Hi all!! This will be extensive but if you want to make your life easier when using this tool it will be a good worthwhile read, so get your coffee. This little tool is awesome as long as you use it for what it was made for. I had been looking around for something that could help me cut, mulch, chop or shred palm tree leaves or fronds. Any one that has palm trees knows that the leaves/fronds occupy a ton of space and, if you live in a dry area, take forever to disintegrate and if you live in a wet or high humidity area they will rot and kill anything under them and also kill the view of a nice back yard while rotting away. Contrary to wood they are fibrous and not really hard except for the ones from huge coconut trees. First, gloves and eye protection. Palm tree leaves/fronds will not kick around like branches but being safe is always a good habit. I started looking at reviews here and found that the SunJoe brand (unknown to me) had a small branch chopper. I wasn’t looking for something I would later have to build a shed nor was I planning on taking down an ancient redwood forest and this met the size and need. Once I received it I tried my luck with a few fronds but first I read and read and read reviews from those that had tried it for that purpose. My Dad would say, “learn from the experience of others so you don’t mess up as much in life”. Here are the pointers: Best use dry fronds, not that it would not do a great job with green ones but it does chop them up in a more complete manner if dry. The tool sort of chews the thinner green ones, but that is more related to how I adjusted the blade (I'll explain that later). In my case it sort of “pinches” the thinner parts ending up with some long flimsy pieces, still very manageable and easy to work with. I also recommend, if chopping green palm leaves, to have around a few very dry ones to pass through at the end of the job to pick up any humidity left on the blades and shaft. No idea what the blade is made of but the shaft is clearly hardened or tool steel and it will rust if set aside still wet or humid. I definitely don’t recommend the wet, rotty or soggy fronds. They make a mess that will need clearing out. This is also an easy task with only one required tool (I think it’s included but don’t quote me on that, I used my own). Another tidbit of info, the tool s recommended for branches no thicker than 1.73” but palm tree fronds tend to be wide and sort of flat so, as long as the frond is not wider than the cutting blade nor thicker than 1.73” you’re good to go. Also enter the frond flat side against the blade. I cut the frond end that connects to the tree off at about two or three inches into the stem and feed those in separately, if too wide I’ll cut them in half so they fit in. It will even chop the little branchy things that have the seeds if you cut the curve in half so it’s a little bit straighter. See the pics I’ve included of end results. I even tried it on the wide palm tree leaves that look like the fans, seen in the pics, the pharos used to have in Egypt. Some one that is creative can find a use for these scraps since they come out like small accordions. My best result was cutting the leaves in half, stem and all, along the grain/fibers. You end up with 2 palm tree leaves. These are more dense/ thicker and the motor complains even if it is a lot of empty space. About the cutting blade. The instructions say to adjust the blade until a few shards or metal scraping start to come out. I adjusted mine so that the blade barely touches the anvil or flat surface against which the blade cuts. I think that metal against metal will greatly reduce the life of the blade since it would actually be cutting the other metal surface, but then that me and how I did it. If cutting green ones I feed a few dry ones every three or four greens. That keeps it clean and it doesn’t clog up. Always watch the output vs. the input, if nothing comes out, it's clogged. Turn it off and unplug. Reach in from the output side and try to pull out the clog. It will usually just fall out. Plastic edges on the inside are not sharp but will scratch up your arm if you don't do it carefully. If you feed too many greens it will clog up, badly. No fear, use an allen wrench or hex key unscrew the for plated screws on the front plate (the black metal cover). If done correctly, the screws will stay on the lid. Carefully pull the lid off, don’t drop it, it seems cast and can crack or break. Then carefully pull the blade off, use leather gloves. The shaft has a keyway and key, keep this in mind when replacing the shaft. Clear all the scrap from the lid, shaft and blade. Replace all, don’t over tighten the screws, and you’re good to good. Sooner or later you will need to do this since even the dry leaves will have very thin parts that can creap into crevices. Mine did come with a slight damage on the black, plastic top cover, but it wasn’t a showstopper. I suppose that happened in the mail. The thing is heavy to lug around in a box and probably got dropped more than once. It will not chop regular tree leaves since the blades are oriented and cut in a manner that’s best for branches, again, not what it was made for. I also found that the bag is good for smaller jobs but in my case, I can chop 20-30 leaves at a time, not good I found a large flowerpot and used that but a rectangular tote is now doing the job. Another pointer, it’s cutting dry stuff so it will make a lot of dust. It’s also a tad bit loud so working in open spaces outdoors is best recommended. I tested mine with a dosimeter and it was below 80dB at my ear height so, unless you plan on using it for more than 4 hours straight I don’t think you’ll need ear plugs. Use it for what it was made for and it will pay for itself. Cheers!!! ... show more

    • Essential Replacement 'Wearing' Part seemingly NEVER Available
Style: Shredder
This is an honest review AFTER having dealt with 7 different Sun Joe customer service representatives by phone [on 7 different days spaced out over 4 months]. To start, I would like to state that I have been buying items on Amazon for over a decade now, and this is ONLY my 2nd negative review, so this should mean something. I purchased my wood chipper in December 2022. It worked well until April 2023, when its counter plate broke; this plate is an "essential replacement" part, since the machine will NOT function without it. Consequently, I went to Sun Joe's website and several others to order a replacement part. The part, itself, only cost $10.00, but it was "out of stock" everywhere I checked. Since I was still covered under Sun Joe's two-year warranty, I called Sun Joe [in April 2023]. They told me to wait for the part to come back in stock, that it should be available by summer, since the chipper is a summer product. After waiting until June 2023, the part was still out of stock, so I called Sun Joe again (2nd time). They again told me to wait for the part to come back in stock. At this point, I started reading negative reviews of the chipper on Amazon, on YouTube, and even on Sun Joe's own website. A very common complaint was that the replacement counter plate is never available; other customers wrote that they had been waiting for as long as 6 month to 1 year without it ever coming back in stock. Still, I continued waiting. In August 2023, I could wait no longer. By this point, not only was the counter plate STILL not in stock, neither was the chipper itself on any major website (Amazon, Home Depot, Walmart, etc.). Therefore, I called Sun Joe (3rd time) and requested that they honor my warranty. Since they had no idea when the part would ever come back in stock and could NOT ship me a replacement chipper of the same model, I asked for my money back. Since I purchased the product on Amazon (not on Sun Joe's website), I was told the best that they could do was store credit for their website, which was fine with me. To receive the store credit, I was told to ship the product back to their warehouse via UPS; Sun Joe provided a label. The [Sun Joe] representative instructed me to wait 48 hours after my shipment arrived to their warehouse before I would call them back. I tracked the shipment via a tracking number and 48 hours after it arrived to the warehouse, I called Sun Joe (4th phone call) for the store credit. The representative told me that I should have received an email with the store credit code by this point (I didn't, not even in my spam folder); something must have gone wrong. Sun Joe assured me that the email would come if I just waited another 48 hours. What did I do? I waited 48 hours again only for the email with the store credit to STILL not arrive. Thus, I called Sun Joe yet again (5th phone call). This newer representative told me that I should've waited 72 hours (3 days) instead of 48 hours for the credit to arrive. Anyhow, he assured me that if I would just wait another 48-72 hours, that I would receive the email with the store credit. So, I waited 72 hours this time only for the email with the store credit to STILL not arrive. How much patience can one client have? Keep in mind that Sun Joe had already received my broken chipper over a week ago by this point, and I was left with nothing (i.e., no replacement, no refund, no store credit). As a result, I called Sun Joe yet again (6th phone call). At this point, the representative finally called their accounting department on my behalf. Within hours, she called me back and had emailed me the store credit code. You would think that this would've been the end of my problems, right? Unfortunately, when I entered the store credit code [on Sun Joe's website] and purchased a different chipper, I was NEVER sent a confirmation email/receipt; it was not in my spam folder by the way. Had Sun Joe just "stolen" the store credit that they just provided to me [AFTER I had waited over a week for it]? How could I know that I hadn't been cheated, since Sun Joe's own website NEVER even provided me a tracking number upon purchase? Call me crazy, but I called Sun Joe a 7th time about this newest issue. The representative on the phone then sent me an email with an order number but NOT a tracking number. The only way I was able to finally obtain a UPS tracking number was because I contacted Sun Joe an 8th time; this [hopefully last?] time I used their website's chat feature. As of writing, I have not received the chipper I purchased with store credit. Will it ever arrive? Who knows? Even if I do get it, I don't feel Sun Joe can ever adequately reimburse me for my time that it has wasted, not to mention all of the frustration that I and its other customers have experienced. The only positives I can say about my aforementioned experience are the following: -The wood chipper worked well until it broke. (Reminder: Its counter plate breaks easily, and a replacement part is seemingly NEVER available; many other reviewers confirm this.) -The customer service representatives were available, polite, and professional, although not the most effective as evidenced by my experiences. -The customer service representatives all assured me that all of the issues I experienced AFTER I had shipped my broken product back to their warehouse were atypical and not indictative of how they would like to provide service. Nonetheless, the service I got was what I got = less than stellar. If there is one takeaway from my story, it's "Caution: Buyer Beware!" ... show more

I received this Monday, today is Friday and i know what your thinking "Bleh how can some on review something they had for a week?" well lets just say i got the big one for a reason, that reason being the 7 foot tall 20 foot diameter pile of brush in my back yard. Now i got this with the full understanding it WOULD NOT accommodate all of my needs And i gave it a Three Star rating because that how i feel "its Ok" is very apt a description. to start for just under 200$ delivered it has preformed well within my expectations. i am running it for up to 3 hours a day for the last 5 days and have not blow it up or seriously stalled it out. I am regularly maxing out on the size of what this can do and thus far it has manage to EVENTUALLY choke down every thing i can fit through the opening. with that in mind it does not always "chip or Shred" what goes through it. if you have very green wood or vines (such as grape vines) or things with stringy spongy bark it will "scrape" the wood off and spit out a ribbon of bark. Not all wood is equal. What i am mulching is a mixture of green wood cut recently, 1-2 year old punky rotten wood, seasoned cut and dried grape vines, hedge trimmings, and rose bushes that died and were ripped out. The "Chip" i get is very different according to density and size of what goes in. the hard grape vines tend to get "shaved" down by the rotary Hammer they call a blade (more on that later), the hard brittle rotten stuff gets either chunked into full crushed rounds about a half inch think and crumbling or crushed up into a splintery dusty mix you would expect "shred" to look like. Small twigs and pinky finger sized stuff is the only thing that is evenly chipped if it does not fall through intact. So consistency of the grind WILL vary greatly based on what it is. The mechanism. This is a LOW RPM, HIGH TORQUE, Rotary, horizontal grinder. it has one rotary blade that turns about 60-80 rpm max. this i believe is were it gets its noise reduction from. it is quiet enough to run in a neighborhood with out having to worry about noise but after a while if you are doing large quantities you will want some ear plugs. The base is sturdy enough and only shakes slightly when somewhat over taxed, For some insane reason the designers included two cup holders into the design. these are for display only and serve no functional value except to collect small sample of your trimmings for later review...avoid using them to hold any thing but maybe a closed container. Also do not use them if regular or emergency access to the controls or off switch is necessary due to their location (see Photo). The Blade. After un-boxing and assembly took 5 mins and never even consulted instructions all you do is attach the legs (4 nuts) and install the axles and wheels (2 nuts). i used a flash light to inspect the blade. Replacement is not something i have considered or attempted so can not comment. The blade appears to be a steel cast or extrusion possibly also just a rough ground steel (probably mild steel) hobbed gear. the cutting edges are all single pass rough grind and mine even still had the heavy burr on it so it is obviously machine handled and no inspection prior to assemble. there is no relief cut for clearing chips or honed edge. It will go from CUT to GRIND to CRUSH in the span of 1-2 hours of operation. THIS is the the ONE major design flaw i see with the design (other than the design of the in feed more later) If any serious considerations for improvement of consistency of cut and longevity of the cutting edge had been considered a hardened steel blade or replaceable teeth would be my suggestion along with a relief for chip clearing and longevity of the cutting edge. Also improving the cutting edge will eliminate what i call "knockers" 3/4 to 1 inch pieces of wood that are cut down to about 6-8 inches get stuck and ride on the blade and just hammer against the side of the hopper until it finally catches and finishes cutting. In feed. If you have any thing that is not straight or with Y branching significant Pr-Procesing will be necessary. the machining has all the torque to grind these but will constantly jam up in the opening or hang on the narrow slot. If it would not void my warranty id have already simply cut the top open to get the twisted and bent items to pass cleanly into the cutting chamber. Processing hand fulls of twigs and leaves are also nearly impossible as you would need to hand feed single twigs and seriously i can just runs those suckers down with my mower. PPE (personal Protective equipment) Helmet and boxing gloves. This thing will fight you on the big and twisted. If something you are chipping is 1-1.5 inches WEAR GLOVES the kicking and spinning of the branches as they are beaten into pulpy submission by the total savagery that is 15amps of power will beat your hands to death like trying to dual marathon porn hub and Bruce lee movies at the same time. Watch out for the Pull when this thing gets a bite make sure your not grabbed or hook a glove on a small protrusion. At worst you would break a finger because only a 5 years old's hand might fit in the opening. unless your fingers are 8 inches long you don't have to worry about contacting the blade but just pay attention. Bent stuff will swing around i took more wood to the face in the last three days that a drunk college student on spring break from branches twisting around going trough the thing. wear safety glasses or a face shield if you have them or make sure you do a good processing before running twisted wood. Collection. The "canvas" collection bag included with the chipper is a wonderful addition to your reusable shopping bags, remember go green save the world. But i would never in my wildest dreams use the silly light weight piece of crap to hold 5 or 6 gallons of mulched wood and expect to get the bugs dust and wood splinter out for storage. Just looking at the thing i think it might survive 3 uses before some sharp and pointy got through and made just another grease rag with handles for my shop. I use an old Mop bucket is is a 6 gallon capacity and when the chute starts to clog up i go into a 5 gallon bucket. Also the piddly volume of the bag is just a joke. If you are considering this unit for purchase you've got volume to process. In 5 days i have mulched OVER 100 gallons of mulch. How do i know that? See photos, i have already given away a 40 gallon trash can to my neighbor for her garden the photo below is a 55 gallon drum i then filled, i have since moved on to filling individual 5 gallon buckets and am up to 5 of those filled to over capacity. add in whats fallen on the ground and your pushing 100-120 gallons of mulch.

    • First impressions
Style: Shredder
I have - no, HAD - a quite substantial brush pile that has accumulated in my back yard over the last couple years. Camp fires can only get the pile down so much though. And with the increased burning restrictions in our town, I needed a better solution. So I saw this on Amazon and went for it. This was a very easy assembly. You just have to bolt the wheels to the legs and the legs to the body and then you are all set. All the required tools are in the box. You do need a hefty extension cord, don't skimp out on that. A side note - the canvas bag feels pretty cheap. It will be used as a dust cover for the unit when I store it. As for operation, this was an impressive first showing. I ran the unit pretty much non-stop for a couple hours, it takes in every branch up to 1.5" without skipping a beat. Anything over 1.5" or so I am just cutting down to stack in the firewood pile, so this reduced my stick pile by at least 95%. And the resulting volume of a pile of sticks compared to the chips made from said sticks is wild. I wish I had taken before and after pictures. I will use the chips (they look more like 1" plugs of wood than shavings or chips) in my compost heap and may dry some out for fire starting. If you don't compost or have camp fires, honestly, this is still better because you can fit a TON of branches into a garbage bag and haul it to your local yard waste disposal center a lot more efficiently than as whole branches. The description "silent" is obviously not accurate, and I don't think any sane person would expect that. However, it is a lot quieter than I thought it would be. The noise is about that of an average shop vac. I have noise-cancelling earbuds that blocked most of the sound. Another interesting bit is the amount of dust that it kicks out - it's almost nothing. The action of the device is more like crushing on the brittle pieces and slicing these 1" plugs on greener stuff. I have not used it yet on fresh-trimmed branches, but the manual says you should cut them and let them wilt and dry out a couple days before stuffing them in. It makes sense - the action of the machine would definitely be gummed up by too-wet wood/leaves. I have seen reviews online say that the counter plate breaks or wears out with mild-limited use. The problem is that the counter plate seems to be perpetually out of stock (per the reviews on the Sun Joe / Snow Joe websiite). So I'm going to make sure to get the warranty registered ASAP and hope for the best. If this machine gives me 3-5 solid years of work without too much trouble, then it will have been WELL-worth it. If it causes me trouble, then I will amend my review. So far it's been 10/10. ... show more

    • I'm old and I've done a lot of shredding
Style: Shredder
I've been a Gardner and amature landscaper for 70 years. We moved from a 4 acre farmhouse/barn home to a half acre property in our 70's. My 9 hp patriot chipper was nearly worn out when we moved and when it died I bought the electric sun joe. I was not expecting much from it- the gas chipper was barely movable on wheels- the sun joe has wheels, but is light enough that I can lift and carry it. After two and a third years, I'm a total sun joe fan. I put virtually no plant waste on the street. I chip regularly once a week or more in the summer and fall and at least monthly through the winter. Each time is 20 to 30 minutes. The sunjoe has not only survived, it chips 90% of what the gas chipper did and its quieter, safer, gentler, and cheaper to run than the gas chipper. One caution, and one problem that could be corrected in the design. Caution- safer than gas, but this is a powerful motor. Loading branches, especially with thick leather gloves, I nearly pinched fingers when I first used. Problem- the lower shute often clogs, especially with greener branches or vines. I need to stop the chipper and dig put the bottom shute with a branch, sometimes after just five minutes. This problem could surely be improved by a minor design change. What I do with a stick could be duplicated by a device incorporated in the shute. ... show more

    • Some design flaws. Needs 2nd edition
Style: Shredder
Review Image by Ian Ollmann Ian Ollmann
Review Image by Ian Ollmann Ian Ollmann
This works. My wife was skeptical, but it has chewed through everything as long as it was less than 1.25" thick. Per other reviews it works best if you just let the machine pull the materials through. Big sticks can pull through little sticks. I expect to be able to get through 8 trees with this that fell down in this winter's storms. When I am done, I have a 2" carpet of chopped leaves with some shredded wood chunks mixed in. I'm sure the worms and such will make short work of this soon enough. The reduction in volume is tremendous. Critical review =========== While the machine is mechanically sound and suited to purpose, there are some design flaws that should be remedied in version 2 of the device for safety, usability and maintainability: 1) The device is unwieldy and difficult to maneuver when moving the shredder to the work site. It is too short for decent luggability and needs a longer handle. The men in my house are all over 6' tall. I'm 6'6" and it is really awkward to walk while bending over like that. It tangles in your feet. a longer handle would allow me to stand straight and have it away from my body while walking. Measure a golf caddy some time. Compare it to this. Too short. 2) the distance between the bottom of output funnel and the ground is too small. (The inclusion of the bag is frankly ridiculous. I'm sure marketing insisted on this. It just makes the problem far worse.) The legs should be 4" taller and the base a bit wider. Since shredded piles are conical, this should allow for much more material to collect under the device between sweeping it away. Cost scrub the bag. Add longer legs. 3) if the shredded debris pile climbs up and reaches the bottom of the output funnel, the funnel is absolutely guaranteed to clog. The output funnel is slightly tapered at the bottom which encourages clogging. It should either be straight sided or even slightly flared. Frankly, were it not for safety, I would argue this machine would work 10 times better if the bottom four inches of the output funnel were simply removed. 4) suburban users would probably really like this better if there was an option for an attachment that would mount the shredder on the top/side of a green yard waste can, so that the output went straight into the bin. This would solve the height, clogging and luggability concerns. Yard cleanup of shredded debris would be a snap. 5) when it clogs, the leaves and such start to recirculate through the machine. They go out the crusher, but due to back pressure from clog, then follow the wheel around and end up on top again. As part of this travel it brings the leaves past a hole in the working enclosure which allows leaves and other flammable material to become stuffed up into the right side of the plastic housing against the wiring and motor. This looks to me like a fire hazard and should be remedied immediately. There should not be a path for debris to leave the shredder and find their way into the motor area. See attached picture. 6) the "lozenge" between the crushing wheel and its axle very easily can fall out onto the forest floor while field servicing the machine to replace the strike plate, especially if the machine stops with the lozenge pointing down and the crushing wheel slides off the axle. This happened when I tried to tip it forward to get the leaves and other whatnot out of the housing. Perhaps this part of the axle might be welded on or fabricated in place. See picture. ... show more

    • Good product, GREAT Customer Service
Style: Shredder
The CJ603E is a simple, easy-to-operate chipper that produces decent wood chips quickly. There are a few consumer-created videos out there; I recommend watching them, they do a better job giving an honest analysis of the device than a write-up can. I'll get into some finer points below for anyone who finds them useful, but the TLDR is: The machine works great, just make sure you set it up correctly, don't skimp on the wire gauge of your extension cord (super important - if you read one thing below, make it that) and keep the rotor cleared out. If you have any issues with the device, give Sun Joe a call. They pick up their phone, a real human talks with you, and they bend over backwards to get you up and running. EXCEPTIONAL customer service. Some particular points I'll mention now that I've used the chipper for a couple hours: It grinds branches up to 1.5 inches diameter easily, which is pretty thick for an electric chipper. The specs say it'll take branches wider than that, but I don't push it. The input chute acts as a gauge for maximum branch width. With a little common sense, you'll never have a problem with branch size. Steer clear of branches you have to pry and force to fit, odd bits of hardware, lengths of rebar, unpopular in-laws, etc. and you'll be fine. Keep the output chute clear. Wood chips will stack under it, then up into it and finally into the mechanism if you don't sweep them away. From time to time, it helps to shove a stick up into the output chute and rattle it around. You'll get a slot-machine jackpot of wood chips that were stuck to the rotor. Looking down into the input chute, you'll have a clear view of when the rotor is getting clogged and needs that help. It grinds wood just fine but doesn't do much with foliage. If you're looking to make fine leaf mulch, there are other machines for that. If you want wood chips, this is likely the lowest cost, highest quality option and offers maximum convenience of use. IMPORTANT POINT: If you don't know about extension cord wire gauges, take a few minutes to read online about them. You'll save yourself a burned-out motor and extend the life of your other electrical tools while you're at it. For this chipper, make sure you're using a cord with at least a 12-gauge wire for cords up to 50 feet. For anything longer than that, you'll want to buy a 10-gauge extension cord. Yes, it costs almost as much as the chipper, but all of your electric tools will last a few years longer, so it pays you back. We're running this chipper on a 100 foot 10-guage cord that is as thick as a man's finger and weighs a ton, and it has done a SUPER job. Again, Sun Joe's customer service is unbelievable, especially considering the price level of this product. They picked up the phone on the second ring and shared useful information. We ended up needing a new unit, which they offered right away. They shipped it the instant the old unit was dropped off at UPS and we were chipping wood 18 hours later. As I write this, we're up and running with our new chipper while UPS has yet to deliver the old one to Sun Joe. And Sun Joe paid for all the shipping, all the way around. I actually worry about their ability to stay in business with customer service that good. Amazing job, guys. In short, this device is a great deal that may not last long. I'd get one while you can, set it up properly and use it for a long, long time. ... show more

This is a review of the Sun Joe CJ603E 15-amp Chipper/Shredder, purchased on Amazon.com. Delivery was quick, as usual, and the package arrived in good shape. I chose this brand and model based on product descriptions and customer reviews not only on Amazon but on other sites as well. I wanted something that would shred limbs of at least 1.5 inch in diameter and at a price point of $200 or less. Satisfied customer reviews were extremely important in the decision. This product matched all my requirements. Assembling the shredder was simple, but a couple of issues did cause some concern. A quick read of the manual and an inspection of the boxed contents verified that all the parts were there, but the rubber leg tips did not match the ones in the manual, nor did they match each other (see photo)! What’s up with that, Sun Joe? Obviously this didn’t affect the machine’s performance, but it did speak to the issue of quality control and left me with a feeling of foreboding right off the bat. The other issue concerns the wheels, which, hard as I tried, would not rotate properly. The instructions for assembly are straight-forward and I followed them to the letter, but the left wheel turned easily and the right wheel not at all. In fact, pushing the unit forward with the stuck right wheel eventually caused the left-wheel’s lock nut (yes, I said “lock” nut) to come loose from the axle! In addition, the decorative snap-on wheel cover on the left fell off several times. Inspiring confidence? No. Fortunately for me, I store this unit in my outdoor shed and operate it just outside of the shed, so rotating wheels aren’t that important, but it would be nice. Now for the most important part, how does it work? In a word, great! I had a stack of limbs and branches from several crepe myrtles ready to go (I know it’s not popular to commit “crepe murder” anymore, but I do it anyway). The largest of the branches did not exceed the specified 1.73-inch maximum but were easily 1.5 inches in diameter and anywhere from 4 to 7 feet in length. I started off, skeptically, by inserting the very smallest twigs to get a feel for the machine and to gradually build up my confidence to try larger branches. I feared the motor would burn out on the largest one, but it handled it with ease. The more I fed it the more comfortable I felt with using it. After a good hour and a half of use, I knew this would be a machine I would enjoy using for some time to come. Safety-wise, I have no concerns. The way it’s designed, you can’t accidently get your hands in to reach the chopping mechanism. The enclosed paddle is good for stuffing extraneous material further into the hopper but was rarely needed. The machine feels very solid and of good weight, so it is very sturdy and not apt to tip over. You couldn’t possibly feed branches larger than specified because the hopper holes won’t allow it. The overload protection feature cuts the power to the motor should the chipper become clogged. Overall, you can feel safe using this product, although I would advise you to wear goggles to protect your eyes from any flying debris (none of which I experienced). The machine is noticeably quiet considering its purpose. I’d say it’s about as loud as a typical home vacuum cleaner, but I’m sure that being outside makes a difference. Having said that, I didn’t feel that I needed any special ear protection gear while using it, although it is recommended that you do so. It comes with a collection bag, which seems to get a fair amount of negative feedback in Amazon reviews, but I thought it was quite useful. It’s better, for me at least, to empty the chips into a bag than to let them fall on the ground. I just park my wheelbarrow next to the unit and fill it as I go, then off to the compost pile. Speaking of chips, they are about an inch long on average (see photo) and sometimes the very thinnest of twigs escape into the collection bag unscathed, but I have no doubt that the material is of sufficient size to compost well. Overall, having spent only one session with this machine, I am happy with this purchase. I do feel that Sun Joe failed its quality control inspection on this delivery (the mismatched leg tips) and I’m at a loss to explain the engineering failure to get both wheels rolling at the same time, but these issues do not affect the operation of the machine at all. The unit feels strong and sturdy, the motor processes the largest branches with ease, and the quiet operation is an added plus. If you’re looking for a chipper for small at-home projects like mine, I would recommend this machine. The only thing keeping me from giving it perfect marks are the issues I mentioned. ... show more

    • Quiet, lightweight, easy to operate.. and works right.. the first time.
Style: Shredder
After spending $600 to have a brush pile hauled away, last year, one of my new years resolutions, was to get a wood chipper, and never have to spend that money again. Last year, we decided to clean up our backyard, for the first time in a decade or so. Due to the fact that we live on the edge of woods, we had an extremely large number of small saplings growing in the yard. After cutting them all down, and adding them to our ever re-growing brush pile, I decided to start looking at some wood chippers. Now due to the crazy prices on gas, right now, I knew up front, that I wanted an electric powered one. The bonus of not going deaf while using it, would be a major plus, too. Sure, I wouldn't be able to fit 1ft wide chunks of wood, but most of the wood we're disposing of, were 1-2" or less in diameter. I saw this one, out here, and regardless of all of the glowing reviews, just couldn't bring myself to buy it online. So, I decided to check the various stores around us, and wound up settling on another brand. I brought it home, and started to assemble it, only to find out I had missing pieces. So... back to the store it went. The store replaced it, and I brought it home, and assembled it... only to find a bolt missing... ok.. fine.. this time I just called the store, and they said they'd give me a bolt. So I took another trip (did I fail to mention the physical store is roughly 30 mins away?) retrieved the bolt, and came home and finished the assembly. Great!! The product is assembled.. and I take it outside to start working on the brush pile. The first thing I notice, is that some of the branches won't fit. The manufacturer claims 1.5", but the slot to insert the branches is only 1.2"... ooookay then. So, I feed a few branches through.. and the unit gets jammed due to some evergreen fronds. They're not big, they just apparently got stuck in the feeder, after the chipper mechanism. So, I have to take the unit apart, to clean those out. Fine. I continue to chip a few branches, and the unit stops, indicating it's overheated.... for maybe 10 branches, in the pile of several hundred. I wait for the unit to cool down, feed another 4 branches through, and it overheats again. This time... no matter what I do, the unit will not turn back on, even though it indicates it should be. Frustrated, returned the unit.. came home, and ordered this one. .. and what a purchase it is :) It chops up branches with no issues, and while it doesn't exactly produce full on 'mulch' like some people want, it DOES make spreading out the branches, into gardens and compost piles, VERY easy. I went through the entire brunch pile, today, and then went out of my way to give my trees and bushes a trim... just so I could chop up the branches... It's fantastic. How much was the entire brush pile? Approximately 22 of the little canvas totes the unit came with, full. Not bad at all. Finished it up, wiped it down with a damp cloth.. and it's ready for the next time :) Now, there are a few complaints, too, but nothing that glaring. 1.) if you are feeding small length twigs into the unit... say, 6-10 inches long.. the unit will occasionally flip them back out. Not a big deal, just gotta remember to wear gloves, and eye protection.. and keep your hand over the opening while feeding small items in, so they don't bounce back out. 2.) The wheels on the unit are definitely the cheap style plastic things. They are serviceable, but maneuvering the chipper over the yard, via the wheels, is somewhat counter productive. I just found it easier to carry it, as it's not very heavy. So... if you're that person, like me, who is sitting on the fence, trying to decide if you really want to purchase this thing online. Do so. It'll potentially save you some frustration, and make your yard nicer in the process :) ... show more

    • Works great but not exactly a chipper/shredder
Style: Shredder
The chipper works great. It has gone through anything smaller than I'd keep for firewood. I really like that it is much more controlled than most chippers I've used. Instead of a fast spinning blade, it has a large thick cutting blade that methodically chops branches into chunks. I also really like that in the one case where the machine got stuck it simply popped the breaker (on the control panel). I was able to turn it off, reset the breaker, and reverse the motor (another switch on the panel) to clear the jam. Worlds better than the next lower model that cracked the plastic case from all the rattling and bouncing from spinning the blade so fast into a stick. The primary negative I can offer is if you are looking to produce something like bark/mulch you will likely be disappointed. The machine cuts branches into 1" chunks rather than chips (I'll try to remember to add a picture). It's fine for my purposes but it doesn't look as nice as bark/mulch. The only other con is that it is kind of heavy. I assume that's because of the gearing that is going on between the motor and the cutting wheel. Overall I'm very happy with it and would recommend it as long as the chunks it produces aren't a problem for you. ... show more

    • Surprisingly powerful and convenient
Style: Shredder
This thing very efficiently reduced a big pile of cut, woody brush and saplings into a much more manageable pile of chips and shredded bits. Assembly was pretty straightforward, but the included diagrams might be a bit confusing at first, as it's not clear what orientation things are supposed to be when connecting them. There's only a handful of parts though, so even if you get it wrong at first, fixing it only takes a few extra moments. My particular unit didn't sit very level on the included legs. This is likely adjustable with a little tweaking, but since I was mostly going to be using it on my lawn, it didn't concern me too much. This is pretty powerful, although sometimes it sounds like it's really struggling. It is possible to overload it, and I had it stall once after feeding it a particularly thicc branch that was admittedly probably pretty borderline too big. It even produced a small puff of magic smoke before I managed to hit the e-stop. This really concerned me at first, as I was afraid that I burned up my new favorite tool already on my first day of using it. I let it cool for a couple minutes, plugged it back in, and it was back running good as new. I didn't bother with the included fiber bag, as a 5 gallon Home Depot bucket seemed like a much better method to collect the wood bits. I think I'm right with this. Nevertheless, it's nice to have some included bagging system. If I had one criticism for this unit, it would be safety design... Now, I'm not going to claim that this chipper is unsafe to operate. It's not. I think you'd have to really go out of your way to hurt yourself using this thing. HOWEVER, people being people, I feel like SunJoe could make a design change that would make much more sense, safety-wise. The emergency stop button is at the top of the panel, and it's kind of a small, thumb button. They could very easily have skipped the cup holders (yes, this has cup holders), and put a much larger and accessible e-stop switch in it's place. You're not likely to injure yourself operating this, but I can definitely see a situation where some long piece of clothing or hoodie tie get's grabbed into the mechanism or stuck on a branch that is feeding into the unit. I feel like this would be a sensible change that would cost SunJoe very little to implement. I guess the Chinese designers think that Americans need cupholders in everything? I dunno, lol. ... show more

    • A workhorse
Style: Shredder
We have a good-sized town lot with fruit and shade trees. This machine is more of a cruncher than a cutter. Twigs less than 1/4" only get crimped, not cut. But just that crimping allows for decay to begin. Larger branches come out as crushed chunks about 1-1/4" long. The output is not as pretty as sliced chips, but our previous machine required constant feeding. This chipper feeds itself. You can grab another handful as the previous bunch is being devoured. Leafy branches tend to clog in the output chute. Overgrown kale went through just fine, cabbage, not so much. I am happy to have this machine. ... show more

    • A handy chipper for the gardening chores
Style: Shredder
I invested in the Sun Joe CJ603E chipper/shredder because I had pile of branch cuttings and no where to dispose of them properly. The waste disposal authority wouldn't pick them up unless I paid the fee to have them removed. If I put the cuttings in my trash container they refused to empty the trash can, and issue me a warning I could face a fine! I was able to get this unit shipped to Guam without problems and arrived in 11 weeks. Assembly was easy requiring bolting on the legs to body and the wheels to axle rod with tools included with the chipper. Once assembled the chipper performed, well under certain conditions. The Chipper can chip small twigs to 1-3/4 inches in diameter. The mechanism of the chipper has a rotary blade spinning clockwise at 60 RPM, and a "Counterplate" made of aluminum is held at a distance from the rotary blade that provides the chopping action; the chipping efficiency is dependent how close the Counterplate is to the rotating blade. The controls are neatly organized on a central panel aft of the hopper opening, with the GFI-protection indicator in the middle. The power cord for the unit is 13-3/4" long, and has a convenient clip to keep the extension cord from being unplugged while in operation. All the branch cuttings were of soft wood and fibrous plants ranging from twigs to 1-3/4 diameter branches. The Sun Joe CJ603E has the words "Green" and "Shredder" in its in title which I find are misnomers to what it can actually do. The design of the hopper in relation to the spinning blade can quickly teach you a lesson how important it is to wear gloves & protective glasses. The shape of the open is the first indication, the large round opening means the branch needs to be straight and clear of small branches, the narrow long opening warns you that bulk feed items need to be smaller or compact. Exceeding the parameter of the hopper opening will do a number of problems which I will describe later. Sun Jose chipper is "Green" in color but it does not perform well chipping green branches, especially fibrous plants like Ti leaf or Taro stalks they come out in large 1-inch chunks, or half-chomped long pieces looking like toy snake. The best results is when the cuttings are completely dry does the Sun Joe CJ603E mulch & shred with efficiency. When I powered up the Sun Joe CJ603E it sounded like a very loud vacuum cleaner, so I always made sure to do my chipping not so early in the morning that way my neighbors would not find the noise irritating. As I mentioned before care & caution need to be exercised when feeding large branches into the hopper. I thought the other reviewers were being over dramatic for comedy effect. Once the rotating blades takes to that branch it will quickly churn that length of branch, and if the branch is not straight it will twist and swing! Chipping large green branches on the other hand will quickly clog the chipper, the only way to clear it quickly is to feed a completely dry branch. Bulk feeding twigs, roots, and medium branches need to be dry or it will end up tumbling inside the hopper. As for shredding grass clippings or dry leaves? Not possible as they pass through intact. The cloth bag that comes with the chipper was a disappointment. It does not hold its shape, and I had to constantly make sure it was under the exit chute because all of the chipping did not make it into the bag. The feeder paddle that was also included was not much handy, every time a small branch that ended up tumbling in the hopper it was too short to do much help. I had to use another branch to get the tumbling branch to catch in the rotating blade. The maintenance of the chipper is simple. If the chipper's performance is falling short adjusting the Counterplate's distance from the rotating blade is easily done turning the adjusting knob. I would turn the knob until I spotted small slivers of aluminum metal fall from the chute. I wished they would have included a hook to hang the feeder paddle on the chipper. Access to the counterplate & the rotating blade is easy by removing the 4 bolts on the cover, and removing the cover. Overall I am happy with this chipper it does fast work on cuttings and provides me with lots of free mulch to keep the weeds down. ... show more

    • Very effective
Style: Shredder
The first machine that arrived was faulty and could not be assembled, but, as is typical, Amazon promptly sent a replacement and did not wait until they received the item I was returning. The replacement model assembled very easily and it is very effective at churning up bushes and tree branches. Being able to reuse the woodchips in our own garden rather than having to bag up the branches and have the council take them away is a win twice over. A couple of times the motor has cut out when the machine could not cope - even though the branch managed to fit through the slot. But this seems to be an effective security/safety device. Pressing the reset button and putting the drive into reverse briefly has resolved the issue. I thoroughly recommend this machine. ... show more

    • MORE THAN A LITTLE IMPRESSED
Style: Shredder
I was skeptical at first, but this little machine proved itself to be a mighty little workhorse, considering the price and the limited capability. I had accumulated quite a lot of brush and tree limbs, as the result of having a rather heavily treed property and having done a lot of recent pruning on some bushes. I did not want to buy a big, heavy-duty, expensive, gasoline-powered chipper, because once I got the rather huge pile of limbs done, I probably wouldn't need it again, except for maybe an hour or two in the Spring or Fall. This little guy knocked it all out and didn't stop until the job was done. I literally ran it for several hours at a time, stopping only to empty the five-gallon bucket that I used to collect the mulch product. It actually seemed to enjoy it! The only problem I had was when I tried to mulch some smaller debris along with some of the branches, because I didn't want to take the extra step of separating the two. But, as long as I fed it limbs or branches within it's 1.73 inch diameter limitation (I may have even had a couple that were 1.74 or 1.75 inches at the widest end - hehe), it ate them up eagerly while dispensing some pretty decent mulch product at the same time. So, after three long days of chipping and shredding, this hasn't showed any signs of slowing down or wearing out. It's still working as good as it did when I started. I'll give it a much deserved break for a while and after six months or so, if I'm not equally impressed, I update this review accordingly. But for now, this is highly recommended. ... show more
