Abstract
A gear driven sprinkler head with a pop-up spray nozzle driven by a water-flow powered motor. The nozzle is rotated incrementally through an adjustable arc to irrigate a sector of a particular size, and it is automatically reversed at the end points of the selected irrigated sector. The nozzle may be interchanged with other nozzles to provide matched precipitation rates for sectors of different sizes. The feature of incremental rotation of the nozzle overcomes the problem of reduced throw distance at high rotational speeds encountered by the prior art assemblies of the same general type.
