1 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.
NOTE 1
ISO 14982
specifies test methods and acceptance criteria for evaluating the electromagnetic
compatibility of all kinds of mobile agricultural machinery.
NOTE 2 Specific requirements related to road traffic regulations (e.g. lighting, dimensions,
speed limit plate) are not taken into account in this part of ISO 4254.
This part of ISO 4254 is not applicable to rotary tedders and rakes which are manufactured before the date of publication of this document by ISO.
