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.
