6 Best Lawn Mowers for Mulching Leaves of 2025

This Greenworks 40V 21″ self-propelled mower redefines what cordless can achieve, especially when mulching leaves in fall. With a brushless motor, it delivers consistent torque even under heavy leaf loads, avoiding the stalling common in lower-end electric models. The 21-inch steel deck combined with a 3-in-1 design makes it a mulching powerhouse, finely chopping leaves and grass into nutrient-rich mulch that disappears back into your lawn—no clumping, no clogging. If you’re tired of noisy gas mowers or underpowered push models, this one solves the core frustration of inefficient mulching and yard cleanup.

In real-world testing across mixed grass and dense leaf cover, the mower handled wet oak leaves with surprising ease, thanks to the high blade speed and optimized airflow under the deck. The 5.0Ah battery reliably powered through up to ¾ acre on a single charge, especially when using the mulch mode which reduces strain compared to bagging. Rear-wheel drive and self-propelled functionality make it a dream on uneven terrain, though thick, matted leaves can occasionally slow blade speed—requiring a second pass. At just under 75dB, it’s whisper-quiet, letting you mow early without disturbing the neighborhood.

Compared to gas-powered rivals like the PowerSmart B&S model, this Greenworks trades raw engine durability for cleaner operation, instant starts, and zero maintenance—a major win for eco-conscious homeowners. While it may not match the brute force of a 140cc engine on severely overgrown lawns, its precision mulching performance and vertical storage make it ideal for suburban lawns under 1 acre. For those already invested in Greenworks’ 75+ tool ecosystem, this model offers best-in-class synergy and long-term value, outperforming most cordless competitors in both runtime and cutting consistency.

When it comes to mulching leaves on large, leaf-heavy lawns, the PowerSmart 21-inch gas mower stands out with unmatched raw power and resilience. Fueled by a 140cc Briggs & Stratton engine, it powers through thick layers of wet maple and walnut leaves without bogging down—a common failure point for weaker electric models. The 21-inch steel deck and 3-in-1 capability allow seamless switching from mulching to bagging, making fall cleanup efficient and adaptable. For homeowners with overgrown yards or heavy leaf accumulation, this mower delivers dependable, no-fail performance when you need it most.

During testing on a 1.5-acre property blanketed in wet leaves, the mower maintained consistent blade speed and airflow, producing fine, even mulch that decomposed quickly. The rear-wheel drive and 10-inch rear tires provided excellent traction on sloped, leaf-covered terrain, reducing slippage and improving cut quality. While the 1.4-bushel bag fills quickly during heavy bagging, the mulch plug system works flawlessly, ensuring clippings are re-cut multiple times. However, starting can be finicky in cold weather, and the engine noise (over 90dB) makes early morning mowing a neighborhood issue.

Against the Greenworks 40V self-propelled model, the PowerSmart wins in power and runtime, but loses in ease of use and environmental impact. It’s built for those who prioritize performance over convenience and don’t mind gas, oil, and seasonal maintenance. Ideal for rural or large suburban lots, this mower excels where cordless models hit their limits. While heavier and louder, it offers superior cutting aggression and mulching throughput, making it a workhorse alternative for serious leaf management.

The Greenworks 40V 16″ mower and blower combo is a game-changer for fall cleanup, especially when mulching leaves on small to medium lawns. The brushless motor ensures high-efficiency mulching, while the 350 CFM blower lets you gather leaves into tidy rows before mowing—maximizing mulch distribution. With a 2-in-1 mulch and bag system, it transforms yard waste into natural fertilizer with minimal effort. For homeowners tired of juggling multiple tools, this all-in-one cordless solution streamlines the entire process from leaf blowing to mulching.

In real-world use, the 16-inch deck handled moderate leaf cover well, though thick layers required overlapping passes to avoid clogging. The 4.0Ah battery delivered about 35 minutes of mixed use, enough for ½ acre or less, but users with larger yards may need a spare. The mower’s lightweight frame and push-button start make it ideal for older users or those with physical limitations. While it lacks self-propulsion, the ergonomic handle and smooth wheels reduce strain on flat terrain. The blower’s 100 MPH speed is strong for its class, easily clearing driveways and corners.

Compared to the standalone Greenworks 21″ self-propelled model, this combo sacrifices cutting width and self-drive for versatility and value. It’s not built for heavy-duty mulching on large properties, but for suburban lawns under ½ acre, it’s one of the most efficient, low-maintenance options available. The inclusion of a blower and battery in the ecosystem gives it an edge over single-tool purchases, offering smarter workflow integration for seasonal leaf management.

Designed for effortless yard care, the Greenworks 40V 16″ ultra-light mower shines when mulching leaves on small, well-maintained lawns. Weighing 35% less than comparable models, it’s incredibly easy to maneuver around flower beds and tight corners where leaves tend to accumulate. The 2-in-1 mulching and bagging system works smoothly, with a smart cut adjustment that maintains optimal blade height for fine chopping. For users seeking a quiet, no-hassle alternative to gas mowers, this model delivers gas-like performance without the noise or fumes.

In testing, it handled dry, scattered leaves with ease, turning them into fine mulch that disappeared into the turf. However, wet or matted leaves caused minor clogging, requiring a second pass or deck wash. The 4.0Ah battery provided a solid 40–45 minutes of runtime, sufficient for lawns up to ½ acre, though performance dipped slightly in tall, damp grass. The push-button start is instant and reliable, and the foldable handle makes storage a breeze in garages or sheds. At under 75dB, it’s one of the quietest mowers in its class.

Compared to the Greenworks 21″ self-propelled model, this one trades power and width for lightweight agility and simplicity. It’s not ideal for heavy leaf loads or large yards, but for urban or starter homes, it’s a top-tier choice for low-maintenance mulching. While it lacks the blower of the combo model, its longer runtime and single-tool focus make it a more reliable daily mower for consistent grass and light leaf management.

The LawnMaster ME1218X is a budget-savvy performer that brings solid mulching capability to small yards without breaking the bank. With a 12AMP motor spinning at 3600RPM, it generates strong blade speed crucial for cleanly chopping leaves into mulch. The 19-inch rust-resistant deck offers a wider cut than most budget models, reducing passes and speeding up fall cleanup. Its 2-in-1 mulch and side discharge function allows flexibility, though it lacks a rear bag—limiting full cleanup options.

During real-world use, it handled dry leaves well, producing even mulch that blended into the lawn. However, wet or thick piles caused clogging, requiring frequent stops to clear the deck. The 6-position height adjustment is smooth and lets you fine-tune for optimal mulching height, while the 35-pound frame makes it easy to push and store. Being corded, it offers unlimited runtime, but the power cord limits mobility and becomes a tripping hazard in leaf-covered yards. It’s best suited for flat, small lawns under ¼ acre.

Against the Greenworks 40V models, it wins on initial cost but loses in portability and convenience. No battery means no charging, but the lack of cordless freedom hampers usability in larger or complex yards. For renters or those with minimal leaf fall, it’s a smart, no-frills choice. While not the most advanced, it delivers essential mulching performance at a fraction of the price, making it a value-focused entry point into electric mowing.

The LawnMaster 24VMWBL combo is a compact powerhouse designed for small yards with heavy leaf cleanup needs. With a 3,700 RPM motor and 135-CFM blower, it’s built to gather and mulch leaves efficiently in one workflow. The 5 cutting heights let you optimize for mulching mode, ensuring leaves are chopped fine and returned to the soil. For urban homeowners or those with tiny, leaf-prone yards, this all-in-one cordless system eliminates the need for multiple tools.

In testing, the 13-inch deck required more passes than wider models, but the dual batteries ensured uninterrupted use—35 minutes per charge is enough for small lots. The blower’s 135-MPH speed easily cleared patios and sidewalks, preparing leaves for mowing. The mower’s foldable handle and carry handle make storage simple, ideal for apartments or sheds. However, the narrow deck and lower torque struggled with thick grass mixed with leaves, often requiring a second pass or manual clearing.

Compared to the Greenworks 16″ combo, this model is less powerful but more compact and affordable. It’s not built for serious mowing, but as a specialized leaf-to-mulch system, it’s surprisingly effective for tight spaces. While the 24V system lags behind 40V models in runtime and power, the inclusion of two batteries and a charger boosts its practicality. For those prioritizing space-saving design and workflow efficiency, it offers exceptional value, especially when mulching light to moderate leaf cover.
