ABSTRACT:
A lift bar spaced forwardly of the front end of an elongated tubular frame member supported above ground by a pair of wheels, is positioned in abutment with a log at ground level by forward tilting of the frame member to a pick-up position. In the pick-up position, a pivoted hook on the frame member drops into engagement with the log to hold it on the lift bar above ground during wheeled transport. The log is unloaded by retracting the hook and rolling it off the lift bar over retainer jaws fixed to the lift bar on opposite sides of a pivot plane in which the hook is displaceable and through which the frame axis extends perpendicular to the lift bar.
