  • Patent number: 12280519
    Abstract: A log splitter includes a chassis having a support table configured to support a log to be split, a splitter screw having a generally conical shape and mounted to a rotatable screw shaft that is supported by the chassis, and a drive assembly configured to rotate the shaft to impart rotational movement to the splitter screw about a screw axis. The drive assembly includes a motor coupled to the screw shaft via a constant velocity transmission (CVT) (also known as continuously variable transmission). The CVT can provide both high speed and high torque during the splitting process as required to split the log. A fall restriction bar helps restrict a person from accidentally falling onto the splitter screw. An engine-kill bar is pivotally mounted to the chassis. A log-rotation stop mechanism is configured to restrict rotation of a log that gets stuck on the splitter screw.
