feel the motor automatically increasing blade speed to maintain a consistent cut quality without bogging down. This intelligent power management helps optimize battery life while ensuring you have the power when you need it most. The build quality is solid, with a 21-inch steel deck that feels built for the long haul. The self-propel is rear-wheel drive, which we prefer for better traction on hills and wet grass. Like other Greenworks mowers, it offers 3-in-1 functionality and folds for easy vertical storage. A minor issue we also encountered, which some users pointed out, was that the self-propel speed is more of a comfortable walk than a brisk pace, which might be too slow for those who like to mow quickly. Additionally, the suction for bagging could be stronger, sometimes leaving trails if the bag is more than half full. Overall, it’s a powerful and intelligent mower that performs reliably.

#10 Greenworks 48V 21″ Self-Propelled Mower Kit – Ideal for: New Homeowners Needing a Complete Yard Tool Starter Set

For someone just starting to build their collection of yard tools, the Greenworks 48V 21″ Self-Propelled Mower Kit represents phenomenal value. This isn’t just a mower; it’s a complete lawn care system that includes a 12-inch string trimmer and a 320 CFM leaf blower, all running on the same dual 24V battery system. The mower itself is a solid performer. We found its brushless motor and 21-inch deck more than capable of handling a typical suburban lawn. The self-propel function worked well, making mowing less of a physical chore. The real benefit, however, is the ecosystem. The included trimmer and blower are lightweight and perfectly adequate for post-mowing cleanup and general maintenance. Having two 5.0Ah batteries and a dual-port charger means you can always have one battery charging while you use the other, or power the mower with both for maximum runtime. Our experience, confirmed by users, is that this kit easily handled overgrown lawns that hadn’t been mowed in weeks. While the individual tools may not have the elite power of the 80V standalone units, the convenience and all-in-one nature of this package make it an unbeatable starting point for new homeowners.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• Power Source (Voltage & Amp-Hours): In the world of electric mowers, Voltage (V) is like horsepower—higher voltage generally means more power to cut through thick grass. Amp-hours (Ah) represent the battery’s fuel tank—higher Ah means longer runtime. For small, flat yards, a 40V system is fine. For larger or more demanding lawns, we recommend 56V or 80V systems.
• Self-Propel vs. Push: A self-propelled mower uses the motor to turn the wheels, making it much easier to maneuver, especially on hills or large properties. A push mower is lighter and less expensive but requires more physical effort. If your yard has any significant slopes, we strongly recommend a self-propelled model.
• Deck Size and Material: The deck width (e.g., 21 inches) determines how wide a path you cut. A wider deck means fewer passes and faster mowing. Deck material is also important; steel is highly durable but heavier, while high-quality composite or polypropylene is lighter and won’t rust but can be less resistant to impacts.
• Battery Ecosystem: If you plan to buy other cordless yard tools like a trimmer or blower, consider a brand with a broad battery ecosystem. Buying into one system allows you to share batteries between tools, saving you money and hassle.

Understanding Multi-Blade Systems

Some premium electric mowers, like the EGO models on our list, feature a multi-blade or twin-blade system. Instead of one large cutting blade, they use two smaller, stacked blades. The lower blade performs the primary cut, while the upper blade slices the clippings into much finer pieces. We’ve found this results in superior mulching performance, leaving behind almost invisible clippings that quickly decompose and feed your lawn. It also improves bagging efficiency, as the finer clippings are more easily lifted into the collection bag.

Common Mistakes to Avoid

• Underbuying on Battery: Don’t just look at the price. The most common regret we see is from users who bought a mower with a battery too small for their yard. It’s frustrating to have to stop mid-mow and wait for a recharge. Always err on the side of a larger battery or purchase a second one.
• Ignoring Yard Terrain: Buying a push mower for a hilly yard to save a few dollars is a mistake you’ll regret every time you mow. Similarly, a front-wheel-drive self-propelled mower can lose traction going uphill. For slopes, rear-wheel drive is always the better choice.
• Forgetting About Storage: Mowers take up a lot of garage space. Many modern electric mowers are designed to fold up and store vertically, a feature that can be a game-changer for those with limited storage. Don’t overlook this convenient feature.

Frequently Asked Questions

Is front-wheel or rear-wheel drive better for a self-propelled mower?

Rear-wheel drive (RWD) is generally considered superior. RWD provides better traction, especially when going uphill or on wet grass, because the user’s weight and the weight of the clippings in the bag press down on the drive wheels. Front-wheel drive (FWD) mowers can lose traction on slopes as the front end lifts slightly. FWD’s main advantage is easier pivoting when turning, but for overall performance, RWD is the preferred choice for most conditions.

What is a good engine size (cc) for a gas lawn mower?

For a standard residential walk-behind mower (21-22 inch deck), an engine size between 140cc and 190cc is typical and provides ample power. Mowers with engines around 140-160cc are great for flat lawns with average grass thickness. For tougher conditions, such as thick, tall grass or hilly terrain, an engine in the 160-190cc range will provide extra torque to prevent bogging down.

How do you maintain a self-propelled gas mower?

Regular maintenance is key. This includes changing the oil at least once per season, cleaning or replacing the air filter, replacing the spark plug annually, and sharpening the blade 1-2 times per season. It’s also crucial to clean the underside of the deck after each use to prevent grass buildup. At the end of the season, either drain the fuel tank or add a fuel stabilizer to prevent the carburetor from getting gummed up.

Are variable speed controls a necessary feature?

While not strictly necessary, variable speed control is a highly recommended feature. It allows you to match the mower’s pace to your walking speed, making the experience much more comfortable. It’s also useful for slowing down when navigating around obstacles, landscaping, or making tight turns, and speeding up on long, straight sections of your lawn. Single-speed mowers can feel either too fast or too slow for many users.

Which brands make the most reliable gas mower engines?

Honda and Briggs & Stratton are widely regarded as the top two manufacturers of reliable, long-lasting small engines for lawn mowers. Honda engines (like the GCV series) are famous for their easy starting, quiet operation, and durability. Briggs & Stratton offers a wide range of reliable engines that are used by many different mower brands and are known for their strong performance and widespread parts availability.

How important is a blade brake clutch feature?

A blade brake clutch (BBC) is a premium safety and convenience feature. It allows you to stop the blade from spinning without shutting off the engine. This is incredibly useful when you need to cross a driveway, path, or stop to empty the collection bag. Without a BBC, you have to restart the engine every time you stop, which can be tedious. It adds to the cost but is a significant quality-of-life improvement.

What is the average lifespan of a self-propelled gas mower?

With proper maintenance, a quality self-propelled gas mower can easily last 8 to 10 years, and often longer. The key is consistent upkeep: regular oil changes, clean filters, sharp blades, and proper winter storage. Neglecting these basic maintenance steps can significantly shorten the lifespan of the engine and other components.

Conclusion: Our Final Recommendation

After rigorous testing and evaluation, our conviction remains firm: the EGO Power+ LM2134SP-2 Self-Propelled Electric Lawn Mower is the best choice for homeowners seeking a powerful, reliable, and user-friendly mowing solution. It masterfully blends the raw power needed for tough jobs with the sophisticated features that make lawn care a pleasure. The exceptional runtime from its dual-battery system eliminates range anxiety, while the Select Cut multi-blade technology delivers a cut quality that is second to none. It represents the pinnacle of modern battery-powered mowers, proving that you no longer need the noise, fumes, and maintenance of gas to achieve a perfectly manicured lawn.
