Abstract
A method and apparatus for blending and transferring earth material at a blending site. The apparatus has a sinking shank mounted on the end of a boom of a working machine. Two cutter drums are mounted in spaced relation on the end of the shank for rotation about a horizontal axis. The working machine is advanced toward the blending site. The cutter drums are sunk into the earth material at the blending site and rotated to effect blending. The cutter drums are drawn toward the working machine to further effect blending and transfer a portion of the blended earth material to an accumulation of blended earth material over which the working machine advances.
