ISO 4254-5:2018, intended to be used together with ISO 4254‑1, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted and trailed power-driven soil-working machines used in agriculture. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer.

ISO 4254-5:2018 deals with significant hazards (as listed in Annex A), hazardous situations and events relevant to power-driven soil-working machines used as intended and under the conditions foreseeable by the manufacturer (see Clause 4).

ISO 4254-5:2018 is not applicable to

- spading machines, and

- machines fitted with a retractable device making them capable of working between two successive plants in the same row.

ISO 4254-5:2018 is not applicable to environmental hazards. It is not applicable to hazards related to moving parts for power transmission (except for strength requirements for guards and barriers) or to maintenance or repairs carried out by professional service personnel.

NOTE 1 Specific requirements related to road traffic regulations are not taken into account in this document.

NOTE 2 Vibrations are not regarded as a significant hazard in the case of mounted, semi-mounted or trailed machines.

ISO 4254-5:2018 is not applicable to power-driven soil-working machines which are manufactured before the date of its publication.

When requirements of this document are different from those which are stated in ISO 4254‑1, the requirements of this document take precedence over the requirements of ISO 4254‑1 for machines that have been designed and built according to the provisions of this document.
