Abstract
A tree processing machine having a boom, a tree processor head carrying tree processing elements, and a rotator rotatably connecting the tree processing head to the end of the boom. The rotator has a casing, that is non-rotatably mounted from the end of the boom, and a support shaft hat is mounted in the casing for rotation about its longitudinal axis relative to the casing and that supports the processor head at its lower end. Rotating means are provided on the rotator for rotating the support shaft relative to the casing. A first set of hydraulic lines extend from the boom to the casing and a second set of hydraulic lines extend from the support shaft to the processor head. Hydraulic flow paths extend through the rotator between the first and second sets of hydraulic lines.
