ABSTRACT:
A machine is provided for destroying plants with electricity comprising a tank adapted to hold electrically conductive liquid, an electrode for placing the electrically conductive liquid in the tank at high electrical potential, including a high voltage source of electricity; nozzles for spraying the electrically conductive liquid on plants to be destroyed; and a structure for grounding the high voltage source. Air pressure provided over the liquid in the tank provides the motive force for spraying, and pneumatically operated valves in line with the nozzles are provided for selectively supplying liquid to the nozzles. In this way, there are no moving parts which are electrically charged. Condition-responsive structures, responsive to plant position, are provided for controlling operation of the pneumatic valves, such as air limit proximity switches. The current output of the high voltage source is limited so that damage to the source is prevented, and the no-load voltage of the high voltage source also is preferably controlled.
