Lawn sprinkler incorporating a novel water distributing head having a "wobbling" motion. The base of the head is mounted loosely between shoulders near the end of a tubular water-supplying support arm. A water jet emerging from a nozzle at the end of the arm strikes internal vanes at the discharge end of the distributor head to cause the wobbling action. The support arm is journaled within a vertical bearing, and the action of the water jet causes the arm to be driven slowly through a circular path.
