A topsoil separating and spreading apparatus includes a grate and rotor assembly that can be pivotally mounted on the top of a standard loader bucket for operation. The spreader member includes an arcuate grate formed with slotted openings and a rotor rotatably mounted concentrically with the arcuate grate so that disks mounted on the rotor shaft will move adjacent to the arcuate grate to push topsoil through the grate openings. The spreader member is pivotally movable between opened and closed positions and is powered by the prime mover. The opening of the spreader member allows a supply of topsoil to be loaded into the bucket loader, after which the spreader member can be closed against the bucket to force topsoil to be discharged therefrom through the grate openings. The rotor breaks up clumps within the bucket, while the grate prevents the discharge of non-frangible debris from the supply of topsoil.
