A particulate-incorporating attachment for a drop spreader is provided that includes a two-portion mount bracket, an implement holder, and a rake/brush. The bracket portions are connected to form a mount bracket over the rest brace of the drop spreader. The mount bracket mounts or carries the implement holder, which supports the rake/brush in a suitable position to assist in the incorporation of infill material into the space between the grass tufts of synthetic turf or to assist in the incorporation of other dropped particulates into synthetic or natural turf or onto the ground.
