Abstract: A spray irrigation apparatus including a vehicle which carries a spraying nozzle connected to a hollow shaft of a drum reel, a pipe being connected to the hollow shaft and being wound onto the drum reel. The pipe is dispensed from the reel by means of a reeling guide structure which causes the pipe to move from the reel in a curved path so that the pipe passes from a direction perpendicular to the axis of the reel to a direction parallel to the displacement of the apparatus. That end of the pipe which extends from the apparatus is connected to a water supply station so that the apparatus is supplied with water for spraying onto a field or the like. According to a further feature of the invention, the axis of rotation of the drum reel extends along the direction of movement of the apparatus.
