ABSTRACT:
An automatic lawn treatment device includes a reservoir connected to a rotary type sprinkler for distributing a lawn treatment chemical at a controlled rate. A siphon nozzle in the reservoir mixes a liquid lawn treatment chemical with water from a supply source prior to distribution through the sprinkler. A graduated scale on the reservoir is provided for allowing a carefully measured amount of a treatment chemical to be distributed. A float actuated valve may be provided in the reservoir for shutting off the water flow after a predetermined quantity of chemical has been dispensed.
