Abstract:
Mower comprising:a chassis,a connecting means allowing the chassis to be connected to a motor vehicle,at least one harvesting mechanism equipped with cutting members,a suspension device connecting the harvesting mechanism to the chassis and allowing said harvesting mechanism a heightwise movement with respect to said chassis,a lightening device associated with the harvesting mechanism and comprising two elastically deformable members extending transversely to a direction of forward travel during work, each elastically deformable member acting, via a first of its ends, on a corresponding end of the harvesting mechanism via a load-transmission member converting a transverse load created by said elastically deformable member into an upwardly-directed load at the harvesting mechanism,a centralized device for adjusting the lightening force exerted on the harvesting mechanism, said device being coupled to a second end of each elastically deformable member,wherein the centralized device for adjusting the lightening force exerted on the harvesting mechanism comprises a rotary control member connected to the chassis and coupled to each second end of the elastically deformable members via means which convert a rotation of said rotary control member into an action of stressing or relaxing said elastically deformable members depending on a direction in which said rotary control member is turned.
