The device comprises a wheeled chassis having at least one drive wheel. A take-up arrangement on the chassis takes up a supply hose extending away from the device. Irrigation facilities are located on the chassis and are connected or connectable in fluid flow communication with the supply hose. - A differential drive transmission connects the drive to the drive wheel and to the take-up arrangement. Thus, in operation, drive is apportioned to the take-up arrangement for taking up the hose, and to the drive wheel for propelling the irrigation device in the direction in which the hose extends away from the device. |
