A fully automated irrigation system to irrigate regular and irregular shapes of land. The system includes a water delivery pipe assembly configured to travel linearly while irrigating adjacent to a stationary row of water main spaced access valves. The system includes an automated connector configured to supply water from the access valves to the water delivery pipe assembly. The connector includes a swing arm, a compensator, a valve coupler, a lift and a swinger. The swing arm facilitates positioning a coupler body above a next-up access valve and facilitates positioning the delivery pipe assembly. The compensator compensates for distance change between a coupled-to access valve and the delivery pipe assembly when the assembly travels. A coupler body resides at an outer end of the swing arm. The lift raises and lowers the swing arm to couple and uncouple respectively the coupler body along the row of access valves. The lift also holds the swing arm above the ground while the swinger swings the swing arm proximate to the next-up access valve for subsequent coupling the coupler body thereto.
