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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

Agricultural machinery — Safety —
Part 17:
Root crop harvesters
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 the following types of root crop harvesting

machines trailed, mounted or self-propelled:
— sieving harvesters,
— root lifting harvesters,
— top lifting harvesters,

which carry out more than one of the following operations: haulm/leaf topping, digging/taking-in/

lifting, cleaning, conveying and unloading of root crops.
This standard is also applicable for haulm/leaf toppers used individually.

This standard is not applicable to cleaner-loaders which operate from a heap of beet, as on these type of

machines additional hazards are present not dealt with in this standard.

In addition, it specifies the type of information on safe working practices to be provided by the

manufacturer.

The list of significant hazards dealt with in this standard is given in Annex A. Annex A also indicates the

hazards which have not been dealt with.
Environmental aspects have not been considered in this standard.

This standard applies primarily to machines which are manufactured after the date of issue of the

standard.

4.2.2 The lowering of the bunker shall be controllable from the driver's station and the control shall be

of hold-to-run-type.

4.2.3 On machines with a sorting platform, emergency stop equipment complying with ISO 13850

shall be accessible from each workplace to stop the conveyor of the sorting platform. The accessibility

shall be determined according to EN 547-3+A1.

The controls for the adjustment of moving parts shall be located so that they can be operated from the

driver's station and/or the sorting platform and with the guards in guarding position. The operator's

manual shall include an appropriate notice on the need to adjust the driving speed and/or the speed of

provided. If this is not possible by direct view, mirrors or any other equivalent means shall be provided.

4.4 Haulm/leaf topping device
4.4.1 Protection against unintentional contact with the rotating tools
4.4.1.1 General

Machines shall be designed or guarded in such a way that any unintentional contact with the rotating

tools at the front, at the rear, at the sides and on the top is avoided.
4.4.1.2 Protection on the top, at the front and the rear

4.4.1.2.1 On the top, the protection shall be achieved by an imperforate guard. The front and rear edge

of these imperforate guards shall be located at a maximum height of 400 mm from the lowest point of the

tools path and at a minimum horizontal distance of 200 mm from the tools path (see Figure 1a).

4.4.1.2.2 The protection at the front and the rear shall be achieved by the extension of upper

imperforate guard to the front and to the rear (see Figure 1a).

4.4.1.3 Protection at the sides
4.4.1.3.1 In the accessible zone the lateral protection shall be:

— an imperforate guard, located near the tools and in such a way that its lower edge extends by a

minimum of 3 mm below the tools path (see Figure 1b); or

— in case the lower edge of the imperforate guard does not extend by a minimum of 3 mm below the

tools path, the lower edge of this imperforate guard shall be located at a maximum height of 400 mm

from the lowest point of the tools path and additionally by a barrier located at a maximum height of

400 mm from the lowest point of the tools path and at a minimum horizontal distance of 200 mm

from the tools path (see Figure 1c). If the height of the barrier is more than 400 mm from the lowest

point of the tools path the barrier shall be located along a contour with angle of 45 to the exterior

whereby the maximum height of the barrier shall not exceed 800 mm. Barriers at the sides can be

foldable for transport. They shall remain attached to the machine and shall be kept fixed in their

position. The operation of the tools shall be avoided when the barrier is not in protective position

(e.g. by restriction of the function of the machine components in this situation); or

— a combination of these two previous protective devices.

4.4.1.3.2 The projection on a horizontal plane of these protective devices shall be continuous.

device by a minimum of 150 mm (see Figure 2). When a conveyor belt is used, the lower edge of

the top guard shall be placed at 200 mm maximum above the upper plane of the conveyor belt (see

Figure 3);
b) at the outer point of the haulm/leaf conveying device:

— when an auger is used, a fixed guard, the lower end of which shall extend at least 50 mm below the

axis of the screw (see Figure 2);

— when a conveyor belt is used, a barrier located in the horizontal plane at 150 mm minimum from

any mobile part of the conveyor and in the vertical plane at 200 mm maximum above the upper

plane of the conveyor belt (see Figure 4).

The lateral part of the conveying belt itself shall be guarded against unintentional contact.
