An irrigation apparatus comprises a drive unit (C) which moves and guides the apparatus along a water supply pipe (B) having a plurality of hydrants (H) along its length. The drive unit (C) supports one end of a boom (F) the other end of which is supported by a powered wheel unit (K) which causes the boom to rotate about the drive unit (G). The boom (F) carries sprinklers (M) along its length and outwardly directed jets (N,P) adjacent the wheel unit (K). The sprinklers (M) and the jets (N,P) are intermittently operated so that as the boom rotates a substantially rectangular area is irrigated. The drive unit (C) has a hydrant coupling unit (A) and, after a given area has been irrigated from one hydrant the coupling unit (A) disconnects from the hydrant, the drive unit (C) moves the apparatus to the next hydrant and the coupling unit automatically couples thereto so that an adjacent area is irrigated. |
