<p>A timber-working head (10) comprises a frame (20), first and second delimb arms (24, 25) pivotally coupled to the frame (20), a delimb cylinder (34), and delimb cylinder hosing (80). A torso (31 ) of the frame (20) comprises a box enclosure (78) and a hosing channel (79) extending through a cavity (93) of the box enclosure (78). The delimb cylinder (34) is mounted to both the first delimb arm (24) and the second delimb arm (25) and operable to pivot the first and second delimb arms (24, 25) relative to the frame (20) to open and close them. The delimb cylinder (34) is oriented in its longitudinal dimension laterally relative to the torso (31 ), and is positioned in front of and floatable laterally relative to the torso (31 ). The delimb cylinder hosing (80) is routed from the delimb cylinder (34) through the hosing channel (79). The hosing channel (79) expands laterally relative to the torso (31 ) as the hosing channel (79) extends along its length forwardly through the box enclosure (78).</p> |
