An irrigation sprinkler can include a reversing mechanism configured to transition the nozzle turret of the irrigation sprinkler between a forward direction of rotation and a reverse direction of rotation. The reversing mechanism can include shifting frame having an input gear and at least one output gear. The at least one output gear can be mounted on an axle of rotation which permits lateral movement of the at least one output gear between a power transmitting position, wherein rotational power from a gear reduction is transferred to the nozzle turret, and a disengaged position wherein rotational power from the gear reduction is not transferred to the nozzle turret.
