This European Standard specifies safety requirements and their verification for design and construction of pedestrian controlled motor mowers with rotary or reciprocating cutting means used in agricultural, forestry and landscaping to cut and/or mulch grass or similar plants or scrub and woody vegetation. For the purposes of this standard the following types of pedestrian controlled machines are considered to be motor mowers: – flail mowers; – grassland mowers; – scrub clearing machines; – sickle bar mowers. This standard applies also to multipurpose machines when used for cutting or mulching grass or scrub. Note When they are used for other operations (e.g. soil working) other standards can apply. This standard does not cover lawn mowers (see EN ISO 5395 1, EN ISO 5395 2), engine driven brush cutters and grass trimmers (see EN ISO 11806) or other lawn maintenance equipment. This document deals with significant hazards, hazardous situations and events, as listed in Annex A, relevant to pedestrian controlled motor mowers when used as intended and under conditions of misuse foreseeable by the manufacturer during normal operation and service. Additionally, it specifies the type of information to be provided by the manufacturer on safe working practices. Environmental aspects (except noise) have not been considered in this standard. This document is not applicable to motor mowers manufactured before the date of its publication.
