Proposal for a 
EUROPEAN PARLIAMENT AND COUNCIL DIRECTIVE 
on action to be taken against the emission of gaseous and particulate pollutants 
by engines intended to power agricultural or forestry tractors and amending 
Council Directive 74/150/EEC 

(presented by the Commission) 

EXPLANATORY  MEMORANDUM 

Road  traffic  has  long  been  recognized  as  being  a  major  source  of  air  pollution  by 
substances such as carbon monoxide (CO), unburned hydrocarbons (HC), nitrogen  oxides 
(Nox) and particulates (PT). Recent Commission studies show fairly clearly that emissions 
from  mobile  machinery,  essentially  operating  off  the  road,  and  agricultural  or  forestry 
tractors, are also  significant. 

The first European measures in this area were intended to reduce road-vehicle emissions in 
successive stages. More recently Parliament and the Council adopted  Directive 97/68/EC, 
which applies to off-road  mobile machinery, in order also to reduce the emissions by this 
in  stages.  The  sixth  recital  of  that  Directive  states  that  emissions  control  legislation  on 
agricultural  and  forestry  tractors  with  requirements  analogous  to  those  laid  down  for 
off-road  mobile machinery so as to ensure an equivalent level of environmental  protection 
should also be introduced as soon as possible. 

This proposal  covers those requirements.  They concern,  in particular,  the definition  of the 
component  type-approval  procedures  applying  to engines  intended  to be  fitted  to  tractors 
and thus also the definition  of the type-approval  procedures  for  such vehicles  in terms of 
their pollutant emissions. 

At  the  request  of  the  Member  States  and  interested  circles  it  was  agreed,  in  order  to 
achieve  economic  consistency  and  industrial  logic,  to  adopt  for  the  component 
type-approval  of  engines  and the  type-approval  of tractors  the  same test  requirements  as 
have  been  adopted  for  off-road  mobile  machinery,  together  with  the  corresponding  limit 
values for the emission levels. 

In  addition,  the  equivalence  between  the  technical  requirements  set  out  in  this  proposal 
concerning  stage  1 and those of UN/ECE  Regulation No 96 is recognized  with that  same 
industrial logic in mind in order to make it easier to enter third-country markets. Finally, in 
order  to  add  flexibility  to  the  engine  market  it  is  planned,  for  the  first  stage,  also  to 
recognize  the  technical  requirements  set  out  in Council  Directive  88/77/IWC  concerning 
emissions by diesel engines for use in vehicles. 

The  European  type-approval  of  tractors  that  has  gradually  been  built  up  since  1974  is 
based  on  framework  Directive  74/150/EEC, as last amended  by Directive  97/54/EC, and 
on  22  separate  directives.  The  aim  is to  create  a  single  approval  system  that  guarantees 
free movement within the Union. 

For  the  moment  implementation  of  the  Directives  and  full-vehicle  approval  remain 
optional. Each manufacturer  may thus decide freely  whether to use them or not. However, 
Where a choice is made to certify  either an engine that is intended to power tractors or else 
a tractor  in accordance with those Directives, the  Member States are required  to authorize 
the free movement of these. 

Those  22  separate  Directives  include  Council  Directive  77/537/EEC  relating  to  the 
measures  to  be  taken  against  the  emission  of  pollutants  from  diesel  engines  for  use  in 
tractors,  but  which  only  deals  with  the  opacity  of  the  exhaust  gases.  This  proposal 
supplements  that  Directive  77/537/EEC  by  drawing  a  distinction  between  the  four 
pollutant chemical components (CO, Nox , HC and PT). It is therefore  necessary to amend 
framework  Directive 74/15 0/EEC  in  order  to  add  a  further  heading  to  Annex II 
which  mentions  the  subject  covered  by  this  proposal,  together  with  the  code  SD 
(separate Directive.).

with the requirements of this Directive;

Whereas,  in  order  to  maximize  the  benefits  to  the  European  environment  and,  at 
the same time, to ensure the unity of the market, it is necessary  to adopt very strict 
mandatory  standards  at  regular  intervals;  whereas  any  further  reduction  in  the 
limit values and any changes to the test procedure can be adopted only on the basis 
of studies and research to be conducted  into existing and  foreseeable  technological 
potential and into the cost-effectiveness  of the options, in order to allow production 
on an industrial  scale of agricultural or forestry  tractors that are capable of meeting 
these  more  stringent  limits;  whereas  the  decision  regarding  any  such  subsequent 
reduction should be taken by Parliament and the Council by the end of 2006; 

Whereas  the  Member  States  should  be  allowed  to  grant  fiscal  incentives  to 
promote the introduction of engines intended to be fitted to agricultural  or  forestry 
tractors  which  meet  in  advance  the  requirements  adopted  at  Community  level 
concerning action to counter pollutant emissions; 

Whereas,  in  accordance  with  the  principles  of  subsidiarity  and  proportionality  as 
set  out  in  Article  3b  of  the  Treaty,  the  objectives  of  the  Community  measures 
envisaged  by this  Directive  cannot  be sufficiently  achieved  by the Member  States 
and  can  therefore  be  better  achieved  by  the  Community;  whereas  this  Directive 
confines  itself  to  the  minimum  required  in  order  to  achieve  those  objectives  and 
does not go beyond what is necessary for that purpose;

set out  in the  Annexes  to  this  Directive;  whereas, with  the  exception  of  the  limit 
values for pollutants, it is appropriate to delegate this task to the Commission, with

Article 1 

For the purposes of this Directive: 

"agricultural  or  forestry  tractor"  (hereinafter  referred  to  as  "tractor")  means  any 
vehicle as defined  in Article  1(1) of Directive 74/150/EEC; 

"engine"  means  any  internal  combustion  engine  intended  to  power  tractors,  as 
defined  in Annex I to this Directive; 

"component  type-approval  of  an  engine  type  or  family  in  respect  of  pollutant 
emissions"  means  the  instrument  whereby  a  Member  State  certifies  that  an 
engine  type or family  intended  to power tractors meets the technical  requirements 
of this Directive; 

"type-approval  of  a  tractor  type  in  respect  of  pollutant  emissions"  means  the 
instrument  whereby  a Member  State  certifies  that  a tractor  type  equipped  with  an 
engine as defined  in Annex I meets the technical requirements of this Directive; 

"family  of engines" means  two  or more types of engine  that  are  similar  in  design 
and  which, therefore,  could  display characteristics that are comparable  in terms of 
pollutant emissions. 

Article 2 

The  procedure  for  granting  component  type-approval  for  an  engine  type  or  family  in 
respect  of  pollutant  emissions,  the  procedure  for  granting  type-approval  for  tractors  in 
respect  of  pollutant  emissions,  and  the  conditions  for  the  unrestricted  placing  on  the 
market of such engines and tractors, shall  be as laid down in Directive 74/150/EEC. 

Article 3 

1. 

2. 

Any  engine  type  or  family  shall  meet  the  requirements  of  Annex I  in  respect  of 
pollutant emissions. 

Any  tractor  type  shall  meet  the  requirements  of  Annex II  in  respect  of 
pollutant emissions. 

1. 

As from 1  January 2001, Member States may not: 

Article 4 

refuse  to  grant  EC  component  type-approval  or  national  component 
type-approval in respect of an engine type or family, or 

prohibit the sale of such engines, 

if  the  pollutants  emitted  by  those  engines  meet  the  requirements  of  this 
Directive, or 

refuse  to grant EC type-approval or national type-approval of tractors, or 

prohibit the initial entry into service of tractors, 

if  the  pollutants  emitted  by  the  engine  fitted  to  those  tractors  meet  the 
requirements of this Directive. 

2. 

As from 1  October 2001, Member States: 

may no longer grant EC type-approval for a tractor type, 

shall refuse  to grant national type-approval for a tractor type, 

where the pollutants emitted by the engine fitted to that  tractor type do not 
meet the requirements of this Directive. 

3. 

As from  1 October 2003, Member States shall prohibit the initial entry into service 
of  tractors  where  the  pollutants  emitted  by  their  engines  do  not  meet  the 
requirements of this Directive. 

Article 5 

The  authorities  of  Member  States  granting  EC  component  type-approval  for  a  type  or 
family  of engines or EC type-approval  for  a type of tractor shall recognize the  component 
type-approvals or type-approvals  granted in accordance with the provisions of section 3 of 
Annex I  and  section 3  of  Annex II  and  the  corresponding  component  type-approval  or 
type-approval marks. 

Article 6 

On the basis of a proposal which the Commission  shall, if need be, put forward  by the end 
of  2004, the  European  Parliament  and  the Council  shall  decide  on a  further  reduction  in 
emission limit values by the end of 2006. In its proposal, drawn up on the basis of research 
and  cost/efficiency  assessments  of  the  application  of  more  stringent  limit  values,  the 
Commission will propose measures that are proportional  and reasonable with regard to the 
targets  set,  taking  account  of  the  overall  availability  of  techniques  for  controlling 

air-polluting  emissions  from  engines  and  the  incorporation  of  new  engine  systems  and 
accessories into tractors, and of the air-quality situation. 

Article 7 

1. 

2. 

Member  States  may  provide  tax  incentives  for  tractors  and  engines  that  are 
intended  to  power  such  tractors  only  where  they  comply  with  the  anti-pollution 
measures laid down in this Directive. 

The  incentives  referred  to  in  paragraph  1 shall  comply  with  the  provisions  of  the 
Treaty and fulfil  the following conditions: 

they shall be valid for  all new tractors and engines sold on the market  of a 
Member State which meet the requirements of this Directive in advance; 

they shall end with the mandatory application of the limit values laid down 
in this Directive; 

they shall, for  each type of tractor and engine, be lower than the extra cost 
of the technical  solutions introduced  and of fitting the engine to the tractor 
in such a way that the values laid down are not exceeded. 

3. 

The  Commission  shall  be  informed  of  any  plans  to  introduce  or  change  any  of 
the  tax  incentives  referred  to  in  the  first  paragraph  sufficiently  early  for  it  to 
comment thereon.

ESSENTIAL CHARACTERISTICS OF THE ENGINE FAMILY 

Common parameters defining  the engine family 

The  engine  family  may  be  defined  by  basic  design  parameters  which  must  be 
common  to  all  engines within  the  family.  In  some cases there may be  interaction  of 
parameters.  These  effects  must  also  be  taken  into  consideration  in  order  to  ensure 
that only engines with similar exhaust emission characteristics are included within an 
engine  family. 

For engines to  be considered  to belong to the  same engine  family,  the following  list 
of basic parameters must be common: 

Combustion  cycle: 2 stroke/4 stroke1 
Cooling medium: air/water/oil1 
Swept volume: 
- swept volumes to be within a total spread of  15% 
- the number of cylinders for engines with after-treatment  device must be identical 
Method of air aspiration: naturally aspirated/pressure charged1 
Combustion chamber type/design 
- pre-chamber 
- swirl chamber 
- open chamber 
Valve and porting - configuration,  size and number 
- cylinder head 
- cylinder wall 
-crankcase 
Fuel system 
- pump-linc-injector 
- in-line pump 
- distributor pump 
- single element 
- unit  injector

Choice of the parent engine 

The  parent  engine  of the  family  shall  be  selected  using the  primary  criterion  of  the 
highest  fuel  delivery  per  stroke  at  the  declared  maximum  torque  speed.  If  two  or 
more  engines  share  this  primary  criterion,  the  parent  engine  shall  be  selected  using 
the  secondary  criterion  of  highest  fuel  delivery  per  stroke  at  rated  speed.  Under 
certain  circumstances,  the  approval  authority  may  conclude  that  the  worst-case 
emission  rate  of  the  family  can  best  be  characterized  by  testing  a  second  engine. 
Thus,  the  approval  authority  may  select  an  additional  engine  for  tests  based  upon 
features  which  indicate  that  it  may  have  the  highest  emission  levels  of  the  engines 
within that  family. 

If  engines  within  the  family  incorporate  other  variable  features  which  could  be 
considered  to  affect  exhaust  emissions,  these  features  must  also  be  identified  and 
taken into account in the selection of the parent engine.

APPENDIX 3 

MARKING OF ENGINES 

1. 

Any engine approved as a separate technical unit must bear: 

1.1 

the trademark or trade name of the engine's  manufacturer; 

1.2 

the engine type, and if applicable engine family, and a unique engine  identification 
number; 

1.3 

the EC component type-approval number in accordance with Annex II. 

2. 

3. 

These marks must  last throughout  the useful  life  of the engine and  remain  clearly 
legible  and  indelible.  If  labels  or  plates  are  used,  they  must  be  affixed  in  such  a 
way that they too last throughout the useful  life of the engine, and the labels/plates 
cannot be removed without destroying or defacing them. 

These marks must be secured to an engine part that is necessary for  normal  engine 
operation and not normally requiring replacement during engine life. 

These marks must be located so as to be readily visible to the average person once 
the engine has been fitted to the tractor, together with all the accessories needed  for 
engine operation.  If a bonnet  is to be removed  in order to make the  mark  visible, 
this requirement  shall be considered to have been met if removal  of that bonnet  is 
simple and does not require the use of a tool. 

In case of doubt concerning the meeting of this requirement,  it shall be considered 
to have been met if an additional mark containing at least the engine  identification 
number and the name, trade name or logo of the manufacturer has been added. That 
additional  mark  shall be affixed  to, or next to, a major  component  that would  not 
normally  have  to  be  replaced  during  the  service  life  of  the  engine,  and  be  easily 
accessible, without the assistance  of tools, during routine maintenance  operations; 
otherwise,  it  must  be  located  at  a  distance  from  the  original  mark  on  the  engine 
crankcase.  The  original  mark  and,  where  appropriate,  the  additional  mark  shall 
both  be clearly  visible  once  all  of the  accessories  needed  for  the  operation  of  the 
engine  have  been  fitted.  A bonnet  meeting  the  requirements  set  out  in  the  above 
paragraph  shall  be  authorized.  The  additional  mark  shall  be  affixed  in  a  durable 
manner  directly  to  the  topside  of  the  engine,  for  example  by  means  of  an 
engraving, or a sticker or plate that meets the requirements of item 2. 

4. 

The engines must be classified  by means of their identification  numbers  in  such a 
way that the production sequence can be determined unambiguously. 

21 

5. 

6. 

Before  leaving the production line, the engines must bear all of the required marks. 

The  exact  location  of  the  engine  marks  shall  be  declared  in  the  information 
document, in accordance with Annexes I and II.
