Abstract: An apparatus is provided to facilitate sod destruction and decomposition by cutting and crushing primarily horizontal roots and rhizomes while leaving vertical roots uncut. Multiple gangs of colters are attached to a frame, the colter gangs are arranged in staggered relation with respect to each other. The staggered relationship of the colter gangs allows the apparatus to cut relatively narrow strips of sod. A method of operating the apparatus is provided in which the apparatus is operated across a sod field in a first direction to cut the field into long, narrow strips of sod. The apparatus is then operated across the same field in a direction relatively perpendicular to the first direction, cutting the strips of sod into small pieces.

Abstract: A clay surface scarifier includes a portable frame with a first axle and a second axle rotationally connected thereto. At least one scarifying blade, having a cutting edge orthogonal to the first axis, is attached to the first axle and rotatable therewith about the first axis. At least one scarifying blade, having a cutting edge orthogonal to the second axis, is attached to the second axle and rotatable therewith about the second axis. The axes of rotation of the first and second axles are intersecting.
