ABSTRACT:
A fertilizer spreader includes an attachment assembly for use with a portable hand-held air blower for entraining granular fertilizer or the like into the discharge air stream of the blower, whereby the fertilizer is broadcast by the air stream over a lawn or garden area. The attachment assembly comprises an adapter nozzle connected in-line with the discharge air stream of the blower and including a pressure port through which a portion of the discharge air stream is directed for passage through a pressure tube to a diffuser mounted within a portable vented fertilizer-receiving container near the bottom thereof. The diffuser turns the air stream upwardly within the container and divides the stream into a plurality of turbulent air flows for agitating and suspending particles in a localized region above the diffuser, with a substantial portion of the air stream escaping from the container through a vent at a position remote from the localized region. The fertilizer particles suspended within the localized region are drawn into a downwardly open suction tube which is connected back to the adapter nozzle at a Venturi throat therein to provide a vacuum source for drawing the fertilizer particles into the blower discharge air stream for entrainment therewith. A bleed hole in the suction tube is partially closed by an adjustment collar to select the magnitude of the vacuum acting upon the suspended fertilizer particles for controlling the flow rate of particles into the blower discharge air stream.
