Along the surface of a drum are a plurality of spaced-apart spike arrays with a plurality of aperture arrays interposed therebetween. A door at one end of the drum allows for deposit of granular materials, such as grass seed, within the drum. A paddle array within the drum is rotatable therein so as to open or close selected apertures of the aperture arrays. Upon drum rotation, as urged by the user on the handle assembly, the spikes first indent the earth with the grass seed then falling through the open apertures and into and between the resulting indentations in the earthen surface therebetween. The smooth surface of the drum then tamps the deposited seeds into the earthen surface. The spikes are preferably releasably attached to the cylindrical drum so that various types of spikes can be used. | ||||||
