A portable timber felling device for controlled felling of a tree including a hydraulic ram unit positionable in a backcut of the tree for extension therein to fell the tree. A hydraulic power unit includes a pump and control valves to generate and regulate the hydraulic power required to operate the hydraulic ram unit. A hose means of a considerable length interlinks the power and ram units for the transmission of the generated hydraulic power. A remote control unit with a manually operable control member controls at least one of the valves on the power unit via a communication means which places the operator of the remote control at a substantial distance from the power unit and the tree to be felled. The entire structure is portable and a battery provides the electrical power for remote control.
