The larger chipper shredders are designed for trees and tree trimmers to use.
Smaller machines are designed for smaller branches up to 3 inches and has a hopper for green waste.
It is good to have a chute so the chipped material can be directed to a collection truck or area.

These are not maintenance free. You will need to do regular maintenance and the blades need to be changed when they get dull.
Our community garden considered getting one of these but we have a lot of theft in the gardens. Someone with a tow hitch would have to keep it at their house and bring it in when it was needed. Tillers, tools, chain saws, wheelbarrels, ladders, and even backpacks have been stolen from the garden along with the bananas, chayote, and other produce.
Happy gardening in Hawaii. Gardens are where people grow.
