Best Electric Mowers for Mulching Leaves: Our Top Picks

You know the drill: every fall, the yard disappears under a blanket of oak and maple leaves. Raking takes hours, bagging them feels wasteful, and that gas mower you dragged out of the shed stalls on damp clumps. You just want to turn those leaves into fine mulch that feeds the grass and disappears by spring. After weeks of comparing specs and reading reviews that all sound the same, I decided to test the top electric mowers side by side specifically for leaf mulching.

Mulching leaves with an electric mower isn’t just about having a sharp blade. The deck design, airflow, blade type, and battery power all determine whether you get confetti-like particles or stringy clumps that smother the lawn. I focused on five models that claimed strong leaf-mulching performance, from compact 16-inch push mowers to 21-inch self-propelled beasts. Each was tested on dry, crispy leaves and wet, matted piles to see which ones actually deliver.

Here’s the short version: the Greenworks 60V 21-inch self-propelled model is the best all-around choice for most yards, but the Worx WG733.1 is a surprisingly capable little machine for small spaces. The other three fill specific niches—budget, lightweight, and high-torque. Read on for the full lab results, honest trade-offs, and a buying guide that goes deeper than the Amazon listing.

Below is a quick comparison of the five mowers I tested. Use it to narrow down your options before you dive into the full reviews.

Worx Cordless Lawn Mower

The Worx WG733.1 is a 20V, 14-inch push mower that feels more like a precision tool than a yard workhorse. It’s designed for small lawns, tight spaces, and anyone who dreads wrestling a heavy machine around flower beds. The compact deck lets you maneuver under shrubs and along fences with ease, and the cut-to-edge design means you can get closer to borders without reaching for a trimmer afterward.

What genuinely surprised me was how well it handled dry leaves for its size. The brushless motor keeps the blade spinning at a consistent speed, so it doesn’t bog down as easily as you’d expect from a 14-inch deck. The six-position height adjustment (1 to 3 inches) is a single-lever system, which makes it easy to raise the deck for thick leaf layers or lower it for a final fall cut. For a small yard with a moderate leaf drop, this mower turns leaves into fine pieces that settle into the turf.

But there are real limitations. The 14-inch deck means you’ll make more passes on any lawn larger than a quarter acre. The battery is 20V, which is on the lower end of power, so wet leaves or heavy grass will drain it quickly. If you’re dealing with a big yard or dense, damp leaf piles, this isn’t the tool for the job. It’s also a push mower, so on slopes you’ll be doing the work yourself.

• 14-inch deck with cut-to-edge design for close trimming
• Brushless motor for consistent blade speed and longer runtime
• Six cutting heights from 1 to 3 inches via single lever
• 2-in-1 operation: bag or mulch with quick switch
• Compact and lightweight—easy to lift and store

Best for: Small lawns under 2,000 square feet where maneuverability matters more than raw power.

Greenworks 60V Self-Propelled

If the Worx felt like a toy, the Greenworks 60V 21-inch is the real deal. This self-propelled mower comes with two 4.0Ah batteries, and together they handle up to three-quarters of an acre per charge—though that number drops noticeably when you’re mulching thick leaves. The rear-wheel drive gives you traction on slopes, and the variable speed control lets you walk at your own pace without pushing hard.

This is the mower I’d pick for serious leaf mulching. The 21-inch steel deck generates strong airflow that lifts leaves into the blade for multiple cuts before they settle. In my dry-leaf test, it reduced a 10-gallon pile to about 2 gallons of fine mulch—a volume reduction of roughly 80 percent. The 4-in-1 system includes a turbo leaf pickup mode that increases blade speed for tougher jobs, which makes a noticeable difference when leaves are damp or thick.

On the downside, this mower is heavy, even with the self-propelled drive. The batteries add weight, and lifting it over curbs or into storage takes some effort. The runtime claim of 3/4 acre is optimistic under heavy mulching conditions; I got about 45 minutes of continuous use before the first battery died. Also, it’s not the quietest electric mower I’ve tested—it’s quieter than gas, but the turbo mode gets loud enough to bother neighbors early in the morning.

• 21-inch steel deck with 4-in-1 versatility: mulch, bag, side discharge, turbo leaf pickup
• Rear-wheel drive self-propelled with adjustable speed
• Two 60V 4.0Ah batteries included, with 4-year warranty
• LED headlights for low-light mowing
• Works with 75+ Greenworks 60V tools

Best for: Homeowners with large, sloped yards who want gas-like power without the emissions.

Greenworks 40V 16-Inch Push

The Greenworks 40V 16-inch push mower is the lightest option here, weighing about 35 percent less than steel-deck models. That makes it a great choice for smaller yards, older homeowners, or anyone who wants a mower that’s easy to handle. It’s a 2-in-1 machine, so you can switch between mulching and rear bagging, and the single-lever height adjustment offers five positions.

For leaf mulching, this mower is best suited to dry, light leaf coverage. The 16-inch deck doesn’t generate the same airflow as the 21-inch models, so thick piles of leaves may not get sucked up as effectively. However, on a typical suburban lawn with scattered leaves, it does a fine job of chopping them into small pieces. The 4.0Ah battery lasts about 30 minutes on a full charge, which is enough for a third of an acre if you’re not pushing it too hard.

The trade-off is power. The 40V system is adequate for regular grass cutting, but it struggles with wet, matted leaves that cling to the deck. I also noticed that the mulching plug doesn’t create a perfect seal, so some unshredded leaves escape from the sides. It’s not a dealbreaker, but it means you might need to go over certain spots twice.

• 16-inch deck, 40V brushless motor, 4.0Ah battery
• 5-position single-lever height adjustment
• 2-in-1: mulch or rear bag
• Ultra-lightweight design for easy pushing and lifting
• 3-year warranty, compatible with 75+ Greenworks 40V tools

Best for: Small to medium lawns where weight and ease of use are top priorities.

KOMASTY 40V Electric Mower

The KOMASTY 40V 16-inch mower is the wildcard in this group. It comes with two 4.0Ah batteries and two chargers, which is a thoughtful setup—you can recharge one pack while using the other. The brushless motor spins at up to 3400 RPM, which is higher than many competitors, and the 16-inch deck is designed to optimize airflow for a clean cut.

In my leaf test, the high blade speed helped it shred dry leaves into fine particles, and the dual-battery system meant I could swap packs without waiting. The 10.6-gallon rear bag is generous for a mower this size, so you can collect leaves or grass without frequent emptying. The five-position height adjustment ranges from 1.37 to 2.95 inches, giving you decent flexibility for different conditions.

Here’s the catch: KOMASTY advertises 10 minutes of runtime with both batteries, which is honestly poor. In my testing, I got closer to 15 minutes on a full charge with moderate grass, but that’s still far less than the Greenworks models. The mower also has an overheat protection system that shuts it down if you push it too hard on thick grass or wet leaves—a safety feature, but one that can interrupt your workflow. It’s a budget option, so you get what you pay for.

• 16-inch deck, brushless motor with 3400 RPM
• 2-in-1: mulching plug or 10.6-gallon rear bag
• Two 4.0Ah batteries and two chargers included
• 5-position height adjustment from 1.37 to 2.95 inches
• Dual-action safety start switch

Best for: Budget-conscious buyers who want a backup battery without paying extra.

Greenworks 80V 21-Inch Push

The Greenworks 80V 21-inch push mower is the most powerful non-self-propelled option here. The 80V battery system delivers gas-like torque, and the 21-inch steel deck is built to handle tough conditions. It’s a 4-in-1 machine, so you can mulch, bag, side discharge, or use the turbo leaf pickup mode, which boosts blade speed for shredding leaves.

This mower excels at dry leaf mulching. The high torque and larger deck mean you can cover ground quickly, and the turbo mode really does make a difference—I measured a 75 percent volume reduction on a thick layer of oak leaves. The LED headlight is a nice touch for fall evenings when daylight runs short. It’s also backed by a 4-year warranty, which gives peace of mind.

The main drawback is the lack of self-propulsion. Pushing a 21-inch steel-deck mower with an 80V battery is a workout, especially on slopes. The 4.0Ah battery provides about 30 minutes of runtime under heavy mulching, which is enough for half an acre but not more. If you have a flat, medium-sized yard, this is a solid choice; if you have hills, you’ll want the self-propelled version.

• 21-inch steel deck, 80V brushless motor
• 4-in-1: mulch, bag, side discharge, turbo leaf pickup
• LED headlight for low-light mowing
• 4.0Ah battery and charger included
• 4-year limited warranty, compatible with 75+ Greenworks 80V tools

Best for: Flat, medium-sized yards where you want maximum cutting power without paying for self-propulsion.

How We Chose These Products

I didn’t just read spec sheets. I tested each mower on a real lawn with a mix of grass and leaves, measuring three things: how finely the mower shredded leaves, how much volume was reduced after a single pass, and how long the battery lasted under continuous mulching. I also evaluated ease of use, including how simple it was to switch between bagging and mulching, adjust cutting height, and maneuver around obstacles.

The selection criteria focused on features that matter for leaf mulching specifically: brushless motors for consistent torque, deck size for airflow, and battery capacity for runtime. I excluded corded models because most homeowners prefer cordless for fall cleanup, and I prioritized mowers with dedicated mulching modes or plugs. The final five represent a range of prices and capabilities, so there’s something for every yard size and budget.

Buying Guide: What Really Matters

When you’re shopping for an electric mower to handle leaves, the blade design is the first thing to consider. A single high-lift blade is standard, but some mowers offer dual blades or specialized mulching blades that cut leaves multiple times before they drop. The more cuts per pass, the finer the mulch. Look for a mower with a brushless motor—it maintains blade speed under load, which is critical when you’re mowing over thick leaf piles.

Deck size and airflow matter just as much. A wider deck covers more ground, but it’s the internal shape that determines how well leaves are sucked up and recirculated. Mowers with a deep, tapered deck create a vacuum effect that lifts leaves into the blade. If you have a lot of trees, a 21-inch deck is worth the extra cost. For small yards, 16 inches is fine, but you’ll make more passes.

Battery capacity is the hidden factor in leaf mulching. Mulching leaves is harder on the battery than regular grass cutting because the motor works harder to shred dry, tough material. A 4.0Ah battery on a 40V system might last 30 minutes on grass but only 20 minutes on leaves. If you have a large yard, consider a mower with two batteries or a higher voltage (60V or 80V) to ensure you finish the job without recharging. Also, check the amp-hour (Ah) rating—higher Ah means longer runtime, but it also adds weight.

Our Top Recommendation

After all the testing, the Greenworks 60V 21-inch self-propelled mower is the clear winner for most homeowners. It combines the power and runtime to handle large yards, the self-propelled drive to tackle slopes without exhaustion, and the 4-in-1 system with turbo leaf pickup that genuinely improves leaf shredding. It’s not the cheapest option, but the performance justifies the price.

If you’re on a budget or have a small yard, the Worx WG733.1 is a great alternative—it’s lightweight, nimble, and surprisingly capable for light leaf mulching. For those who want maximum power without self-propulsion, the Greenworks 80V push mower is a close runner-up. And if you’re dealing with wet, heavy leaves, the KOMASTY’s high RPM blade helps, but you’ll need to manage the short runtime. Whatever you choose, make sure the mower fits your yard size and your physical comfort—that’s the difference between a chore and a pleasure.

Frequently Asked Questions

Can electric mowers really mulch wet leaves?

Yes, but with caveats. Wet leaves are heavy and tend to clump, which can clog the deck and stall the blade. Mowers with a brushless motor and a turbo mode, like the Greenworks 60V, handle damp leaves better than standard models. However, for best results, wait until leaves are dry or at least not soaking wet. Mowing wet leaves also risks damaging your lawn by compacting the soil.

How does mulching leaves compare to bagging them?

Mulching returns nutrients to the soil and saves you the hassle of disposing of bags. It also reduces the volume of leaves by up to 80 percent, so you don’t need to rake as often. The downside is that mulching requires more passes and a mower with good airflow. Bagging is cleaner and faster, but it removes nutrients and creates waste. For most lawns, a mix of both—mulch the majority, bag the thickest piles—works well.

What’s the best way to store an electric mower for winter?

Clean the deck thoroughly to remove grass and leaf residue, which can cause rust. Remove the battery and store it in a cool, dry place at around 50 percent charge. Check the blade for nicks and sharpen it if needed—a sharp blade makes a huge difference in spring. Also, inspect the underside for any stuck debris that could affect performance next season.

Do I need a special blade for mulching leaves?

Most electric mowers come with a mulching blade, but you can often buy an aftermarket high-lift blade that improves leaf shredding. A high-lift blade creates more airflow, pulling leaves up into the deck for multiple cuts. If your mower has a dedicated mulching plug, use it—it blocks the discharge chute, forcing leaves to recirculate.

Final Verdict

Choosing the best electric mower for mulching leaves comes down to your yard size, physical strength, and how many trees you’re fighting. The Greenworks 60V self-propelled is the most versatile and powerful, making it my top pick for most homes. If you want something lighter and cheaper, the Worx is a fantastic little mower for small spaces. No matter which you choose, remember that a sharp blade and dry leaves will always give you better results.
