ABSTRACT:
A backfilling machine having an auger with two spaced apart flighting segments thereon. One of the flighting segments has right hand flighting and the other of the segments has left hand flighting. The segments are rotated in unison so as to propel material from the side of the trench inwardly toward the space between the two flightings which space is aligned over the trench so that the filling material falls into the trench by gravity. The flightings are adjustably mounted on a central shaft for movement toward and away from one another to accommodate trenches of varying widths.
