摘要： A guide bar mounting arrangement for a tree harvester. The tail end of the guide bar (38) is provided with a center slot (40) and pin receiving slot (42) at each side thereof. A sliding block (48) has a center boss (56) and pins (50,60) permanently or removably mounted therein at the sides of the boss and the combination is slidably mounted in a fixture or base member (46) fixedly secured to the harvester adjacent a drive sprocket (S). The guide bar (38) is fitted to the sliding block (48) center slot receiving a center boss (56) of the sliding block and the pin receiving slots (42) engaging the pins (50,60) of the sliding block. A saw chain is entrained around the guide bar (38) and drive sprocket and the sliding block moved relative to the sprocket to tension the saw chain. The sliding block (48) is forced against the base member (46) to clamp the bar in position.

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.
