Our favorite leaf mulcher, the Worx WG430 13-Amp Electric Leaf Mulcher, is on sale for $120.99 (save 36%) during Amazon's Cyber Week Sale. Hurry, this deal won't last long!
Few sights are as lovely as the red and gold hues of falling leaves, but having to rake and bag them'with no leaf mulcher in sight'can quickly make leaves lose their appeal. It only takes one good soaking rain for dried leaves to become a soggy mess, increasing the risk of lawn disease.
Shredding leaves in a leaf mulcher significantly reduces their bulk and, better still, creates organic mulch for use around perennial plants. We tested some of the best leaf mulchers to make yard cleanup easier, whether recycling the leaves at home or bagging them up to place at the curb.
Finding the right leaf mulcher for your needs depends on the amount of leaf accumulation, yard size, and your leaf collection preferences. Our test group included models with a variety of strengths and purposes. Our Best Overall pick is the Worx WG430 13-Amp Electric Leaf Mulcher thanks to its fast shredding and high efficiency. Check out our reviews based on this hands-on testing, and then read on to learn what to look for when shopping for the best leaf mulcher.
Photo: AmazonWe spent 5 days in a half-acre backyard grinding up fallen leaves with 11 different leaf mulchers. Each mulcher had to run the gamut of large and small as well as dry and wet leaves, along with whatever small twigs, pine cones, and acorns found their way into the mix. Note: While our testing included the Sun Joe CJ601E Electric Wood Chipper, we found that its narrow hopper and flywheel chopper are designed for grinding up sticks, not for shredding leaves.
The first testing day was under dry conditions, with slightly moist leaves that we had recently blown into a pile. For the handheld vacuum/mulcher models, we held the suction tube at or slightly above the level of the leaves, as they should be used according to each manufacturer's instructions. We simply turned on and fed the stand-alone models by the armload.
On the second day, we attempted to put the vacuum/mulcher models through more stressful conditions, feeding them with wet, matted leaves and large, leathery magnolia leaves. During this test, we also pushed the suction tubes farther into the leaf piles to see if they would become clogged or simply stop. To stress the stand-alone models, we used large baskets to 'force-feed' extra-large quantities.
Ultimately, all of the models that made our list passed both tests. For the average testing, each mulcher shredded without hesitation, filling its bag. During the stressful testing, several clogs occurred, but none were catastrophic, nor did they take more than a little thump on the side of the suction housing to clear the clog. In all, each leaf mulcher in this group worked as expected or even better than expected.

This electric Worx leaf mulcher is designed with the sole purpose of shredding leaves, which it does quickly and efficiently. The upright model operates via a heavy-duty 12- to 14-gauge extension cord, and its rugged 13-amp motor provides an 11:1 mulch reduction ratio.
The cylindrical molded plastic unit sits atop strong steel legs (minor assembly required). Rather than metal or plastic blades, this leaf mulcher uses the same type of plastic line found in string trimmers. It features a large intake hopper and shreds up to 53 gallons of leaves per minute.
The Worx WG430 shreds much faster than any blower/vacuum-type leaf mulcher we tested. We dropped leaves into the hopper by the armload (or basket full), and they were gone before we could pick up the next load, allowing us to fill a 30-gallon trash bag with shredded leaves in less than 5 minutes. The trimmer lines shredded five bags of leaves and other fine yard debris before we needed to replace them, a task that took under 2 minutes. For users with a lot of leaves to shred, this mulcher does the job quickly and efficiently, even bagging the material for disposal.

What We Like
A handheld cordless leaf blower vacuum mulcher offers the freedom of mobility and easy storage. The Ryobi 40V Vac Attack leaf mulcher vacuum uses a durable steel impeller to shred leaves and debris to 1/16 of their original size and produces enough vacuum power to fill eight 30-gallon bags in 12 minutes. It conveniently shares the same 40V cordless power platform with more than 80 other Ryobi tools and comes with a 5 Ah battery and charger.
This leaf vacuum/mulcher performed very well with both freshly fallen dry leaves (on the low-speed setting) and old, moist, and matted leaves and debris (on the high-speed setting). The heavy-duty vacuum bag held more debris than most of the other handheld units we tested, which was ideal for bigger piles. It was easy to unload directly into lawn and leaf bags. However, we also noted that this tool worked best where the leaves were already piled up, since even with adjustable wheels on the suction tube, the large bag made it more difficult to maneuver.
Being a 'single tasker' might be a con for some shoppers. Unlike other cordless leaf suction machines, the Ryobi vacuum/mulcher does not convert to a leaf blower. Those who are most interested in space savings might instead prefer a three-in-one option. In our tests, we alternated between blower and vacuum frequently, and it would have been more of a hassle to switch back and forth. We preferred to keep a dedicated leaf blower on hand at all times.

The Worx WG512 is much improved over the previous Trivac incarnation. It uses a single tube for both blower and vacuum modes, with an easy-to-use dial to switch modes. The 12-amp corded electric motor uses an upgraded metal impeller fan to grind leaves and debris at a mulching rate of 16:1. It weighs in at 8.6 pounds and moves air at a rate of up to 600 cubic feet per minute (CFM).
In our tests, the WG512 showed a good balance of power and relatively quiet operation, with a noise operating level listed at 70 decibels. It easily pushed wet and dry leaves around the yard and then quickly dispatched them in vacuum/mulcher mode. When we forced the issue by shoving the vacuum tube deep into a leaf pile, the tube clogged briefly but righted itself as soon as we pulled it back out of the pile. The single-tube design, simple mode change dial, and better-than-average air handling ability made this model stand out. As a handheld corded electric model, it seems best for small to midsize yards with moderate to heavy leaf cover.

Put the power of lithium-ion energy to work with the Greenworks cordless leaf mulcher. This battery-operated mulcher includes a high-performance G-MAX 40V lithium-ion battery that produces up to 340 CFM of blowing power and runs up to 20 minutes on the highest mode. It offers six speed adjustments and both a narrow blowing tube and a wider-angle vacuum tube for versatile yard cleanup. The mulcher weighs 9.92 pounds, features a 10:1 reduction ratio and aluminum-alloy impeller blades, and includes a reusable mulch collection bag.
We wanted to see if this cordless tool had adequate power to collect and shred leaves without changing batteries or running out of charge. After using it in blower mode to collect a pile of leaves, we switched to vacuum mode and proceeded to fill the collection twice, plus another partial bag. Altogether, it worked for more than 20 minutes on the highest power setting.

Shoppers with bigger lots and more leaves to deal with may find a gas-powered leaf mulcher most convenient. The compact handheld Husqvarna 125BVx saves storage space while eliminating the hassle of charging batteries and running extension cords. It is powered by a 28cc 2-cycle engine that generates airflow of 425 CFM at speeds up to 170 miles per hour (mph). In vacuum/mulcher mode, it mulches leaves and other small yard waste at a 16:1 ratio. We also selected this model for our Best Leaf Vacuums guide.
Several details on this machine make it a superior choice. The easy-crank engine features a low resistance recoil starter in addition to an auto return stop switch to eliminate flooding at startup. In our tests, it started on the first or second pull every time. Then, the operator can use the variable trigger for immediate responsiveness or set the cruise control lever for consistent blow force to eliminate hand fatigue. Other comfort features include an overall lightweight build (just over 9.5 pounds), an anti-vibration handle, and an ergonomic design with the blow tube in line with the handle for optimal performance. It also includes a shoulder strap to reduce user fatigue.
We noted the vacuum's powerful suction and resistance to clogging. It filled the bag noticeably faster than the battery and electric-powered models, but we did not record the times. Also, the metal mulching impeller worked aggressively on everything small enough to enter the tube, including hard items like sticks and acorns. Although we didn't love the curved vacuum tube design at first (the other handheld blower/vacuums had only a short, straight pipe coming off the blower into the bag), it functioned well once we determined the best way to position it.

Blow dry leaves into a pile and then vacuum them up and shred them with this three-in-one electric leaf blower and mulcher from Black+Decker. This handheld machine weighs in at 8.1 pounds, and it includes a detachable shoulder strap, reusable bag assembly, and three disposable bags. The unit boasts variable-speed control with up to 400 CFM airflow and air speed up to 250 mph. It also features a tough metal impeller that produces a 16:1 reduction ratio, resulting in finely shredded leaves that can be added to the compost bin or used to mulch plants. A heavy-duty 12- to 14-gauge exterior extension cord (sold separately) is needed to operate this versatile tool.
We liked the convenience of having a blower, vacuum, and mulcher in one tool. Changing from blower to vacuum was easy and only took about 1 minute: Using a flathead screwdriver, remove the blower tube and air intake cover and attach the vacuum tube and leaf collection bag. This tool performed well in both modes, with ample power and minimal clogging in vacuum mode.

For large properties where leaf-drop season lasts months rather than weeks, a dedicated walk-behind leaf vacuum and mulcher makes the job much more manageable. The self-propelled Billy Goat KV601SP is an excellent choice for bigger yards with lots of trees. It comes equipped with a 190cc gas engine to power the 27-inch vacuum nozzle with a massive 1,700 CFM of airflow. The strong suction picks up leaves, seeds, mulch, blooms, branches, and litter from lawns, landscape beds, and pavement. A metal impeller shreds the material at a 6:1 reduction ratio, and the large 40-gallon zipperless vacuum bag reduces downtime for dumping. For improved functionality and efficiency, a 7-foot vacuum hose attachment is available (sold separately).
The powerful suction and steady-rolling self-propelled feature made this vacuum and mulcher a pleasure to operate. However, the price and single-task nature of the machine realistically limits its practicality to large properties with extensive leaf-cleaning needs. Moving two to three times the air volume of the other lawn vacuum mulchers we tested, it worked incredibly fast: 5,000 square feet of lawn and 1,000 square feet of pavement vacuumed with the debris mulched and bagged in about 15 minutes, or about the same amount of time it took to blow leaves into piles for the other leaf mulchers.

Electric three-in-one leaf mulchers are popular because they're so easy to use, and this Toro model was the breeziest of the bunch we tested, largely thanks to the toolless switching from blower to vacuum. The machine generates up to 340 CFM of blowing force to move leaves, small twigs, and other debris from around HVAC units, decks, and fences. We found that to be plenty of power to gather all of the leaves into a pile and then suck them up into the metal impeller leaf shredder. The only material that slowed down this machine was coarse, wet, matted leaves.
The mulcher weighs just 8.5 pounds, making it easy to carry. It also includes a reusable collection bag and two additional tube attachments to concentrate air power. The impeller features magnesium-serrated metal blades that resist rust and corrosion. It shreds leaves at a 16:1 reduction ratio, a small size that's sure to quickly decompose in a compost pile and also suits layering around plants to reduce weeds and retain soil moisture.

For yards with lots of leaves, an electric stand-alone leaf mulcher shredder is often the best bet, and this Flowtron model is a worthy contender. Its 5.9-amp motor will run all day, with just a few stops along the way to install new trimmer lines. It grinds up dry leaves at a rate of up to 55 gallons per minute. Choose from fine, medium, and coarse mulching settings, based on material. The fine setting is great for dry, thin material like pine needles and dry leaves, while the coarse setting is better suited for wet matted leaves and grass clippings. An onboard safety shutoff kills the engine if it overheats.
This stand-alone model almost made the cut as our best overall pick since it was a viable option in terms of performance. However, the setup proved to be far less user-friendly. The plastic hopper arrived in two halves, requiring assembly by aligning tabs and installing four screws. Assembling the two halves of the metal stand requires two screws, two brackets, and two wing nuts. Though this wasn't difficult, these engineering choices made the process more clunky and complicated than it had to be. In action, we liked the lower working height but found it necessary to use trash bags instead of paper lawn and leaf bags for collection because the base is so low to the ground.

Consider ease of operation, efficiency, and performance when selecting the best leaf mulcher for a specific job. These factors are dependent on the following features.
Leaf mulchers are all designed with one primary task: shredding leaves, typically with spinning impeller blades. Yet certain features are worth considering when choosing the type of mulcher that best suits a particular yard or job. Leaf mulchers offer a variety of power options, such as an electrical cord, a gas engine, or a rechargeable battery. In addition, while many leaf mulchers are handheld, some are stationary. As with all power tools, read and follow the manufacturer's safety precautions, and do not operate a leaf mulcher when small children are nearby.
Corded leaf mulchers, which fall into the electric leaf blower category, feature motors rated in amps that range from around 8 to 14 amps. The higher the amps, the more powerful the motor. Corded models are quieter than gas-powered models, and there is no fuel to mix or flammable gas to store. While charging a battery isn't a concern with a corded leaf mulcher, users will be limited to the length of an extension cord, which usually tops out at around 100 feet. A handheld corded mulcher weighs about 6 to 9 pounds, so it's easy to use without developing shoulder or arm fatigue.
Gas-powered leaf mulchers provide ample power with no risk of tripping over an extension cord and no battery to charge. The engine of a gas leaf mulcher is rated by its size in cubic centimeters. The larger the number, the more powerful the engine. An engine is also rated by the type of fuel it requires: A 2-cycle gas engine requires mixing gasoline with engine oil at a ratio determined by the manufacturer, while a 4-cycle gas engine runs on pure gasoline only. While a gas leaf mulcher is portable because it isn't tethered to a cord, it will weigh quite a bit more'between 10 and 17 pounds'than any corded or cordless model. Another downside to gas models is the fumes they emit.
Like corded mulchers, battery-operated cordless leaf mulchers won't require users to mix fuel or be exposed to toxic fumes. Cordless leaf mulchers are ultimately portable since they're fairly lightweight and aren't restricted by the length of a cord; however, the average lithium battery runtime is between about 15 and 35 minutes, depending on the voltage. These rechargeable batteries average 20 to 40V. The higher the voltage, the longer the runtime. Buying a second battery and keeping it charged will allow for much longer use of a cordless mulcher.
The majority of leaf mulchers are handheld models that vacuum up leaves and then pass them through spinning impeller blades for shredding. Many handheld models also feature leaf-blowing capability to blow leaves into piles for easier vacuum collection.
However, some shoppers prefer the ease of use of a stand-alone model. You can position these leaf mulchers in a central spot in your yard and dump dried leaves into a top intake chute'known as a hopper'for shredding. A collection bag attaches to a discharge chute at the bottom of the hopper.
Most leaf mulchers have metal mulching blades that spin at rapid speeds to chop and shred leaves into tiny bits, but some models use heavy-duty plastic blades or even string-trimming line. All three options can shred leaves, but metal blades are often more durable.
The mulching ratio, also known as the reduction ratio, indicates how much the tool will reduce the leaves' overall size. For example, a mulching ratio of 10:1 indicates the mulcher will reduce 10 bags of dried leaves to shreds that will fit in a single bag. Typical mulching ratios range from 8:1 to 18:1, with the highest ratios producing the smallest shreds. Keep in mind that small shreds will decompose more quickly in a compost pile.
Leaf mulcher capacity relates to the amount of air the machine moves in CFM. Most corded and cordless leaf mulchers range from around 175 to 500 CFM, with the highest-capacity models designed for heavy-duty leaf clearing. Gas leaf mulchers, which are more powerful, tend to have higher capacities, ranging from 450 to 700 CFM.
Stand-alone leaf mulchers have a single function: They shred leaves dropped into their hoppers. Handheld models often do more, including blowing leaves into a pile and then vacuuming them up for shredding. While a few handheld leaf mulchers vacuum but do not blow, models with three functions operate as leaf blowers and leaf vacuums.
Both corded and cordless leaf mulchers are easier to use than gas models because they don't require mixing fuel, adding engine oil, servicing a carburetor, or using a hand recoil to start the engine. However, fans of gas models may consider the greater power derived from a gas-powered leaf mulcher to be worth the extra effort.
All power tools, including leaf mulchers, make some noise, but cordless and corded models are fairly quiet at approximately 60 to 63 decibels'comparable to the sound of conversational speech. Gas-powered leaf mulchers are quite a bit louder at around 85 to 90 decibels, or comparable to the sound of busy street traffic from the curb. Shoppers will want to check their city ordinances prior to purchase; an electric leaf mulcher may be preferable or required in communities where loud noises are discouraged or prohibited.
Yard cleanup may seem like a straightforward task, but first-time shoppers of leaf mulchers might need more information. Check out the answers to some of the most frequently asked questions about leaf mulchers.
Q. Are leaf mulchers worth it?Using a leaf mulcher will certainly save you time and labor. Plus, spreading a layer of shredded leaves around the base of plants helps reduce weed growth, improves soil content, and retains moisture in the soil.
Q. What is the difference between a mulcher and a chipper?While both items will produce small bits of biodegradable material for use as mulch around plants or for adding to a compost pile, a leaf mulcher handles only leaves and tiny twigs, while a wood chipper shredder can shred small tree branches.
Q. What can I put in a mulcher?A leaf mulcher is only intended for dry leaves. Avoid sucking up acorns and twigs larger than 0.125 inch in diameter and don't mulch green leaves or grass clippings. Green plant matter can clog the blades of a leaf mulcher.
Q. Should I shred leaves before composting?Yes, shredded leaves take much less time to decompose. Not only do shredded leaves offer microbes a larger surface area for them to do their work, but shredded leaves are also less likely to clump up. This would make decomposition take even longer.
Q. How long does it take for mulched leaves to decompose?It takes about 1 year for chopped leaves to decompose, while whole leaves might not decompose completely for 2 to 3 years.
Q. Do leaf mulchers work on wet leaves?Wet leaves can create clogs in leaf mulchers. Machines that are more heavy duty can usually handle wet leaves more easily, though.
Q. What is the lifespan of a leaf mulcher?Leaf mulchers should last at least 5 years. After that, lifespan depends on maintenance and frequency of use.

The leaves are falling, which means it's time to start raking and figuring out what to do with them. This year, try turning your fallen leaves into mulch for your garden!
The following is an excerpt from Will Bonsall's Essential Guide to Radical, Self-Reliant Gardening by Will Bonsall. It has been adapted for the web.
Photographs courtesy of Will Bonsall unless otherwise noted.
For those who question the fertilizing power of tree leaves, I would share a couple of anecdotes. Although I have many acres of hardwood forest where I could collect my own leaves, I usually prefer to haul them from the town of Farmington, 8 miles (12.9 km) away. I'm doing the people of Farmington a favour by hauling theirs away (the town used to do it but no more), plus they're already raked into piles, relatively free of twigs and branches.
Of course I always ask the owner if I may take them, even though the response is predictably something like 'What! Is the pope Catholic?' At one home on a shady side street,I asked the owner, an elderly woman with a charming Austrian accent, and she answered graciously, 'No, I want them myself.' Intrigued, I asked wherefore, and she replied, 'I need them for my garden.'
Delighted, I probed further. She, having no known ideological views on the subject, relied exclusively on the maple leaves because they were what she had'the shade-free portion of her yard was wholly occupied by her garden, so there was little lawn to supply grass clippings, and she had no access to manure.
She had no formal system for shredding or composting; she merely said: 'I mull them over from time to time.' That had been her 'system' for years, and the heavy-feeding cabbages and leeks I saw testified to her success. The huge pile of leaves in her yard was waiting to be converted into next year's sauerkraut!
Second story: I once persuaded the Town of Farmington street commissioner that they should truck their curbside leaves up to my place rather than to the town dump. Yes, he hastened to agree, it made good sense for everyone. The first two truckloads landed in my leaf dump, and I congratulated myself that henceforth I would merely wait for the annual windfall.
Next year they didn't show up, so I asked the street commissioner, what gives? Well, it turns out that they need them at the landfill. Need them? I repeated dumbly. Ayuh, it seems they need them to add to the cleanings of the fairground horse stables. Ah, says I knowingly, it's to balance the excess nitrogen in the manure.
Weeell, not quite, he corrects me; it's rather that all that sawdust bedding makes the piles cold, despite the pony doo-doo. What! They're using 'my' leaves to heat up horse-hockey so it will be well composted? And does it? Yep, assured the commissioner with no irony intended, works slick as shit. Now understand, this good fellow was not a vegan, not into organic or sustainability'for all I know he could be a Republican'yet don't try to tell him that leaves lack nitrogen.
Most of the ways I use leaves require shredding, and that involves some kind of shredder. In my case I have an Amerind-MacKissick chipper/shredder designed to work as an attachment with my Gravely 12-horsepower walking tractor, but the chipper/shredder can be powered by any other PTO source or can be purchased with its own self-contained engine.
For chipping brush the 12 hp is really needed to accomplish anything, but for shredding leaves a lighter power source might be quite adequate. An advantage of mounting this shredder on something is that it is easier to move about'on its own it's cumbersome to move any distance.
My Gravely, by the way, is a magnificent machine, which is probably why Gravely's are no longer made. Because such walking tractors have several interchangeable attachments (mowers, snow blowers, tillers, and more), you don't need to own several engines, all of which require maintenance.
On the other hand that means that if the one tractor is out of order, you cannot do any of those jobs. Changing attachments is a rather minor nuisance and should not weigh very heavily against that option.
The safety grating on my chipper/shredder won't allow anything less than 3'4 inch (1.9 cm) in size to pass through, so the product has a very uniform consistency, perfect for applying. I simply walk down the paths with a large rubber barrel full of shreds held on one shoulder and with my free hand create a blizzard of leaf confetti over the beds.
The crop plants are usually a few inches tall, and the shreds drift down and settle down nicely around the plants, making a tight and effective mulch with minimal effort. That's why it is important that they be consistently fine'confetti-like: so that no clumps of whole leaves will smother the crop. Also, shredded leaves stay put in a breeze much better than whole leaves, especially once they've been wet and settle into a tight 'felt.'
Another reason for shredding leaves is the twigs. Although I remove the larger branches for chipping separately, most leaves have a lot of fine twigs that are a nuisance to pick out, yet I don't want them left whole. This is especially an issue with leaves collected in the forest or from lawns with big old trees (the ones with deepest roots and thus better trace-mineral content). When fed through the shredder they are reduced to harmless little chips that bother nothing, although you may need to pre-snap longer twigs so they don't block the chute.
If I'm using partly wet leaves they will plug up the grate, but if I remove the grate they'll come out too fast, only half shredded. Half shredded is okay as long as I can put them right back through again, giving me a product somewhat like the confetti, though not as uniform. For mulching paths and wider-spaced crops, and for making compost, this is quite satisfactory. (Remember, once the grate is removed, there's nothing between you and the spinning hammer mills, so stand clear.)
I need to stockpile as much confetti as possible when they're crispy and dry, and so I race to shred those as fast as they come in, and pack them into a large (8 × 10 × 4-foot, or 2.4 × 3.0 × 1.2 m) covered plank bin that holds roughly 2 tons. If I have a real lot of confetti, I can pack it into feed bags and cover them with a tarp against rain and snow. I use lots of those banked up against the exterior door of my cellar for insulation during the winter.
A well-powered chipper/shredder is the best way to shred leaves, but it is not the only way. My father used to pile his leaves up by the garage door and run through the pile repeatedly with his push power mower, stirring it up between passes. Cousin Tom makes his into a long, very deep pile (3 feet, or 0.9 m) and wades through it repeatedly with his rototiller, regathering it as it spreads out.
And of course, we all know the hands-down most efficient way of shredding leaves: You gather them all into a huge pile in the middle of the lawn and tell your kids and all the neighbour kids: 'Stay out of this.' Within hours the pile will be reduced to molecules. (To accelerate the process you could hang a used car tire from an overhead limb.)
The problem with all these alternatives is the lack of consistency; some will be crushed to powder while some large pieces will remain. This isn't a big problem for some uses (say, compost), but for mulching closely spaced crops, including grain, the crude shreds are more difficult to apply. For mulching more wide-spaced crops, like cabbage and tomatoes, and for paths, the cruder shreds produced by a lawn mower work well.
I often end up with more leaves than I can shred immediately. When I have run out of time I have also stored whole leaves loose in a hex-wire (aka chicken wire) enclosed leaf dump, which I cover with a well-weighted tarp. The leaves stay pretty dry until I can shred them the following spring or summer.
During this time the bottom layer will get somewhat damp from wicking ground moisture. If I am short on confetti the following spring, sometimes I just spread the dampish leaves out on a tarp to re-dry for some hours and then shred them, although usually I just use the crude method, double-shredding without the grate in place.
Some degree of shredding is necessary for composting leaves, because whole leaves tend to form a soggy mat that will take forever to break down. In fact that was what got me into shredding in the first place: Because I could use only thin layers of whole leaves in the compost pile, I was always using much less than I wanted, in proportion to the hay and other stuff.
Once shredded, leaves can be the major ingredient in my pile, quite compatible with my eco-efficiency obsession. Indeed, aside from leaves and brushwood, my composting of corn, sunflower, and amaranth stalks would be very difficult without first shredding them. By reducing the volume and exposing more surface of those materials, I greatly increase the rate of decay, plus the biological heat that renders a superior end product.
