Abstract: An apparatus for irrigation includes an elongate pipe carried on support carriages at longitudinally spaced positions to move in transverse to its length. The pipe carries water dispensing arrangements spaced along the pipe each including a first nozzle and a second nozzle carried on arms projecting forwardly and rearwardly of the pipe so that the nozzles dispense together an amount of water required at the location of the ground aligned with nozzles. The first and second nozzles are arranged such that the first dispenses at a higher rate and both dispense water onto the portion of the ground sequentially at a rate which is less than an amount which exceeds the infiltration rate of the soil, so that a total rate can exceed the infiltration rate of the soil. The arms can be flipped in height between high crop position and low crop position.

Abstract: A kit for a wheel comprises a hub component in the form of an annular body defining a central opening for receiving a shaft on which the wheel is to be mounted, at least one outer rim component adapted to form a substantially circular periphery of the wheel and a plurality of spoke components adapted to interconnect the at least one outer rim component and the hub component with each of the spoke components being arranged at a respective angular position about the hub component. Each outer rim component is formable from a blank comprises a main body which defines an outer ground engaging surface of the wheel, a pair of strips consecutively attached to one end of the main body in a manner such that each strip is movable relative to the adjacent element about a transverse folding axis, so that the strips can be folded to define a peak projecting outwardly to form a wheel rim with fins.
