scope:

This part of ISO 4254, to be used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of rotary tedders, rotary rakes and rotary tedder-rakes, including rotary drum rakes, used by one person (the operator) only, having one or several powered rotors, mounted, semi-mounted, trailed or self-propelled. In addition, it specifies the type of information on safe working practices, including residual risks, to be provided by the manufacturer. This part of ISO 4254 is not applicable to: a) machines with ground-driven tines or ground-wheel-driven tines (e.g. sunflower rakes); b) parallel bar rakes; c) chain or endless belt type rakes; d) pedestrian-controlled tedders and rakes; e) machines equipped with a pick-up device. When requirements of this part of ISO 4254 are different from those which are stated in ISO 4254-1, the requirements of this part of ISO 4254 take precedence over the requirements of ISO 4254-1 for machines that have been designed and built according to the provisions of this part of ISO 4254. This part of ISO 4254, taken together with ISO 4254-1, deals with all the significant hazards, hazardous situations and events relevant to rotary tedders, rotary rakes and rotary tedder-rakes when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4), excepting the hazards arising from: - the environment, other than noise; - electromagnetic compatibility; - vibration; - overturning in regard to the protection of the operator at the driving station of a self-propelled machine; - moving parts for power transmission except strength requirements for guards and barriers; - safety and reliability of control systems.
