COUNCIL DIRECTIVE
of 26May 1986
on rear-mounted roll-over protection structures of narrow-track
wheeled agricultural and forestry tractors
(86/298/EEC)
THE COUNCIL OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic
Community, and in particular Article 100 thereof,
Having regard to the proposal from the Commission(1),
Having regard to the opinion of the European Parliament(2),
Having regard to the opinion of the Economic and Social Committee(3),
Whereas Council Directive 74/150/EEC of 4 March 1974 on the
approximationof the laws of the Member States relatin g to the type-
approval of wheeled agricultural or forestry tractors(4), as last amended
by the Act of Accessionof Spainan d Portugal, lays downthat thenecessary provisions for the implementation of the EEC type-approvalprocedure inrespect of in dividual tractor parts or characteristics should
be specified in special directives; whereas the provisions relating to roll-
over protection structures and their attachments to tractors were laiddownby Directives 77/536/EEC(
5) and 79/622/EEC(6), as last amended
by the Act of Accessionof Spainan d Portugal; whereas these twoDirectives cover respectively dynamic and static testing procedures —either of which may be employed by manufacturers for the present —
and relate to standard tractors, that is, tractors having a maximum
ground clearance of 1 000 mm and a fixed or adjustable track width ofone of the driving axles of not less than 1 150 mm and weighingbetween 1,5 and 4,5 tonnes in the case of tractors covered by the‘dynamic testing’ Directive and not less than 800 kilograms in the caseof tractors covered by the ‘static testing’ Directive;
Whereas the tractors covered by this Directive have a maximum ground
clearance of 600 mm, a minimum track width of both axles of less than1 150 mm and a mass greater than 600 kilograms; whereas the roll-overprotectionstructures of these tractors, which are used for specificactivities, can be made subject to specific requirement or requirements
other thanthose of Directive 77/536/EEC an d 79/622/EEC;
Whereas the technical requirements with which such ‘narrow-track’
tractors must comply pursuant to national laws relate inter alia to roll-
over protection structures and to their attachment to the tractor; whereasthose requirements differ from one Member State to another; whereas it
is therefore necessary that all Member States adopt the same
requirements either in addition to or in place of their existing rules inorder, inparticular, to allow the EEC type-approval procedure whichwas the subject of Directive 74/150/EEC to be introduced in respect ofeach type of tractor;
Whereas this Directive covers roll-over protectionstructures of the rear-
mounted rollbar, frame or cab type having a zone of clearance whose
upper limit is 900 mm above the seat reference point in order to providea sufficiently large area or unobstructed space for the protection of thedriver; whereas another special Directive will be adopted in respect ofroll-over protection structures having two pillars mounted in front of the
driver;
Whereas a harmonized component type-approval procedure for roll-over
protection structures and their attachment to the tractor makes it possible1986L0298 — EN — 02.06.1986 — 000.001 — 2

for each Member State to check compliance with the common
construction and testing requirements and to inform the other MemberStates of its findings by sending them copies of the component type-
approval certificate completed for each type of roll-over protection
structure and its attachment to the tractor; whereas the placing of anEEC component type-approval mark on all structures manufactured inconformity with the approved type obviates any need for technicalchecks onthose structures inthe other Member States; whereas common
requirements concerning other elements and characteristics of the roll-
over protection structure, in particular, devices to prevent continuousroll-over if the tractor overturns, and protection of occupants, will belaid downat a later date;
Whereas the harmonized requirements are intended principally to ensure
safety on the road and at work throughout the Community; whereas, for
this reason, it is necessary to introduce the obligation for tractors
covered by this Directive to be fitted with roll-over protectionstructures;
Whereas the approximation of the national laws relating to these tractors
entails reciprocal recognition by Member States of the checks carriedout by each of them onthe basis of the commonrequiremen ts,

ANNEX II
CONDITIONS FOR TESTING THE STRENGTH OF PROTECTION
STRUCTURES AND THEIR ATTACHMENT TO TRACTORS
1. GENERAL REQUIREMENTS
1.1. Test purposes
Tests made using special rigs are intended to simulate such loads as
are imposed ona protectionstructure, whenthe tractor overturn s.
These tests, described in Annex III, enable observations to be made
on the strength of the protection structure and any brackets attaching
it to the tractor and any parts of the tractor which transmit the test
force.
1.2. Test methods
Tests may be performed in accordance with the dynamic procedure
(see Annexes II A and III A) or the static procedure (see Annexes II B
and III B) at the manufacturer's choice.
The two methods are equivalent.
1.3. General rules governing preparation for tests
1.3.1. The protectionstructure must con form to the series production
specifications. It shall be attached in accordance with the manufac-
turer's recommended method to one of the tractors for which it is
designed.
Acomplete tractor is not required forthe strength test in static testing;
however, the protectionstructure an d parts of the tractor to which it is
attached shall represent an operating installation, hereinafter referred
to as ‘the assembly’.
1.3.2. For the strength test the tractor must be fitted with all series
production components which may affect the strength of the
protection structure or which may be necessary for the strength test.
Components which may create a hazard in the zone of clearance must
also be fitted so that they may be examined to see whether the
requirements of Items 3.1 and 3.2 have been fulfilled.
All components of the tractor or the protection structure including
weather protection must be supplied or defined in drawings.
1.3.3. For the strength tests, all detachable windows, doors, panels and non-
structural fittings must be removed so that they may not contribute to
the strengthening of the protection structure.
1.3.4. Track width
The track width shall be adjusted such that the protectionstructure
will, as far as possible, not be supported by the tyres during the
strength tests. If these tests are conducted in accordance with the
static procedure, the wheels may be removed.
1.4. Tractor reference mass
The reference mass ‘mt’, used in the formulae (see Annex III A and
III B) to calculate the height of fall of the pendulum block, the
loading energies and the crushing forces, shall be at least that defined
in Item 2.4 of Annex I to Council Directive 74/150/EEC (i.e.
excluding ‘optional’ accessories but including coolant, oils, fuel, tools
and driver) plus the protection structure and less 75 kilograms. Not
included are ‘optional’ front or rear weights, tyre ballast, mounted
implements, mounted equipment or any specialized component.
2. TESTS
2.1. Sequence of tests
The sequence of tests, without prejudice to the additional dynamic
and static tests (Annex III A and Annex III B), is as follows:
2.1.1. Impact (dynamic tests) or loading (static tests) at the rear of the
structure (see Item 1.1 of Annexes III A and III B)1986L0298 — EN — 02.06.1986 — 000.001 — 9

body and the wheels, it shall be blocked during the tests.
2.2.5. The side chosenfor applicationof the first impact onthe rear of the
structure (inthe case of dyn amic tests) or the first load onthe rear of
the structure (inthe case of static tests) shall be that which, inthe
opinion of the testing authorities will result in the application of the
series of impacts or loads under the most unfavourable conditions for
the structure. The lateral impact or load and the rear impact or load
shall be on different sides of the longitudinal median plane of the
protectionstructure. The fron t impact or load shall be onthe same
side of the longitudinal median plane of the protection structure as the
lateral impact or load.

the elastic deflection(the differen ce betweenthe maximum
momentary deflection and the permanent deflection).
8.2. A device for checking that the protection structure has not entered the
zone of clearance and that the latter has remained within the
structure's protection during the test (see Item 3.2.2 of Annex III A).
B.APPARATUS AND EQUIPMENT FOR STATIC TESTS
1. STATIC TESTING RIG
1.1. This rig shall enable horizontal thrusts or loading to be applied to the
structure.
1.2. Provisionmust be made so that the load canbe un iformly distributed
normal to the direction of loading and along a beam having a length
of one of the exact multiples of 50, between 250 and 700 mm.
The stiff beam shall have a vertical face dimension of 150 mm.1986L0298 — EN — 02.06.1986 — 000.001 — 12
▼B
The edges of the beam incon tact with the protectionstructure shall be
curved, with a maximum radius of 50 mm.
1.3. The pad shall be capable of being adjusted to any angle in relation to
the directionof the force, inorder to be able to follow the an gular
variations of the structure's load-bearing surface as the structure
deflects.
1.4. Direction of the force (deviation from horizontal and vertical)
— at start of test, under zero load: ± 2º,
— during test, under load: 10º above and 20º below the horizontal.
These variations must be kept to a minimum.
1.5. The deflectionrate shall be slow (less than5 mm/s) so that the load
may at all moments be considered as ‘static’.
2. APPARATUS FOR MEASURING THE ENERGY ABSORBED BY
THE STRUCTURE
2.1. The ‘force versus deflection’ curve shall be plotted in order to
determine the energy absorbed by the structure. There is no need to
measure the force and deflection at the point where the load is applied
to the structure; however, ‘force’ and ‘deflection’ shall be measured
simultaneously and co-linearly.
2.2. The point of origin of deflection measurements shall be selected such
that only the energy absorbed by the structure and/or the deflection of
certain parts of the tractor is taken into account. The energy absorbed
bythe deflection and/or the slipping of the anchoring shall be ignored.
3. MEANS OF ANCHORING THE TRACTOR TO THE GROUND
3.1. The tractor shall be anchored to the ground by means of restraining
and tensioning devices with rails rigidly attached to a non-yielding
base. The rails shall be anappropriate width apart to en able the tractor
to be lashed. During each test, the wheels and the axle stands used
shall rest onthe base.
3.2. The tractor shall be anchored to the rails by any suitable means
(plates, wedges, wire ropes, jacks, etc.) such that it cannot moveduring the tests. This requirement shall be checked while the loads are
being applied, by means of the usual devices for measuring length. If
the tractor moves, the entire test shall be repeated, unless the system
for measuring the deflections used in plotting the ‘force versus
deflection’ curve is connected to the tractor.
4. CRUSHING RIG
A rig as shown in Figure 8 of Annex IV shall be capable of exerting a
downward force on a protection structure through a rigid beam
approximately 250 mm wide connected to the load-applying
mechanism by means of universal joints. Suitable axle stands shall
be provided so that the tractor tyres do not bear the crushing force.
5. OTHER MEASURING APPARATUS
5.1. A device such as that illustrated in Figure 9 of Annex IV, for
measuring the elastic deflection (the difference between the
maximum momentary deflection and the permanent deflection).
5.2. A device for checking that the protection structure has not entered the
zone of clearance and that the latter has remained within the
structure's protection during the test (see Item 3.2.2 of Annex III B).

ANNEX III
TEST PROCEDURE
A.Dynamic tests
1. IMPACT AND CRUSHING TESTS
1.1. Impact at the rear
1.1.1. The tractor shall be so placed inrelationto the pen dulum block that
the block will strike the protectionstructure whenthe impact face of
the block and the supporting chains or wire ropes are at an angle with
the vertical plane equal to mt/100 with a 20º maximum, unless, during
deflection, the protection structure at the point of contact forms a
greater angle to the vertical. In this case the impact face of the block
shall be adjusted by means of an additional support so that it is
parallel to the protectionstructure at the poin t of impact at the
moment of maximum deflection, the supporting chains or wire ropes
remaining at the angle defined above.
The suspended height of the block shall be adjusted, and necessary
steps taken so as to prevent the block from turning about the point of
contact.
The point of impact shall be that part of the protection structure likely
to hit the ground first in a rearward overturning accident, normally the
upper edge. The positionof the cen tre of gravity of the block shall be
one-sixth of the width of the top of the protection structure inwards
from a vertical plane parallel to the median plane of the tractor
touching the outside extremity of the top of the protection structure.
If the structure is curved or protruding at this point, wedges enabling
the impact to be applied thereonwill have to be added, without
thereby reinforcing the structure.
1.1.2. The tractor shall be lashed to the ground by means of four wire ropes,
one at each end of both axles, arranged as indicated in Figure 5 of
Annex IV. The front and rear lashing points shall be located at a
distance such that the wire ropes make an angle of less than 30º with
the ground. The rear lashings shall in addition be so arranged that the
point of convergence of the two wire ropes is located in the vertical
plane in which the centre of gravity of the block travels.
The wire ropes must be tensioned such that the tyres undergo the
deflections given in Item 6.2 of Annex II A.
With the wire ropes tensioned, the wedging beam shall be placed in
front of and tight against the rear wheels and then fixed to the ground.
1.1.3. If the tractor is of the articulated type, the point of articulation shall,
inaddition , be supported by a woodenblock at least 100 mm square
and firmly lashed to the ground.
1.1.4. The pendulum block shall be pulled back so that the height of its
centre of gravity above that at the point of impact is given by one of
the following two formulae:
H¼2;165/C210/C08mtL2or H¼5;73/C210/C02I:
The block must thenbe released so as to strike the protection
structure.
1.2. Impact at the front
1.2.1. The tractor shall be so placed inrelationto the pen dulum block that
the block will strike the protectionstructure whenthe impact face of
the block and the supporting chains or wire ropes are at an angle with
the vertical plane, equal to mt/100 with a 20º maximum, unless,
during deflection, the protection structure at the point of contact
formsa greater angle to the vertical. In this case the impact face of the
block shall be adjusted by means of an additional support so that it is
parallel to the protectionstructure at the poin t of impact at the
moment of maximum deflection, the supporting chains or wire ropes
remaining at the angle defined above.1986L0298 — EN — 02.06.1986 — 000.001 — 15
▼B
The suspended height of the pendulum block shall be adjusted and
necessary steps taken so as to prevent the block from turning about
the point of contact.
The point of impact shall be that part of the protection structure likely
to hit the ground first if the tractor overturns sideways while
travelling forward, normally the upper edge. The position of thecentre
of gravity of the block shall be one-sixth of the width of the top of the
protection structure inwards from a vertical plane parallel to the
median plane of the tractor touching the outside extremity of the top
of the protectionstructure.
If the structure is curved or protruding at this point, wedges enabling
the impact to be applied thereonwill have to be added, without
thereby reinforcing the structure.
1.2.2. The tractor shall be lashed to the ground by means of four wire ropes,
one at each end of both axles, arranged as indicated in Figure 6 of
Annex IV. The front and rear lashing points shall be located at a
distance such that the wire ropes make an angle of less than 30º with
the ground. The rear lashings shall, in addition, be so arranged that
the point of convergence of the two wire ropes is located in the
vertical plane in which the centre of gravity of the pendulum block
travels.
The wire ropes must be tensioned such that the tyres undergo the
deflections given in Item 6.2 of Annex II A.
With the wire ropes tensioned, the wedging beam shall be placed
firmly behind the rear wheels and then fixed to the ground.
1.2.3. If the tractor is of the articulated type, the point of articulation shall in
additionbe supported by a woodenblock at least 100 mm square an d
firmly lashed to the ground.
1.2.4. The pendulum block shall be pulled back so that the height of its
centre of gravity above that at the point of impact is given by one of
the following two formulae, to be chosen according to the reference
mass of the tractors subjected to the tests:
H = 25 + 0,07 mtfor tractors with a reference mass of less than 2 000
kilograms,
H = 125 + 0,02 mtfor tractors with a reference mass of more than
2 000 kilograms.
The pendulum block must then be released so as to strike the
protectionstructure.
1.3. Impact from the side
1.3.1. The tractor shall be so placed inrelationto the pen dulum block that
the block will strike the protectionstructure whenthe impact face of
the weight and the supporting chains or wire ropes are vertical unless,
during deflection, the protection structure at the point of contact
forms anan gle to the vertical. Inthis case the impact face of the block
shall be adjusted by means of an additional support so that it is
parallel to the protectionstructure at the poin t of impact at the
moment of maximum deflection, the supporting chains or wire ropes
remaining vertical on impact.
The suspended height of the block shall be adjusted and necessary
steps taken so as to prevent the block from turning about the point of
contact.
The point of impact shall be that part of the protection structure likely
to hit the ground first in a sideways overturning accident, normally
the upper edge. Unless it is certain that another part of this edge
would hit the ground first, the point of impact shall be in the plane at
right angles to the median plane and passing 200 mm in front of the
seat reference point, the seat being set at the mid position of the
longitudinal seat adjustment.
1.3.2. The tractor wheels onthe side which is to receive the impact shall be
lashed to the ground by means of wire ropes passing over the
corresponding ends of the front and rear axles. The wire ropes shall be
tensioned to produce the tyre deflection values given in Item 6.2 of
Annex II A on the side which is to receive the impact.
With the wire ropes tensioned, the wedging beam shall be placed on
the ground, pushed tight against the tyres on the side opposite that

▼B
necessary to use two beams or wedges if the outer sides of the front
and rear tyres are not in the same vertical plane.
The prop shall then be placed as indicated in Figure 7 of Annex IV
against the rim of the wheel opposite to the impact, pushed firmly
against the rim and then fixed at its base.
The length of the rop shall be chosen such that it makes an angle of
30 ± 3º with the ground when in position against the rim. In addition,
its length must, if possible, be between 20 and 25 times greater than
its thickness and its width between two and three times greater than
its thickness. The props shall be shaped at both ends as shown in the
details of Figure 7 of Annex IV.
1.3.3. If the tractor is of the articulated type, the point of articulation shall,
inaddition , be supported by a woodenblock at least 100 mm square
and laterally supported bya device similar to that provided for in Item
1.3.2 against the rear wheel. The point of articulation shall then be
lashed firmly to the ground.
1.3.4. The pendulum block shall be pulled back so that the height of its
centre of gravity above that at the point of impact is given by one of
the following two formulae, to be chosen according to the reference
mass of the tractors subjected to the tests:
H = 25 + 0,20 mtfor tractors with a reference mass of less than 2 000
kilograms,
H = 125 + 0,15 mtfor tractors with a reference mass of more than
2 000 kilograms.
The pendulum block must then be released so as to strike the
protectionstructure.

The beam shall be positioned over the rear uppermost structural
member(s) and the resultant of the crushing forces shall be located in
the tractor's medianplan e.
A force, Fv=2 0mtshall be applied.

full crushing force, the force shall be applied until the roof is
deflected to coincide with the plane joining the upper part of the
protectionstructure with that part of the rear of the tractor capable of
supporting the vehicle's mass when overturned.
The force shall then be removed, and the tractor or loading force
repositioned so that the beam is over that point of the protection
structure which would thensupport the tractor whencompletely
overturned.
The force Fvshall thenbe applied.
It shall be applied for a minimum of five seconds following the
cessation of any visually detectable deflection.
1.5. Crushing at the front
The beam shall be positioned over the front uppermost structural
member(s) and the resultant of the crushing forces shall be located in
the tractor's medianplan e.
A force, Fv=2 0mtshall be applied.

the full crushing force, the force shall be applied until the roof is
deflected to coincide with the plane joining the upper part of the
protectionstructure with that part of the fron t of the tractor capable of
supporting the vehicle's mass when overturned.
The force shall then be removed, and the tractor or loading force
repositioned so that the beam is over that point of the protection
structure which would thensupport the tractor whencompletely
overturned.
The force Fvshall thenbe applied.
It shall be applied for a minimum of five seconds following the
cessation of any visually detectable deflection.1986L0298 — EN — 02.06.1986 — 000.001 — 17
▼B
1.6. Additional tests
If cracks or tears which cannot be considered negligible appear during
a crushing test, a second similar crushing test, but with a force equal
to 1,2 Fv, shall be applied immediately after the crushing test which
