IEC 62841-4-3:2020

IEC 62841-4-3:2020 This document applies to the design of pedestrian controlled walk-behind - cylinder lawnmowers; and - rotary lawnmowers equipped with - metallic cutting means; and/or - rigid non-metallic cutting means; and/or - non-metallic cutting means with one or more cutting elements pivotally mounted on a generally circular drive unit, where these cutting elements rely on centrifugal force to achieve cutting, and have a kinetic energy for each single cutting element of greater than 10 J. This document does not apply to - robotic lawnmowers; - remote-controlled lawnmowers; - flail mowers or flail-type attachments; - scissors type lawnmowers; - grassland mowers; - sickle bar mowers; - towed/semi-mounted grass-cutting machines; - scrub-clearing machines; - lawn trimmers and lawn edge trimmers; - lawn edgers; - grass trimmers; - brush cutters; - brush saws; - agricultural mowers; - trailing seat/sulky units; - ride-on machines; - non-powered lawnmowers; - combustion engine powered lawnmowers; - hybrid and fuel cell powered machines and associated charging systems; and - garden tractors or their attachments. Robotic lawnmowers are covered by IEC 60335-2-107, and will be covered by a future part of IEC 62841.
