EXPLANATORY MEMORANDUM 

In  the  context  of  a  people’s  Europe,  the  Commission  attaches  great  importance  to 
simplifying  and  clarifying  Community  law  so  as  to  make  it  clearer  and  more 
accessible to the ordinary citizen, thus giving him new opportunities and the chance 
to make use of the specific rights it gives him. 

This aim cannot be achieved so long as numerous provisions that have been amended 
several times, often quite substantially, remain scattered, so that they must be sought 
partly  in  the  original  instrument  and  partly  in  later  amending  ones.  Considerable 
research work, comparing many different instruments, is thus needed to identify the 
current rules. 

For  this  reason  a  codification  of  rules  that  have  frequently  been  amended  is  also 
essential if Community law is to be clear and transparent. 

On  1  April  1987  the  Commission  therefore  decided1  to  instruct  its  staff  that  all 
legislative acts should be codified after no more than ten amendments, stressing that 
this  is  a  minimum  requirement  and  that  departments  should  endeavour  to  codify  at 
even  shorter  intervals  the  texts  for  which  they  are  responsible,  to  ensure  that  the 
Community rules are clear and readily understandable. 

The  Conclusions  of 
the  Edinburgh  European  Council 
(December 1992) confirmed this2, stressing the importance of codification as it offers 
certainty as to the law applicable to a given matter at a given time. 

the  Presidency  of 

Codification  must  be  undertaken  in  full  compliance  with  the  normal  Community 
legislative procedure. 

Given  that  no  changes  of  substance  may  be  made  to  the  instruments  affected  by 
codification, the European Parliament, the Council and the Commission have agreed, 
by  an  interinstitutional  agreement  dated  20  December  1994,  that  an  accelerated 
procedure may be used for the fast-track adoption of codification instruments. 

is 

this  proposal 

to  undertake  a  codification  of  Council 
The  purpose  of 
Directive 78/764/EEC  of  25  July  1978  on  the  approximation  of  the  laws  of  the 
Member  States  relating  to  the  driver's  seat  on  wheeled  agricultural  or  forestry 
tractors3. The new Directive will supersede the various acts incorporated in it4; this 
proposal  fully  preserves  the  content  of  the  acts  being  codified  and  hence  does  no 
more than bring them together with only such formal amendments as are required by 
the codification exercise itself. 

COM(87) 868 PV. 
See Annex 3 to Part A of the Conclusions. 
Carried out pursuant to the Communication from the Commission to the European Parliament and the 
Council – Codification of the Acquis communautaire, COM(2001) 645 final.

The codification proposal was drawn up on the basis of a preliminary consolidation, 
in all official languages, of Directive 78/764/EEC and the instruments amending it, 
carried out by the Office for Official Publications of the European Communities, by 
means  of  a  data-processing  system.  Where  the  Articles  have  been  given  new 
numbers,  the  correlation  between  the  old  and  the  new  numbers  is  shown  in  a  table 
contained in Annex VII to the codified Directive.

Seat tests 

(cid:208) 83/190/EEC Art. 1 and Annex 

2.5.1.  Determination  of the suspension characteristics and the range of adjustment to the 

driver's mass 

2.5.1.1.  The  suspension  characteristics  are  determined  by  a  static  test.  The  range  of 
adjustment  to  the  driver's  mass  is  calculated  from  the  suspension  characteristics. 
These  calculations  are  not  necessary  in  the  case  of  seats  that  cannot  be  manually 
adjusted to the driver's mass. 

(cid:208) 78/764/EEC 
(cid:206)1 83/190/EEC Art. 1 and Annex 

2.5.1.2.  The  seat  is  mounted  on  a  test  stand  or  on  a  tractor  and  a  load  applied  to  it,  either 
directly or by means of a special device; this load must not differ by more than 5 N 
from  the  nominal  load. (cid:206)1 The  measuring  error  for  the  suspension  travel  shall  not 
exceed ± 1 mm.  The load must be applied in accordance with the procedure laid 
down in section point 3 of Appendix 1. 

(cid:208) 83/190/EEC Art. 1 and Annex 
(adapted) 

2.5.1.3.  A complete characteristic curve representing the deflection of the suspension system 
must  be  plotted  from  zero  load  to  maximum  load,  and  back  to  zero.  The  load 
graduations  at  which  the  suspension  travel  is  measured  must  not  exceed  100 N;  at 
least  eight  measurement  points  must  be  plotted  at  approximately  equal  intervals  in 
the suspension travel. The point taken as the maximum load should ⌦ shall ⌫ be 
either  that  at  which  no  further  suspension  travel  can  be  measured,  or  a  load  of 
1 500 N. After each application or removal of the load, the suspension travel must be 
measured  200 mm  in  front  of  the  seat  reference  point  in  the  median  longitudinal 
plane of the seat surface. After application or removal of the load, the seat must be 
allowed to return to its at-rest position. 

2.5.1.4.  In  the  case  of  seats  with  a  mass  adjustment  scale,  the  characteristic  curves 
representing the deflection of the suspension system are plotted at mass adjustments 
for  drivers  having  a  mass  of  50  and  120 kg.  In  the  case  of  seats  without  a  mass 
adjustment  scale  and  with  adjustment  stops,  measurements  are  taken  at  the  lowest 
and the highest mass adjustment. In the case of seats without a mass adjustment scale 
or adjustment stops, the adjustment must be so selected that: 

2.5.1.4.1. 

for  the  lower  mass  adjustment  limit,  the  seat  just  returns  to  the  top  of  the 

suspension travel when the load is removed, and 

2.5.1.4.2. 

for the upper mass adjustment limit, the load of 1 500 N depresses the seat to 

the lowest limit of the suspension travel.

2.5.1.5.  The mean position of the suspension system is the position which the seat assumes 

when it is depressed by half the full travel of the suspension system. 

2.5.1.6.  Since  the  characteristic  curves  of  the  suspension  system  are  generally  hysteresis 
loops,  the  load  (cid:206)1  in  the  mean  position  of  the  suspension  system    must  be 
determined by drawing a centre line through the loop (see section point 8 of Annex I, 
and sections points A and B of Appendix 2 to Annex II). 

(cid:208) 83/190/EEC Art. 1 and Annex 
(adapted) 

2.5.1.7.  To determine the limits of the adjustment range as a function of the driver's mass, the 
vertical forces determined in accordance with Item point 2.5.1.6 for points A and B 
(see Appendix 2 to this Annex) must be multiplied by the scale factor 0,13 kg/N. 

2.5.2.  Determination of lateral stability 

2.5.2.1.  The seat must be set for the upper limit of the weight adjustment and connected to 
the test stand or to the tractor in such a way that its base plate rests on a rigid plate 
(test stand) not smaller than the base plate itself. 

(cid:208) 78/764/EEC 

2.5.2.2.  A test load of 1 000 N is applied to the surface or cushion of the seat. The point of 
application must lie 200 mm in front of the seat reference point (S) and alternately on 
the two sides 150 mm from the plane of symmetry through the seat. 

2.5.2.3.  During application of the load, the variation in the lateral angle of inclination of the 
seat  surface  is  measured  in  the  end  settings  for  horizontal  and  vertical  seat 
adjustment. The permanent deformation close to the point of application of the load 
is not to be taken into consideration. 

2.5.3.  Determination of the vertical vibration characteristics 

(cid:208) 83/190/EEC Art. 1 and Annex 

The seat vibration is determined by tests on a test stand and/or a standard roadway 
depending  on  whether  the  seat  is  intended  for  a  class  (or  classes)  of  Category  A 
tractor or for a Category B tractor.

2.5.3.1.1. 

The test stand must simulate the vertical vibrations at the point of attachment 
of  the  driver's  seat.  The  vibrations  are  generated  by  means  of  an  electro-hydraulic 
device. The set values to be used are either those specified in Appendices (cid:206)1 4, 5a 
and  5b ⌦ 4,  5  and  6 ⌫   to  Annex  II  for  the  class  of  tractor  in  question  or  the

B  tractor  moving  at  a  speed  of  12 ± 0,5 km/h  on  a  standard  roadway  as  defined  in 
Item point 2.5.3.2.1. To  generate the vibrations, an uninterrupted double run of the 
set values must be used. 

The transition from the end of the sequence of acceleration signals recorded on the 
standard roadway in the first run to the start of the second run must be smooth and 
jolt-free. The measurements must not be made during the first run of the set values or 
of the acceleration signals. More values than the 700 laid down in Appendices (cid:206)1 4, 
5a  and  5b  ⌦ 4,  5  and  6 ⌫   to  Annex  II  may  be  used  if  these  values  were 
calculated, for example, with a cubic Spline function from the original 700 values. 

2.5.3.1.2. 

Besides  an  attachment  for  the  test  seat,  the  platform  must  contain  a  steering 

wheel and footrest. Its configuration must be as shown in Appendix 67.

2.5.3.2.1. 

The roadway consists of two parallel strips spaced according to the wheel track 
of the tractor. Both strips must be made of a rigid material, such as wood or concrete, 
and  be  formed  either  of  blocks  set  in  a  base  structure  or  of  a  continuous  smooth 
surface.  The  longitudinal  profile  of  each  track  strip  is  defined  by  the  ordinates  of 
elevation  in  relation  to  a  base  level;  these  ordinates  are  shown  in  the  tables  in 
Appendix  3.  With  regard  to  the  roadway,  the  elevation  is  defined  at  intervals  of 
16 cm along each strip. 

The  roadway  must  be  firmly  set  in  the  ground  and  the  distance  between  the  strips 
must  deviate  only  slightly  over  its  entire  length;  the  tractor's  wheels  must  be  fully 
supported at all times. 

Where the strips are formed of blocks, these must be 6 to 8 cm thick, with a distance 
of 16 cm between the centres of the blocks. The length of the standard roadway shall 
be 100 m. 

The  measurements  must  begin  as  soon  as  the  axis  of  the  rear  axle  of  the  tractor  is 
perpendicular to point D = 0 on the roadway, and end as soon as the axis of the front 
axle of the tractor is perpendicular to point D = 100 of the test roadway (see the table 
in Appendix 3 to this Annex). 

2.5.3.2.2. 

Measurements shall be taken at a speed of 12 ± 0,5 km/h. 

The prescribed speed must be maintained without the use of brakes. The vibrations 
must  be  measured  on  the  seat  and  at  the  point  where  the  seat  is  attached  to  the 
tractor, with a light and a heavy driver. 

The speed of 12 km/h must be reached after a run-up track has been traversed. The 
surface of this run-up track must be flat and must join the standard roadway without 
any change in level.

The side-walls of the tyres must not be damaged. The pressure of the tyre must 
correspond to the arithmetical mean of the reference pressures recommended by the 
tyre  manufacturer.  The  wheel  track  must  correspond  to  that  used  under  normal 
working conditions for the tractor model on which the seat is fitted. 

2.5.3.2.7. 

The measurements at the point of seat attachment and on the seat itself must be 

made during the same run. 

For measuring and recording the vibrations, an accelerometer, a measuring amplifier 
and  a  magnetic  tape  recorder  or  direct-reading  vibration  meter  shall  be  used.  The 
specifications for these instruments are as laid down in points 2.5.3.3.2 to 2.5.3.3.6.

Appendix 1 

Method of determining the seat reference point (S) 

1. 

DEFINITION OF THE REFERENCE POINT (S) 

‘Seat reference point’ (S) means the point of intersection in the median longitudinal 
plane of the seat between the tangential plane at the base of the padded backrest and 
a  horizontal  plane.  This  horizontal  plane  intersects  the  lower  surface  of  the  seat 
150 mm in front of the seat reference point (S). 

2. 

DEVICE FOR DETERMINING THE SEAT REFERENCE POINT (S) 

The device illustrated in Figure 1 consists of a seat pan board and backrest boards. 
The  lower  backrest  boards  must  be  hinged  in  the  region  of  the  ischium  humps  (A) 
and the loin (B), the hinge (B) being adjustable in height. 

3. 

METHOD OF DETERMINING THE SEAT REFERENCE POINT (S) 

The  seat  reference  point  (S)  must  be  obtained  by  using  the  device  illustrated  in 
Figures 1 and 2, which simulates loading by a human occupant. The device must be 
positioned on the seat. It must then be loaded with a force of 550 N at a point 50 mm 
in front of hinge (A) and two parts of the backrest lightly pressed tangentially against 
the padded backrest. 

If it is not possible to determine definite tangents to each area of the padded backrest 
(below and above the lumbar region) the following procedure must be adopted: 

(a)  where  there  is  no  possibility  of  defining  the  tangent  to  the  lowest  possible 

area:, 

the  lower  part  of  the  backrest  board  in  a  vertical  position  must  be  lightly 
pressed against the padded backrest; 

(b)  where  there  is  no  possibility  of  defining  the  tangent  to  the  highest  possible 

area:, 

if the lower part of the backrest board is vertical, the hinge must be fixed at a 
height  of  230 mm  above  the  seat  reference  point  (S).  The  two  parts  of  the 
backrest  board  in  a  vertical  position  must  then  be  lightly  pressed  tangentially 
against the padded backrest.
