A comminuting mechanism is disclosed that includes a rotatable drive shaft which supports a plurality of blades, each blade having both straight arms and arms having angled tip portions. The shaft and blades are supported on a frame within a hood, and the frame is pulled along a ground surface by a tractor or other vehicle. Debris is pulled into the housing by the combined action of the forward motion of the vehicle and an inward airflow generated by fan members on the rotating blades, pulverized by the action of the blades, and discharged through an outlet.
