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.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 1070 apply together with the
following:
3.1
inter-row mowing unit
rotary mower with vertical spindles equipped with pivoting boom, which allows grass cutting in the area between
two successive obstructions (e.g. trees, posts, etc.) (see Figure 1)
3.2
pivoting boom
device which allows the inter-row mowing unit to perform lateral translation movements parallel to the ground, thus
allowing cutting within the area between two successive obstructions which would not be possible using fixed
mowing machines (see Figure 1)
3.3
sensor
device controlling boom movement, mounted forward of the inter-row mowing unit
NOTE The device may be formed of a metal rod which, when pushed backwards on encountering an obstruction, sends a
command causing the boom to retract. 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

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.

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.
