Got a Jinma Chipper this morning and fired it up for a few minutes. Boy that thing really is a beast! It just chewed up all the branches we had cleaned off of a 17' Christmas tree and a couple 2" braches too. Took them faster than I could pick them up. I didn't feed it anything even remotely approaching it's capacity. It chewed up all I fed it with no strain at all!
It has a 175 pound flywheel, and weighs 880 pounds! Belt driven from a 540 rpm pto.
There is a powered feed-roller right before the spinning blade face, about six inches wide and four or five inches in diameter with coarsley serrated blades welded along it's length. That feed drum is mounted on a vertically pivoting yoke that can pivot up and is spring-loaded downward so it will climb up over a branch that is poked at it. Once it grabs the branch, you can walk away and it will feed the whole thing at just the right feed rate.
They are a bit back tippy, so when it is off of the tractor, you want to be sure no one lets it tip back and fall on them. I think I will bolt some 4x4" pressure-treated skids to the base and run them back an extra foot lnger than the metal base to minimize this problem.
I will never be feeding this thing anything close to its capacity, because we have a wood stove and burn anything bigger than 2".
I am not particularly big on reminding people about obvious safety warnings, eye protection and the like, but it better go without saying that you don't get anywhere near this thing with loose clothing! It would make "bone-in ground round" out of you pretty fast!
