Abstract: Irrigation apparatus comprises a movable vehicle arranged to be steered along a required ground path and carrying a pair of laterally-extending booms each of which is pivoted to one side of a rotatable turret mounted on the vehicle chassis. Each boom carries spray or sprinkler nozzles spaced along their lengths and one or more spray nozzles at its tip, all connected to a supply of water, and the spray patterns of the various nozzles overlap one another in such a way as to ensure even total dosage of water delivered per unit area of ground as the machine advances. Means is provided for angularly reciprocating the turret and booms about the vertical axis of the turret. The vehicle may be connected by a trailing flexible hose pipe to a hydrant, or may have a power-driven hose reel on which the hose is wound and by which it can can be reeled in or unreeled whilst the vehicle is moving and with the hose either empty or delivering water. The flexible hose may also be of a longitudinally-seamed construction.
