Abstract: A log debarking chain flail apparatus 10 is illustrated in FIGS. 1 and 2 removing bark from a log 12. The apparatus includes two opposing flail assemblies 18 and 20 having a plurality of chain flails 22 that extend radially outward as the assembly is rotated. Each of the chain flails include a plurality of chain links extending from an inner end 22a to an outer end 22b in which each of the links has a longitudinal segment 46. A tooth 50 is formed on one or more of the longitudinal segments 46 for scraping and/or cutting the bark from the exterior 14 of the log 12.
