BRITISH STANDARD BS EN 708:1997 Incorporating Amendment No Agricultural machinery — Soil working machines with powered tools — Safety The European Standard EN 708:1996, with the incorporation of amendment A1:2000, has the status of a British Standard ICS 65.060.20 BS EN 708:1997 Committees responsible for this British Standard The preparation of this British Standard was entrusted to Technical Committee AGE/32, Agricultural implements and trailers, upon which the following bodies were represented: Agricultural and Allied Workers National Trade Group Agricultural Engineers’ Association British Fluid Power Association Department of Transport Health and Safety Executive Ministry of Agriculture, Fisheries and Food National Farmers’ Union Silsoe College, Cranfield Institute of Technology Silsoe Research Institute This British Standard, having been prepared under the direction of the Engineering Sector Board, was published under the authority of the Standards Board and

— Soil working machines with powered tools — Safety, including amendment A1:2000, published by the European Committee for Standardization (CEN) The United Kingdom as a member of CEN is obliged to publish EN 708:1996 as a British Standard However attention is drawn to the fact that during the development of this European Standard the United Kingdom has consistently voted against its approval as an EN The UK believes that the standard is deficient in certain safety requirements compared with the state of the art for these machines in the UK and that in consequence the standard fails to meet some of the essential requirements of the EC Machinery Safety Directive, 89/392 and amendments, which it claims to meet Although CEN approved EN 708:1996 for publication in its present form there is no reference to it in the Official Journal of the European Communities It should therefore be noted that until the standard is listed in the Official Journal, compliance with it will not give automatic presumption of compliance either with the relevant essential requirements of the EC Machinery Directive or the UK Supply of Machinery (Safety) Regulations 1992 as amended in 1994 As part of BSI’s duty of care we draw attention to users of BS EN 708:1997 of our concern that the standard contains inadequate requirements for protection of personnel against unintentional contact with the powered tools specifically with regard to clause 4.2.2 and the absence of a strength requirement for barriers and lateral guards BSI will assume no liability whatsoever for any failure on the part of any user of this standard to consider these aspects Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI

specific to soil working machines with powered tools The hazards that are common to all agricultural machines (self-propelled, mounted, semi-mounted and trailed) will be dealt with in a standard currently in preparation (EN 1553) Scope This standard specifies safety requirements and their verification for the design and construction of soil working machines, mounted or trailed, with tools powered by the engine of the tractor or by an auxiliary motor It is applicable regardless of the type of movement of the tools This standard is not applicable to: — spading machines; — pedestrian controlled soil working machines; — machines where the tools are driven by movement of the machine over the ground; — machines fitted with a retractable device, making them capable of working between two successive plants in the same row It describes methods for elimination or reduction of risks which need specific requirements for soil working machines with powered tools It does not deal with general hazards, particularly general hazards related to the mobility These aspects will be dealt with in a standard currently in preparation (EN 1553) In addition, it specifies the type of information on safe working practices to be provided by the manufacturer The list of significant hazards dealt with in this standard is given in Annex A Annex A also indicates the hazards which have not been dealt with ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ NOTE The measures for safeguarding the PTO shaft are dealt with in the “Common requirements” standard being prepared by CEN/TC 144 Environmental aspects have not been

being reached by the upper limbs EN 1553:1999, Agricultural machinery — Agricultural self-propelled, mounted, semi-mounted and trailed machines — Common safety requirements Definitions For the purposes of this standard, the following definition applies: soil working machine with powered tools machine with powered tools designed for modifying soil structure or profile and/or for incorporating plants, crop residues or animal manure during tillage NOTE Non-restrictive examples of such machines are given in Annex B © BSI 01-2001 EN 708:1996 Safety requirements and/or measures 4.1 General Machines shall comply as appropriate with EN 292 for hazards which are not dealt with 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 with Tables 1, 3, and of EN 294:1992 4.2 Protection against hazards related to moving parts 4.2.1 Protection against hazards related to moving power transmission parts To ensure protection against hazards related to accessible moving power transmission parts, the machine shall be fitted with fixed guards (according to 3.22.1 of EN 292-1:1991) When frequent access is foreseen, the machine shall be fitted with guards needing a tool for their opening These guards shall remain attached to the machine when opened (for example by means of hinges) and automatically lock in closed position without the use of a tool If this type of guard is not used, the machine shall be fitted with: — interlocking movable guards (according to 3.22.4 of EN 292-1:1991); or — movable guards fitted with a device which prevents their opening so long as the parts are moving 4.2.2 Protection against unintentional contact with the tools 4.2.2.1 Machines shall be designed or guarded in such a way that any unintentional contact with the powered tools at the front, at the rear, at the sides and on the top is avoided — At the front, at the sides and at the rear of the accessible zone, a barrier shall be placed at a maximum height of 400 mm from the lower tools path and at a minimum horizontal distance a of 200 mm from the tools path (see Figure and Figure 2) On the top, the area between the barriers shall be completely guarded: — the area which covers the tools at least up to the outer points of their path shall be guarded by an imperforate guard; — the area between the barriers and the edge of the top guard shall be guarded in such a way that it shall not be possible to pass a 61 mm spherical test gauge through this area The guarding may be –1 achieved by a guard or any part of the machine or a combination of both The test gauge shall be of mild steel and shall be applied by hand The machine and its guards shall be set in the most unfavourable positions The top guard, the barriers and the parts of the machine ensuring the guarding shall withstand a vertical downwards load of 200 N The barriers shall additionally withstand the following horizontal loads: — 600 N for machines with a horizontal axis intended to be used with a tractor whose maximum power as given in the instruction handbook is less than or equal to 37 kW; — 000 N for the other machines These requirements shall be checked by the test procedure and the test acceptance defined in Annex B of

compromise between the distances that were required in the CEN countries up until now It was noted that these distances have not been scientifically validated At present time this 200 mm distance leads to an improvement of the safety level in many CEN countries and consequently of the general safety level in Europe This value will be reviewed by the next revision of the standard on the basis of the result of relevant studies to be carried out On the sides, when in the working position a guard covers the parts of the tools above the ground, then the distance a may be less than 200 mm (see Figure 3) At the rear when the guard is hinged, its lower edge shall, whatever its position, be at a minimum distance d in accordance with Figure © BSI 01-2001 EN 708:1996 4.2.2.2 The guard at the rear may be retractable or removable, in order to permit the fitting of tools in accordance with the instructions of the manufacturer This protection at the rear may also be assured by other parts (e.g the frame) or by associated or combined equipment (e.g seed drills, rollers, harrows), providing they are not power driven 4.2.2.3 When a soil working machine with powered tools can be used without associated or combined equipment normally serving as a guard, in accordance with the instructions of the manufacturer, the machine shall be designed in such a way that the alternative guard (supplied by the manufacturer) can be fitted Key Path of the tools Guard ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ Figure — Lateral guard Dimensions in millimetres Figure — Rear protection-hinged guard 4.3 Protection for handling and transport The machines with folding elements shall be supplied with a mechanical locking device in the transport position The change from the working position to the transport position and vice versa shall occur without crushing and pinching hazard The movement of the folding elements shall be powered if the manual force needed for the manoeuvre exceeds 250 N The folding elements that can be manually moved shall be fitted with two handles located at a distance of at least 300 mm from the nearest articulation These handles may be integral parts of the elements, provided they are suitably designed and clearly identified © BSI 01-2001 EN 708:1996 In the case of powered operation, the control shall be of the hold-to-run type and the manual control shall be located outside the swivelling zone These requirements shall also apply to folding wheels fitted for transport, if any 4.4 Adjustment of the working depth It shall be possible for the operator to adjust the working depth by means of manual control(s) located: — on the machine and accessible by the operator standing on the ground; and/or — on the tractor and accessible only from the driving position For the manual control(s) located on the machine, the following requirements a), b), and c) shall be fulfilled: a) the adjustment shall be possible with the working tools stopped; b) the manual control(s) shall be located on the top, or on the sides, front or rear of the machine, at a maximum distance of 550 mm from the overall outer limits of the machine This distance shall be measured from the accessible zone (see Figure 1) parallel to the forward direction for manual controls accessible from the front or the rear of the machine, and at right angles to the forward direction for manual controls accessible from the sides; If the machine is so designed that rollers or other similar equipments can be used as an integral part of the machine during cultivation, the distance of 550 mm shall be measured from the outer edge of these equipments c) no manual control shall be located in the shaded area as shown in Figure 5a and Figure 5b These requirements apply to manual controls which need to be actuated when modifying the working depth according to the instruction handbook Verification of safety requirements and/or measures Dimensions, where given, shall be verified by measurements Controls shall be verified by a function test and positional measurements; guards by functional test Information for use 6.1 Instruction handbook Comprehensive instructions and
