I have a 20hp power Echo/BearCat chipper shredder 5" capacity ( SC5720) ( and it can do it) looks like a small sized commercial unit. Tall exhaust chute that is directional controllable so you can blow into a box truck or trailer. What it doesn't have and most small units do not, is a crush feed system. it is just gravity feed although once the knives get a hold of the material it pretty much self feeds. ( sometimes ya got to hang on to a 4" or 5" dia. pole to slow it down) It has been a very good unit for me. Simple one bolt removal to open the grinding chambers for clearing should you jam it up ( that's what sold me after the previous unit) or blade replacement.
