9 Best Self Propelled Lawn Mowers to Buy in 2025

Powerhouse convenience meets quiet confidence in the Greenworks 40V 21-inch. Its brushless motor and durable 21-inch steel deck deliver strong torque with smooth, low-vibration operation, while the rear-wheel drive self-propel system bites into slopes better than front-drive electrics. The 3-in-1 cut system (bag, mulch, side discharge) and 7-position height adjust give you flexibility across seasons. For first-time cordless buyers, the maintenance-free design solves the gas mess and hard starts.

In testing, the included 5.0Ah 40V pack gave around 30–45 minutes depending on grass thickness and self-propel usage—enough for many suburban yards. The 21-inch deck reduces passes, and the vertical storage feature genuinely saves garage space. It tracks well over uneven ground thanks to RWD, though wet, very tall grass can slow blade speed and reduce mulching quality.

Against the MightyMow 2x20V 18-inch, Greenworks wins on deck size, traction, and storage efficiency; MightyMow is lighter but requires more passes. Step up to the EGO LM2200SP and you get more torque and a lifetime aluminum deck at the cost of a separate battery purchase and higher heft. The Greenworks fits homeowners wanting a balanced, low-maintenance self-propelled mower with solid runtime—offering more capability per charge than the budget MightyMow 18-inch.

Zippy and approachable, the MightyMow 2x20V 18-inch focuses on lightweight maneuverability and variable self-propel speed for small yards. The brushless motor up to 4200 RPM keeps blade tip speed lively, while the 18-inch deck is easy to steer around beds and gates. Its 2.0–4.3 ft/s pace range helps match your stride, easing hills without overpulling.

In use, the dual 4.0Ah packs yield around 25–30 minutes with propulsion engaged—perfect for quick trims or townhome lawns. The 40L bag fills fast on spring growth, so mulching is handy to cut stops. It handles typical weekly growth well; heavy, damp grass will tax runtime and may require a slower pace or a second pass to keep clumping down.

Compared with the Greenworks 21-inch, MightyMow is more compact and nimble but needs more passes and has noticeably shorter runtime. Step up to MightyMow’s 40V 21-inch for longer mowing sessions and a broader cut, albeit with more weight. For budget-focused buyers with small plots, this is the most approachable self-propelled entry in the lineup, trading deck width for simplicity.

The EGO LM2200SP is a muscle-class cordless mower with gas-beating performance. Its Select Cut multi-blade system and up to 11.1 ft-lbs of torque pair with a 22-inch cast aluminum deck for durable, high-lift bagging and fine mulching. Touch Drive puts speed control under your palm, delivering intuitive self-propel engagement and precision throttle.

Real-world, the recommended 56V 10Ah pack (not included) pushes up to about 70 minutes in average conditions; heavy growth narrows that window but rarely bogs the blades thanks to the 3,350 RPM ceiling. The wide deck eats acreage, and aluminum resists corrosion and dents better than stamped steel. Weight is higher than smaller electrics; tight turns need a bit more planning.

Against the Greenworks 40V, EGO adds cut quality, deck longevity, and raw torque, countered by higher tool cost and separate battery purchase. Versus MightyMow 40V 21-inch, EGO is the performance and durability pick for larger lawns or thick northern grasses. If you want premium cordless power with class-leading cut versatility, this is the standout, offering more performance headroom than Greenworks.

The YARDMAX 22-inch is a workhorse gas mower built for varied terrain and thick lawns. Its 201cc engine with RWD and CVT 6-speed control matches your stride and boosts traction on slopes and bumpy yards. A 16-gauge stamped steel deck and MaxFlow volute design improve airflow for mulching and bagging.

On turf, it muscles through tall, damp grass where many cordless models stall, and the deck cleanout port simplifies post-mow maintenance. The 7-position height range (1.38–3.55 inches) suits seasonal shifts, while 8-inch front and 11-inch rear wheels roll smoothly over ruts. Noise and emissions are the trade-offs, and the unit is heavier than battery models.

Compared with the BILT HARD 201cc, YARDMAX offers finer speed control via CVT and superior traction tread, while BILT HARD answers with a broader 1.2–3.75-inch height range. Versus PowerSmart’s 140cc, YARDMAX packs more torque for dense grass. Ideal for homeowners battling mixed terrain and overgrown patches, it balances control, power, and cut quality better than lighter gas peers.

The BILT HARD 21-inch is a torque-forward gas mower tailored for thick, fast-growing lawns. Its 201cc OHV engine (9.0 ft-lb torque) and rear-wheel drive give it the grunt to keep blade speed up in heavy loads. You get 3-in-1 versatility and an 8-position single-lever height adjustment from 1.2 to 3.75 inches, with an easy-start design that skips priming and choking.

In practice, it rolls confidently across large areas thanks to single-speed self-propel and a comfortable, foam-wrapped handle that reduces hand fatigue over longer sessions. The 21-inch steel deck balances speed and agility, and mulching performance is strong on weekly growth. Single-speed means you can’t fine-tune pace on slopes; traction is good, though not as aggressive as spiked treads.

Versus the YARDMAX, BILT HARD trades CVT flexibility for a simpler, punchy powertrain and a slightly wider height range. Compared to PowerSmart’s 140cc, the extra displacement is noticeable when tackling wet or overgrown sections. For users prioritizing raw power and straightforward operation, it’s a compelling choice for thick grass.

Built for endurance, the MightyMow 40V 21-inch delivers up to 60 minutes self-propelled (75 minutes push) from twin 8.0Ah packs—excellent for larger suburban lots. The brushless motor up to 3500 RPM and 21-inch steel deck offer efficient clipping lift and solid mulching, with a 3-in-1 system that easily swaps between bag, mulch, and side discharge. Variable self-propel from 2.0–4.3 ft/s keeps pacing comfortable on hills.

In real-world mowing, it maintains blade speed well through typical weekly growth; slowing the drive a touch preserves cut quality in thicker patches. The boosted return airflow helps fill bags evenly, reducing chute clogs. It’s heavier than 18-inch competitors but still easier to manage than most gas models.

Against the Greenworks 40V, MightyMow 40V wins on runtime with the included larger batteries, while Greenworks counters with vertical storage and slightly stronger traction feel. Compared with the MightyMow 18-inch, this is the productivity pick for bigger yards. If you want long runtime without gas, this model hits the sweet spot better than budget cordless options.

The SENIX LSSG-H2 is a versatile 22-inch gas mower that prioritizes ease-of-use and yard coverage. The 163cc Briggs & Stratton EXi675 delivers reliable starts with Prime n Pull and steady power for small to medium lawns. Rear-wheel drive with variable speed improves traction, while the 3-in-1 steel deck and included large bagger add flexibility.

On grass, it transitions cleanly from mulch to bagging, and the single-lever 6-position height adjust (1.25–4 inches) gives generous cut height for summer stress. The washout port helps keep airflow pathways clear, maintaining cut quality across the season. It’s less torquey than 200cc-class engines; dense, wet patches may need a slower pace.

Relative to the YARDMAX, SENIX offers more user-friendly starting and a higher maximum cut height, but less grunt for heavy growth. Compared to PowerSmart, you get a wider deck and variable speed RWD for better control on mixed terrain. For owners wanting a no-fuss, space-saving gas mower with reliable components, it’s a smart fit for typical suburban yards.

The PowerSmart 21-inch targets slope performance with rear-wheel drive and 10-inch rear wheels for surefooted traction. Its 140cc Briggs & Stratton engine is modest but reliable, pairing with a 21-inch steel deck and 3-in-1 cut options for versatile care. The single-lever 6-position height adjust (1.5–3.9 inches) simplifies seasonal changes.

In testing on inclines, the larger rear wheels help maintain line control and reduce spin, especially on damp morning cuts. It handles weekly growth well; very tall or wet grass may require a slower pace to avoid clumping due to the smaller displacement. The drive system is smooth, making it easier to track straight on uneven surfaces.

Versus YARDMAX’s 201cc, PowerSmart is lighter and more maneuverable but lacks the same thick-grass torque. Compared to SENIX, it cedes deck width but feels steadier on slopes thanks to wheel geometry. For homeowners with hilly yards who don’t regularly tackle overgrown turf, it’s a balanced, confidence-inspiring choice.

This 18.5-inch cordless stands out with the world’s first one-touch electric height adjustment—no bending, no levers, just tap to switch among six settings. The Easysurge technology ramps a 4100 RPM brushless motor for punchy blade speed, and the variable self-propel from 1.3–2.9 MPH makes tight control easy in smaller yards. The compact deck slips through gates and around landscaping with less hassle.

In real use, expect up to about 30 minutes per charge on typical grass, aligning with small-lot needs. The T-shaped, single-rod handle streamlines bag swaps and fold-down storage, genuinely reducing fiddling. It handles weekly growth crisply; sustained heavy, wet mowing will cut runtime and may need a second pass to keep clumps at bay.

Compared with the MightyMow 18-inch, this model’s electric height adjust is a real convenience upgrade, though MightyMow offers a slightly broader pace range. Stack it against Greenworks 21-inch and you trade runtime and deck width for superior ergonomics and precision height control. Ideal for users seeking ease-of-use and compact agility over raw coverage.
