ABSTRACT:
An apparatus attachable to a center pivot irrigation system provides for the raising and lowering of all sprinkler heads simultaneously. The apparatus includes a bar along the length of the system rotatably mounted in brackets attached to the bottom of the existing water supply pipe. Cables from each sprinkler head are wound around and fixed at the other end to the bar, and if several towers are arranged in a line, the bars are joined together with flexible spring couplings to transmit the torque from one bar to the next smoothly even if they are somewhat misaligned. Flexible hoses are used between the sprinkler heads and the water supply line to allow them to lift vertically upwardly or downwardly as the height is adjusted, and such height adjustment is accomplished by rotating the bar to either wind or unwind the sprinkle head support cables as desired.
