Abstract: A stone separation table (30,70) selectively separates and drops stones, clods, and dirt (27) between selected rollers while conveying potatoes (33) or other root crops from one side of the table to the other. The stone separation table incorporates sets of rollers (32,72) including separating (36,76) and spacing (40,80) rollers of substantially the same diameter. The sets of rollers are coplanar forming a planar conveying level (45,75) with all rollers driven in the same direction of rotation. The separating roller (36,76) is constructed with projecting elements, either projecting fingers (38) of a star roller (36) or bristles (78) of a brush roller (76) for receiving stones, clods, and dirt (27) for rotation downward and dropping in the separating passageway (42,82) between the separating roller (36,76) and spacer roller (40,80).
