Agricultural machinery - Safety - Part 13: Large rotary mowers
Published by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.orgASAE ANSI/ASABE AD4254-13:2012 October 2013
0.1ANSI/ASABE AD4254-13:2012, Agricultural machinery Safety Part 13: Large 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 and the International Standard.
0.2This 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 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 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 1These machines can be used 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;
arm-type large rotary mowers.
pedestrian-controlled motor mowers;
lawn mowers covered by ISO 5395.
When requirements of this part of ISO 4254 are different from those which are stated in ISO 4254-1, 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, hazardous 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 2Example illustrations of two mowers (a rigid-deck large rotary mower and a trail-type multi-section foldable-wing large rotary mower) dealt with in this part of ISO 4254 are shown in C.1.
NOTE 3Example illustrations of mowers not dealt with in this part of ISO 4254 are shown in C.2.
This part of ISO 4254 is not applicable to environmental hazards, road safety, electromagnetic compatibility, vibration and hazards related to moving parts for power transmission. It is also not applicable to hazards related to maintenance or repairs to be carried out by professional service personnel.
NOTE 4ISO 14982 specifies test methods and acceptance criteria for evaluating the electromagnetic compatibility of all kinds of mobile agricultural machinery.
This part of ISO 4254 is not applicable to large rotary mowers which are manufactured before the date of publication of this document by ISO.
0.3Ten Normative references listed in ISO 4254-13. The responsible ASABE committee has reviewed these references and approved the following deviations:
0.3.1Replace ISO 730:2009, Agricultural wheeled tractors Rear-mounted three-point linkage Categories 1N, 1, 2N, 2, 3N, 3 and 4N, 4, with ANSI/ASABE AD730:2009 DEC2012, Agricultural wheeled tractors Rear-mounted three-point linkage Categories 1N, 1, 2N, 2, 3N, 3, 4N and 4. Any reference to ISO 730:2009 in the printed portion of the ISO 4254-13:2012 text shall be replaced by ANSI/ASABE AD730:2009 DEC2012.
0.3.2Replace ISO 11684:1995, Tractors, machinery for agriculture and forestry, powered lawn and garden equipment Safety signs and hazard pictorials General principles, with ANSI/ASABE AD11684:1995 APR2011, Tractors, machinery for agricultural and forestry, powered lawn and garden equipment Safety signs and hazard pictorials General principles. Any reference to ISO 11684:1995 in the printed portion of the ISO 4254-13:2012 text shall be replaced by ANSI/ASABE AD11684:1995 APR2011.
0.3.3Add ANSI/ASABE S604, Safety for Power Take-off (PTO), Implement Input Driveline (IID), Implement Input Connection (IIC), and Auxiliary Power Take-off (aux. PTO) for Agricultural Field Equipment
0.4This standard has been approved as an American National standard by ANSI (American National Standard Institute). The original content of ISO 4254-13 was based on ASAE S474, Agricultural Rotary Mower Safety.
0.5This standard deviates from ISO 4254-13:2012 as follows:
0.5.1See Section 0.3 for Normative reference deviations.
0.5.2Add to the end of Foot-probe test procedure section 22.214.171.124: (except the highest cutting position for this test shall not exceed 200 mm).
