PROBLEM TO BE SOLVED: To obtain a hydraulically-operated lumbering device for wood splitting interlocking with a hydraulic system driving. SOLUTION: In this device, a wood pinching fitting 4, which is connected with a sliding shaft 2 mounted through the tip fitting 14 of the piston rod of a hydraulic cylinder fixed to the interior of a hollow shaft frame, is installed on the shaft frame 1. In addition, a replacement cutting die 10 is installed to a change cutting blade frame 7 fixed onto the top surface of the shaft frame 1. A hydraulic directionally controlling valve and a movable engine-driven hydraulic unit device are connected by a hydraulic cylinder 13 internally fixed to the hydraulically-operated wood splitting lumbering device and with hydraulic piping. As the hydraulic piping between devices, which constitute no integral body, high pressure rubber hose piping is used for connection.
