A dual cutter head, self contained mower (30, 200) is provided for cutting vegetation beneath and on opposite sides of guard rails or cable barriers, and on opposite sides of rows of small trees, hedges, walls or fences. The cutter heads (52, 53 and 252, 253) are staggered to cut overlapping swathes and are adjustably biased to permit the cutter heads to move laterally away from one another when an obstacle is encountered. The outer cutter head (53, 253) can be swung to an overhead position to avoid road signs, poles or the like. The mower can be front or rear mounted and can be reversed to cut at either side of the supporting vehicle. A spray system (323) applies herbicides or other liquids to the area being mowed.
