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.
