1. An apparatus for trimming and chemically treating vegetation, comprising:
- a saw arm having a top, a bottom, sides and ends;
a plurality of parallel saw blades affixed along a side of the saw arm for trimming the vegetation, wherein the saw blades each have an axis of rotation perpendicular to the side of the saw arm; and
a plurality of nozzles affixed in or to the saw arm for spraying a chemical treatment on the vegetation in the proximity of the saw blades, wherein the plurality of nozzles direct the chemical treatment generally parallel with the saw blades, and wherein the chemical treatment is blocked in part by the saw blades so that some amount of the chemical treatment is sprayed onto the saw blades,wherein the saw blades span above and below the top and bottom of the saw arm,wherein the nozzles are formed on the top and bottom of the saw arm, andwherein the nozzles are flush with the top and bottom of the saw arm.
