Unitized sprinkler assembly including a housing assembly having an inlet end constructed and arranged to be connected with a source of water under pressure and a spaced outlet end, a manually adjustable control mechanism carried by the housing assembly, a sprinkler head assembly having an inlet end disposed to receive water under pressure flowing from the outlet end of the housing assembly, a base assembly constructed and arranged to support the assemblies on a ground area to be sprinkled, a structural connection between the sprinkler head assembly and the housing assembly constructed and arranged to enable the sprinkler head assembly to oscillate about an oscillatory axis with respect to the housing assembly, an oscillating mechanism mounted in the housing assembly constructed and arranged to be operated by the flow of water under pressure and connected with the sprinkler head assembly to oscillate the sprinkler head assembly about the oscillatory axis through repeated oscillating head cycles, an adjusting mechanism constructed and arranged to enable the distance of the head stroke of each oscillating head cycle to be adjusted within a range between a minimum head stroke distance and a maximum head stroke distance, and a control member to control selectively the width of the spray patter discharged from the sprinkler head assembly. The housing assembly may include first and second housing assemblies.
