Chipper shredders are landscaping tools that grind up branches, leaves, and other dry organic debris. Shredding this waste material reduces the volume, making it easier to haul away or, better yet, reuse around the yard. The resulting chips can be used as mulch on a flower bed to keep weeds at bay or added to a compost pile to create a rich, dark compost that will improve the soil quality. We tested three chipper shredders on a mountain of pruned branches, dried sunflower stalks, and assorted garden debris. Each tool proved capable of doing the job, but they all came with their own pros and cons relative to power, performance, and price.
Our top choice, the Earthquake K33 Gas Chipper Shredder, boasts a powerful, easy-to-start 301 cubic centimeter (cc) gas engine with ample chipping power and a low hopper rim that makes it easy to load for hours on end, if necessary. Additionally, we highlight a range of top models that feature towing hitches, larger chipping capacity, and electric motors in this guide. Read on to learn more about these handy machines and choose among the best chipper shredders for your yard—and your budget.

Our Top Picks
To qualify as a top pick, a chipper shredder must be powerful enough to shred dry yard waste, safe and easy to operate, and durable enough to provide years of service. Shredding needs vary, but the following machines will suit a variety of needs. Keep reading to discover some of the best chipper shredders on the market today.
Best Overall
Earthquake 301cc Gas Chipper Shredder
Our Ratings: Assembly 4/5; Ease of Use 5/5; Performance 5/5; Noise 4/5; Value 4.7/5
Product Specs
- Type: Gas-powered
- Feed type: Manual feed/gravity feed
- Maximum intake diameter: 3 inches
What We Like
- Powerful engine chews through branches without bogging
- Large wheels roll smoothly over rough ground
- Low hopper rim makes it easy to load
- Includes dock and lock bagger attachment
What We Don’t Like
- Twice the price of some similarly equipped models
The Earthquake K33 chipper shredder provided everything we needed for routine and occasional heavy-duty yard work. Packing a dual-knife chipper disc and a 301cc gas engine that produces 13 foot-pounds of torque, it possesses the power to chip branches up to 3 inches thick without hesitation. On the other side of the machine, four shredding hammer assemblies make quick work of twigs, leaves, pine cones, and other fine garden waste.
We were impressed by the Earthquake K33 chipper shredder from start to finish. The engine started on the first pull of the recoil cord. We alternated feeding tough, dried hardwood branches and freshly pruned green wood into the branch chute, up to the full 3-inch thickness specification. At no time did the engine stall, and it only slowed a few times.
The hopper produced similar results. At one point, we dumped an entire bushel basket of pine cones and dried leaves into the hopper all at once, but it tore right through them and filled the collection bag tightly, without the need to clear clogs from the discharge chute. The collection bag also earned high praise, as it simply twist-locks onto a receiver on the discharge opening for quick attachment and removal.
Although it costs several hundred dollars more than some other compact gas-powered chipper shredders, we felt the performance warranted the premium price. The Earthquake K33 would make a smart choice for frequent use on larger properties.
What our tester says: “Operating the Earthquake K33 was very gratifying. The engine was super easy to start, and it had more than enough power to chew through any branch that would fit in its chute.”

Best Bang for the Buck
SuperHandy Wood Chipper Shredder Mulcher
Our Ratings: Assembly 4/5; Ease of Use 4.5/5; Performance 4.7/5; Noise 4/5; Value 5/5
Product Specs
- Type: Gas-powered
- Feed type: Manual feed/gravity feed
- Maximum intake diameter: 3 inches
What We Like
- Affordable gas-powered chipper shredder
- Lightweight and compact; easy to transport and store
- 212cc gas engine for frequent medium-duty yard cleanup
- Simple startup and operation
What We Don’t Like
- Engine occasionally stalls when encountering tough material
- Discharge chute may clog on excess chips
There is no need to exceed your budget on a heavy-duty tool for infrequent use. The SuperHandy chipper shredder sells for a fraction of the price of our Best Overall pick but delivers reliable power and performance for frequent medium-duty yard work, such as green wood branches up to 3 inches thick, dry leaves, pine cones, and twigs.
We assembled the SuperHandy chipper shredder in about 45 minutes. The kit did not include engine oil, so be prepared with a quart of 10W-30 for year-round use. The engine started on the second pull and started thereafter on the first or second pull every time.
This machine includes a collection bag supported from above by a steel spreader rod. The spreader holds the bag up, allowing the chips to begin filling at the far end of the bag. The setup worked fairly well, but the airflow was not strong enough to pack the bag tightly.
A couple of operational notes distinguish the mid-level power of this unit from our Best Overall pick. To avoid clogging, the hopper required a steady, moderate flow of leaves and pine cones. Sometimes twigs blocked the flow to the shredder head, so we kept a push stick nearby. When it came to dried hardwood branches, this unit maxed out at about 2 inches thick, as anything thicker was likely to cause the machine to stall. With that being said, the SuperHandy chipper shredder is an excellent value for disposing of freshly pruned branches, fallen leaves, and the like.

Best Electric
Wen 41121 Rolling Electric Wood Chipper and Shredder
Our Ratings: Assembly 5/5; Ease of Use 4.5/5; Performance 4/5; Noise 5/5; Value 4.7/5
Product Specs
- Type: Electric
- Feed type: Manual feed
- Maximum intake diameter: 1.5 inches
What We Like
- Lightweight and compact; easy to store and transport
- Budget-friendly price
- Does not require gasoline
- Ideal for small spaces or occasional use
What We Don’t Like
- Not practical for shredding leaves or other fine debris
- Slower and less powerful than gas chipper shredders
For smaller properties and those who want to save money on yard cleanup, the Wen electric wood chipper and shredder could be an ideal choice. This budget-friendly machine features a strong 15-amp electric motor that drives up to 8,000 cuts per minute. As a light-duty chipper shredder, it is not suitable for clearing fallen trees or major storm cleanup but accepts branches up to 1.5 inches thick and produces usable mulch for the yard or garden. The compact, upright design makes it easy to store in smaller spaces.
Our best electric chipper shredder had the lowest price among all the models in this guide. It was fast and easy to set up and did a great job on the small stuff. Assembly and startup took about 15 minutes, and all the necessary tools were included. Weighing just 23 pounds, the machine is very lightweight but stable while in use. The chips it produced were similarly sized to those from the gas chipper shredders, so they were useful for either mulching or composting.
Larger property owners—and those with piles of bigger branches—will be underwhelmed by this machine. It worked more slowly than the gas-powered chipper shredders in this guide. The narrow opening was too small to insert leaves efficiently, and the 1.5-inch maximum branch size limited practical usage to (mostly) the smaller branches you might prune during spring yard maintenance. If a storm blows down a tree, or a big branch falls, this model probably won’t cut it.
What our tester says: “Unlike big heavy gas models, the lightweight Wen electric chipper makes it easy to grind up the smaller branches that I often prune on a whim because they knock off my hat while I’m mowing. It’s super convenient.”

What We Don’t Like
- Requires more physical strength to start and operate
Residents of wooded properties might consider investing in the DK2 gas-powered commercial chipper shredder. It is equipped with a 429cc Kohler Command Pro gas engine to take on the big branches. This heavy-duty tree shredder can chew branches up to 6.25 inches in diameter and features a self-feeding side chute that grabs branches and pulls them into the spinning blades.

How We Chose and Tested the Best Chipper Shredders
We researched the most sought-after chipper shredders in their respective categories and discovered that the best models are determined by their type, feed type, intake diameter, chute options, towing ability, and other special features included by top brands. After extensive product research, we included options in our list of top picks that were gas- and electricity-powered with manual, gravity-feeding, and vacuum designs. For testing, we decided to include both premium and budget-friendly models.
We referred to product specifications as well as our own observations to evaluate the three chipper shredders we tested. The process included assembling the machines, transporting them 400 feet across the yard to the work site, and using each one long enough to fill two bushel baskets with shredded landscape debris. After working with each model, we recorded our notes on a scoring rubric. Then we compared the specs of the models we tested with the models we didn’t test to ensure that our recommendations were as useful as possible.
What to Consider When Choosing a Chipper Shredder
For one-time use, you might consider renting a chipper shredder, but property owners who have trees often find it more convenient to own one. These machines range in price from around $100 for a lightweight electric model to several thousand dollars for a heavy-duty gas-powered machine. The best chipper shredder option for a given user will depend on the type and amount of debris they plan to shred.
Types of Chipper Shredders
Chipper shredders are available in two main types: electric and gasoline-powered, with each being suited to different chipping and shredding needs.
Electric
Mainly designed for small yards and light use, electric chipper shredders require plugging in with a heavy-duty 12- or 14-gauge exterior extension cord and can usually grind dry leaves and small branches up to about 1.25 inches in diameter. These backyard power tools are relatively small: about 2 feet wide by 2 feet deep and 3 to 4 feet high. Many come with wheels for mobility. The upside to these models is that there is no gasoline to mix, no toxic fumes, and no fuel to store. The downside to electric models is that users are limited to the length of an extension cord, so they may have to bring the yard debris to the chipper shredder via a wheelbarrow.
Gasoline
Gasoline-powered chipper shredders make quick work of yard cleanup by grinding twigs, leaves, and even small branches up to 6 inches in diameter. Because they’re not tethered to an electrical outlet, users can take them wherever needed, and they typically feature wheels for maneuvering. Some larger models come permanently mounted on a trailer with a hitch that allows the user to pull the machine with a pickup truck or lawn tractor.
Power Take-Off
Available for farm use or commercial mulch production, some large chipper shredders run off the power of another piece of equipment via a power take-off (PTO). The most common PTO source is the rotating spindle of a tractor, but some trucks and other large vehicles come with PTOs, allowing users to connect a large implement, such as a commercial chipper shredder.
Yard Size and Debris
In general, a small yard is better suited to an electric chipper shredder than a large yard, but this is not absolute. A small wooded lot can produce more twigs and yard waste than a large lot with just a few trees. A better way to choose which type of chipper shredder is best for your needs is to consider how much debris the yard produces. For instance, a gas-powered model may be the better choice for a large garden whose owner needs to shred bushels of dry organic stalks, twigs, and limbs. However, if there are no more than a few wheelbarrows of debris to clean away in the autumn, users could probably get by with an electric model.
Hopper/Feed Chute
To keep fingers a safe distance away from a shredder’s sharp blades, these machines feature long chutes, also called hoppers, into which the user inserts twigs and sticks. Some chipper shredders feature a single-loading chute, while others have two chutes—one for branches and one for smaller yard waste.
- Manual feed: On a manual-feed chipper shredder, the user pushes branches and limbs into the machine’s spinning blades. The spinning blade motion may help pull the branches into the blades slightly, but the user must maintain pressure.
- Self-feed: A self-feed chipper shredder features rollers inside the chute that actively pull branches and debris into the spinning blades. The user can load the branches into the chute and then gather more while the machine is grinding away.
- Gravity feed: Sometimes called a drop-in chute, a gravity-feed chipper shredder features a flared opening at the top of the machine. The user loads twigs and debris, and gravity helps them work their way into the spinning knives.
- Horizontal chute: A horizontal chute sticks out sideways with an upward tilt of about 45 degrees so the user can feed in debris from the side. The upward tilt keeps leaves and small twigs from falling out.
Reduction Ratio
The amount to which a chipper shredder will reduce debris is known as its reduction ratio. This number appears in the product’s description as a numerical ratio, such as 12:1. For example, if users purchase a chipper shredder with a 12:1 reduction ratio, it will reduce the amount of raw waste from 12 buckets or wheelbarrows to a single bucket or wheelbarrow. Average reduction ratios range from around 10:1 to 17:1. The higher the ratio, the smaller the chips the machine will produce.
Additional Features
While chipper shredders are straightforward landscaping tools, some models include accessories that can make them easier to operate.
- Control system: Some self-feed chipper shredders feature sensors that automatically adjust the rate of the material being drawn into the spinning blades. This option is usually available only on commercial or prosumer models, but it helps keep debris from getting stuck in the chute if it’s fed in too quickly.
- Vacuum chipper shredders: This option uses suction to collect debris, so the user needn’t feed it into the chute. One type of vacuum chipper shredder resembles a standard lawn mower, but instead of cutting grass, it sucks up leaves and small twigs, grinds them, and then discards the shredded debris in a bag. A second type of vacuum chipper shredder is designed for pulling behind a lawn tractor. The difference between a lawn vacuum and a vacuum chipper shredder is that a lawn vacuum features suction only, while a vacuum shredder vacuums and actually grinds up the debris.
Maintenance
It’s essential to check both gas and electric chipper shredders before each use to ensure that no debris is stuck in the chute or blades and that the blades are moving freely. Gas models require additional maintenance, including periodically replacing spark plugs and the air filter, as well as changing the oil. Both types may need blade sharpening if the shredder starts working more slowly or fails to efficiently grind debris. Specific models may also require lubricating the chain, so consult the owner’s manual and stay up-to-date on maintenance tasks.
Safety Tips for Operating a Chipper Shredder
Chipper shredders are power tools, and as such, users must follow basic safety precautions during operation:
- Wear safety glasses to keep airborne debris out of the eyes.
- Wear hearing protection if running a powerful gas chipper shredder.
- Durable leather work gloves will protect the hands from pokes and scrapes when loading twigs and sharp items like rosebush stems into the shredder.
FAQs
If you’re in the market for a chipper shredder, you likely have some questions. Read on for answers that will help you shop wisely.
A chipper shredder is a landscaping tool that shreds dry wood and plant waste to be recycled as mulch or compost or simply discarded.
A reduction ratio indicates how much the chipper shredder will reduce the size of the twigs, branches, or other plant waste. For instance, if a chipper shredder features a 12:1 reduction ratio, it will reduce 12 bags of yard debris to just one bag.
First, load branches and other dry yard waste into the shredder’s intake chute(s). You can then collect the small chips in a bag for use in your garden or discard them.
The chips are ideal for use as mulch around the bottoms of trees and other plants to reduce weed growth and help keep moisture in the soil. You can also add them to your compost bin.
