ABSTRACT:
Apparatus for distributing yard care material is disclosed using a yard blower having a hand held blower tube. A dry material feed system is affixed to a tube section of the blower tube which introduces dry material into an air flow generated by the blower by a feed opening formed in the tube section. An injection gate controls the amount of dry material dispensed from the feed hopper into the air flow. By using a slopping wall, a gravity feed of the dry material is made possible. Additionally, a liquid feed system may be provided which is secured to the dry material feed hopper to feed a liquid yard treatment material also by gravity feed. Advantageously, a liquid feed conduit is formed on the exterior of the blower tube and has an outlet end disposed a distance from the air exit end of the blower tube so that the liquid is injected into the air flow as it exits the blower tube for atomization and distribution to a treatment area. The apparatus may be provided integral with a special tube section which can be sold and interfitted with a blower tube of an existing or new yard blower.
