Towed apparatus for excavating, pulverizing, and throwing soil to halt the spread of a forest fire. The apparatus comprises two series of rotating disks mounted to a first frame, each series driven by a hydraulic motor, for loosening the soil and pulverizing it into soil particles, followed by plowshares for funneling the resulting soil particles into a mound directly in the path of a spinner rotatably secured within a housing and having a plurality of fins attached thereto that scoop portions of the soil particles from the mound and throw them through a hole in the housing. Each disk in the series of disks has teeth secured about its peripheral edge for loosening the soil, pulverizing it and cutting and grinding roots, stumps and friable rock. The first frame is connected to a wheeled second frame by hydraulic cylinders to raise and lower the first frame with respect to the soil so that the series of disks can engage and be disengaged the soil to the depth desired.
