Abstract: A method and apparatus for retrieving material, typically cotton, from the ground, comprising a main body, a rotating saw drum, a rotating brush drum, and a conveyor device. The main body is coupled to a large vehicle, such as a cotton picker. The saw drum has projections (or teeth) that collect the material from the ground as the saw drum rotates. The rotating brush drum, located inside of the main body and proximate the saw drum, removes the material from the saw drum and deposits it onto the conveyor device. The conveyor device then transports the material to a central area, where a suction tube removes the cotton to a storage volume.
