In addition, machinery shall comply as appropriate with EN 292 for hazards which are not covered by this standard. 1 Scope This European Standard specifies safety requirements and their verification for the design and construction of powered rotary and cylinder lawnmowers, including pedestrian-controlled and ride-on (riding) types, and lawn and garden tractors, professional lawnmowers, and lawn and garden tractors with mowing attachments. This European Standard is not applicable to machines covered by EN 786, lawn edgers, flail mowers, scrub cutters, automatic (robot) mowers, sickle-bar mowers or agricultural mowers. This standard is not applicable to rotary lawnmowers for which the cutting means is a generally circular central drive unit on which is mounted, either one or more non-metallic filaments or one or more non-metallic, pivotally mounted cutting elements. These cutting elements rely on centrifugal force to achieve cutting, with the kinetic energy of a single cutting element not exceeding 10 J. It describes methods for the elimination or reduction of hazards arising from their use; in addition, it specifies the type of information to be provided by the manufacturer on safe working practices. This standard is not applicable to lawnmowers as covered by EN 60335-2-77 and EN 50338. The list of significant hazards dealt with in this standard is given in Annex A. Annex A also indicates the hazards which have not been dealt with. Environmental aspects and EMC have not been dealt with in this standard. This European Standard applies primarily to machines which are manufactured after the date of issue of this standard. NOTE The reduction of risks from noise and vibration will be the subject of amendments to this standard now being developed. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
