Introduction
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organisations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e. g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
This document is a type-C standard as stated in ISO 12100.
When requirements of this type-C standard are different from those which are stated in type-A or
type-B standards, the requirements of this type-C standard take precedence over the requirements of
the other standards for machines that have been designed and built according to the requirements of
this type-C standard.
The structure of safety standards in the field of machinery is as follows.
— Type-A standards (basis standards) give basic concepts, principles for design, and general aspects
that can be applied to machinery.
— Type-B standards (generic safety standards) deal with one or more safety aspects or one or more
types 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).
— Type-C standards (machinery safety standards) deal with detailed safety requirements for a
particular machine or group of machines.
Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-
mounted and trailed) are dealt with in ISO 4254-1.

Introduction
The structure of safety standards in the field of machinery is as follows.
Type-A standards (basis standards) give basic concepts, principles for design, and general aspects that
can be applied to machinery.
Type-B standards (generic safety standards) deal 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);
Type-C standards (machinery safety standards) deal 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.
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 power-driven soil-working
machines.
Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted
and trailed) are dealt with in ISO 4254-1.

DRAFT INTERNATIONAL STANDARD ISO/DIS 4254-5
Agricultural machinery — Safety — Part 5: Power-driven soil-
working equipment
1 Scope
This part of ISO 4254, 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.
This part of ISO 4254 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 foreseen by the
manufacturer (see Clause 4).
This part of ISO 4254 is not applicable to:
spading machines;
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 or electromagnetic compatibility. It is not
applicable to hazards related to moving parts for power transmission, except for strength requirements for
guards and barriers, nor 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 part of ISO 4254.
NOTE 2 Vibrations are not regarded as a significant hazard in the case of mounted, semi-mounted or trailed machines.
This part of ISO 4254 is not applicable to power-driven soil-working machines which are 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, the
requirements of this part of ISO 4254 take precedence over the requirements of ISO 4254-1.

ISO/DIS 4254-5
3.1
power-driven soil-working machine
machine with powered driven cutting, chopping, or stirring components which rotate or oscillate designed for
modifying soil structure or profile, for incorporating plant and crop residues or animal manure during tillage, or
for both functions
NOTE See Annex B for examples of such machines.
3.2
attachment
equipment which can be fitted to a power-driven soil-working machine and which allows the function of the
machine to be modified
3.2.1
attachment preventing access
attachment which restricts access onto the top of the power-driven soil-working machine and its driven tools at
the rear
EXAMPLE Seed drills.
3.2.2
attachment not preventing access
equipment which allows access onto the top of the power-driven soil-working machine
EXAMPLE Frames, rollers or harrows.
4 Safety requirements and measures
4.1 General
Machinery shall comply with the safety requirements and protective measures of this clause. Unless otherwise
specified in this part of ISO 4254, the machine shall comply with the requirements of ISO 4254-1.
The compliance with the safety requirements and measures shall be verified in accordance with Clause 5.
4.2 Noise reduction at the design stage
The main noise sources when operating power-driven mounted, semi-mounted and trailed soil-working
machines are the tractor, the engagement of tools with the soil — neither of which is under the control of the
machine manufacturer — and the gearbox of the machine. Appropriately designed gearwheels, drives and oil
bath lubrication and cooling can be seen as measures for noise reduction at the design stage.
4.3 Protection against inadvertent contact with power-driven tools and against thrown
objects
4.3.1 Machines shall be designed or guarded in accordance with 4.3.1.1 to 4.3.1.5 in order to avoid
inadvertent contact with the powered tools at the front, rear, sides and top of the machine during normal
operation and service.
4.3.1.1 At the front, sides and rear of the accessible zone shown in Figure 1, a barrier shall extend from
the outermost path of the tools to a distance, a, beyond the path of the tools as shown in Figure 2 a) and b).
4.3.1.2 On the top of the machine, the area between the barriers shall be guarded as follows.
a) The area covering the tools up to the outermost points of their path shall be guarded by a solid guard.

b) The area between the barriers and the edge of the top guard shall be covered in such a way that it is not
possible to gain access to the tools. This guarding may be achieved by a guard, any suitable part of the
machine or a combination of both.
4.3.1.3 On the sides and rear of the machine, when in the working position, for the guard covering the
parts of the tools above the ground, distance a may extend to less than 200 mm (see Figure 3).This guard
shall not be perforated.
