ABSTRACT:
An irrigation system is disclosed which includes a center pivot support having an elongated main water boom pivotally connected thereto which extends outwardly therefrom. An elongated extension boom is pivotally connected at its inner end to the outer end of the main boom and is supported by a steerable drive tower. A corner arm sensor is provided for sensing the angle of the extension boom with respect to the main boom. First and second lines of sprinklers are provided on the main boom along the length thereof with the nozzle size thereof increasing from the inner to outer ends thereof. A third line of sprinklers are positioned on the extension boom along the length thereof, the nozzle size of which increases from the inner end of the extension boom to the outer end thereof. A fourth line of second sprinklers are also positioned on the extension boom along the length thereof, the nozzle size of which increases from the outer end of the extension boom to the inner end thereof. By utilizing the two lines of sprinklers in combination, the proper amount of water can be applied for all corner arm positions. The flow rate in the first and third lines are equal and the flow rates in the second and fourth lines are equal. When the third line of sprinklers is activated, the first line of sprinklers is deactivated. When the fourth line of sprinklers is activated, the second line of sprinklers are deactivated.
