Multi-mode rotor sprinkler apparatus and method

Abstract

A multi-mode sprinkler adjustable for part or full circle operation to irrigate a selected area is provided. The sprinkler includes a nozzle for dispensing fluid, a set of gears for rotating the nozzle, and an arc setting mechanism that cooperates with the set of gears. The arc setting mechanism comprises a fixed trip for switching to a first direction for the nozzle and an adjustable trip movable relative to the fixed trip for setting an arc of rotation for the nozzle in the part circle mode. The arc setting mechanism also includes a toggle for engaging the fixed trip and the adjustable trip to switch between a first direction and a second direction when in the part circle mode. In the full circle mode, the adjustable trip is deflected radially outward, and the fixed trip deflects radially outward as it passes the toggle, allowing continuous rotation of the nozzle. A memory arc function is also provided, in which the arc setting mechanism returns to an originally set arc of rotation after mishandling of the sprinkler.
