Abstract:
An irrigation system for conveying a fluid from a fluid source, said system comprising;a first irrigator span having a first end and extending to a distal end, a first drive system for moving said first irrigator span, a second irrigator span extending from said distal end of said first irrigator span, a second drive system for moving said second irrigator span, an alignment mechanism interconnecting said first irrigator span and said second irrigator span for maintaining alignment between said first irrigator span and said second irrigator span within a predetermined limit, said system characterized by one of said drive systems being variable speed and said alignment mechanism including a potentiometer for measuring the magnitude of misalignment between said first and second irrigator spans to vary the speed of one of said drive systems to realign said first irrigator span and said second irrigator span to maintain said predetermined limit.
