5、 This standard has been prepared by Technical Committee CEN/TC 144 “Tractors and machinery for agriculture and forestry” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Section La
6、ndtechnik. Amendment of the European Machinery Directive has made it necessary to review the previously valid standard, EN 12733:2001, in terms of the essential requirements of the new European Machinery Directive, 2006/42/EC. This standard contains specifications meeting the essential requirements
7、set out in Annex I of the “Machinery Directive”, Directive 98/37/EC (valid until 28 December 2009), and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to pedestrian controlled motor mowers that are either first placed on the market or
8、 commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may
9、assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in this document have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standards which have not been publ
10、ished as DIN ISO Standards with the same number, there are no national standards available. Amendments This standard differs from DIN EN 12733:2001-09 as follows: a) Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 98/37/EC” has been
11、updated; b) Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC” has been included. Compared with DIN EN 12733:2009-07 the following correction has been made to the German version only, the English text is therefore not affect
12、ed: a) in Annex I, Subclause I.3, first paragraph, it shall read “(150 5) mm” (instead of “ca. 150 mm”).

DIN EN 12733:2011-06 EN 12733:2001+A1:2009 (E) 4 Introduction The extent to which hazards are covered is indicated in the scope of this standard. 1 Scope This standard specifies safety requirements and their verification for
36、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. For the purposes of this standard the following types of pedestrian cont
37、rolled 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 scrub. This standard does not cover lawn mowers (see EN 836), engine drive
38、n 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 specifies the type of information to be provided by the manufacturer on safe w
39、orking 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 Standard incorporates by dated or undated reference, provisions from oth
40、er publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or
