Vibrating digger (rear discharge) Ursa can be mounted on small tractors equipped with the three-point suspension system of the I cat. The machine consists of a vibrating share with adjustable digging depth that transfers potatoes and soil onto the vibrating hopper sifting potatoes from the soil. The digging depth is adjusted by rear support wheels. Sifting intensity can be increased by adjusting inclination of the sifting hopper. All vibrating elements are moved by a crank mechanism driven from the tractor PTO shaft. Axes of the share and the sifting hopper are equipped with rubber bushings - simmerblocks which allow stability of the machine during operation. Its reduced dimensions enable to use the machine on small plots, flat and hilly areas.
