The attachment comprises an elongate box-like trough commensurate in size with the size and shape of the slot. The receptacle portion of this trough is capable of trapping weed seeds and extraneous matter. One end of the trough is provided with a depending discharge spout. The side walls have outwardly flaring trough positioning flanges. An insertable and removable screen of suitable mesh is fitted and seated in the trough and hinged attaching straps embrace the housing and are detachably bolted in place.
