A mobile watering apparatus has a framework which is provided with wheels and supports a watering nozzle as well as a drum forming rotary magazine for a pipe, one end of which is connected to the nozzle. The other end of the pipe, leaving the drum, is adapted for connection to a water supply station on the land. A hydraulic motor, actuated by water under pressure, allows the traveling of the apparatus and the joint winding of the pipe on the drum, with however, a slip clutch in the second case. This slip clutch is preferably controlled by a means responsive to the tension being exerted on the pipe.
