This replaced a cheap electric chipper and is SO much better built. They obviously didn't cheap out on the components. They provide tools (OK, crappy tools) for both assembly And service/maintenance. It is not silent but it Is Much Quieter than the cheap chippers (similar to a table saw). Even the collection bag is higher quality. The main "wear" component is easily replaceable, and inexpensive (and there are even after-market versions!). And, no joke, it has hub caps and cup holders (though the cup holders are probably there As a joke).
One of the best purchases I’ve made in years- way better than expected.
I put this chipper through the works and it handled everything’ thrown at it. I have been trimming and/or cutting down trees and limbs and had a mountain in my backyard. I was trying to determine how to handle the cleanup. Too big for garbage, too expensive and time-consuming to bring to a waste disposal facility. Most of the waste was from an incredibly messy weeping bottlebrush tree with limbs less than 1”. Some was from a few bougainvillea bushes with nasty thorns. Within a few hours, all waste was condensed to a rather small pile of chips. I’m glad I bought this model as opposed to the cheaper models. This unit ripped 1.5” limbs with branches, small leaves, thorns and seed pods attached…no problem.
The SunJoe staff suggested the CJ603E as a good chipper to reduce my corn stalks and other soft and or damp materials. It performed well when I trimmed a pile of hedge branches and leaves. It took a while to chew up all the short items I had cut with my pole trimmer due to the small opening but it did get the job done and with no clogs.
After looking at what was on the market, I decided to go with the CJ603E. I have to say I'm impressed. Here in the Northeast we have plenty of rock maple, oak, and pine that's constantly shedding branches. Add the branches that need to be pruned, and it adds up quickly.
Assembly was easy, with only the two legs and the axle to be installed. It is pretty stable and easy to move. It was up and running in 10 minutes. I removed the cover plate and looked over the cutting mechanism. The "star wheel" cutter looks to be forged, and it is keyed to the gear box output shaft with a slide fit, so replacement or sharpening looks to be pretty easy. The aluminum counter plate has a steel hinge pin and looks good and beefy. I buttoned it back up and started clearing the brush pile.
Understanding that the extension cord wire gauge was critical, I purchased a 12 AWG, 50 ft. cord and fired it up. The stuff I was cutting included all of the woods mentioned above and more. Most of it was dry, but some fresh cut maple branches were in the mix. It cut almost everything I fed into it. I gave it the acid test and fed a 1.5" fresh cut maple branch in. It ate most of it but finally stalled out, and I had to back the remainder out and toss it aside. It handled smaller fresh cut branches easily. Dry branches up to the opening size bogged it gown, but it ate them all. If the counter plate is set right it even cut very small twigs and dry wild grape vine. The output did clog sometimes when the odd leafy branch was fed through it, but it was easy to pull it down and into the bucket.
It is not a leaf shredder, but for chopping up brush it does the job. It does tend to cut branches into 3/4" to 1 " long split chunks that will be used to mulch the flower beds. It's not a shredded mulch, but it looks ok, and it'll keep the beds looking clean.
Having seen some videos where the machine bogged down on even small branches, my guess was that they used undersized extension cords. A properly sized extension cord is a must if you want to get the best performance.
Last but not least, this isn't a commercial chipper, but it can cut up brush at a decent clip with no issues. Well worth the cost, and a decently powerful, trouble free machine.
I own this Shredder for 3 years and only repair I did to it was to sharpen the cutter wheel. It does what it advertised. I strongly recommend this product to anyone for this price. I don't hasitate to buy another one if I needed to.
The CJ603E is a very effective machine and easy to use. Its light weight makes it easy to move. I have owned many woodchopper but find this product superior to all of the others.
I’ve been using the chipper to clean up branches in the yard. I’ve used it continuously for one to two hours each time. Being a guy, I wanted to see if I could load it up with too much. You can. But, if used within its limits, it will go and go and go! I am very happy with it so far and can recommend this chipper for yard work.
