1、 ANSI/ASABE AD4254-13:2012 OCT2013 Agricultural machinery Safety Part 13: Large rotary mowers American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members worldwide, who are dedicated to advancement of engineering applicable to agricultural
2、, food, and biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally agricultural field equipment, farmstead equipment, structures, soi
3、l and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Practices, and Data are informational and advisory only. Their use by a
4、nyone engaged in industry or trade is entirely voluntary. The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance with applicable ordinances, laws and regulations. Prospective users are
5、 responsible for protecting themselves against liability for infringement of patents. ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“, regardless of the revision approval date. Newly developed Standards, En
6、gineering Practices and Data approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard requires verification by ANSI that the requirements for due proces
7、s, consensus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majori
8、ty, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Additionally, procedures of ASABE require that action be t
9、aken periodically to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

ASAE S474 was used as the basis document for ISO 4254-13, Agricultural machinery Safe
14、ty Part 13: Large rotary mowers. ASAE S474.1 replaced by an adoption with deviations of ISO 4254-13:2012 October 2013; adoption approved by ANSI October 2013. Keywords: Definitions, Guarding, Mower, Rotary, Safety 0 Foreword 0.1 ANSI/ASABE AD4254-13:2012, Agricultural machinery Safety Part 13: Large
15、 rotary mowers, is an adoption with deviations of the identically titled ISO standard ISO 4254-13:2012, Agricultural machinery Safety Part 13: Large rotary mowers. Deviations noted in the following Foreword sections pertain to those provisions where harmonization could not be achieved between ASABE
16、and the International Standard. 0.2 This part of ISO 4254, when used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of towed, semi-mounted, or mounted large rotary mowers with single or multiple cutting elements which have a cutting
17、 diameter of 1 000 mm or greater for any single cutting element assembly, mounted on a propelling tractor or machine, intended for agricultural mowing equipment and designed for shredding crop residue, grass and small brush by impact. It describes methods for the elimination or reduction of hazards
18、arising from the intended use and reasonable foreseeable misuse of these machines by one person (the operator) in the course of normal operation and service. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. NOTE 1 These machines can be u
19、sed for shredding grass. When used outside agriculture, additional requirements not specified in this part of ISO 4254 can be applicable. This part of ISO 4254 is not applicable to: rotary disc mowers, rotary drum mowers, and flail mowers designed for forage crop harvesting as covered by ISO 4254-12
20、; arm-type large rotary mowers. pedestrian-controlled motor mowers; ANSI/ASABE AD4254-13:2012 OCT2013 Copyright American Society of Agricultural and Biological Engineers 2 lawn mowers covered by ISO 5395. When requirements of this part of ISO 4254 are different from those which are stated in ISO 425
21、4-1, the requirements of this part of ISO 4254 take precedence over the provisions of ISO 4254-1 for machines that have been designed and built according to the provisions of this part of ISO 4254. This part of ISO 4254, taken together with ISO 4254-1, deals with all the significant hazards, hazardo
22、us situations and events relevant to large rotary mowers used as intended and under the conditions foreseen by the manufacturer. (A list of significant hazards is provided in Annex A.) NOTE 2 Example illustrations of two mowers (a rigid-deck large rotary mower and a trail-type multi-section foldable
