This document specifies safety requirements and their verification for the design and construction of power take-off (PTO) drive shafts and their guards linking a tractor or self-propelled machinery to the first fixed bearing of recipient machinery. It describes methods for the elimination or reduction of risks which need specific requirements including such risks arising from misuse, reasonably foreseeable by the manufacturer. It is applicable only to those PTO drive shafts and guards mechanically linked to the shaft by at least two bearings.In addition, it specifies the type of information on safe working practices to be provided by the manufacturer.This document does not deal with:- the guards totally covering, but not mechanically linked to, the PTO drive shaft;- the mechanical characteristics of PTO drive shafts, overrun devices and torque limiters;- general hazards which are dealt with in EN ISO 4254-1:2015 (see introduction).Environmental aspects have not been considered in this document.This document is not applicable to PTO drive shafts and their guards which are manufactured before the date of publication of this document by CEN.

This document, used together with EN ISO 4254-1, 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 or materials used for animal bedding such as straw, 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.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;- cutting hazard during service on sharp parts (e.g. blades of the mixing and/or chopping device).It is not applicable to environmental hazards (except noise).It does not deal with stability when travelling.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.
