No L 186/26 Official Journal of the European Communities 8.7.86 COUNCIL DIRECTIVE of 26 May 1986 on rear-mounted roll-over protection structures of narrow-track wheeled agricultural and forestry tractors (86/298/EEC) THE COUNCIL OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, and in particular Article 100 thereof, Having regard to the proposal from the Commission (1), Having regard to the the Parliament (2), opinion of European Having regard to the opinion of the Economic and Social Committee (3), Whereas Council Directive 74/150/EEC of 4 March 1974 on the approximation of the laws of the Member States relating to the type-approval of wheeled agricultural or forestry tractors (*), as last amended by the Act of Accession of Spain and Portugal, lays down that the necessary provisions for the implementation of the EEC type-approval procedure in respect of individual tractor parts or characteristics should be specified in special directives; whereas the provisions relating to roll-over protection structures and their attachments to tractors were laid down by Directives 77/536/EEC (*) and 79/622/EEC (¢), as last amended by the Act of Accession of Spain and Portugal; whereas these two Directives cover respectively dynamic and static testing procedures — either of which may be employed by manufacturers for the present — and relate to standard tractors, that is, tractors having a maximum ground clearance of 1 000 mm and a fixed or adjustable track width of one of the driving axles of not less than 1 150 mm and weighing between 1,5 and 4,5 tonnes in the case of tractors covered by the ‘dynamic testing’ Directive and not less than 800 kilograms in the case of tractors covered by the ‘static testing’ Directive; Whereas the tractors covered by this Directive have a maximum ground clearance of 600 mm, a minimum track width of both axles of less than 1 150 mm and a mass greater than 600 kilograms; whereas the roll-over protection structures of these tractors, which are used for specific activities, can be made subject to specific requirement or requirements other than those of Directive 77/536/EEC and 79/622/EEC; 1 (1) OJ No C 123, 9. 5. 1983, p. 1. (2) OJ No C 307, 14. 11. 1983, p. 103. (3) OJ No C 286, 24. 10. 1983, p. 2. (*) OJ No L 84, 28. 3. 1974, p. 10. (5) OJ No L 220, 29.8.1977, p. 1. () O] No L 179, 17.7.1979, p. 1. Whereas the technical requirements with which such ‘narrow-track’ tractors must comply pursuant to national laws relate inter alia to roll-over protection structures and to their attachment to the tractor; whereas those requirements differ from one Member State to another; whereas it is therefore necessary that all Member States adopt the same requirements either in addition to or in place of their existing rules in order, in particular, to allow the EEC type-approval procedure which was the subject of Directive 74/150/EEC to be introduced in respect of each type of tractor; Whereas this Directive covers roll-over protection structures of the rear-mounted rollbar, frame or cab type having a zone of clearance whose upper limit is 900 mm above the seat reference point in order to provide a sufficiently large area or unobstructed space for the protection of the driver; whereas another special Directive will be adopted in respect of roll-over protection structures having two pillars mounted in front of the driver; Whereas a harmonized component type-approval procedure for roll-over protection structures and their attachment to the tractor makes it possible for each Member State to check compliance with the common construction and testing requirements and to inform the other Member States of its findings by sending them copies of  the component type-approval certificate completed for each type of roll-over protection structure and its attachment to the tractor; whereas the placing of an EEC component type-approval mark on all structures manufactured in conformity with the approved type obviates any need for technical checks on those structures in the other Member States; whereas common requirements concerning other elements and characteristics of the roll-over protection structure, in particular, devices to prevent continuous roll-over if the tractor overturns, and protection of occupants, will be laid down at a later date; Whereas the harmonized requirements are intended principally to ensure safety on the road and at work throughout the Community; whereas, for this reason, it is necessary to introduce the obligation for tractors covered by this Directive to be fitted with roll-over protection structures;. Whereas the approximation of the national laws relating to these tractors entails reciprocal recognition by Member States of the checks carried out by each of them on the basis of the common requirements,
