The tools used to reduce yard waste range in capability from light-duty electric shredders that can convert a bushel of dried leaves into a quarter bushel of fluffy mulch in 10 minutes, to trailer-mounted, diesel-powered chippers capable of converting a half-ton of 8-inch-diameter tree limbs into chips in about the same time frame--so think about what you want to accomplish before taking the plunge.
In practice, most folks would be best served with a chipper-shredder combination unit--you can load the hopper to shred leaves and twigs, and send branches down the chipper chute to create coarser material at the same time.
Mobile chippers pose potential dangers to operators, who can become caught in the feed mechanism and pulled into the rotating chipper knives or struck by the hood of the machine while it is being opened or closed with the knives still rotating.
