ASAE/ASABE AD4254-13:2012 OCT2013 (R2023)

ANSI/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.

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 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.
