Abstract:
A device for cutting vegetation comprising:means for supplying water under pressure,means connected with the means for supplying for ejecting the water under pressure in a form of at least one jet of water in a direction and in the form so as to cut the vegetation directly with the jet,means for rotating said jet solely by force of the water, the means for supplying for ejecting the water under pressure and the means for rotating the jet including a rotating head mounted rotatably relative to a part that supports the head, the head being supplied with water under pressure along an axis, through a rotating coupling, and being provided at the head periphery with at least one nozzle through which a cutting jet of water is emitted, the cutting jet being emitted in a plane perpendicular to said axis and directly against the vegetation so that the vegetation is directly cut by the cutting jet, the head containing at least one water channel communicating with the nozzle, the nozzle having a nonradial orientation in said plane, so that, by mechanical reaction, the head and the cutting jet are caused to rotate, andat least one cutting cord affixed to said head to complement cutting work of the cutting jet.
