Abstract: A water delivery machine for delivering water under pressure from a pressurized main line to a linear irrigation system, the main line having spaced risers therealong, and wherein the water is delivered continuously as the linear system moves over the field being irrigated. The machine has fore and aft articulated booms, the inner ends of which are connected to the water conduit of the linear system, and the outer ends of which are connected to couplers. The booms provide water conduits to deliver water from the couplers to the linear system. Each boom includes a conduit section extending generally in the direction of travel of the linear system which is supported on a wheeled cart having inner and outer wheel bogeys.
