Abstract:
1. A sprinkler, comprising: a turbine; a nozzle; a gear train reduction in a housing having at least a reversing planetary gear drive portion; a reversing control mechanism located outside of the gear train reduction that couples the gear train reduction and the nozzle and includes a pair of arc tabs, at least one of the arc tabs being adjustable to establish an arc of coverage of the sprinkler when water flowing past the turbine causes the gear train reduction and the reversing mechanism to oscillate the nozzle back and forth between a pair of arc stops defined by location of the arc tabs; and a mechanism located in the gear train reduction that allows manual rotation of the nozzle between the arc stops without having to back drive all of the gears in the gear train reduction.
