Our Unbiased Reviews
  1. 1. Efcut C30 7HP 212cc Heavy-Duty Mini Wood Chipper

    • Chute windows allow monitoring of blade and blockages
    • Mulches leaves and yard debris into fine material
    • Comes with safety gear and a 45-gallon bin
    • It's really expensive
    • Shipped in two separate containers
    • Be sure to fill reservoir with oil before starting

    The Efcut C30 7HP 212cc Heavy-Duty Mini Wood Chipper is a real close copy of the Landworks 7HP 212cc Gas-Powered Mini Wood Chipper; it’s got the same sized engine and basic features. At first glance, you might think it’s the same thing, just painted orange instead of blue. However, the Efcut C30 improves upon a few things that we’ll detail below.

    This wood chipper shreds branches, limb, and yard debris up to three inches in diameter. The reduction ratio is a healthy 20:1 with an elongated top adjustable discharge chute. That ratio is really good for creating your own fine mulch for the flower beds. 

    This wood chipper is powered by a 7HP 212cc 4-stroke single cylinder gas-powered engine. While Efcut doesn’t specifically call this out, ethanol is not recommended to fuel this machine. The engine is about as basic a gas setup as there is with a manual choke, throttle, power switch, gas shut-off, etc. You’ll need to fill the oil reservoir yourself as it’s not shipped with any.

    The feed bin and discharge chute are all metal with a thick coat of paint. Blades are supremely sharp and will whittle down anything you throw at it up to a three-inch diameter. Because of the higher reduction ratio and shredding power of this wood chipper, leaves and brush can be mulched effectively along with sticks and branches. This wood chipper also has another advantage: two convenient check windows, one in the front to check blade status, and one in the back for clearing blockages.

    A nice touch: this wood chipper comes with a 45-gallon nylon collection bin, replacement blade, wrenches, and protective gear in the form of earplugs and safety glasses. That’s cool. Complete with a three-year warranty against machine construction, this Efcut C30 Mini Wood Chipper is a great workhorse for your landscaping.

  2. 2. Worx WG430 13 Amp Foldable Bladeless Electric Leaf Mulcher

    • Mulches up to 53 gallons of leaves per minute
    • Clean air motor cooling system
    • Bladeless cutting system uses string trimmer line to mulch leaves
    • Collection bag sold separately
    • Included string is a little weak
    • This unit creates significant dust when loading leaves into the chute

    While the Worx WG430 Foldable Electric Leaf Mulcher isn’t a “wood chipper” per se, almost all of the wood chippers I reviewed featured questions from potential users regarding the shredder’s ability to mulch leaves. The answer, almost universally, is no unless the leaves are bone dry which, at least here in the Pacific Northwest where I live, almost never happens. I’ve got two large maple trees that drop an enormous amount of leaves each and every year that never fit into our yard waste container.

    Thank goodness for this little machine; this mulcher will transform eleven bags of leaves and debris into just one using a 13 Amp electric motor. This thing can mulch up to 53 gallons of leaves per minute with a 13-inch cutting diameter. It works (pun intended) by way of a large string trimmer head that whirls around to slash whatever you feed into it. It’s basically a large, string trimmer in reverse.

    The motor spins at 8,500 RPM that will reduce your dead leaves and twigs to 1/11th of its original size. The Worx WG430 Leaf Mulcher features an oversized mouth so, at that speed and power, you can pulverize them into manageable mulch mounds in no time at all. Leaf mulch will increase water retention in the soil, reducing watering time and saving you money.

    At less than 20 pounds, this mulcher features a compact design, in which the disassembled parts nest neatly together for convenient off-season storage on a shelf in your shed or garage. Setup takes only a few minutes, with absolutely no additional tools required. It also features a dust-reducing clean-air motor cooling system. Air and mulched leaves are separated through an external cooling air intake and exhaust to significantly reduce dust generation.

    The Worx WG430 features a universal bag holder that accepts both paper and plastic bags. You may want to take a look at this reusable 26-gallon option from Worx to work with your mulcher. This next fall is going to be entirely different for me and those trees in my yard with this leaf mulcher!

  3. 3. SuperHandy 7 HP 212cc Mini Wood Chipper

    • Hook it up to the ATV and tow it where you need it
    • 7HP 212cc 4-stroke engine
    • Compact and easy to load or transport
    • Replacement blades may be difficult to find
    • Leaves and foilage are much more work to shred than branches
    • Included blades aren't of the highest quality

    The SuperHandy 7 HP 212cc Mini Wood Chipper design comes with a large hopper for chipping and shredding branches and limbs up to three inches in diameter. The chipper effectively mulches yard debris with a reduction ratio of 15:1 with an elongated top adjustable discharge chute. It is powered by a 7HP 212cc horizontal 4-stroke single-cylinder OHV gas-powered engine best fueled with 87+ unleaded gasoline (Note: ethanol is not recommended with this engine).

    The rotor turns at 3,600 RPM to handle those tree branches easily. Limbs are no problem but understand that this chipper is made for them and not necessarily leaves and brush, especially when they’re wet. The hopper is large enough to get multiple tree trimmings at once to the blades while the discharge chute is adjustable so you can make that pile of mulch where you need it.

    The SuperHandy has the ability to towed with an ATV, riding lawn mower, or small tractor for easy transportation where you need it (Tow Bar Kit sold separately). This wood chipper comes with a three-year limited warranty as well. One final note: make sure that you fill and check the engine oil before use and frequently while using.

  4. 4. GreatCircleUSA 212cc Heavy-Duty Wood Chipper

    • Top hopper for brush and leaves, side three-inch tube for large tree limbs
    • The engine is crazy strong
    • Much quieter than other similar-sized chippers
    • Drawstring collection bag has trouble staying attached to chipper
    • Spark plug cap is directly below hot exhaust shield
    • Many reports of shipping damage

    Here’s the quick review: the GreatCircleUSA 212cc Heavy-Duty Wood Chipper runs great and is a superb size for any yardwork clearing job short of large acreage with downed trees. GreatCircleUSA has effective customer service and although there are reports of wood chipper damage during shipment, they’ve taken care of just about every problem that I read about. This is a tough yard maintenance tool that won’t let you down.

    Okay, here are some more details:

    The GreatCircleUSA 212cc Heavy-Duty Wood Chipper is powered by a reliable recoil-starting 7 HP 212cc horizontal four-stroke single cylinder OHV gas-powered engine that can handle yard debris of up to three inches in diameter with absolutely no problem whatsoever. This machine will immediately mulch rugged branches, limbs, and brush with little to no effort. Reduction ratio is around 15:1 so not too fine, not too chunky.

    This wood chipper has four Y-hammers that destroy branches and two steel chipping blades that truly shred what you feed them. The loading hopper o top is meant for leaves, brush, and small debris; the side chute is for limb chipping of pieces up to three inches. GreatCircleUSA sells a Universal Vacuum Kit (sold separately) for leaf mulching. This kit attaches easily on the backside leaf inlet to suck up leaves and debris with ease (there are also some creative ways I found online to get this done on the cheap with a little DIY ingenuity).

    You can also hook the wood chipper to your own personal ATV or lawn mower/tractor for easy transportation where you need it with this Tow Bar Kit (also sold separately). The chipper comes with a discharge bag for wood chips and mulch collection however it uses a drawstring closure making it difficult to secure.

    The GreatCircleUSA 212cc Heavy-Duty Wood Chipper comes with a three-year limited warranty and the dedicated customer support team will back that up. This is the third chipper that I’ve reviewed that doesn’t come with oil already added to the motor so I guess that’s the standard with gas-powered machines; remember to check and add before use.

    • Produces less dust than other mulchers
    • Excellent bag to housing connection
    • Works well with wet and dry leaves

It’s lightweight, compact, and has no attachments or tools to switch to get from blowing leaves to vacuuming them up. Simply turn the dial and you’re on your way.

    The Worx TRIVAC features a 12 Amp electric motor that delivers the power of a gas-powered engine while remaining ergonomic enough to operate with one hand. The angled nose and comfort grip handle will save time and make your yard cleanup a lot easier. In vacuum mode, the tube design provides 350 CFM (Cubic Feet per Minute) of suction power even when reaching under decks and patio furniture. The airspeed in blower mode can be adjusted from 75 to 210 MPH depending on what power you need.

    A quick tube release makes cleaning a breeze. When you’re ready to empty the included 10-gallon collection bag, hit the quick-release button to open up the unit.

  8. 8. Flowtron LE-900 Electric Leaf Shredder

    • Quick mulching action
    • Excellent shredding ability
    • Easy to use
    • Difficult to assemble
    • Messy and loud
    • Takes up more storage space than other shredders

    The Flowtron LE-900 Electric Leaf Shredder is an excellent shredder that really does just one thing: slice up your leaves into fine mulch. It can handle pine needles like a monster but watch that you separate out larger sticks and pinecones. The LE-900 works well using the included stand to mulch right where you need it or you place it directly on top of a trash can. The ability to firmly attach plastic trash bags underneath is also a nice touch.

    This shredder weighs around 17 pounds which isn’t the lightest of the shredders on our list but isn’t the heaviest, either. The operation couldn’t be simpler: place where you want it, plug it in, and begin throwing debris into the chute. That’s it. The Flowtron is a rugged machine with a funnel and housing made of high-density polyethylene with the capacity to reduce 11 bags of leaves to one.

    The Flowtron uses a patented double cutting line design for more reliable and effective mulching. The mulching level may be adjusted between needles, leaves, and clippings so the shredder keeps up for what you need it to. 



  9. 9. Landworks 7HP 212cc Gas-Powered Mini Wood Chipper

    • Chips branches up to three inches in diameter
    • Large 10-inch wheels and the ability to tow make transport easy
    • Economical solution for medium-duty chipping needs
    • Auto feed of branches can stall motor
    • Wheels are hard plastic and sort of cheap
    • Make sure you fill the oil reservoir; not included

    The Landworks 7HP 212cc Gas-Powered Mini Wood Chipper features the ability to chip and shred branches, limb, and yard debris up to three inches in diameter. The reduction ratio is 15:1 with an elongated top adjustable discharge chute. Not bad for this small of a unit.

    This wood chipper is powered by a 7HP 212cc 4-stroke single cylinder gas-powered engine. Keep in mind that ethanol is not recommended for this machine. The engine is about as basic a gas setup as there is with a manual choke, throttle, power switch, gas shut-off, etc. You’ll need to fill the oil reservoir yourself as it’s not shipped with any oil.

    This wood chipper is a solid performer. The feed bin and discharge chute are all metal with a thick coat of paint. Blades are supremely sharp and will whittle down anything you throw at it up to a three-inch diameter. Leaves and brush aren’t mulched as effectively as dry, seasoned sticks and branches. The motor also has a problem stalling if branches are simply thrown in the feed bin; this is resolved when they are gently fed.

    The Landworks Mini Wood Chipper features a handle and 10-inch hard plastic wheels for portability. A tow bar kit is available (sold separately) so you can hook it up to an ATV or small lawn mower or tractor and take the wood chipper where you need it. 

    This wood chipper comes with a three-year limited warranty and Landworks features a no-hassle customer service department. The Landworks 7HP 212cc Gas-Powered Mini Wood Chipper is a great little shredder to use around your yard and acreage.

  10. 10. Black & Decker BV6000 Blower/Vac/Mulcher

    • Inexpensive
    • High-impact metal fan
    • Two speed selections
    • Don't trip on the extension cord
    • Speed isn't variable
    • Wet leaves will clog vacuum tube

    The Black+Decker BV6000 Blower/Vac/Mulcher offers up three tools in one to manage all those leaves you must clean up before the snow hits. This leaf mulcher features a 250 MPH blower that plows through leaves and debris with ease. The high-impact metal fan prevents clogging while you’re mulching and is capable of grinding up to 16 bags of mulch down to just one.

    There are two speed selections; one for flower beds and one powerful enough for thick matted leaves. The 12 Amp motor gives some giddy-up and go to power the blower, vacuum, and mulcher so you can get that yard cleaned up. Changing between vacuum and blower settings happens in seconds with no tools to worry about.

    The reusable leaf bag design saves time and effort and is ideal for clearing driveways, sidewalks, decks, and garages of everything falling down from the trees. The vacuum is heavy-duty and great for vacuuming leaves, grass clippings, twigs, and pine needles. The BV6000 comes with the BV5600 Motor Head, a diffuser for use with disposable bags, a detachable shoulder strap, concentrator, blow tube, vacuum tube, and the reusable bag assembly. 

  11. 11. Earthquake K32 Viper 212cc Heavy-Duty Wood Chipper

    • Includes rugged debris collection bag
    • Five-year limited warranty
    • Features branch hopper and debris chute
    • Like other shredders, it doesn't handle wet leaves very well
    • Difficult assembly because of unclear instructions
    • Branch hopper opening is small and can't handle forked branches

    The Earthquake K32 Viper Heavy-Duty Wood Chipper features a compact, portable design and is ideal for turning your trimmed and fallen tree branches into nutritious mulch for your beds. The handlebar is angled such that the center of gravity is directly above the wheels for stability during transport. Storing it away until needed doesn’t take up much space in the garage because of the compact footprint.

    The 11-inch wheels on the Earthquake are large enough to tackle ruts and grooves on your way to the worksite however the wheels are the no-flat variety so transport may be a lot bumpier. The hopper is made of steel and designed to feed plant matter into the grinding chamber without much fuss. It should withstand the bangs and bumps that will result from large limbs.

    The tri and j-hammers in the grinding chamber should reduce the size of the resulting mulch drastically. This chipper is strong enough to power through branches as large as three inches around as well as leaves and twigs. Many chipper shredders don’t include a debris bag but the Earthquake does and with features such as a bottom zipper, rugged fabric carrying handles, and a docking bag connector that allows secure connection securely and quick removal.

    The Earthquake K32 Viper Heavy-Duty Wood Chipper is a solid machine that will make your yard clean-up a lot more fun. If you want to make things even easier, consider this universal leaf vacuum kit to suck everything up at the end of your chipping run.

Are Leaf Shredders Worth It? 

The short answer is that leaf shredders are definitely worth it. Any yard with trees is going to be littered with leaves at some point during the year. Raking, bagging, and disposing of leaves is a major chore. These mulching machines will save you time and hassle every single year. 

If you dispose of the leaves at your local landfill or county composting center, this can be a huge problem even if you own a pickup or truck. Bagging leaves is definitely not a fun job and it’s wasteful when using plastic bags.

If you compost, bravo to you! Composting at home is a great solution to waste and a real boon to your plants. However, whole leaves take up an enormous amount of space. There’s not much chance anyone has a compost bin large enough to hold leaves from just one tree.

Leaf shredders and mulchers turn enormous piles of leaves and needles into a fraction of their original size, decreasing it by as much as a ratio of 16 to 1. Mulchers make the leaves more ready for composting by increasing the surface area of the leaves. That makes things easier for beneficial microorganisms to digest the material and turn it all into rich compost that can be tilled back into your soil.

How Does A Leaf Shredder Work?

Leaf shredders can take one of three types: electric, gasoline, or handheld.

Electric shredders use string trimmer lines, much like weed eaters, to rip apart the leaves. Thick plastic strings spin at a high speed around a central motor housing to chop the leaves into small pieces. This type of shredder works best on dry, brittle leaves. 

A couple of drawbacks with electric mulchers is that you’ll need an electric outlet to plug into. If portability is necessary, this type of shredder may not work for you. Also be careful not to toss sticks, pinecones, or rocks into the hopper, or else you’ll break the strings fairly easily.

Gas-powered shredders use heavy-duty metal blades and grinding plates to tear material apart. Another name for these sorts of mulchers is wood chipper. These can usually handle large sticks and branches, anywhere from one to three inches in diameter.

They’re big and bad and can handle most anything however they’re also typically large in size and they can get expensive. If you have a forest in your backyard, a gas-powered mulcher might be worth it to you.

Both electric and gas-powered mulchers are stationary with a chute, also called a hopper, on top of the unit where the leaves and debris are deposited. Some models come packaged with a bag or bin to catch the fragments or will feature a way to secure a paper or plastic bag for collection. Larger gas units will feature an output chute that will spray the resulting mulch wherever you want it.

Handheld shredders are combination tools that feature a leaf blower, leaf vacuum, and leaf shredder in one. These utilize a metal impeller that looks much like a fan blade but with a solid back. When the tool is in vacuum mode, the impeller spins and mulches the leaves as they pass through the channel and into a collection bag or bin. 

If you truly hate raking (who doesn’t?), consider picking up one of these. They come in corded and cordless varieties. Keep in mind that they’re usually reserved for smaller yards, smaller piles, and shorter work periods. If you have loads of trees, a handheld shredder probably won’t work for you.

Handheld shredders strap on to your back or feature a shoulder strap and have a collection bag that will catch the shredded leaves. With these models, you either walk around the property vacuuming up the leaves as you go or you can blow them into a big pile and then vacuum them all up at once. 

Do You Have to Shred Leaves for Compost?

If you wish to make good compost, then shredding your leaves should be mandatory on your fall to-do list. Whole leaves will eventually decay and turn into compost for your beds however breaking down leaves into tiny bits will speed up the process exponentially. As the microorganisms feed and divide, smaller chunks of debris will quicken their ability to turn your yard waste into nutrient-rich compost.

What kind of leaves you have for shredding will determine whether they’re good for your compost pile. Maple, birch, ash, beech, cherry, and any sort of fruit and nut trees are excellent choices for turning into fertilizer. They decompose quickly and provide a balanced nutrient mix.

Trees with tough, waxy leaves (I’m looking at you, magnolia tree) will eventually break down but it may take years. Oak leaves are acidic and should only be used in combination with other tree leaves up to 20 percent. Black walnut and eucalyptus leaves contain natural herbicides that may prevent seeds from germinating so be careful with these.

A good rule of thumb when shredding and composting your leaves and other mulch is a five to one ratio between brown material (leaves) and green (fresh lawn clippings and plant material). Compost piles require oxygen which can be introduced when turning over your pile every few days. 

They also need moisture and nitrogen which comes from that green portion of the pile and can take the form of vegetable scraps, coffee grounds, and eggshells. If you have farm animals such as chickens, horses, cows, or even rabbits, their manure can quickly accelerate the decomposition process...just plug your nose and let nature do her thing. By the way, keep your average pet droppings out of your bin.

There is one more factor to consider while planning your fall yard care: many species of beneficial moths, including beautiful Luna moths and Promethea moths, build their cocoons inside of fallen leaves. This means that the piles of leaves you rake, and potentially shred, could contain moth caterpillars wintering inside of the leaf rubble. 

It is definitely possible to learn to identify moth cocoons among the fallen leaves and to save them if you wish. Another option is to set aside some of your fallen leaves to use as a ground cover around trees, shrubs, or temperature-sensitive garden areas. This will give the moths a chance to survive the winter while protecting your plants much like standard mulch would.
