ABSTRACT:
An irrigation machine having traction wheels which run along the top of a pipe having self-closing hydrants spaced apart in the length of the pipe. The machine is guided to follow the course of the pipe. When the machine reaches a hydrant, the machine stops and a vertically-movable riser pipe in the form of a probe and connected to a water gun or other water distribution device automatically descends to open the hydrant valve and thus admit water to the riser pipe and to the water gun. The machine is fitted with a device which shifts the machine longitudinally of the hydrant as the riser pipe is lowered towards the hydrant so that when the probe end of the riser pipe enters the hydrant, the probe end will be in precise vertical alignment with the hydrant. After a predetermined time the riser pipe is raised, the hydrant valve closes and the machine travels along the pipe to the next hydrant.
