A concrete pulverizer adapted for mounting on an arm of an excavator includes a lower jaw having a first pivot pin mechanism and a crushing surface. The crushing surface on this jaw is formed with concrete waste apertures. An upper jaw has a rear end section connectible to an end of the arm and has crushing teeth mounted on a lower side. This jaw is pivotably connected to the lower jaw by the pivot pin mechanism. The upper jaw is pivotably connected to a hydraulic cylinder actuator on the arm and can be pivoted between an upper position and a crushing closed position. There is a power mechanism for pivoting the lower jaw between a horizontal scooping position and a dumping position and this mechanism can hold the lower jaw in a crushing position while the upper jaw is being pivoted by the hydraulic cylinder actuator.
