The CEN Secretary-General has advised the ISO Secretary-General that this ISO/DIS covers a subject
of interest to European standardization. In accordance with the ISO-lead mode of collaboration as
defined in the Vienna Agreement, consultation on this ISO/DIS has the same effect for CEN
members as would a CEN enquiry on a draft European Standard. Should this draft be accepted, a
final draft, established on the basis of comments received, will be submitted to a parallel two-month FDIS
vote in ISO and formal vote in CEN.
In accordance with the provisions of Council Resolution 15/1993 this document is circulated in
the English language only.
Conformément aux dispositions de la Résolution du Conseil 15/1993, ce document est distribué
en version anglaise seulement.
To expedite distribution, this document is circulated as received from the committee secretariat.
ISO Central Secretariat work of editing and text composition will be undertaken at publication
stage.
Pour accélérer la distribution, le présent document est distribué tel qu'il est parvenu du
secrétariat du comité. Le travail de rédaction et de composition de texte sera effectué au
Secrétariat central de l'ISO au stade de publication.
THIS DOCUMENT IS A DRAFT CIRCULATED FOR COMMENT AND APPROVAL. IT IS THEREFORE SUBJECT TO CHANGE AND MAY NOT BE
REFERRED TO AS AN INTERNATIONAL STANDARD UNTIL PUBLISHED AS SUCH.
IN ADDITION TO THEIR EVALUATION AS BEING ACCEPTABLE FOR INDUSTRIAL, TECHNOLOGICAL, COMMERCIAL AND USER PURPOSES, DRAFT

ISO/DIS 4254-5
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 4254-5 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 3, Safety and comfort for the operator.
This second edition cancels and replaces the first edition (1992), which has been technically revised.
ISO 4254 consists of the following parts, under the general title Agricultural machinery — Safety:
 Part 1: General requirements
 Part 3: Tractors
 Part 6: Sprayers and fertiliser distributors
 Part 7: Combine harvesters, forage and cotton harvesters
 Part 9: Equipment for sowing planting and distributing fertilisers
 Part X: Rotary rakes and tedders
Part 3 will be revised and published under separate number.
Part 4, Forestry winches, is to be revised and published as ISO 19472 (Machinery for forestry – Winches –
Terms and definitions, performance and safety).

ISO/DIS 4254-5
Introduction
The structure of safety standards in the field of machinery is as follows:
a) Type-A standards (basis safety standards) give basic concepts, principle for design, and general aspects
that can be applied to machinery;
b) Type-B standards (generic safety standards) dealing with one safety aspect(s) or one or more type(s) of
safeguards that can be used across a wide range of machinery:
 type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
 type-B2 standards on safeguards (e.g. two-hands controls, interlocking devices, pressure sensitive
devices, guards);
c) Type-C standards (machinery safety standards) dealing with detailed safety requirements for a particular
machine or group of machines.
This part of ISO 4254 is a type C standard as stated in ISO 12100-1.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards for machines
that have been designed and built according to the provisions of this type C standard.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this part of ISO 4254. These hazards are specific to power-driven soil working
equipment.
Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted
and trailed) are dealt with in ISO 4254-1:2005

DRAFT INTERNATIONAL STANDARD ISO/DIS 4254-5
Agricultural machinery — Safety —
Part 5:
Power-driven soil-working equipment
1 Scope
This part of ISO 4254, to be used together with ISO 4254-1:2005, specifies the safety requirements and their
verification for the design and construction of the different types of power-driven soil working equipment used
in agriculture. In addition, it specifies the type of information on safe working practices (including residual
risks) to be provided by the manufacturer.
This part of ISO 4254 deals with significant hazards (as listed in Annex A), hazardous situations and events
relevant to power-driven soil working equipment used as intended and under the conditions foreseen by the
manufacturer (see Clause 4).
This part of ISO 4254 is not applicable to:
 Spading machines;
 Pedestrian controlled soil working machines;
 Machines where the tools are driven by movement of the machine over the ground;
 Machines fitted with a retractable device, making them capable of working between two successive plants
in the same row.
This part of ISO 4254 is not applicable to environmental hazards, road safety, e.g. braking, lighting, etc. or
electromagnetic compatibility. It is not applicable to hazards related to maintenance or repairs carried out by
professional service personnel.
This part of ISO 4254 is not applicable to power-driven soil working equipment which is manufactured before
the date of its publication.
When requirements of this part of ISO 4254 are different from those which are stated in ISO 4254-1:2005, the
requirements of this standard take precedence over the requirements of ISO 4254-1:2005 for machines that
have been designed and built according to the provisions of this standard.
NOTE Vibrations are not regarded as significant hazard in case of mounted, semi-mounted or trailed machines.
