A fully automated irrigation system to irrigate regular and irregular shapes of land. The system includes a water delivery pipe assembly configured to travel laterally while irrigating adjacent to a stationary row of spaced access valves supplied by a water main. The system includes a single coupler automated connector configured to supply water to the water delivery pipe assembly. The connector includes a swing arm mounted to and hydraulically connected to the water delivery pipe assembly. The connector includes a valve coupler mounted to the swing arm, the valve coupler configured to raise and lower relative to the swing arm to selectively access water from the water main via the spaced access valves. The connector includes a swing arm length regulator enabling substantially horizontal coupler travel relative to the swing arm. A water conveyance of the connector operably flows water between the valve coupler and the swing arm and maintains connection between the valve coupler and the swing arm during the raise, lower and horizontal travel of the coupler.
