A simple log splitter may be powered by an electric motor driving a hydraulic pump or by gasoline or diesel engine with or without a tractor. The non-electric versions can be used remotely where the splitter can be moved to the location of the cut wood source. Split logs can then be loaded into trucks, trailers or bulk bags.

No matter what the power source, a log splitter either uses a hydraulic piston to drive the log through a stationary blade or a rotating cone shaped screw mandrel that pulls the log up over a wedge. Some models have attachments that prevent the split logs from falling to the ground allowing the operator to reposition the logs quickly for a second pass on the log splitter. Some cone or screw splitters are mounted on steel platforms mounted on a 3-point linkage that allow the log to be repeatedly split into smaller pieces without putting the wood down and up again.
