Abstract (en)
A machine for splitting wood pieces comprises a splitting space (7) for the placement of a wood piece, a splitting head (3) arranged to move back and forth in the splitting space (7) and connected to an actuator, which is driven by pressurized medium and arranged to produce said movement, and a splitting blade (8) placed on the extension of the motion path of the splitting head (3) for splitting the wood piece (K). The splitting head (3) is connected to two actuators (1, 2) in parallel, and the working pressure of the pressurized medium is arranged to be coupled selectively to the actuators so that in the first coupling position, the actuators (1, 2) provide a higher total thrust force and a lower speed than in the second coupling position.
