ABSTRACT:
An articulated saw chain for cutting aggregate material and the like. The saw chain has cutting blocks affixed to pairs of side links and guards formed or attached to side link pairs positioned between successive cutting blocks. A guard portion is thus adjacent each end of the cutting block. The guard portions extend to substantially the same height as the cutting block to protect the edge of the cutting block from impacting against an object. The guards wear at a rate that does not significantly impede or interface with the cutting action of the cutting block.
