  • Ground release irrigation system
    Patent number: 4429831
    Abstract: An irrigation system is provided wherein a conventional central pivot spray-type system is converted into a ground release system through the use of a plurality of flexible hoses that release the water at ground level. A plurality of perforations at the distal end of the hose provide a spray effect without the water evaporation loss associated with conventional spray systems. Braces also prevent the hoses from swinging sideways and becoming entangled.
