An improved log charging system for a sawmill having a sharp chain infeed conveyor includes a log turning station for scanning and rotating a horizontally supported log about its longitudinal axis to a desired orientation that will produce maximum lumber yield, and a charging system for clamping the log in the desired position, lowering the horizontal log, while clamped in the desired orientation, forwardly and downwardly relative to the sharp chain, and pressing the log downwardly toward embedded engagement with the teeth of the sharp chain by a continued travel hand-off device. To increase the speed of the log charging operation, the log is preliminarily scanned prior to transport to the log turning station, thereby to permit adjustment of the log support device for size before it receives a given log.
