G'day Tony,
Welcome to the forum!!
I guess the first question is: What sort of bark?
It will come as no surprise to those folks who frequent this site that I have a Greenfield Piecemaker at home I abuse on a very regular basis! It gets stuffed with palm fronds from Golden Canes and Alexanders ( minus the the area that wraps around the trunk from the Alexanders) on an almost fortnightly basis. I have a LOT of big palms here. I can't stop the thing!!
It has a single heavy cutting disc with two blades. It's a very simple design. I doubt I could do what I do with a flail design shredder.
Hope this helps,
Cheers
