29、his standard specifies safety requirements and their verification for design and construction of pedestrian controlled motor mowers with rotary or reciprocating cutting blades used in agricultural, forestry and landscaping to cut and/or mulch grass or similar plants or scrub and woody vegetation. Fo
30、r 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 are used for cutting or mulching grass or scru
31、b. This standard does not cover lawn mowers (see EN 836), engine driven brush cutters and grass trimmers (see EN ISO 11806) or other lawn maintenance equipment. This standard describes methods for the elimination or reduction of hazards arising from the use of motor mowers. Additionally, it specifie
32、s the type of information to be provided by the manufacturer on safe working practices. Environmental aspects have not been considered in this standard. This standard applies primarily to machines which are manufactured after the date of issue of the standard. 2 Normative references This European St
