It must be possible to set the track width of the other axle in such a way that the outer edges of the narrower tyres or tracks do not go beyond the outer edges of the tyres or tracks of the other axle.

Heights of rear ( D 3 ) and front ( D 2 ) tyres or tracks The distance from the highest point of the tyre or tracks to the ground plane shall be measured (Figure 6.5), and the same method shall be used for the front and rear tyres or tracks.’; (k) in point 3.1.5.4., the last paragraph is replaced by the following: ‘The point of impact is defined by the plane tangent to the protective structure passing through the line made by the top outer points of the front and rear tyres or tracks (Figure 6.7).’; (l) in point 3.1.5.6., the last paragraph is replaced by the following: ‘The point of impact is defined by the plane tangent to the engine bonnet and the protective structure passing through the top outer points of the front tyre or track (Figure 6.7). The measurement shall be made on both sides of the engine bonnet.’; (m) in point 3.1.5.9., the first and second paragraph under the heading ‘Height of the front-axle pivot point (H 0 )’ are replaced by the following: ‘The vertical distance between the centre of the front-axle pivot point to the centre of axle of the front tyres or tracks ( H 01 ) shall be included in the manufacturer's technical report and shall be checked. The vertical distance from the centre of the front tyres or tracks axle to the ground plane ( H 02 ) shall be measured (Figure 6.8).’; (n) points 3.1.5.10. and 3.1.5.11. are replaced by the following: ‘3.1.5.10. Rear track width ( S ) The minimum rear track width fitted with tyres or tracks of the largest size, as specified by the manufacturer, shall be measured (Figure 6.9). 3.1.5.11. Rear tyre or track width ( B 0 ) The distance between the outer and the inner vertical planes of a rear tyre or track in its upper part shall be measured (Figure 6.9).’; (o) point 3.2.1.3.4. is replaced by the following: ‘3.2.1.3.4. The track width must be adjusted so that the protective structure will, as far as possible, not be supported by the tyres or tracks during the strength tests. If these tests are conducted in accordance with the static procedure, the wheels or tracks may be removed.’; (p) point 3.2.2.2.4. is replaced by the following: ‘3.2.2.2.4. If the tractor is fitted with a suspension system between the tractor body and the wheels or tracks, it shall be blocked during the tests.’; (q) point 3.2.5.4. is replaced by the following: ‘3.2.5.4. Crushing rig A rig as shown in Figure 6.10 shall be capable of exerting a downward force on a protective structure through a rigid beam approximately 250 mm wide, connected to the load-applying mechanism by means of universal joints. Suitable axle stands must be provided so that the tractor tyres or tracks do not bear the crushing force.’; (r) in point 3.3.2.2., the last sentence of the last paragraph is replaced by the following: ‘For estimating this, the front and rear tyres or tracks and track width setting shall be the smallest standard fitting specified by the manufacturer.’; (s) figure 6.5 is replaced by the following: ‘ Figure 6.5 Data required for calculating the overturn of a tractor with triaxial rolling behaviour Note: D2 and D3 should be measured under full axle load.’; (t) in point 5.3.1., in the last paragraph, the following sentence is added: ‘In the case of a tractor fitted with tracks, the manufacturer shall define the tracks setting.’; (u) in section B4 (‘Requirements for virtual testing’), the following paragraph is added: ‘For tractor fitted with tracks, the following lines have to be substituted in the original model: 520 LOCATE 12, 40: PRINT ‘HEIGHT OF THE REAR TRACKS D3=’ *540 PRINT ‘HEIGHT OF THE FRT TRACKS D2=’: LOCATE 13, 29: PRINT ‘ ’ 650 LOCATE 17, 40: PRINT ‘REAR TRACKS WIDTH B0=’ 970 LPRINT TAB(40); ‘HEIGHT OF THE REAR TRACKS D3=’; *980 LPRINT ‘HEIGHT OF THE FRT TRACKS D2=’; 1160 LPRINT TAB(40); ‘REAR TRACK WIDTH B0=’; 1390 W2 = SQR(H0 * H0 + L0 * L0): S1 = S/2 + B0/2 1530 F2 = 2 * ATN(- L0/D3 + SQR((L0/D3) ^ 2 – (D2/D3) + 1)) 1590 X(1, 5) = D3 1660 Y(1, 5) = -L3 * if applicable’; (2) in the Explanatory notes to Annex IX, explanatory note (1) is replaced by the following: ‘(1) Unless the numbering of sections B2 and B3 which has been harmonised with the whole Annex, the text of the requirements and the numbering set out in point B are identical with the text and numbering of the OECD standard Code for the official testing of front mounted roll-over protective structures on narrow-track agricultural and forestry tractors, OECD standard Code 6, Edition 2017 of February 2017.’.
