Abstract
A sprinkler includes a drive mechanism mounted in a riser that rotates a nozzle at the top of the riser. The drive mechanism enables a user to select between oscillation of the nozzle through an adjustable arc and uni-directional full circle rotation of the nozzle. The sprinkler includes an automatic arc return feature that enables the nozzle to resume oscillation between a pair of original pre-set arc limits when the nozzle is twisted by a vandal outside of the arc limits.
