BS EN 708:1997

National foreword
This British Standard has been prepared by Technical Committee AGE/32 and is
the English language version of EN 708:1996 Agricultural machinery — 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.

A British Standard does not purport to include all the necessary provisions of a
contract. Users of British Standards are responsible for their correct application.
Compliance with a British Standard does not of itself confer immunity

from legal obligations.

EN 708:1996


Introduction
The extent to which hazards are covered is indicated in the scope of this standard. These hazards are
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).

1 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.

EN 708:1996

4 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, 4 and 6 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 1 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 0 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 1 200 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;
— 1 000 N for the other machines.
These requirements shall be checked by the test procedure and the test acceptance defined in Annex B of
prEN 1553:1999.

NOTE This 200 mm distance is the result of a 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 4.

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.

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.

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.

5 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.

Annex A (normative)
List of hazards
Table A.1 gives the list of hazards based on EN 292-1:1991 and EN 292-2:1991 and Annex A of
EN 292-2:1991/A1:1995.
Table A.2 gives the list of hazards due to the mobility of the machine.
The meaning of the different statements given in the last column (solutions given by this standard) of these
tables are:
— “not relevant”: the hazard is not significant for the machine.
— “dealt with”: the hazard is significant. The measures given in the indicated clauses provide guidance
for dealing with the hazard in accordance with the principles of safety integration of EN 292; that means:
— elimination or reduction of the risk by design, as far as possible;
— protection measures;
— information for the residual risks.
— “partly dealt with”: the hazard is significant for several parts of the machine. The measures given in
the indicated clauses dealt with this hazard for some of these parts. In the other parts where the hazard
is significant, other measures, not included in this European Standard, will have to be applied in order
to deal with this hazard.
— “not dealt with”: the hazard is significant for the machine but has not been taken into account during
the preparation of this European Standard.
