1. An irrigation sprinkler rotor having a full-circle mode and a part-circle mode comprising:
a housing;
a riser movable between a retracted position and an elevated position relative to the housing and having a longitudinal axis;
a turret mounted for rotation relative to the riser;
a turbine-driven motor rotating the turret in a full-circle mode and a part-circle mode;
at least a pair of arc stops disposed in a first operational plane relative to the longitudinal axis and mounted for movement with the turret;
a shiftable transmission powered by the turbine-driven motor and operable to oscillate the turret in the part-circle mode between the at least a pair of arc stops;
a trip lever arranged to be shifted in an axial direction from the first operational plane to a second operational plane, the second operational plane spaced an axial distance from the first operational plane;
when the trip lever is positioned in the first operational plane, the trip lever is shifted by the at least a pair of arc stops to shift the transmission to oscillate the turret between a clockwise direction and a counter-clockwise direction in the part-circle mode;
when the trip lever is positioned in the second operational plane, the at least a pair of arc stops bypass the trip lever for rotation of the turret in the full-circle mode;
when in full-circle mode the turret rotates only in one of the clockwise direction or the counter-clockwise direction; and
a third operational plane intermediate the first operational plane and the second operational plane, at least a first portion of the trip lever positioned in the third operational plane during transition from the first operational plane to the second operational plane until being moved rotationally by one of the at least a pair of arc stops.
