The rotary ring of a log barker has a flaring mouth carrying limb-cutting bits in radial planes. Hooked ends of swinging arms rotate around a log as it is moved lengthwise to scrape off the bark. Bark and limb pieces fall into a hog having stationary shearing bars cooperating with rotary shearing bars carried above a plate rotating about a vertical axis. Hogged material dropping through apertures in the plate is swept out of the casing by vanes carried by the rotor.
