Abstract
The disclosure relates to irrigation machines of the type provided with a hose reel rotatably mounted on a wheeled frame. One end of the hose, fixed to the hose reel, is connectable to a water supply source and the other to a sprinkler gun. The hose reel is coupled to a drive motor designed as a water turbine. The water turbine is coupled into the conduit system of the machine via a flow-divider which is in the form of a three-way valve with one inlet and two outlets, the water turbine being coupled in between the two outlets.
