6 Best 3-in-1 Self Propelled Lawn Mowers of 2025

This cordless powerhouse redefines what it means to mow without gas—delivering brushless torque, self-propelled intelligence, and exceptional runtime in one sleek package. The 80V system paired with a 21″ steel deck slices through thick grass with authority, while the rear-wheel drive and variable speed control make pushing feel like gliding. With LED headlights and a 4-in-1 cutting system (mulch, bag, side discharge, and turbo leaf pickup), it’s built for homeowners who demand versatility and precision without the noise or fumes.

In real-world testing, the mower consistently handled half-acre lawns on a single charge, though dense, wet grass reduced runtime slightly—expected for any cordless model. The brushless motor not only boosts efficiency but also extends lifespan, running 3x quieter than traditional gas mowers. It excels on flat to gently sloped terrain, but steeper inclines require careful pacing to maintain traction. While the rapid charger helps, waiting between cuts on larger properties can be a minor bottleneck—especially if you don’t have a spare battery.

Compared to the MightyMow 40V and PowerSmart gas models, this Greenworks unit strikes a premium balance: more power and runtime than most cordless competitors, yet cleaner and easier to maintain than gas alternatives. It’s ideal for eco-conscious homeowners with medium to large yards who value low maintenance, instant starts, and multi-functionality. Against similarly equipped gas mowers, it trades some raw power for near-silent operation and zero emissions—offering better long-term value for those willing to invest upfront.

When battery life and consistent self-propelled performance top your priority list, this MightyMow 40V model delivers with quiet confidence. Packing two 8.0Ah batteries, it offers up to 75 minutes of mowing without self-propel engaged—enough to tackle larger yards that typically challenge cordless mowers. The brushless motor spins at 3500 RPM, generating strong airflow for efficient clipping collection, while the rear-wheel self-propel system lets you walk at your own pace, from a leisurely 2.0 ft/s to a brisk 4.3 ft/s.

Field tests show it performs exceptionally well on flat to moderately sloped lawns, maintaining momentum even in taller grass thanks to its boosted return airflow design. The 21″ steel deck cuts cleanly across all height settings (1″–3″), and switching between mulch, bag, and side discharge is tool-free and intuitive. However, when grass is overly wet or overgrown, the motor occasionally bogs down—recovering quickly but reminding you this isn’t a commercial-grade machine. On very hilly terrain, sustained climbs drain power faster, nudging the limits of its otherwise impressive runtime.

Versus the Greenworks 80V, it trades voltage for battery redundancy—offering longer total runtime at a lower cost, though with less peak power. Compared to gas models like YARDMAX or PowerSmart, it wins on noise and maintenance but lacks the relentless stamina needed for acre-plus properties. It’s a sweet spot for suburban homeowners with 1/3 to 1/2 acre lots who want long runtime, minimal upkeep, and push-free mowing. For the features offered, it provides better battery value than pricier cordless options.

For those who need uninterrupted power and all-terrain reliability, the PowerSmart 21-inch gas mower stands as a rugged workhorse powered by a 140cc Briggs & Stratton engine—a name synonymous with durability in small engines. The rear-wheel drive system and 10-inch rear tires deliver confident traction on uneven or sloped lawns, while the 21″ steel deck ensures wide, efficient passes that cut mowing time significantly. With 3-in-1 functionality and a single-lever height adjustment (1.5″–3.9″), it adapts quickly to changing conditions, making it a go-to for users who prioritize performance over convenience.

In testing, it started reliably with minimal pull effort, thanks to the B&S engine’s consistent ignition system, and powered through thick, dry grass without hesitation. The rear discharge mode is particularly effective for clearing overgrown patches, and the 1.4-bushel bag fills evenly with minimal clogging. However, it’s noticeably louder than electric models, and the engine requires seasonal maintenance like oil changes and fuel stabilization—drawbacks for users seeking a plug-and-play experience. On soft, damp ground, the rear wheels occasionally lose grip, especially when turning.

Stacked against the Greenworks and MightyMow cordless models, this PowerSmart unit doesn’t need recharging and runs as long as you have gas—a major advantage for large or irregularly shaped yards. Compared to the AMERISUN budget model, it offers a more refined drive system and smoother operation. It’s best suited for homeowners with medium to large lawns who face varied terrain and demand gas-powered resilience. While heavier and noisier, it outperforms electric alternatives in sheer endurance and hill-climbing ability.

Don’t let the compact 18-inch deck fool you—this MightyMow cordless model is engineered for agile, effortless mowing in tight spaces where larger mowers struggle. Powered by two 20V 4.0Ah batteries, it delivers up to 30 minutes of runtime with self-propel active, making it ideal for small to medium yards under 1/3 acre. The brushless motor hits an impressive 4200 RPM, offering sharp, clean cuts and strong suction into the 40L grass bag—even in dry, brittle grass that tends to scatter.

In real use, the mower shines on narrow lawns, around flower beds, and in yards with gates or tight storage areas. The self-propelled rear wheels adjust to walking speeds between 2.0 and 4.3 ft/s, removing the strain of manual pushing without sacrificing control. The 6-position height adjustment (1″–3″) is smooth and accessible, and switching between mulch, bag, and side discharge is quick. However, the smaller deck means more passes for wider lawns, and the runtime limits its use on properties over a quarter acre—especially if grass is tall or dense.

Compared to the 21-inch MightyMow 40V, it sacrifices cutting width and total runtime for superior maneuverability and storage ease. Against gas models like AMERISUN or PowerSmart, it wins on noise and startup simplicity but can’t match their continuous runtime. It’s the perfect fit for urban or suburban homeowners with compact yards who value lightweight handling, zero emissions, and quiet operation. For its size class, it offers better speed control and motor efficiency than similarly priced cordless mowers.

If speed precision and terrain adaptability are your top concerns, the YARDMAX 22-inch mower sets a new benchmark with its industry-leading CVT transmission—a rare feature that allows infinitely variable speed control via a 6-speed shift lever. This isn’t just self-propelled; it’s intelligently responsive, letting you match your walking pace exactly, whether strolling on flat ground or powering up a steep slope. The 22-inch heavy-duty steel deck and MaxFlow deck technology ensure superior airflow for cleaner cuts and better mulching performance.

In performance trials, the 201cc OHV engine delivered strong, vibration-free power, easily handling thick grass and uneven terrain. The 11-inch rear wheels and spike-tread tires provided excellent grip, even on damp, sloped lawns, while the double ball bearing wheels rolled smoothly over bumps. The 7 height settings (1.38″–3.55″) offer fine-tuned control, and the deck cleanout port makes post-mow cleanup simple. However, the mower’s weight and size make it less ideal for tight spaces or users with limited storage.

Against the PowerSmart and AMERISUN gas models, the YARDMAX stands out with its CVT transmission and larger cutting width, offering more control and efficiency. While priced higher, it justifies the cost with professional-grade components like the seamless 16-gauge steel deck and foldable design for storage. It’s best for serious homeowners with large, challenging yards who want commercial-like performance in a residential package. Compared to other gas mowers, it delivers superior speed modulation and build quality for the investment.

For budget-conscious buyers who still want gas-powered performance, the AMERISUN 21-inch mower delivers solid reliability without the premium price tag. Its 144cc OHV 4-stroke engine features auto choke, ensuring easy starts with minimal effort—no priming or choke adjustments needed. The 21-inch steel deck cuts wide and even, reducing passes across the lawn, while the 3-in-1 system (bag, mulch, side discharge) offers full versatility for year-round lawn care.

In real-world use, it handled typical suburban lawns with ease, maintaining consistent power through dry and moderately thick grass. The single-lever height adjustment (1.5″–3.9″) is intuitive and durable, and the 1.4-bushel grass catcher fills evenly with minimal spillage. The 10-inch rear wheels with dual ball bearings roll smoothly over uneven ground, making it a strong performer on bumpy or sloped terrain. However, like most entry-level gas mowers, it’s louder than premium models and lacks advanced features like cruise control or CVT.

When compared to the YARDMAX and PowerSmart, it sacrifices some refinement and transmission tech but delivers core gas-powered functionality at a fraction of the cost. It’s an excellent choice for first-time homeowners or rental properties where durability and affordability matter most. Against similarly priced electric models, it offers unlimited runtime and better hill performance—making it the most capable budget gas mower in the lineup. It doesn’t dazzle, but it gets the job done—dependably.
