An off-centered concrete pulverizer linkage assembly adapted for mounting on an actuating arm of a vehicle. The linkage assembly comprises a coupler pivotally attachable to the actuating arm, a front jaw mounted on the coupler, a rear jaw, having a rear end section, pivotally connectable to the front jaw. The linkage assembly is activated by a single actuator comprising a telescopic arm slideable between a retracted position and an extended position. The actuator is pivotally attachable to the actuating arm and to the coupler to drive a coupled movement of both the front and rear jaws. Upon extension of the telescopic arm from the retracted position, the front jaw rotates and moves towards the rear jaw and, the rear jaw rotates and moves away from the front jaw. The front jaw reaches the rear jaw as the telescoping arm reaches the extended position. |
