ABSTRACT:
This invention provides garden refuse shredding apparatus (10) which has a chipping rotor (20) supported for rotation about a vertical shaft (31) in a chamber (11) which has a hopper (14) which feeds refuse to radially disposed elongate chipper blades (30) which span a major part of the rotor (28). Fan blades (44) are supported on the rotor for creating an airflow through the hopper (14) to assist feed to the chipping rotor and to assist discharge of shredded refuse from the outlet (45). The chipping rotor (20) is driven directly from the vertical output shaft (36) of an electric motor or a petrol engine (21).
