ABSTRACT:
A mechanical pull-through delimber for delimbing a felled tree comprises a delimber section having first and second trunk supports for receiving and supporting a portion of a tree trunk, and a delimber assembly mounted between the first and second trunk supports. The delimber assembly comprises delimber arms mounted to pivot inward to a tree trunk delimbing position and to pivot outward to a tree trunk loading position, and a delimber arm actuator. The delimber arm actuator connects the delimber arms with the second trunk support, so that the weight of a tree trunk supported by the second trunk support will cause the delimber arms to pivot inward to a tree trunk delimbing position.
