Patent ID: 8369996

Claim:
A method of providing fluid to a field space, the method comprising the steps of: providing a main pipeline of a center pivot irrigation machine for irrigating at least a portion of the field space, the main pipeline including— a proximal end configured to operably couple with and rotate about a center tower, and a distal end opposite the proximal end; providing an auxiliary pipeline of the center pivot irrigation machine for irrigating at least a portion of the field space, the auxiliary pipeline including— a proximal end configured to operably couple with and rotate about the distal end of the main pipeline, and a distal end opposite the proximal end; and providing a control system for instructing the auxiliary pipeline to rotate about the main pipeline as the main pipeline moves through the field space in accordance with a defined routine, said routine allowing the auxiliary pipeline to rotate about the main pipeline while the main pipeline is moving, such that an angle between the main pipeline and the auxiliary pipeline ranges from less than 180° to greater than 180° so that the auxiliary pipeline both leads and lags the main pipeline as the main pipeline makes a progressive rotation in a single direction through the field space.
