ABSTRACT:
An apparatus for cutting wood is disclosed wherein a trailer provides an operator station at one end and a plurality of components for automatically cutting and splitting wood into fireplace-sized pieces. A boom arm is controlled by the operator to load logs onto a log deck. The log deck includes two parts which may be telescoped together during transportation and extended to receive long logs during operation. Cams allow a single log to be loaded onto a set of rollers which advances the log into a cutting station. The cutting station includes additional rollers for engaging the sides of the log and driving it to a predetermined location. Then, the saw automatically cuts the log and the cut piece is released to fall into a splitting section. A sensor detects when the log is in the splitting section and a hydraulic ram is activated to split the log into pieces. The pieces then fall down a slanted plate onto a conveyor belt for loading into a truck. If it is desired not to split the wood, an intercepting chute is moved into a location between the cutting station and the splitting station to direct unsplit logs onto the conveyor. The apparatus is operated by an engine which drives a hydraulic pump to power a number of hydraulic motors which operate the various parts of the apparatus. Once a log has engaged the rollers associated with the cutting station, operation is essentially automatic, thus allowing the operator to obtain additional logs and place them on the log deck.
