A portable, vehicle-towed cut-off saw for firewood and the like is herein disclosed for cutting down regular length firewood into pieces that can be used in a stove or smaller fireplace. The invention is mounted on a steel frame with two wheels and a trailer tongue that allows it to be towed by a vehicle such as an automobile, truck or all-terrain vehicle (ATV). The invention is powered mechanically by an on-board four cylinder gasoline engine which provides power via a series of belts and pulleys. The pulleys drive a large diameter circular saw blade which pivots from the bottom of a large feed table. The invention will cut wood up to 12″ in diameter with one pass. The saw blade is retractable, is protected by a guard, and is only exposed when cutting wood. The invention can be towed directly to the cutting or piling site and is easily moved and operated by one person. The use of the device allows for the cutting of firewood into smaller pieces using production cutting methods in a manner which is not only quick, easy and effective, but safer and less fatiguing as well.
