A butt flare reducing apparatus for logs is provided. The apparatus includes a machine frame, a stator ring assembly fixedly coupled to the machine frame, and a flare reducing tool adjustment assembly movably coupled to the stator ring assembly. The apparatus further includes an actuator coupled on one end to the machine frame and on the other end to the flare reducing tool adjustment assembly to move the flare reducing tool adjustment assembly between the opposing end positions, and a rotor assembly rotatably coupled to the stator ring assembly. The rotor assembly includes a rotor frame and at least one flare reducing tool movably coupled to the rotor frame to translate linearly toward and away from a longitudinal axis of rotation in direct correlation to movement of the actuator and flare reducing tool adjustment assembly to adjust a log processing diameter. Related methods are also provided.
