摘要:
A chain saw guide bar (38) for a tree harvester is arranged to yield when an excessive force is applied such as when the guide bar (38) becomes jammed in a cut. Yielding of the guide bar (38) protects the bar holder (48) from damage. The guide bar (38) is heat treated or otherwise structurally modified to provide the desired yield strength.
