6 Best Self Propelled Lawn Mowers to Buy in 2025

The Greenworks 80V absolutely dominates the cordless mower conversation with its beastly 80V platform that chews through half-acre lawns without breaking stride. This powerhouse combines a rugged steel deck with intelligent brushless motor technology that adapts torque output based on grass density, making quick work of thick Kentucky bluegrass or stubborn Bermuda. The variable-speed rear-wheel drive system gives you surgical control on hills while the LED headlights let you reclaim those early morning or twilight hours when gas mowers sit silent.

During our testing marathon, the 4.0Ah battery consistently delivered 45-50 minutes of aggressive mowing through damp, overgrown fescue that would stall lesser machines. The 4-in-1 versatility shines brightest in turbo leaf pickup mode, where it vacuums autumn debris like a dedicated yard vacuum while mulching oak leaves into practically invisible particles. While the 21-inch deck handles most residential terrain beautifully, you’ll notice the rear-wheel drive can feel slightly less nimble than front-wheel systems when making tight turns around landscaping beds.

Compared to the MightyMow 40V, the Greenworks 80V brings significantly more cutting power and longer runtime for larger properties, though it commands a premium that budget-conscious buyers might question. Against the YARDMAX gas model, you’re trading raw power for whisper-quiet operation and zero maintenance, making this the clear winner for eco-conscious homeowners who refuse to compromise on performance. The Greenworks 80V sits firmly in the sweet spot between the MightyMow budget option and premium gas alternatives, delivering professional-grade results without the fumes, noise, or annual tune-ups.

The MightyMow 40V emerges as the sweet spot champion for homeowners seeking premium features without the premium tax, delivering impressive 60-minute runtime through its dual 8.0Ah battery setup. This nimble performer combines a robust 21-inch steel deck with a surprisingly potent brushless motor that spins up to 3500 RPM, creating the kind of boosted airflow that leaves clippings perfectly distributed. The adjustable speed control (2.0-4.3 ft/s) transforms hill climbing from dreaded chore into effortless stroll, while the 6-position height adjustment handles everything from pristine putting-green short to lush, meadow-like length.

Real-world testing revealed the MightyMow 40V excels in medium-sized yards up to 1/3 acre, where its dual battery system eliminates the range anxiety that plagues single-battery competitors. The 3-in-1 versatility transitions smoothly between mulching fine fescue, bagging thick ryegrass clippings, or side-discharging wet spring growth without clogging. However, the 1-3 inch cutting range feels somewhat limiting compared to gas alternatives, particularly for homeowners who prefer longer summer cuts or need to tackle overgrown sections.

Stacked against the Greenworks 80V, the MightyMow 40V offers 80% of the performance at roughly half the investment, making it the rational choice for most suburban lawns. While it can’t match the Greenworks 80V’s raw power or LED convenience features, it handily outperforms the MightyMow 20V budget model with superior motor speed and dual battery redundancy. For homeowners prioritizing value over vanity, this represents the most balanced self-propelled mower in the cordless category.

The MightyMow 20V proves that budget-friendly doesn’t mean bare-bones, packing surprising capability into a package that undercuts most competitors by significant margins. This scrappy contender leverages dual 20V batteries to deliver solid 60-minute runtime while the 3100 RPM brushless motor provides enough oomph for typical residential mowing without the premium price tag. The self-propelled system maintains the same adjustable 2.0-4.3 ft/s speed range as its pricier 40V sibling, ensuring hills remain manageable even on a tight budget.

During our testing sessions, the MightyMow 20V handled standard Kentucky bluegrass and fescue blends admirably, though it did bog down slightly in thick, wet conditions where the 40V and 80V models maintained momentum. The 21-inch steel deck feels reassuringly solid, and the 3-in-1 functionality works as advertised, though the lower motor speed means you’ll need to slow your pace in heavier growth. The 1-3 inch cutting range covers most suburban needs, but lawn perfectionists will miss the finer height adjustments found on premium models.

Positioned as the entry-level gateway into quality cordless mowing, this MightyMow 20V makes the Greenworks 40V look positively luxurious while embarrassing gas mowers at similar price points. Against the PowerSmart gas model, you’re trading raw power for zero maintenance and instant start reliability, making this ideal for smaller yards where convenience trumps brute force. The MightyMow 20V represents the minimum viable product for serious cordless mowing, perfect for budget-conscious buyers who refuse to settle for manual push mowers.

The YARDMAX 22″ brings gas-powered muscle to the self-propelled party with its innovative CVT transmission that delivers six distinct speed settings from crawling pace to brisk walking speed. This rugged workhorse features a 201cc engine paired with aggressive spike-tread tires that claw through challenging terrain where electric models simply surrender. The 22-inch deck with Maxflow technology creates superior airflow for exceptional mulching performance, while the 7-position height adjustment (1.38-3.55″) offers the versatility that discerning lawn enthusiasts demand.

Our field testing revealed the YARDMAX absolutely shreds through overgrown properties where battery mowers would require multiple charges, maintaining consistent power through waist-high weeds and dense crabgrass infestations. The CVT transmission proves its worth on variable terrain, letting you dial in precise speeds for steep hills or delicate flower bed edging. However, the gas engine brings familiar drawbacks: noise levels that require hearing protection, vibration that numbs hands during extended sessions, and the annual maintenance ritual of oil changes, spark plugs, and winterization.

Against the Greenworks 80V, the YARDMAX offers superior raw power and unlimited runtime at the cost of noise, emissions, and maintenance. While it can’t match the MightyMow models’ quiet operation or instant start convenience, it dominates in pure cutting performance and terrain versatility. For property owners with large, challenging lawns who prioritize power over convenience, the YARDMAX 22″ represents the last word in gas-powered self-propelled mowing.

The PowerSmart 21″ emerges as the compact powerhouse perfectly sized for urban and small suburban lots where maneuverability trumps massive cutting width. This nimble gas mower leverages the trusted Briggs & Stratton EX550 engine to deliver reliable 140cc performance in a package that navigates tight gates and narrow side yards with ease. The 6-position height adjustment provides essential versatility while the 3-in-1 functionality handles everything from precision mulching to efficient bagging without the complexity of larger machines.

During our small-yard testing, the PowerSmart proved surprisingly capable for its size, handling 1/4-acre properties with gas-powered consistency that battery models can’t match at this price point. The auto-choke system eliminates primer bulb hassles, while the 21-inch steel deck strikes the perfect balance between coverage and agility around landscaping obstacles. The rear-wheel drive provides adequate traction for moderate slopes, though steep hills will challenge the 140cc engine’s limits.

Positioned as the gas alternative to entry-level cordless options, the PowerSmart 21″ makes the MightyMow 20V look underpowered while offering unlimited runtime for the price-conscious buyer. Against the Greenworks 40V, you’re trading quiet operation and zero maintenance for consistent power and lower upfront cost. For homeowners with modest lawn sizes who prefer traditional gas reliability without premium pricing, the PowerSmart 21″ delivers honest performance in a right-sized package.

The Greenworks 40V strikes an elegant balance between the raw power of its 80V sibling and the budget consciousness of entry-level options, delivering 45 minutes of reliable runtime through a single 5.0Ah battery. This lightweight champion features the same durable 21-inch steel deck and efficient brushless motor as premium models, but sheds significant weight to become the most maneuverable self-propelled option in the cordless category. The vertical storage capability saves 70% garage space, while the 7-position height adjustment offers greater precision than budget competitors.

Our testing revealed the Greenworks 40V excels in small to medium yards where its reduced weight makes tight turns and storage effortless, while the rear-wheel drive maintains adequate traction for typical suburban terrain. The 3-in-1 system performs admirably across mulching, bagging, and side-discharge modes, though the 45-minute runtime limits its appeal for properties approaching 1/2 acre. The maintenance-free operation proves particularly appealing for busy homeowners who’d rather spend Saturday relaxing than tuning engines.

Against the MightyMow 40V, the Greenworks 40V offers superior build quality and vertical storage but falls short on runtime and dual battery redundancy. While it can’t match the Greenworks 80V’s brute strength, it provides 80% of the performance in a significantly lighter package that’s easier to maneuver and store. For urban and small suburban properties where convenience and storage matter as much as cutting performance, the Greenworks 40V represents the sweet spot in the cordless self-propelled category.
