An apparatus for removing dirt and debris from clumps of down cotton that are released from slots of a group of retrieving belts as the belts pass around a rotating pulley that causes the slots to open includes a first group of approximately semi-circular, parallel tines disposed adjacent to the portions of the belts passing around the pulley. A plurality of fingers extending from the pulley and between the belts into the region bounded by the first group of tines and the belts urges the released clumps slidingly along the tines, and apply forces that loosen dirt and debris, which pass between the tines. The clumps ejected from the upper end of the region are received by pegs of a rotating peg drum and are moved against a second group of approximately semi-circular, parallel tines. The pegs tend to "thump" the cotton clumps as they slide along the second group of tines, further breaking up dried mud and debris therein and causing it to pass outward between the tines of the second group. Clumps ejected from the upper portion of the tines and the peg drum are conveyed to a cotton cleaner including a cleaning saw assembly "saw setting" bar, a kicker wheel, and a doffer-fan assembly for further cleaning of the clumps.
