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 deflection sensor is positioned on the extension boom for sensing vertical deflection of the extension boom which is caused by relative movement of the main boom with respect to the extension boom. A control connects the deflection sensor with the drive for driving the steerable drive tower upon the deflection sensor sensing a predetermined amount of deflection of the extension boom.
