ABSTRACT:
The air-powered rotary rake is an attachment for a leaf blower or the like, providing the user with air-powered rotary blades to dislodge or agitate debris which, ordinarily, could not be moved easily with air blowing alone. The air-powered rotary rake includes a housing defining an open interior region and having opposed open front and rear ends. The rear end is adapted for releasable attachment to the leaf blower. An internal wall is mounted within a front portion of the housing and divides the housing into an upper passage and a lower passage. A spindle is rotatably mounted within the upper passage and a plurality of vanes are mounted on the spindle. When the pressurized air is diverted into the upper passage, the pressurized air impinges upon the vanes mounted on the spindle, causing the spindle to rotate and driving rotation of a plurality of blades also annularly mounted thereto.
