  • Patent number: 3935670
    Abstract: Apparatus for destroying selected plants by the application of electricity thereto. A source of high-voltage electrical current is mounted on a moveable platform, and a grounding wheel or the like is provided for insuring safety of the apparatus by grounding various electrical source components. A conductive tip portion of a non-conductive staff member may be connected to the source of current by a cord, and an operator controlled switch in a secondary control circuit is mounted on the staff member. The switch is normally open so that the conductive tip portion will not be energized should the operator release his grip on the staff member. By actuating the switch and bringing the tip portion into mere touching engagement with a plant stem, plant destruction may be effected.
