A solids handling equipment rotary plough includes a metal body defining a pair of opposed spaced non-parallel elongate faces extending between a bottom and a top and from a first end to a second end of each opposed elongate face, the first end and the second end being spaced further from each other than the top and the bottom are spaced from each other providing each opposed elongate face with a length greater than a height. The opposed elongate faces are on opposite sides and facing away from a first imaginary vertical plane, each of said opposed elongate faces having at least two elongate major surfaces which are not co-planar, an upper, elongate, non-vertical, major surface being angled towards the first imaginary vertical plane to slope upwardly and a lower, elongate, vertical, major surface being angled in a horizontal plane so that the first ends of the opposed elongate faces are closer to each other than the second ends. The elongate faces are joined by a connector defining mounting means to mount the rotary plough to a rotatable grate component.
