A wheeled saw for making random cuts in which a rotary saw blade is mounted between the spaced rear wheels of a carriage and having a pivotal forward wheel whereby relatively large movements of the front of the carriage effects relatively small movements of the saw blade enabling the blade to follow random cracks such as would appear in concrete and asphalt. An engine for operating the saw blade is mounted on the carriage and is vertically movable to raise or lower the saw blade from or to a cutting position and to bear on the blade when it is in a cutting position.
