Abstract
A water-propelled prime mover in and for agricultural irrigation systems. The hose to be coupled to and pulled by the prime mover, to supply water under pressure for irrigation purposes, also supplies water pressure for torquing the wheel line of the irrigation system and for advancing the prime mover, through its capstan revolvement, along an anchored cable, stretched over an intended course of travel. Means are provided to sense and utilize deflections of the wheel line, and also to control prime mover propulsion and wheel-line torque; further, to relate and vary the relationship of wheel line revolvement and prime mover advance, depending upon line conditions, so that the line and prime mover travel in proper mutual orientation.
