EN 13448:2001+A1:2009 (E) 4 Introduction This document is a type C standard as stated in EN 1070. The machinery concerned and the extent to which hazards are covered is indicated in the scope of this standard. These hazards are specific to inter-row mowing units. The hazards that are common to all agriculture machines (self-propelled, mounted, semi-mounted and trailed) are dealt with in EN 1553:1999. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. 1 Scope This European Standard specifies the safety requirements and test methods for the design and construction of inter-row mowing units with vertical spindles mounted on grass cutting machines such as flail mowers, used in agriculture, forestry and landscaping to cut the grass in the area between two successive obstruction. It describes methods for elimination or reduction of risks arising from their use. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. This standard is not applicable to rotary mowers and flail-mowers which are covered by EN 745. Environmental aspects have not been considered in this standard. This European Standard is not applicable to inter-row mowing units which are manufactured before the date of publication of this document by CEN. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

Immediately after the obstacle has been passed, the sensor returns to its original position, and the boom returns to the working position. 3.4 target device which registers the number of impacts of objects propelled by the mowing unit 3.5 danger zone area surrounding the machine with a radius of 50 m as measured from the centre of the unit

EN 13448:2001+A1:2009 (E) 6 4 List of hazards The hazards, among those which appear in EN 292-1 and EN 292-2 and are considered applicable to machines covered by the standard are listed in annex A. Annex A also indicates the hazards which have not been dealt with. 5 Safety requirements and/or measures 5.1 General Machinery shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of EN 292 for hazards which are not dealt with by this standard and especially with annex A of EN 292-2:1991/A1:1995 when EN 292 does not give precise requirements. Unless otherwise specified in this standard, the machine shall comply with the requirements of EN 1553:1999 and EN 745 and with Tables 1, 3, 4 and 6 of EN 294:1992. 5.2 Protection of cutting elements The machine shall be equipped with an imperforate blade enclosure which fully covers the cutting elements, capable of ensuring a safety distance of at least 50 mm beyond the external trajectory of the cutting elements and which extend at least 3 mm below the plane of the blade tip circle (see Figure 2). The blade enclosure shall be free of protrusions and sharp edges and, in the case of a mechanical pivoting boom, the device which allows the unit to rotate idly when it encounters an obstruction shall be designed, so that the rotary movement of the cutting elements is not imparted to the blade enclosure itself. The blade enclosure and the parts of the machine ensuring the guarding shall withstand a vertical downwards load of 1200 N, and, in order to resist to the forces generated when the blade enclosure hits an obstruction, shall additionally withstand the following horizontal loads:  600 N for machines intended to be used with a tractor whose maximum power as given in the instruction handbook is less or equal to 37 kW;  1 000 N for the other machines. These requirements shall be checked by the test procedure and the test acceptance defined in EN 1553:1999, annex B.

Key 1 Ground 2 Blade tip circle 3 Blade enclosure Figure 2 5.3 Hose protection In the case of hydraulically or pneumatically operated inter-row mowing units, pipes and hoses shall be fitted, assembled and if necessary retained to minimise contact with hot surfaces, friction and other unintentional exterior damage. Visual inspection of hoses and fittings shall be possible except those located inside frames.
Hydraulic hoses containing fluid with a pressure of more than 5 MPa (50 bar) and/or having a temperature over 50 °C, and which are located within 1 m of the operator, shall be guarded in accordance with EN ISO 3457:1995, 4.9. Any part or component which may divert a possible jet of fluid can be considered as a sufficient protection device. 5.4 Thrown objects The possibility that objects propelled by the rapid rotary action of the cutting elements during operation, which may constitute a hazard and risk of injury to the operator, shall be prevented. Tests shall be performed in accordance with the indications given in clause 6. 5.5 Requirements for pivoting booms Requirements for the pivoting boom including its strength, mounting, control system and control devices will be added at a future revision of the standard. 5.6 Noise Noise emission from inter-row mowing units shall be measured according to EN 1553:1999, annex D. Noise will be fully dealt with at a future revision of the standard. SIST EN 13448:2002+A1:2010
