Abstract
A center pivot irrigation system comprises a plurality of mobile towers spaced apart and aligned in a row with an irrigation pipe extending between and supported atop the towers. The row of aligned towers pivots about a mobile pivot tower located at a water supply. The mobile pivot tower comprises a vertically disposed frame mounted on a pair of wheels. The frame and one wheel are mounted to pivot about the other wheel, and anchoring structure restrains the other wheel from moving during pivoting of the frame and one wheel.
