ABSTRACT:
A log yarder including a support vehicle; a horizontally rotatable framework mounted on the vehicle; one or more booms mounted on the framework; an elongated heeling rack mounted on the most terminal boom; a slack kicker for skidding logs to the yarder; and a grapple for loading or placement of the logs so skidded. The combination of slack kicker and grapple enables a single operator to skid a fallen log to the grapple for loading the log for hauling or for deck placement. The slack kicker includes a cable which is threaded through one end of the heeling rack which may be used to skid the logs into a substantially aligned position with the grapple for convenient and efficient loading.
