Preface 

This is the harmonized CSA Group and ULSE standard for Electric Motor-Operated Hand-Held Tools, Transportable Tools and Lawn and Garden Machinery – Safety – Part 4-3: Particular Requirements for Pedestrian Controlled Walk-Behind Lawnmowers . It is the First edition of CSA C22.2 No. 62841-4-3 and the First edition of UL 62841-4-3. This harmonized standard is based on IEC Publication 62841-4-3: First edition, Electric Motor-Operated Hand-Held Tools, Transportable Tools and Lawn and Garden Machinery – Safety – Part 4-3: Particular Requirements for Pedestrian Controlled Walk-Behind Lawnmowers, issued November 2020. IEC publication 62841-4-3 is copyrighted by the IEC. This harmonized standard was prepared by CSA Group and ULSE. The efforts and support of the International Harmonization Committee (IHC) for the adoption of the IEC series of standards for Hand-Held, Motor-Operated, and Transportable Tools and Lawn and Garden Machinery are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. This standard was reviewed by the CSA Subcommittee on Safety of Hand-Held Motor-Operated Electric Tools, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 

Scope 

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; 

– 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. 

NOTE 103 Lawn trimmers and lawn edge trimmers are covered by IEC 60335-2-91. 

NOTE 104 Lawn trimmers, lawn edge trimmers, grass trimmers, brush cutters and brush saws will be covered by a future part of IEC 62841. 

NOTE 105 Lawn edgers will be covered by a future part of IEC 62841.
