Abstract
A trimming device and method maintains a first trimming member of a tree harvester head at a preselected transverse position relative to a tree trunk during relative longitudinal movement of the tree trunk. A first control device having a tree trunk engaging portion movably connected to the first trimming member selectively establishes the relative transverse position of the first trimming member and the tree trunk. An actuator urges the tree trunk engaging portion into engagement with the tree trunk and the first trimming member at the preselected transverse position.
