  • Irrigation system with variable speed drive system
    Patent number: 6755362
    Abstract: An irrigation system for conveying a fluid is provided. The irrigation system comprises a first irrigator span having a first end and extending to a distal end. A first drive system moves the first irrigator span. A second irrigator span extends from the distal end of the first irrigator span. A second drive system moves the second irrigator span. An alignment mechanism interconnects the first irrigator span and the second irrigator span to maintain alignment between the first and second irrigator spans within a predetermined limit. One of the drive systems is variable speed and the alignment mechanism includes a potentiometer for measuring the magnitude of misalignment between the first and second irrigator spans. The potentiometer is used to vary the speed of one of the drive systems to realign the first and second irrigator spans to maintain the predetermined limit.
