ABSTRACT:
A corner watering circle move in which a line move and sprinklers thereon are stopped when the move comes to a corner portion of a field, an end section of the move then is swung to move a movable coupling member thereon into coupled engagement with a set coupling member, water then is supplied from the line through the coupling members to set sprinklers in the corner portion. After a predetermined sprinkling time, the line is cut off from the coupling sections, the sprinklers on the line are started, the end section is backed away from the set coupling member to a position aligned with the rest of the line and the movable coupling member is offset from the set coupling member, and the line move is moved to the next corner portion. The sprinklers on the line have differential pressure valve actuated by a pilot line on the line to control water supply to these sprinklers.
