0 Introduction
This document is a type C standard as stated in EN 1070.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document. These hazards are specific to machines for loading (including silage
cutting), mixing and/or chopping and distributing silage.
Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted and
trailed) are dealt with in EN 1553.
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.
1 Scope
This document, used together with EN 1553, specifies the safety requirements and their verification for the design
and construction of mounted, semi-mounted, trailed or self-propelled machines that have a combination of two or
more of the following functions: loading, mixing, chopping and distributing silage and/or other feedstuffs, to be used
by one operator only. It includes those fitted with a built-in loading crane. In addition, it specifies the type of
information on safe working practices (including residual risks) to be provided by the manufacturer.
This document applies only to machines that have the following functional combinations:
 mixing and distributing functions; or
 mixing, chopping and distributing functions; or
 loading, mixing and distributing functions; or
 loading, mixing, chopping and distributing functions; or
 chopping and distributing functions; or
 loading, chopping and distributing functions.
Silage block cutters, even if they carry out a single function, are covered by this document.
It does not apply:
 to machines which pick up green fodder directly from the field;
 to loading cranes;
 to silage buckets.
NOTE 1 Loading cranes are dealt with in EN 12999.
NOTE 2 Silage buckets will be dealt through an amendment or during next revision.
This document deals with all 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;
 impossibility of stopping the machine in the best possible conditions;
 travelling of machinery;
 break-up of parts rotating at high speed.
It is not applicable to environmental hazards (except noise).
This document is not applicable to machines for loading, mixing and/or chopping and distributing silage and/or
other feedstuffs which are manufactured before the date of publication of this document by CEN.
