An enclosure is constructed as a back pack so that it may be worn. Air is conducted into an air intake chamber, then to an air intake plenum by air impeller. An electric motor is coupled with an air impeller, with motor cooling accomplished by the positioning of the electric motor adjacent to a motor cooling intake aperture. A sound absorbing layer lines the enclosure. Air exits through an air exhaust orifice for application in blowing leaves etc. A rotational transmission, terminating with a coupling is adapted for receiving an accessory for operation of the accessory so that a wide range of garden, carpentry and farming accessories may be utilized with the power take-off.
