A log-feed apparatus used in a log-feed assembly, where the assembly functions to advance a log along a transport axis in a log-debarking system. An elongated arm in the apparatus is mounted at an inner end for swinging of its outer end toward and away from the transport axis. A spiked feed roll, journaled on the outer arm end for powered rotation about the arm's long axis, is carried on the outer end of a shaft which is journaled on the arm by a pair of axially spaced bearings. A gear reducer mounted on the arm, intermediate the arm ends, is driven by an arm-mounted motor through a flexible belt drive. The output of the gear reducer is drivingly connected to the inner end of the shaft by a torsionally flexible rotary coupling. The shaft and bearings journaling the feed roll on the arm act to isolate all components of the drive train which extend between the shaft and motor from substantially all but torsional load transmitted by the feed roll during operation of the log-feed assembly.
