Summary:An improved adjustable arc sprinkler head (2) includes a pop-up riser (20). Riser (20) comprises a housing (26) having a rotatable nozzle assembly (28) carried adjacent the top thereof. A driven gear (50) is fixed to nozzle assembly (28) and cooperates with a drive train contained inside a motor compartment (30) in riser housing (26). An adjustment member (58) is normally rotatably locked to driven gear (50) by matching serrations (69) and (70). Nozzle assembly (28) is moveable downwardly relative to riser housing (26) sufficiently far to disengage serrations (69) and (70) and allow driven gear (50) to be rotated relative to adjustment member (58). This rotation varies the circumferential distance between two stops (56) and (64) carried on driven gear (50) and adjustment member (58) to vary the angular extent of the arc segment being watered by sprinkler head (2).
