Abstract: This Power air blower fan head mobilizer of matted vegetation solves the problem of blowing leaves and other debris matted together by wind or rain. A flexible serrated mobilizer probe (composed of metal, plastic, or composite) is inserted into the terminal fan head air nozzle of an air or leaf blower in such a way that a mass of often wet debris is stirred, tossed, moved, and cut. Thus, the invention opens pathways into the matted mass so that airflow is effective. The device includes a curved sharp terminus, which acts as a vegetation cutter on both flat and irregular surfaces. Large stemmed vegetation and small limbs can also be sawed in two because the probe has coarse and fine serrations on its respective lateral sides. In addition, the 5 inch projecting curved probe terminus provides a spring skid to reduce weight of the power air blower, thus saving energy of the operator.
