Abstract:     This invention resides in a log splitter attachment for garden tiller, a unique bearing arrangement for same, and the combination of a garden tiller and such an attachment. The attachment includes a rigid ground engaging base frame having means thereon to support the tiller tine shaft of a garden tiller and a log to be split. Preferably the base frame will also support the garden tiller itself when used with the log splitter attachment. An auger is provided and is mounted on a shaft adapted to slip over one end of the tiller tine shaft. The auger shaft is secured to the tiller tine shaft and supported in a bearing member which is affixed to the base frame. The other end of the tine shaft is engaged within a spacer located in a corresponding bearing member and the spacer is attached to the tine shaft. Preferably the bearing members for the tine shaft are slotted just enough to receive the tine shaft but not the auger shaft or spacer; these enter the bearing member axially thereof and cannot pass through the slots. The auger extends to one side of the base frame. A log holding member is fastened to the base frame and extends to the same side as the auger, being spaced from but parallel to such auger. When the tiller motor is actuated so as to drive the tiller tine shaft, the auger and auger shaft will rotate therewith. The operator then moves a log, supported at one end on the log support, into contact with the auger whereafter the auger screws itself into the log to split it open.
