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.

I claim: 1. An air-powered rotary rake, comprising:a housing defining an open interior region, the housing having opposed open front and rear ends, the rear end being adapted for releasable attachment to a source of pressurized air;an internal wall disposed in a front portion of the housing, the internal wall and an interior surface of the front portion defining an upper passage and a lower passage, the internal wall further dividing the open front end of the housing into an open upper front end and an open lower front end;a spindle rotatably mounted within the upper passage of the front portion of the housing;a plurality of vanes extending radially from the spindle;a pair of retaining wheels respectively secured to laterally opposed ends of the spindle, the pair of retaining wheels being positioned external to the front portion of the housing;a plurality of rake members releasably attached to the pair of retaining wheels; andmeans for selectively diverting pressurized air flow between the upper passage and lower passage, whereby when the pressurized air is diverted into the upper passage, the pressurized air impinges upon the plurality of vanes mounted on the spindle, causing the spindle to rotate, rotation of the spindle driving rotation of the plurality of rake members.
