  • Publication number: 20070201978
    Abstract: A blower unit is configured to have a forward containment portion for housing mechanical equipment for receiving and dispensing material particles as ground cover. A rear containment portion is provided for containing such material particles. A material mover preferably operable in forward and rearward direction will feed material to the mechanical equipment for breakdown and pneumatic disbursement. A rear door design enables convenient unloading of the material with the live floor directionally reversed. Benefits include a more convenient means for servicing of the blower mechanism including e.g. an engine providing a motor source, dispensing hose, rotary air lock feeder and mixing chamber e.g. T injector or dropout (term as used in the industry).
