Abstract
An irrigation sprinkler has a riser assembly that includes a rotatably mounted nozzle turret, a secondary nozzle holder removably mounted on the nozzle turret, and a turbine. A drive assembly is mounted in the riser assembly and couples the turbine and the nozzle turret so that pressurized water entering a lower end of the riser assembly will cause the nozzle turret to rotate. The nozzle turret has a primary nozzle and the secondary nozzle holder has at least one secondary nozzle.
