European foreword

This document (prEN 703:2018) has been prepared by Technical Committee CEN/TC 144 “Tractors and

machinery for agriculture and forestry”, the secretariat of which is held by AFNOR.

This document is currently submitted to the CEN Enquiry.
This document will supersede EN 703:2004+A1:2009.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

document.

EN 703:2004+A1:2009 has been technically revised. The main following changes were introduced:

— update the normative references;
— clarification of the scope (excludes silage buckets);

— improvement of the safety requirements in particular regarding controls, visibility, protection

against cutting tools, blockages, loading door, inspection of mixing, access (addition of feedstuffs),

conveyors, access to turbines;

— addition of new clauses on: jacking points, brakes, stability and immobilisation, remote control,

electro-magnetic compatibility (EMC), completion of instructions, safety signs.

Introduction
This document is a type-C standard as specified in EN ISO 12100.

The machinery concerned and the extent to which hazards, hazardous situations and hazardous events

are covered are indicated in the scope of this document. These hazards are specific to silage loading,

mixing and/or chopping and distributing machines.

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

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

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.

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 organizations, 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.

This document does not apply to:
— machines which pick up green fodder directly from the field;
— loading cranes;
— silage buckets.
NOTE 1 Loading cranes are dealt with in EN 12999.

NOTE 2 Autonomous silage loading, mixing and/or chopping and distributing machines (robotic feed systems)

are to be dealt with in a separate standard (under preparation).

This document deals with the significant hazards, hazardous situations and events relevant to machines

for loading, mixing and/or chopping and distributing silage and/or other feedstuffs, when they are used

as intended and under the conditions foreseen by the manufacturer as listed in Clause 4, except for the

hazards arising from:
— failure of the control circuit;
— inadequate seating;
— inadequate lighting;
— travelling of machinery;
— break-up of parts rotating at high speed;

5 Safety requirements and/or protective measures
5.1 General

Machinery shall comply with the safety requirements and/or protective measures of this clause. In

addition, the machine shall be designed according to the principles of relevant parts of EN ISO 12100

for hazards relevant but not significant, which are not dealt with by this document (e.g. burns and

scalds).

Unless otherwise specified in this standard, the machines shall comply with the requirements of

EN ISO 4254-1:2015 and with EN ISO 13857:2008, Table 1, Table 3, Table 4 and Table 6 as appropriate.

5.2 Location of the manual controls
5.2.1 General

It shall not be possible for the operator, when inside the mixing and/or chopping compartment(s), to

reach the manual controls.

The control system shall be such that it is not possible for the operator to reach unguarded mobile

working tools while actuating the control. This requirement is considered met for mounted machines

when the distance between the manual controls and any unguarded mobile working tools in operation

is more than 850 mm.

For mounted, semi-mounted or trailed machines, when controls require actuation from the driver's

station, these controls shall be designed so that the operator can reach them, for example by means of

an adjustable position of the controls or controls that can be situated inside the tractor.

Verification: shall be by measurement and inspection.

Where there is more than one control position, the control system shall be designed in such a way that

the use of one of them precludes the use of the others, except for stop controls and
