3 Definitions
For the purpose of this standard, the definitions given in EN 292-1:1991 and EN 292-2:1991 apply together
with the following.
NOTE Annex D.1 gives illustrations of mowers and components.
3.1
rotary mower
Mower that cuts the grass without mulching it so that it can subsequently be picked up
3.2
flail mower
Mower that cuts the grass and mulches it with the same tools, the mulched grass being left on the soil
3.3
conditioning device
Mechanical device for accelerating the crop drying process
3.4
swath board
Adjustable device for controlling the swath width
3.5
rigid imperforate guard
Inflexible guard without holes
3.6

Mower where each cutting head rotates about a vertical axis
3.7
horizontal axis mower
Mower where the tools rotate about a horizontal axis
4 Safety requirements and/or measures
4.1 General
The machinery 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 prEN
1553:1998 and with tables 1, 3, 4 and 6 of EN 294:1992.
4.2 Protection against unintentional contact with the tools
4.2.1 General
The mower shall be designed or guarded in such a way that any unintentional contact with the tools at the
front, at the rear, at the sides and on the top is prevented:
4.2.1.1 Vertical axes mower
 The top protection shall be achieved by a rigid imperforate guard or by the device used to prevent
projections (see 4.3);
 At the sides, the protection shall be achieved by:
 a barrier located in such a way that the distances defined in figure 1 are respected. These distances
are measured from the tool path and with the mower in working position, the cutting height being
adjusted at 50 mm or as near as possible to 50 mm;
This barrier may be removable or folded for transport. The removal of the barrier shall only be possible by
use of a tool;
and/or
 a rigid imperforate guard, located near the tools and in such a way that its lower edge extends below
the tool path by a minimum of 3 mm (see figure 2);
 On the front and at the rear, the protection shall be achieved by a barrier located in such a way that the
distances as defined in figure 1 are respected.
