ABSTRACT:
A linear move irrigation system and control therefor for use in irrigating large land areas including a water conduit extending over a portion of the field and supported on a series of support towers, the entire conduit being made to move down the field to be irrigated. A control system for controlling the movement of the irrigation system along a defined path and so as to maintain the wheel tracks of the conduit support towers generally parallel to the path. The control system includes a sensor located somewhere along the water conduit for sensing when a point located forward of the conduit relative to its direction of travel, is off the defined path. The movement of outwardly located towers near opposite ends of the conduit are automatically controlled in response to predetermined displacement of the point relative to the path, said towers being preferably located at opposite ends of the conduit, so as to maintain the point over the defined path, and further to maintain the wheel tracks of the conduit support towers generally parallel as the system moves over the field. The controlled towers near opposite ends of the conduit are normally driven when the point is on the path.
