4.3 Protection against ejection of projectiles other than parts of the machine
4.3.1 General
The mower shall be fitted with a protective device to prevent ejection of projectiles so that tests defined in 5.1
are satisfied.
NOTE This protective device may be for example canvas, rigid imperforate guard, chains or rubber strips.
In the case where this device consists of canvas, this canvas shall comply with the requirements of 5.2. In
addition, its attachment shall meet the following requirements:
11
---------------------- Page: 13 ----------------------
SIST EN 745:1999+A1:2009
EN 745:1999+A1:2009 (E)
if the canvas is clamped between two metal elements over its entire length, these elements shall not have
sharp edges where they come into contact with the canvas;
if the canvas is attached by being applied directly to a metal element, attachment devices (e.g. screws,
rivets .) shall be used with corresponding washers having a minimum diameter of four times the nominal
diameter of the attaching devices. These washers shall not have any sharp edges. The distance between
two attaching devices shall not exceed 250 mm;
if the canvas is attached indirectly (e.g. by sliding over a tube) attachment elements shall not have any
sharp edges.
Side protection may be made by skirts attached on their upper parts.
NOTE 2 The strength of the attachment of the canvas will be considered at the revision of the standard.
4.3.2 Additional requirements for offset mowers with one or several vertical axes attached at the rear
three-point tractor linkage
Between the innermost and outermost rotor axis, the protective device to prevent ejection of projectiles from
the top of the mower shall extend towards the front of the mower at least up to its intersection with the
imaginary line connecting points A and B (see figure 6).
Point A is located on a line parallel to the mower's forward direction. This line is located 900 mm from the
cutting path of the innermost rotor and 2 100 mm from the ground level. Point A is 1 750 mm in front of the
lower hitch point (see ISO 730-1) of the mower.
Point B is located where the line from point A, projected on the plan view, is tangent to the front part of the tool
path of the outermost rotor.

4.4 Protection during handling and transport
Machines with folding elements shall be supplied with a mechanical locking device for use in the transport
position. The change from the working position to the transport position and vice versa shall occur without
causing a crushing or pinching hazard. The movement of the folding elements shall be powered if the manual
force needed for the manoeuvre exceeds 250 N.
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.
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 any folding wheels fitted for transport.

4.5 Additional safety requirements for conditioning device fitted to mowers
4.5.1 The conditioning device shall be designed or guarded in such a way that any unintentional contact with
the tools at the rear, at the sides and on the top is prevented:
On the top by a rigid imperforate guard:
either the rear edge of this guard is located between 800 mm and 1 000 mm from the ground and
between 550 mm and 850 mm behind the tool path; in this case, the horizontal safety distance shall
be ensured further to the rear by a barrier located at least 850 mm behind the tool path and at a
distance between 800 mm and 1 000 mm from the ground (see figure 7a);
or the rear edge of this guard shall extend to the rear within the area as shown in figure 7b.
In the case of a conditioning device fitted on a mower attached at the front of the tractor, between the lower
hitch points the guard needs only to extend as far back as the rear edge of the tool path.

edge extends below the tool path by a minimum of 3 mm (see figure 8). Above point M, the guard shall
extend at least 200 mm beyond the tool path. Below point M, the guard shall not be above line W.

operate controls.
4.7 Blades
Blades shall comply with the requirements of clause 5 of ISO 5718-1:1989 or clause 4 of ISO 5718-2:1991.
NOTE The strength of the means of blade attachment will be considered at the revision of this standard.
5 Verification of safety requirements and/or measures
5.1 Stone ejection test
NOTE Round Robin tests will be carried out based on this test method. The results of these tests will possibly
indicate the need for the revision of this standard.
5.1.1 Testing conditions
5.1.1.1 General
Tests shall be performed on horizontal hard ground (e.g. concrete or asphalt).
Tests shall be performed using the same mower or mower with conditioning device and the same protective
devices. If the mower can be fitted with a removable conditioning device, the test shall be performed with and
without the conditioning device.
Adjustable devices (e.g. swath board) which may influence the efficiency of the protective device to prevent
projections shall be located in the least favourable position.
During tests, the mower shall be moved with a forward speed so that the tools run through the material at a
forward speed of between 2 km/h and 4 km/h.
5.1.1.2 Mounted, semi-mounted or trailed mowers
During tests, the mowers shall be driven at the speed recommended by the manufacturer (e.g. at power take-
off speed of 540 min-1 or 1 000 min-1) by the tractor A or the tractor B having the following characteristics
depending on the minimum power needed for the mower.
When the minimum power needed for the mower is more than 74 kW measured according to ISO 2288,
tractor A shall be used (see figure 9):
the horizontal distance between the axle of the rear wheels and the lower hitch point axis shall be 1 650
mm * 50 mm (lower link in an horizontal position);
the rear track, as defined in 3.1 of ISO 4004:1983, shall be adjusted to a maximum of 1 700 mm.
When the minimum power needed for the mower is less or equal to 74 kW measured according to ISO 2288,
tractor B shall be used (see figure 10):

the horizontal distance between the axle of the rear wheels and the lower hitch point axis shall be 1 500
mm * 50 mm (lower link in an horizontal position);
the rear track shall be adjusted to a maximum of 1 600 mm.
NOTE it may be necessary to modify the tractor to comply with these dimensions.
5.1.2 Target
