ABSTRACT:
A tree harvesting guide bar adapted for treating stumps with a treatment material as the tree is being harvested is provided, and more particularly a valve arrangement for enabling connection of the guide bar inlet to treatment material sources on a variety of different harvesting machines is disclosed, such that the inlet not connected to the treatment material source does not need to be independently and manually plugged to prevent undesirable outflow.
