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. A plurality of first 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 plurality 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.
