Abstract:
To allow for optimal uniform application of irrigation fluid in a field space outfitted with a center pivot irrigation machine having a main pipeline and an auxiliary or corner pipeline, the auxiliary pipeline is operable to both lead and lag the main pipeline as the main pipeline makes a progressive rotation in a single direction through the field space. In one embodiment a control system for the irrigation machine comprises a buried cable control system. In another embodiment a control system comprises a global positioning satellite control system. In a third embodiment a control system comprises at least two position sensing devices, a first device for sensing an angle of the main pipeline with respect to a center tower and a second device for sensing an angle between the main pipeline and the auxiliary pipeline, and a speed controlling device for controlling a speed of rotation of the main and auxiliary pipelines.
