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.
