splitter

A log splitter is a piece of machinery or equipment used for splitting firewood from softwood or hardwood logs that have been pre-cut into sections (rounds), usually by chainsaw or on a saw bench. Many log splitters consist of a hydraulic pump or electric motor which then powers a hydraulic or electrical rod and piston assembly. Generally, these are often rated by the tons of force they can generate. The higher the force rating, the greater the thickness or length of the rounds that can be split. The log splitter consists of all four major hydraulic components.
Most log splitter models for home use have a rating of around 10 tons, but professional hydraulic models may exert 30 tons of force or more. There are also manual log splitters, which use mechanical leverage to force logs through a sharpened blade assembly; and screw or 'corkscrew' types that are driven directly from an agricultural tractor's power take-off shaft where the splitter is mounted on the three-point hitch.
