1. A log-splitter attachment tool adapted to be utilized with a mobile machine having a hydraulically articulating boom and dipper stick and an opposing thumb member secured to the dipper stick comprising:

  • (a) a body section, said body section releasably attached for pivotable movement to the dipper stick and hydraulic system of the machine or to a quick coupler mechanism attached to the dipper stick, said body section including a pair of parallel plates spaced apart so as to fit over an end of either said dipper stick or said quick-coupler mechanism, and(b) a blade section extending from the body section, said blade section including an elongated splitting blade, having a cutting edge, which when said tool is attached to the dipper stick aligned opposite said opposing thumb member, enabling a log positioned between the thumb member on one end and the splitting blade on the other end to be split by activating the controls of said hydraulic system to pivot the splitting blade towards the thumb member.
