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 4254-10 was prepared by the European Committee for Standardization (CEN) Technical Committee

CEN/TC 144, in collaboration with ISO Technical Committee TC 23, Tractors and machinery for agriculture

and forestry, Subcommittee SC 7, Equipment for harvesting and conservation, in accordance with the

Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Introduction
The structure of safety standards in the field of machinery is as follows:

a) type-A standards (basic standards) giving basic concepts, principles for design, and general aspects that

can be applied to machinery;

b) type-B standards (generic safety standards) dealing with one safety aspect or one type 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-hand control devices, 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 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 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 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 rotary tedders and rakes.

Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted

and trailed) are dealt with in ISO 4254-1.

1 Scope

This part of ISO 4254, to be used together with ISO 4254-1, specifies the safety requirements and their

verification for the design and construction of rotary tedders, rotary rakes and rotary tedder–rakes, including

rotary drum rakes, used by one person (the operator) only, having one or several powered rotors, mounted,

semi-mounted, trailed or self-propelled. 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 is not applicable to:

a) machines with ground-driven tines or ground-wheel–driven tines (e.g. sunflower rakes);

b) parallel bar rakes;
c) chain or endless belt type rakes;
d) pedestrian-controlled tedders and rakes;
e) machines equipped with a pick-up device.

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 for machines that

have been designed and built according to the provisions of this part of ISO 4254.

This part of ISO 4254, taken together with ISO 4254-1, deals with all the significant hazards, hazardous

situations and events relevant to rotary tedders, rotary rakes and rotary tedder–rakes when they are used as

intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see

Clause 4), excepting the hazards arising from:
⎯ the environment, other than noise;
⎯ electromagnetic compatibility;
⎯ vibration;

⎯ overturning in regard to the protection of the operator at the driving station of a self-propelled machine;

⎯ moving parts for power transmission except strength requirements for guards and barriers;

⎯ safety and reliability of control systems.

NOTE 1 ISO 14982 specifies test methods and acceptance criteria for evaluating the electromagnetic compatibility of

all kinds of mobile agricultural machinery.

NOTE 2 Specific requirements related to road traffic regulations (e.g. lighting, dimensions, speed limit plate) are not

taken into account in this part of ISO 4254.
