ABSTRACT:
An irrigation machine guided to follow the course of a water supply pipe laid along the ground to be irrigated and having self-closing hydrants spaced apart along the length of the water supply pipe. The machine carries a vertically-movable riser pipe leading to an irrigation nozzle on the machine and arranged to be engaged automatically at its lower end to each of the hydrants in succession as the machine moves along the water supply pipe and stops with the riser pipe in vertical alignment with a hydrant. When the machine has stopped at a hydrant the riser pipe is automatically lowered to engage and to open the hydrant to admit water to the irrigation nozzle. The machine is supported on running wheels travelling along the top of the water supply pipe. To enable the wheels to pass over the hydrants without risk of the machine tipping over, the wheels are carried on a sub-frame which is pivotally-mounted about a horizontal axis on a main frame carrying the riser pipe and the irrigation nozzle.
