Abstract
This is concerned with an irrigation system or mechanism which is constructed and arranged and intended to water non-circular fields which may be considered polygonal sided intersecting at the corners. The system and method includes the use or combination of two types of irrigation systems, the first a so-called lateral move or free-standing span system and the second, either a so-called center pivot irrigation unit or a lateral move unit. The free-standing span moves along the outside of the field following the edge or border or fence with turns at intersections and the main irrigation unit moves inside of it and is coordinated and connected to it so that at times they overlap and at times they are distended with water, preferably, being supplied to the free-standing span by the main irrigation unit.
