ABSTRACT An apparatus (10) for processing trees includes a hollow boom structure (12), a processing head (14) mounted for movement along the boom and an actuating cylinder assembly (38) which is mounted inside the boom structure. The cylinder includes a body member (50) and support means (52) engageable with the inside of the boom which support the body member for linear movement along the boom. A reeved cable system interconnects the actuating cylinder assembly with the processing head such that the actuating cylinder and the processing head move in opposite directions along the boom when the actuating cylinder is pressurized. In accordance with one aspect of the invention, the cylinder assembly includes opposed piston assemblies (40, 42) and means associated with the piston rod (54) of one piston assembly (40) for selectively transferring hydraulic fluid from a source to the head ends of both piston assemblies and to a central chamber (60) defined between the piston assemblies.
