7 Best Rototillers & Self-Propelled Lawn Mowers of 2025

Punchy and confident, the YARDMAX 22-inch brings a 201cc engine and a unique 6-speed CVT that syncs pace to your stride—no herky-jerky surges. Its rear-wheel drive with 8′ front/11′ rear rubber tires and aggressive spike tread grips flat, sloped, and uneven yards without spinning out. A 16-gauge, one-piece steel deck with MaxFlow airflow tech boosts mulching quality while the single-lever height control (1.38’–3.55′) solves the constant tweaking pain.

In testing across thick spring growth and damp patches, the YARDMAX’s torque kept blade speed steady, leaving a clean line with fewer double-passes. The 22-inch deck covers ground quickly, and the deck cleanout port makes hose-downs painless. It shines on mixed terrain thanks to RWD traction, though it’s heavier than cordless models and requires typical gas upkeep.

Compared with the Greenworks 40V, YARDMAX delivers stronger pull on hills and superior mulching in tall grass but trades away low-noise convenience. Versus the PowerSmart 150cc, it’s more refined in speed control and deck stability, ideal for homeowners who want traction, pace control, and durability in one. If you prioritize power and terrain confidence over ultra-light portability, this outmuscles the MightyMow options while offering more control than most gas peers.

Sprightly and quiet, the MightyMow 40V packs a brushless motor up to 3500 RPM and dual 8.0Ah batteries for up to 60 minutes self-propelled runtime. The 21-inch steel deck and boosted airflow deliver tidy bagging and effective mulching without the fumes or pull-cord drama. Variable pace from 2.0–4.3 ft/s makes hills less daunting and long pushes less tiring.

On weekly cuts, it glides through suburban lawns and handles light-to-moderate growth smoothly; the 3-in-1 system swaps from bagging to side-discharge in seconds. The single-lever height control (1’–3′) caters to shorter turf profiles, though it’s less ideal if you prefer taller summer heights. Wet or overgrown grass will drain runtime faster, but the included dual charger eases turnaround.

Against the Greenworks 40V, MightyMow trades a touch of endurance for a more generous battery kit and straightforward pace control. It’s also lighter-handling than gas units like the YARDMAX, suiting homeowners who want a cordless self-propelled mower that’s easy to store and maintain. If you’re weighing features and runtime, it undercuts the Greenworks on kit completeness while remaining competitive in real-world cuts.

Refined and efficient, the Greenworks 40V self-propelled mower balances brushless power with a durable 21-inch steel deck and up to 45 minutes of runtime on a 5.0Ah pack. Rear-wheel drive delivers better traction in tough patches than front-drive electrics, and the vertical storage design saves about 70% space—a real garage win. With a 7-position height adjust and 3-in-1 cutting, it targets tidy, repeatable lawns.

In real-world cuts, it excels at weekly maintenance on quarter-acre lots, handling moderate growth without bogging. The drivetrain feels planted on light slopes and uneven seams, and noise stays neighborhood-friendly. Runtime varies with grass density and self-propel speed; thick/wet grass can push the limits but cut finish stays impressively even.

Compared to the MightyMow 40V, Greenworks generally feels more refined and consistent under load, though the included battery offers slightly less total runtime on paper. It’s quieter and cleaner than the YARDMAX gas model, but won’t match gas torque in tall or wet grass. Ideal for homeowners prioritizing low maintenance, compact storage, and reliable cut quality, it offers a strong features-to-performance ratio versus the MightyMow 40V kit.

Built for grunt, the PowerSmart 21-inch uses a Briggs & Stratton 140cc engine and rear-wheel drive to bulldoze through thick, tall, or damp grass without bogging. The steel deck and 3-in-1 setup deliver flexible disposal, while the 10′ rear wheels keep traction on slopes and rough patches. A single-lever height adjust (1.5’–3.9′) makes seasonal shifts easy.

On overgrown test patches, the engine maintained blade speed, leaving fewer stragglers than lighter cordless units. The self-propel pull is confident without feeling jumpy, and the 21-inch deck reduces passes on mid-sized yards. Downsides: more vibration than premium gas models and typical gas maintenance cadence.

Versus the YARDMAX 201cc, this PowerSmart is slightly less feature-rich but still excellent for thick grass, delivering serious cut authority at a lighter footprint. Compared to Greenworks, it’s louder and higher maintenance but wins decisively in raw torque and tall growth recovery. Best for buyers who want reliable gas power to tame unruly lawns without stepping up to pro-grade gear.

Confident and fast, this PowerSmart pairs a 150cc Briggs & Stratton EX625 with a 22-inch deck to cover more lawn with fewer passes. The rear-wheel drive and time-saving blade design handle dense patches well, while the 3-in-1 system and 1.4-bushel bag reduce stops. A 6-position height range (1.5’–3.9′) accommodates seasonal shifts.

In back-to-back runs on large yards, the broader deck noticeably shortens mow times and its propulsion stays consistent on mild-to-moderate slopes. Mulching quality is strong for a midrange gas unit, and bag capacity is generous for clippings-heavy weeks. It can feel bulkier in tight landscaping and, like most gas models, needs routine maintenance.

Compared with the YARDMAX 201cc, you give up CVT finesse but gain a wider deck for faster coverage—ideal for large yards that value throughput. Against the 140cc PowerSmart, this model provides a bit more headroom in heavy growth and fewer re-cuts. For buyers prioritizing area coverage and dependable traction, it offers compelling performance-for-feature trade-offs.

Sure-footed and sturdy, the SENIX uses a 163cc Briggs & Stratton EXi675 and rear-wheel drive to attack slopes and thick turf with confidence. Its 22-inch deck, 3-in-1 cutting, and included 19-gallon bag emphasize efficiency, while oversized 8’/11′ wheels smooth out bumpy yards. The single-lever height control spans 1.25’–4′, offering one of the taller top settings here.

On hilly test sections, traction stayed predictable and the self-propel didn’t surge, making side-hill passes less stressful. The washout port simplifies cleanup, and the ergonomics reduce fatigue on longer sessions. It’s heavier than cordless options and takes space, but vertical-friendly storage helps.

Stacked against the PowerSmart 22-inch, the SENIX provides similar deck size with a slightly stronger engine feel on inclines and a taller max height for summer turf. Compared to YARDMAX, it lacks CVT polish but feels purpose-built for slope stability. For homeowners juggling uneven yards, this is a best-on-slopes pick that balances power, traction, and practicality.

Nimble and featherweight, the MightyMow 18-inch is a lightweight self-propelled cordless mower with a 4200 RPM brushless motor and dual 4.0Ah batteries for up to 30 minutes of runtime. The compact 18-inch deck and 40L bag make it easy to maneuver around landscaping and narrow gates. Pace control from 2.0–4.3 ft/s removes the push from push mowing.

In tight yards, it dances around beds and fences, and the single-lever height adjust (1’–3′) supports neat, low-to-medium cuts. It’s best for frequent trims on small lawns; thick or wet grass will sap runtime and may require a slower pace. Noise and maintenance are minimal, ideal for early-morning or HOA-sensitive areas.

Compared to the MightyMow 40V 21-inch, this model trades runtime and coverage for lightweight handling and smaller storage needs. Against gas units like PowerSmart or YARDMAX, it can’t match torque, but it excels where portability and easy control matter. Perfect for homeowners who want a small, maneuverable self-propelled mower without gas hassles.
