ABSTRACT:
Apparatus for breaking rock found in soil, such as in a field used for farming, includes a hood-like housing. A work shaft and a drum are positioned under the hood with the work shaft preceding the drum in the normal direction of movement of the apparatus. Flail-like parts are located on the outer surface of the work shaft and travel along a circular path. Prongs are provided on the drum and also move around a circular path. The circular path of the prongs is located lower than the circular path of the flail-like parts and at their closest point the circular paths are approximately tangent to one another where rock or other material is transferred from the prongs to the flail-like parts.
