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 4254-1 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 3, Safety and comfort of the operator.
This third edition cancels and replaces the second edition (ISO 4254-1:1989), which has been technically
revised. It also incorporates the Amendment ISO 4254-1:1989/Amd.1:1998.
ISO 4254 consists of the following parts, under the general title Agricultural machinery — Safety:
 Part 1: General requirements
 Part 2: Anhydrous ammonia applicators
 Part 3: Tractors
 Part 5: Power-driven soil-working equipment
 Part 6: Equipment for crop protection
 Part 7: Combine harvesters, forage and cotton harvesters
 Part 9: Equipment for sowing, planting and distributing fertilizers
Part 4, Forestry winches, is to be revised and published as ISO 19472, and part 6 is to be revised and
published under the title Sprayers and liquid fertilizer distributors.

ISO 4254-1:2005(E)
Introduction
The structure of safety standards in the field of machinery is as follows.
a) Type-A standards (basis 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 or more 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 type-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 self-propelled ride-on, trailed,
semi-mounted and mounted agricultural machines.

INTERNATIONAL STANDARD ISO 4254-1:2005(E)

Agricultural machinery — Safety —
Part 1:
General requirements
1 Scope
This part of ISO 4254 specifies the general safety requirements and their verification for the design and
construction of self-propelled ride-on machines and mounted, semi-mounted or trailed 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.
This part of ISO 4254 deals with significant hazards (as listed in Annex A), hazardous situations and events
relevant to this agricultural machinery used as intended and under the conditions foreseen by the
manufacturer (see Clause 4). For compliance with European Directives, Annex C is additionally applicable.
This part of ISO 4254 is not applicable to
 tractors,
 aircraft,
 air-cushion vehicles, or
 lawn and garden equipment.
This part of ISO 4254 is not applicable to environmental hazards, road safety, electromagnetic compatibility,
vibration or power take-off (PTO) and PTO drive shaft guarding between self-propelled machines/tractors and
the first bearing of recipient machinery. It is not applicable to hazards related to maintenance or repairs to be
carried out by professional service personnel.
NOTE ISO 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 machines which are manufactured before the date of its publication.
All of the hazards dealt with by this part of ISO 4254 will not necessarily be present on a particular machine.
For any machine covered by this part of ISO 4254, the provisions of the part of ISO 4254 directly applicable to
that type of machine, if available, take precedence over the provisions of this part of ISO 4254.

4 Safety requirements and/or measures applicable to all machines
4.1 Fundamental principles, design guidance
4.1.1 The machine shall be designed according to the principles of risk reduction specified in
ISO 12100-1:2003, Clause 5, for hazards relevant but not significant.
4.1.2 Unless otherwise specified in this part of ISO 4254, safety distances shall comply with the
requirements given in ISO 13852:1996, Tables 1, 3, 4 or 6.
4.1.3 Functional components which need to be exposed for proper function, drainage or cleaning shall be
guarded without causing other hazards, for example risk of fire due to the accumulation of organic material
during the intended operation or use.
4.2 Noise
4.2.1 The technical information given in ISO/TR 11688-1 shall be used as means to design low-noise
machinery.
NOTE 1 ISO/TR 11688-2 also gives useful information on noise-generation mechanisms in machinery.
NOTE 2 Noise generation may vary considerably between machinery types. Noise reduction measures are therefore
dealt with in product specific standards.
