- Item Weight
- 38.6 lb
- Reduction Ratio
- 21:1
- Cutting Capacity
- 1.7 inches
Twenty-one to one is the number that matters on the CJ603E. That reduction ratio is why a season of prunings collapses into a bag or two of chips instead of a pile you have to haul away, and it's the spec we weigh hardest whenever a corded chipper shredder shows up. The 15-amp motor is rated to 1.7 inches, starts with a button, and needs no gas, oil, or pull cord — worth more than it sounds when you're cleaning up in twenty-minute stretches after work.
In practice, an inch is the working size. Straight, dry branches at that diameter disappear steadily; lean toward the rated 1.7 and the machine starts thinking about it, so feed rate matters more than the number on the hopper. The chips come out coarse enough to spread on paths, the push paddle earns its keep on the last few inches of a limb, and the bag catches most of what comes through.
Leaves are where it stumbles: a handful of them will clog the housing and turn a short job into a disassembly project. The 38.6-pound body rolls to the pile but is a two-handed lift into a truck, and the listed 94 dB is loud enough that hearing protection stops being optional. The part that seems to fail first isn't the motor but the plate the paddle works against; two years of warranty, matched by only one other pick here, is what keeps that from being a dealbreaker.
So this is the chipper we hand to a homeowner with a mixed pile of prunings and somewhere dry to store it. It isn't the fastest or the lightest, but the ratio does the real work, the coverage is there when something goes wrong, and the quirks are the kind you learn in an afternoon. We kept it on the bigger limbs and let the lighter machines take the twigs.
What We Like
- 21:1 ratio shrinks a pile fast
- Push-button start, no fuel or fumes
- Two-year warranty on a corded chipper
- Takes branches up to 1.7 inches
Worth Noting
- Leaves clog the housing and need clearing
- Heavy at 38.6 pounds and loud at 94 dB
We recommend the CJ603E for most yards: its 21:1 reduction turns a season of prunings into a few bags, and the two-year warranty covers the part that tends to wear.
