ABSTRACT:
A linear irrigation system has the wheels on each end angled outward to stretch the entire pipe. Some of the vehicles in the middle of the pipe are steered responsive to the distance the elongated pipe is from a guide line. Steering is controlled by the movement of a cable. Bridges upon a tube on the cable are used to activate a microswitch. The microswitch itself is on a carriage which is responsive to the distance of the elongated pipe from a guide line. Therefore when any correction is needed, a predetermined correction is applied and no additional correction is applied until the carriage carrying the microswitch is again moved. The wheels are individually steered. The correction is almost instantaneous and is not dependent upon changing the angle of the entire moving pipe.
