ABSTRACT:
A shredder head, and a mobile apparatus including the same, for carrying out various sylvicultural applications, such as land clearing and the like. Each of the shredding assemblies of the shredder head includes a protective element also operatively connected to the rotor for rotating therewith along the given direction of rotation, the protective element extending along the respective plane of its corresponding shredding assembly and defining a peripheral radius of action with respect to the axle when the rotor is rotated about the axle, the protective element being positioned upstream of and being aligned with the shredding knife during rotation of the rotor, and the peripheral radius of action of the protective element being substantially identical to the peripheral radius of action defined by the cutting edge of the shredding knife so that said shredding knife is protected by the passage of the protective element during operation of the shredding head.
