Abstract: A log splitter (1) for coupling to a dipper arm (2) of an earth working machine comprises a support element (3) and an anvil (5) extending perpendicularly from the support element (3). A splitting element (6) is slideable longitudinally along the support element (3) from a receiving state spaced apart from and defining with the anvil (5) an open mouth (9) for receiving a log, and a splitting state adjacent the anvil (5) for splitting the log. A primary ram (7) coupled between the splitting element (6) and a mounting bracket (20) extending from the support element (3) urges the splitting element (6) between the receiving and splitting states.
