<p>Watering machine. A carriage (1) provided with wheels (111) and (121) carrying an axial reel (3) on which is wound a hose (31). Connected by the reel shaft to a connection (20) towards a watering device, this hose goes through a reeling device (40, 41) carrying a hinged arm (44) capable of a symmetrical travel about the vertical. A caming device (46) detects the position of the arm (44), and a logic control (90) acts in response to the detection effected by the cams to control the winding or unwinding of the hose. Application in particular to irrigation of extensive surfaces. </p> |
