<p>Watering apparatus (10) includes a chassis (12) and a sprinkler head (20) rotatably mounted for rotation about an axis of rotation (16). The sprinkler head (20) includes a pair of reaction outlets (26) spaced from the axis of rotation (16) and directed so as to cause rotation of the head (20) about the axis of rotation (16) when water is discharged therefrom. The sprinkler head (20) is connectable to a pressurised supply of water by means of a hose pipe (78). The apparatus (10) includes a pair of wheels (52) mounted on the chassis (12) and configured such that, in use, when driven they serve to propel the watering apparatus (10) along the ground. Drive from the rotating sprinkler head (20) to the wheels (52) is via a gearbox (13). At least one bleed opening leads from the head (20) to permit the volume of water flowing through the outlets (26) and hence the speed at which the apparatus is driven to adjusted.</p> |
