A horticultural or agricultural cutting device is disclosed which comprises a body (4), a rotor (20) rotatably coupled to the body, at least one cutter (54), (56) which rotates along with the rotor and extends radially to the axis of rotation, and a powered drive (eg. an electric motor (40)) which drives the rotor and cutter. The rotor provides a collection surface (58). (60) which follows the cutter as it rotates and so serves to collect cut material. The rotor is formed such as to expel the cut material centrifugally and the body provides a roughly tangential collection channel away from the rotor along which the collected material is thereby propelled. The collection channel is led to a waste receptacle.
