A rotary sprinkler includes a sprinkler body having a center axis and including a nozzle and associated rotor plate for issuing a stream in a substantially radial direction, substantially perpendicular to the axis, and rotating the stream about the center axis; a stream interrupter mounted loosely for eccentric rotation about the center axis, the stream interrupter including an annular ring provided with a plurality of stream deflector fingers, the stream interrupter being driven directly by the stream impinging on the plurality of stream deflector fingers. The rotor plate is formed with a stream emitting groove configured to receive a vertical stream and redirect the stream in the radial direction while also causing the rotor plate to rotate about the center axis. In addition, the groove is profiled to cause the stream to issue from the rotor plate with a primary component and a secondary component diverging from the primary component. This split stream interacts with the stream interrupter to provide greater radius of throw and uniformity characteristics.
