A weed electrocution system comprises a tool bar section comprising a central tool bar and one or more peripheral tool bars pivotable relative to the central tool bar. A mount is adapted to mount the tool bar section to a tractor. A first electrode is associated with the central tool bar, and a a second electrode is associated with the second tool bar. When an electric current is supplied to the first and second electrodes, the electrodes are able to electrocute weeds that come in contact with the electrodes. A ground wheel connected to a peripheral tool bar causes the peripheral tool bar and the second electrode to adjust to the contour of the land.
