An oscillating lawn sprinkler (4) has a spray pipe (7) pivotally mounted on a sprinkler body (5). The spray pipe (7) is driven to oscillate by water pressure through a motor mechanism disposed in a driving mechanism compartment (6). The driving mechanism compartment (6) is connected to a supply of water on one side thereof and with one end of the spray pipe (7) on the other side thereof. An adjusting mechanism is provided for adjusting the flow rate of water delivered by the spray pipe. Furthermore, a mechanism for adjusting the oscillating range of the spray pipe has a control member (9) disposed on the same side of the driving mechanism compartment (6) as a control member (26) of the water flow rate adjusting mechanism. Both the control members (9, 26) are disposed on the side of the driving mechanism compartment opposite to the spray pipe (7). A filtering mechanism is removably housed at a water supply inlet connection (8) of the oscillating sprinkler (4) for filtering the supply water.
