Abstract
This is concerned with a so-called center pivot irrigation system in which a string of pipe is supported on wheeled towers at intervals and pivots about a so-called center pivot or water supply either intermittently or continuously so that it waters or irrigates a generally circular area. This is more specifically concerned with an arrangement and a control for watering the corners or noncircular area of a field in a manner which is greatly simplified over a number of previous approaches.
