Abstract
A sprinkler includes a turbine, a nozzle, a planetary gear drive and a reversing mechanism. The planetary gear drive and the reversing mechanism rotatably couple the turbine and the nozzle. The planetary gear drive includes a control shaft that is axially movable to shift a direction of rotation of an output stage that is coupled to the reversing mechanism. The reversing mechanism includes a shift member secured to an upper end of the control shaft. The reversing mechanism further includes a pivotable shift fork with a first cam and a second cam spaced from the first cam. The first cam is configured to engage the shift member and raise the control shaft when the shift fork is pivoted to engage the first cam with the shift member. The second cam is configured to engage the shift member and lower the control shaft when the shift fork is pivoted to engage the second cam with the shift member.
