Abstract

Circular saw-type plastic cutter for rotary lawn mower comprises a cutting blade made of a one-piece, perforated circular metal or plastic disc with cutting blades made of plastic, e.g. polyurethane, around its periphery. The latter cutting zone is injection-moulded or similar to the centre disc. The circular cutter has a smoother action than the boom-type cutters often used, and because of its many teeth does not get blunt so quickly.
