Abstract: There is disclosed a self-propelled lawnmower wherein the wheels are mounted on a fixed frames surrounded, at least on its two lateral faces, by fixed protective skirts which extend practically to ground level. A cutting assembly is mounted on a secondary chassis which can be displaced with respect to the fixed chassis supporting the wheels. A linkage between the two chassis is provided by tilting levers that pivot on the fixed chassis and allow the secondary chassis to be vertically displaced thereon. Movement is transmitted to the drive wheels by a drive gear that engages a ring gear arranged inside each drive wheel, the drive gears being displaceable along the pitch circles of the ring gears when the secondary chassis is displaced.

Abstract: Device for cutting, picking up, and for temporarily storing grass or similar products with a view to transporting the stored product to a site for further processing. The device is integrally mounted to a vehicle so that it may be moved over an area of grass to be cut. The device includes a cutting head to cut and to take-up the lawn clippings. The cutting head is connected to first and second transfer pipes utilized to direct the cut grass to the interior of a storage enclosure. A turbine is horizontally mounted under the storage enclosure between the first and second transfer pipes and is dissociated from the cutting head. The turbine provides suction inside the first pipe so that cut grass may be moved from the cutting head toward the turbine. A turbine wheel with blades moves the cut grass tangentially into the second pipe which is integrated with the storage enclosure so as to direct the flow of cut grass into the enclosure.
