6 Best Mulching Lawn Mowers to Buy in 2025

Silent power, surgical precision, and game-changing control define the EGO POWER+ LM2134SP-2. This self-propelled cordless mower redefines electric performance with its brushless motor, Touch Drive technology, and dual 56V 6.0Ah batteries delivering up to 100 minutes of runtime—enough to tackle lawns up to a full acre. The 21-inch steel deck and Select Cut multi-blade system ensure clean, consistent mulching, while the 8-position height adjustment lets you tailor cuts down to the quarter-inch, solving the age-old problem of uneven clippings and patchy lawn recovery.

In real-world testing across mixed grass types—from thick St. Augustine to fine fescue—the EGO mulched with exceptional finesse, recycling clippings into near-invisible particles that decomposed rapidly. The variable speed self-propel (0.9–3.1 MPH) adapts intuitively to your stride, reducing fatigue on long mowing sessions. The LED headlights are a surprising but welcome perk for early-morning or late-evening mowing. However, the heavier deck and rear-wheel drive make tight turns in tight spaces slightly cumbersome, and wet grass tends to cling, requiring a quick rinse via the deck wash port.

When stacked against gas-powered rivals like the BILT HARD 21-inch or PowerSmart models, the EGO trades raw engine roar for whisper-quiet efficiency—a win for noise-sensitive neighborhoods. It outclasses budget electrics like the Greenworks 16″ in cutting width, runtime, and mulching refinement, though it demands a premium investment. For homeowners seeking best-in-class mulching precision, zero emissions, and no pull-starts, this is the pinnacle of cordless innovation—offering smarter control and longer runtime than most gas mowers in its class.

Effortless, eco-friendly, and engineered for simplicity—the Greenworks 16″ mower is a breath of fresh air for small-yard owners tired of gas gunk and cord hassles. Weighing in at just 35 lbs, it’s 35% lighter than most competitors, making it a dream for seniors, apartment complexes, or anyone dreading the seasonal mower drag out of storage. The 40V 4.0Ah battery delivers 45 minutes of runtime, easily clearing ½-acre lawns on a single charge, and the push-button start eliminates pull-cord frustration. Its 2-in-1 mulching and bagging system handles routine clippings cleanly, though it’s not built for thick, overgrown grass.

During testing, the single-lever 5-position height adjustment (1.25″–3.375″) made quick work of seasonal changes, and the ultra-quiet operation (<75dB) meant no noise complaints from neighbors. On flat, well-maintained lawns, it mulched efficiently, with clippings breaking down evenly. But on damp mornings or with longer grass, the 16-inch deck showed its limits—multiple passes were needed, and the smaller battery struggled with dense patches. It’s not self-propelled, so your arms do the work, which can become tiring on larger or uneven terrain.

Compared to the EGO LM2134SP-2, this Greenworks model sacrifices cutting width, power, and self-propulsion for affordability and featherlight handling. Against gas mowers like the PowerSmart B0CYZYMTRG, it wins on maintenance-free operation and instant starts, but loses in raw cutting authority. For small, flat yards under ½ acre and users prioritizing ease of use, storage, and ecosystem compatibility, this is the smart entry point into cordless mowing—delivering clean mulching and quiet performance at a fraction of the cost of high-end models.

Raw power meets rugged reliability in the BILT HARD 21-inch gas mower—a workhorse built for mid-sized lawns that demand consistent performance without breaking the bank. Its 201cc 4-cycle OHV engine cranks out 9.0 ft·lb of torque, slicing through thick grass with gas-powered authority that budget electrics simply can’t match. The 3-in-1 steel deck (mulch, bag, side-discharge) and 21-inch cutting width make it a time-saver, while the single-lever 8-position height adjustment (1.2″–3.75″) ensures precise lawn customization. No-choke, no-primer starts mean reliable ignition every time, solving one of the biggest pain points of gas mowers.

In field tests, the rear-wheel self-propel made mowing long, flat stretches feel effortless, though the single-speed drive lacked the fine-tuned control of variable-speed models like the EGO. Mulching performance was solid but not elite—clippings were moderately fine, but a second pass improved results. On damp grass or slopes, tread grip was adequate, but the foam-wrapped handle kept hand fatigue low over extended sessions. The steel deck showed minor vibration, but overall build quality felt durable for the price.

Against the Greenworks 16″, this BILT HARD model dominates in power and coverage, while undercutting the YARDMAX and EGO on cost. It doesn’t offer the CVT speed control of the YARDMAX or the zero emissions of electric models, but it’s a no-nonsense, dependable performer for homeowners who want gas-powered reliability without premium pricing. For yards up to ¾ acre with mixed conditions, it strikes a sweet balance of power, features, and value—offering stronger mulching and wider cuts than entry-level electrics, though with more noise and maintenance.

Engineered for endurance and efficiency, the PowerSmart B0F29HN7PY is a no-frills powerhouse designed for medium to large yards where runtime and reliability trump bells and whistles. Powered by a 140cc Briggs & Stratton engine, known for smooth starts and long life, this mower delivers consistent performance even in hot, humid conditions. The 21-inch steel deck covers ground quickly, and the 3-in-1 functionality (bagging, mulching, rear discharge) gives flexibility for different lawn needs. Its self-propelled rear-wheel drive and 10-inch rear wheels provide strong traction on uneven terrain, making it a standout for larger, sloped properties.

In real-world use, the 6-position height adjustment (1.5″–3.9″) was quick and reliable, though not as finely graded as 8-position models. Mulching was effective under dry conditions, but clippings were coarser than high-end models, benefiting from a second pass. The 1.4-bushel bag filled quickly in leafy lawns, requiring frequent emptying. On wet or thick grass, the engine held strong, but the plastic lever housing felt less durable than metal counterparts. Still, for a sub-$300 mower, it’s impressively capable.

Compared to the BILT HARD 201cc model, this PowerSmart trades engine power for proven B&S reliability and a lower price point. Against the EGO electric, it lacks quiet operation and zero emissions, but wins in run time and refuel speed—ideal for users who hate battery anxiety. For homeowners with large, challenging yards who want dependable gas power and solid mulching, this is a smart, budget-conscious choice—offering wider cuts and better traction than smaller mowers, though with less refined mulching than premium models.

Focused, efficient, and purpose-built for mulching mastery, the PowerSmart B0CYZYMTRG is the best-in-class for homeowners who prioritize grass recycling over bagging or discharge. Its 144cc OHV engine with auto-choke ensures effortless starts every time, eliminating the frustration of cold-engine tugs. The 21-inch heavy-duty blade and 2-in-1 steel deck are tuned specifically for optimal mulching performance, generating a strong airflow that chops clippings into fine particles that vanish into the turf. The 6-position dual-lever height adjustment (1.5″–3.9″) offers precise control, and the high rear wheels (10″) make pushing over uneven ground smooth and stable.

In testing, this mower excelled in dry, medium-length grass, producing some of the finest mulch in its price range—rivaling models twice its cost. The compact foldable design saves 70% storage space, a major win for garages or sheds with tight quarters. However, the lack of bagging limits versatility, and side discharge can be uneven on tall grass. Without self-propel, it demands more physical effort, especially on slopes. It’s not for large, complex yards, but for routine maintenance on flat to rolling terrain, it’s incredibly effective.

Against the YARDMAX with CVT, it loses on slope handling and speed control, but wins on simplicity and focused mulching design. Compared to the EGO, it lacks electric convenience, but offers longer runtime and lower upfront cost. For users who mow weekly and want premium mulching without frills, this is the most dedicated tool in the lineup—delivering superior airflow and cutting precision for healthier lawns, though without self-propel or bagging flexibility.

Unmatched control on slopes and uneven terrain—the YARDMAX B0B136QPNL is a terrain-taming beast built for challenging yards where stability and speed matter. Its industry-leading CVT (Continuously Variable Transmission) with 6-speed select lever lets you match mowing pace to your walk, eliminating jerky starts and stops. The 22-inch heavy-duty deck and 201cc engine deliver broad, powerful cuts, while MaxFlow deck technology enhances airflow for superior mulching—a rare combo in this class. Combine that with aggressive spike-tread tires and 11-inch rear wheels, and you’ve got a mower that climbs hills with confidence.

On real sloped lawns, the CVT and rear-wheel drive made mowing feel effortless and precise, with no loss of traction even on damp, grassy inclines. The 7 cutting heights (1.38″–3.55″) and single-lever adjustment made changes quick, and the 16-gauge steel deck felt rock-solid, with minimal vibration. Mulching was excellent, thanks to the volute spiral deck design that recirculates clippings for finer cuts. However, the larger size makes storage trickier, and the fold mechanism, while space-saving, isn’t as compact as claimed.

Versus the PowerSmart B0F29HN7PY, the YARDMAX offers superior speed control and traction, justifying its higher price. Against the BILT HARD, it wins on slope handling and deck tech, though both share similar engines. For homeowners with ** The YARDMAX delivers smoother control and better mulching than most rivals, making it worth the investment for tough terrain**.
