Side walking irrigation system

摘要

A first steerable prime mover wheeled tower and a plurality of laterally spaced intermediate and end towers collectively carry a horizontal irrigation conduit which receives water through a hose dragged behind the prime mover wheeled tower. The irrigation conduit is supported by a truss structure extending between the tops of the several towers. Electric drive motors on the individual towers are powered in proper sequence to cause the intermediate and end wheeled towers to follow the linear path of the prime mover wheeled tower without appreciable lag. A system of control switches responds to tension in a control cable connected with a spring-loaded crank element on the prime mover wheeled tower to produce automatic activation of the control switches.
