Description
The Earthquake Chipper Shredder K33 features a compact, portable design and is the ideal height for operation, the right geometry for easy transport, and compact for efficient storage. The unit stands 34” tall, so there is no need to lift material over your head. The handlebar is angled to put the center of gravity directly above the wheels for stability during transport. The compact, square shape of the unit gives it a small footprint in the garage. The 11” airless wheels allow the chipper shredder to be moved easily over roots, ruts and other uneven terrain. Thanks to the airless design of the wheels, you will never have to worry about a flat tire on your chipper shredder. Made with tough, durable components, the Earthquake K33 is made to last. The rugged steel hopper is designed to efficiently feed plant matter into the grinding chamber and to withstand the bangs and bumps that occur when working with large limbs. Also, in the grinding chamber the tri- and j-hammers will reduce material 20:1. This chipper shredder is strong enough to power through 3” diameter branches and masses of leaves and twigs. Earthquake not only includes a debris bag as standard equipment; it also has features not seen elsewhere that make it the easiest bag to use in the industry. Among its features are a Bottom-Out zipper, rugged fabric handles for carrying, and a Dock-and-Lock bag connector that allows you to connect your bag to the unit securely and remove it quickly. Check out the optional Earthquake Chipper Shredder Vacuum kit and Tow Bar (both sold separately) for additional chore tackling equipment.

If it fits, it chips
Style: Chipper Shredder K33 - 301cc
I went looking for the best wood chipper I could afford with my limited budget, and selected the Earthquake K33 after weighing several variables. I am in no way disappointed with my choice. It's not a Vermeer, but for a limited, budget chipper, I would have settled for less than I got with this purchase. I think it's a good value for the money. It has less capacity than some chippers at this price point, and it also has more power relative to the capacity it does have. It should be strong and capable, within the limits of what it can do. If it fits, it chips. I was honestly expecting more of a struggle to peck my way through some of the more challenging pieces I needed to chip. Nope. For the most part, this machine just sucks the wood in, and spits out chips. While its ability is severely limited, it does have some ability to suck in branches complete with side shoots. You don't have to trim away every single lateral branch to get something to feed. At least not with fresh, green pine. The bag attachment is convenient, and it works well. When the machine starts to get "wood chip reflux" and starts burping chips out the feed opening, that's your clue that it's time to go dump the bag. It just takes a minute or so. I didn't think I would like the bag, and I originally tried running it without the bag attached. With no bag, it blasts chips out hard enough to rip up your grass, and they go everywhere. It's probably pretty dangerous, too, which is why there are strongly worded warnings about not doing that. It turns out that it's not worth doing that anyway. The bag provides an efficient way of directing the chips into a yard cart or whatever, and it holds just about as much of a load as I would want to heft and dump. It's quite manageable as is, and I would not want a bigger bag. Assembly took about 30 minutes, and it was pretty obvious how to fit everything together. The instructions were incomplete as far as what sizes of wrench I would need, but that's not worth a star. I've read other reviews that complained that the unit did not ship with enough oil, and I also found that to be the case. The supplied oil was enough to get the level up to the add mark. I had to add significantly more to get it up to the full mark. The unit was rather hard to start the first time, and it has continued to be quite hard to start. This is a pretty big engine for a pull start, but if you work at it, you can coax the thing to life eventually. It's not as bad as that '60s era pull start riding mower my parents had when I was a kid, but it's definitely the worst pull start machine I've experienced since The Beast. I'm not 16 anymore, so I'm glad it's not quite as hard to start as The Beast. Still, it's pretty bad. I won't lie about that. You need some upper body strength to get this thing fired up. It's a lot of engine for a recoil starter. Once it gets running, it's not as loud as I was expecting. Fuel economy also exceeded my expectations. I pretty much planned to have to top off the gas tank every little bit, but so far, I've done about 70% of the wood I needed to chip, and I haven't run out of gas yet. I processed some old, dry hardwood branches, and a lot of fresh, green pine. The machine chewed through both with gusto. I managed to stall it out exactly twice. The first time was an old, dry, hardwood branch about 2" in diameter and about 10' long. I expected to have to peck away at the branch, but the machine just grabbed it, and sucked it in all the way to the end. It sucked it in so fast that it bit off more than it could chew, and stalled out on the last little bit. I didn't have to clear that jam. I just emptied the bag, restarted, and continued. The second time it stalled, I took a long pine branch that was near max capacity, and whittled on it with a hatchet where there were branch clusters I didn't expect to pass through. I fed the branch short end first, and kind of expected the machine to reject the last couple feet of this branch as too much of a meal. To my surprise, the machine sucked it all in, all the way to the very end. The fat end was a little too much of a meal for the Earthquake, and the machine stalled out and jammed hard. That time, restarting it wasn't an option, because it was impossible to turn the engine with the pull cord. Clearing the jam was a simple matter of removing three bolts with a 13mm socket, then poking around in there to loosen things up. It wasn't an unreasonable amount of effort, and it wouldn't have been necessary if I hadn't pushed things as far as I did. One bolt has fallen out and gotten lost so far. It was one of the bolts holding the cover over the recoil rope. It's just gone. Vibrated out and lost, apparently. Meh. I should probably contact the manufacturer about procuring a replacement for that, but it's not a high priority. The machine has exceeded my expectations so far. If this machine lasts enough seasons, it will eventually pay for itself in the money I save on gas and dump fees. It's also better to turn all the trimmings into something useful than to chuck them into a landfill. I'm a native plant gardener who turned a nice suburban grass patch into something more like a forest, and over time, these wood chips will break down and make my nice black humus even more rich.

This works great
Style: Chipper Shredder K33 - 301cc
So my first review stated it was damaged when it arrived. They sent the damaged hopper but did not have the part in the right color.... Now that I have used it over the past few weeks, I am impressed at how well it works. I had a Troy Built in the past that was always a struggle to start and feed. This one starts everytime on the first pull. It gets a little bogged down with long 3 inch lengths so I just listen for the strain and pull the peice out of the blades for a few seconds and it continues to work like an animal. The mulcher guard does not open and close easily, so sad to say I have to leave it open. Compared to my past machine, this one is a 5 star.

Great machine; waiting to see if Earthquake will fix broken weld
Style: Chipper Shredder K33 - 301cc
I have owned this machine almost two months and have used it approximately 20 hours. It is a real workhouse. Assembly was slightly complicated by the fact that the flange bolts were missing--but I could use other bolts provided for some of the packing material as almost identical replacements. BUT some of the welds holding the flanges for attaching the hopper to the shredder are breaking. I am writing to Earthquake to see about a fix. I'm a little nervous though because when I put the machine together I was never able to register my purchase for the warranty. I could get to the site. Then I would get a message to try again later. I finally gave up. Fingers crossed. UPDATE: Within 24 hours of filing my warrantee claim, I received an email that a new hopper is on its way. Very fast and friendly service. I'm leaving my review at 4 stars, though, because the weld on the hopper seems to be a common problem, the instructions are not easy to decipher, and I had to jerry-rig some other bolts to attach the hopper because it was missing 8 bolts when it arrived. Nevertheless, excellent machine. Worth the trouble, especially given the great service.

works as advertised , but
Style: Chipper Shredder K33 - 301cc
Manufacturer might not realize that at this price range it is not a professional that uses it , and instructions could be much improved , for a simple gardener might struggle with it . However , it works and it works well Pro(love it , if not for the cons I would give it 5+ stars ): 1. it takes branches much bigger then I expected , takes it relatively easy 2. it mulches much better ( smaller and more split ) then the normal bug of mulch from Home Depot, which makes it much better mulch and it will disintegrate much better and it will retain water much better , that is a HUGE plus to an organic gardener 3. it gas consumption is reasonable 4. bug size is big , and it is an equivalent of two off the shelf bugs of mulch , 3 bugs if you consider better consistency Con: 1. Instructions are cryptic and might as well be a puzzle 2. because of the #1 assembly is not straight forward 3. The starting this thing is often problematic , it is somewhat capricious, especially for a person who never worked with combustion engines of this type 4. rubber safety strips are not very effective , chips are flying out , glasses and industrial gloves are not just a safety precautions , they are necessity, must have Knifes need replacement(at max 15 days usage ) , manufacturer no longer sells it

Excellent Chipper, but labor intensive.
Style: Chipper Shredder K33 - 301cc
Be prepared to spend some time assembling this machine with an open end wrench. Fastener locations don't allow access with a ratchet and socket. The unit is heavy and very difficult to get out of the Styrofoam to install the wheels. Once assembled, it was very difficult to get loose leaves and twigs to push past the rubber fingers protecting the opening in the hopper. I had to hand feed everything through the chipper chute. I'm not sure how to get loose material to bypass the rubber finger guards in the hopper without removing the rubber fingers. The 20:1 reduction rate turned 2 very large piles of twigs and leaves into a single bag of mulch.

Results may vary
Style: Chipper Shredder K33 - 301cc
I would give this a higher rating but the company pissed me off initially when it was supposed to be delivered in a week and ended up taking 3 weeks just to ship. Instructions weren't incredibly clear or detailed. Finding the right washers for build-up was a little misleading. The leather straps that go into the hopper aren't listed in the instructions. As far as operation goes, the shredder portion on top works great and eats everything the right size range that I feed it. The chipper is a bit of a let down. Manual says 3" but if that wood is properly seasoned it'll be far too much of a pain to use. Very wet or overly dry works pretty well, but if it would make good firewood it should be disposed of as such. A nice additional tool to add would be something to help push stubborn logs down the shoot. I found the perfect sized branch to do so but not everyone can get as lucky as I did.
