Abstract
A lateral move irrigation system more effectively irrigates a field by minimizing the portions of the field that receive no irrigation. The irrigation system includes a plurality of mobile towers, a plurality of elongated support structures attached to and extending between the towers, and a fluid delivery system. Each mobile tower has wheels and a motor for driving the wheels. A safety circuit stops the motors on all the mobile towers when any of the towers reaches an end-of-run position. Location determining components determine locations of the mobile towers as they traverse a field, and a control system stops or slows any of the towers before they trigger the safety circuit so that lagging mobile tower may catch up before the safety circuit shuts down or reverses all the motors.
