Abstract
A machine and method for destroying plant growth. A specialty application is provided for plant growth around and between railroad tracks, and a general description is provided for preventing damage to the high voltage source of electricity used for the plant destruction, and for minimizing the number of fires started in dry material accessory to plant destruction. A vehicle with a high voltage electricity source is mounted on railroad tracks, with wheels of each wheel set for the vehicle being electrically isolated, and the high voltage source being grounded through one of the wheels. Special plant contacting devices comprising rounded end generally cylindrical contacting members are provided. The current output of the high voltage source is limited to prevent damage to the high voltage source, and the no-load voltage of the high voltage source is held to generally the same level as the full-load current limited voltage to minimize the number of fires started by the plant contactors.
