Abstract: A linearly movable irrigation system, according to the present invention, may include a plurality of interconnected power driven irrigation sections supporting a water supply conduit which sections are capable of moving over a land area and depositing a controlled amount of water thereon. At one extremity of the irrigation system may be provided a mobile power and control unit that accepts water from a water supply system and conducts it to the overhead irrigation pipe under sufficient pressure to cause proper distribution of water through sprinkler devices located along the length of the irrigation conduit. A power driven pump may be supported by the power and control unit in order to pressurize or provide boosting pressure for the water received from the water supply. The power and control unit is adapted to move in proximity to an elongated reference which may be straight or curved as desired. The power and control unit is provided with means for sensing linear displacement and angular relationship thereof relative to the reference and for inducing control signals to the irrigation system that maintains linear displacement and angular misalignment of the system within an acceptable range. Each extremity of the irrigation system may remain static while the other moves or while interior sections thereof move in order to maintain movement of the irrigation system along a substantially linear track. The extremities of the irrigation system may also move simultaneously at equal speeds or at different speeds to accomplish controlled movement during irrigation operations.
