This clause of Part 1 is applicable, except as follows:
Addition:
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.
NOTE 101 Machines that have non-metallic cutting means and a kinetic energy for each single cutting element of less than or equal to 10 J are considered to be lawn trimmers.
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, including those that can be operated in pedestrian controlled mode;
– non-powered lawnmowers;
– combustion engine powered lawnmowers;
– hybrid and fuel cell powered machines and associated charging systems; and
– garden tractors or their attachments.
NOTE 102 Robotic lawnmowers are covered by IEC 60335-2-107, and will be covered by a future part of IEC 62841.
