Corner system addition for a center pivot irrigation system

An apparatus which is useful with an irrigation system having a center pivot boom which includes a primary water conduit and which in operation moves about a center pivot point, the center pivot boom being divided into a plurality of sections which pivot relative to each other, the apparatus comprising:

• corner boom means, which includes a secondary water conduit, joined to the outermost end of said center pivot boom in a pivoting relationship thereto;
• means supporting said corner boom means;
• means for moving said supporting means and hence said corner boom means about the outermost end of said center pivot boom in response to a signal command;
• first means for determining the angle between (a) an imaginary reference line, which is a straight line connecting the center pivot point and the outermost end of the center pivot boom, and (b) a fixed reference line having a known position relative to the irrigation area over which the center pivot boom moves;
• second means for determining the angle of said corner boom means relative to the imaginary reference line;
• means using the information from said first and second angle determining means to determine the position of said corner boom means relative to the irrigation area;
• and
• means supplying signal commands to said moving means when said corner boom means is in a selected position relative to the irrigation area.
