An electrically powered log splitter has a frame carrying a pair of mutually spaced fixed splitting components with a carriage mounted movable splitting component movable in opposite directions therebetween. A reversible electric drive motor is mechanically connected to the carriage to propel the carriage in opposite directions. A control switch is electrically connected between a power source and the drive motor. The switch has a first closed setting at which the drive motor is energized to move the carriage and its movable splitting component in one direction toward one of the fixed splitting components, a second closed setting at which the drive motor is energized to move the carriage and its movable splitting component in the opposite direction towards the other of the fixed splitting components, and a third normally open setting at which the drive motor is deenergized to halt movement of the carriage. An operating handle is provided to manually adjust the switch from its normally open third setting to either of its first or second closed settings. A shuttle rod is formed integrally with the operating handle and is engageable by the carriage to adjust the switch from either of its first or second closed settings to its normally open third setting in order to limit carriage movement in either direction. With minor modifications, essentially the same arrangement can be employed to operate a single-acting log splitter wherein the carriage mounted movable splitting component coacts with a single fixed splitting component.
