A device that does not require hearing protection and does not pose neighborhood problem, it is fast, but tends to clog if you put too many branches with leaves, fortunately there has reversing allowing unclutter the machine.Il made coarse chips but that make the BRF (RCW fragmented), mulch or compost to feed smoothly. We just adjust the spacing of the rotor and make finer if we find that this is too coarse. This shredder is designed for 4cm in diameter branches but it is better to stick, like most mills of 3cm, especially if the wood is hard. This machine works without problems for two years, however, the recessed plastic wheels are of poor quality and may not last.
