Abstract: The invention employs a blower of the type used by commercial landscapers. The device has an engine mounted on a frame. Shoulder straps attached to the frame allow the user to wear the device on his back leaving the hands of the operator free to operate other tools such as a chain saw or perform other tasks. Also, wearing the device on the back makes it easier to transport the device over long distances to the source of the fire or backfire to be started. The device's blower generates a stream of air at high speeds. This stream of air can be used to feed a fire when the air is directed at a fire. When used to extinguish a fire, air from the blower is tapped from a point 180 degrees removed from the blower output and mixed with exhaust from the engine. This mixture is diverted through a Y-shaped valve into the airstream coming out of the blower. When the device is used to start backfires a fire is started.

Furthermore, the directional assembly includes a second (or shutter) plate that is secured to the first plate, the slidable movement of the second plate relative to the first plate regulating flow of granular material from the hopper to the fan.

Typically, the actuator comprises a grip around the pole that slides along the pole when exercised by an operator. A spray gun is normally attached to the pole proximal end with a trigger that regulates high-pressure fluid into the pole.
