It is assumed that the axle mounted with the wider tyres or tracks is set at a track width of not more than 1 150 mm. 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. Where the two axles are fitted with rims and tyres or tracks of the same size, the fixed or adjustable track width of the two axles must be less than 1 150 mm;\n2.1.3.\nmass greater than 400 kg but less than 3 500 kg, corresponding to the unladen mass of the tractor, including the roll-over protective structure and tyres or tracks of the largest size recommended by the manufacturer. The maximum permissible mass shall not exceed 5 250 kg and the Mass Ratio (Maximum Permissible Mass/Reference Mass) must not be greater than 1,75;’;\n(e) in point 3.1.2.3., the following sentence is added:\n‘In case of tractor fitted with tracks, the manufacturer shall define the tracks setting.’;\n(f) in point 3.1.3.2., the second and third sentence are replaced by the following:\n‘This angle must be at least 38° at the moment when the tractor is resting in a state of unstable equilibrium on the wheels or tracks touching the ground. Perform the test once with the steering wheel turned to full right lock and once with the steering wheel turned to full left lock.’;\n(g) point 3.1.4.3.1. is amended as follows:\n(i) the line for tractor characteristic B0 is replaced by the following:\n‘\nB0\n(m)\nRear tyre or track width;\n’;\n(ii) the lines for tractor characteristics D2 and D3 are replaced by the following:\n‘\nD2\n(m)\nHeight of front tyres or tracks under full axle load;\nD3\n(m)\nHeight of rear tyres or tracks under full axle load;\n’;\n(iii) in the line for tractor characteristic S, the words ‘The sum of the track (S) and tyre (B0) widths must be greater than the width B6 of the protective structure.’ are replaced by the words ‘The sum of the rear track width (S) and tyre or track (B0) widths must be greater than the width B6 of the protective structure.’;\n(h) point 3.1.4.3.2.2. is replaced by the following:\n‘3.1.4.3.2.2.\nthe axis of rotation is parallel to the tractor's longitudinal axis and passes through the centre of the contact surfaces of the downhill front and rear wheel or track;’;\n(i) in point 3.1.5.1., the last paragraph is replaced by the following:\n‘The distances between the centre of gravity and the rear axle (L3 ) or the front axle (L2 ) shall be calculated from the mass distribution of the tractor between the rear and the front wheels or tracks.’;\n(j) point 3.1.5.2. is replaced by the following:\n‘3.1.5.2.\nHeights of rear (D3 ) and front (D2 ) tyres or tracks\nThe 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.’;\n(k) in point 3.1.5.4., the last paragraph is replaced by the following:\n‘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).’;\n(l) in point 3.1.5.6., the last paragraph is replaced by the following:\n‘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.’;\n(m) in point 3.1.5.9., the first and second paragraph under the heading ‘Height of the front-axle pivot point (H0)’ are replaced by the following:\n‘The vertical distance between the centre of the front-axle pivot point to the centre of axle of the front tyres or tracks (H01 ) shall be included in the manufacturer's technical report and shall be checked.\nThe vertical distance from the centre of the front tyres or tracks axle to the ground plane (H02 ) shall be measured (Figure 6.8).’;\n(n) points 3.1.5.10. and 3.1.5.11. are replaced by the following:\n‘3.1.5.10.\nRear track width (S)\nThe minimum rear track width fitted with tyres or tracks of the largest size, as specified by the manufacturer, shall be measured (Figure 6.9).\n3.1.5.11.\nRear tyre or track width (B0 )\nThe 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).’;\n(o) point 3.2.1.3.4. is replaced by the following:\n‘3.2.1.3.4.\nThe 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.’;\n(p) point 3.2.2.2.4. is replaced by the following:\n‘3.2.2.2.4.\nIf the tractor is fitted with a suspension system between the tractor body and the wheels or tracks, it shall be blocked during the tests.’;\n(q) point 3.2.5.4. is replaced by the following:\n‘3.2.5.4.\nCrushing rig\nA 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.’;\n(r) in point 3.3.2.2., the last sentence of the last paragraph is replaced by the following:\n‘For estimating this, the front and rear tyres or tracks and track width setting shall be the smallest standard fitting specified by the manufacturer.’;\n(s) figure 6.5 is replaced by the following:\n‘ Figure 6.5\nData required for calculating the overturn of a tractor with triaxial rolling behaviour\nNote: D2 and D3 should be measured under full axle load.’;\n(t) in point 5.3.1., in the last paragraph, the following sentence is added:\n‘In the case of a tractor fitted with tracks, the manufacturer shall define the tracks setting.’;\n(u) in section B4 (‘Requirements for virtual testing’), the following paragraph is added:\n‘For tractor fitted with tracks, the following lines have to be substituted in the original model:\n520 LOCATE 12, 40: PRINT ‘HEIGHT OF THE REAR TRACKS D3=’\n*540 PRINT ‘HEIGHT OF THE FRT TRACKS D2=’: LOCATE 13, 29: PRINT ‘’\n650 LOCATE 17, 40: PRINT ‘REAR TRACKS WIDTH B0=’\n970 LPRINT TAB(40); ‘HEIGHT OF THE REAR TRACKS D3=’;\n*980 LPRINT ‘HEIGHT OF THE FRT TRACKS D2=’;\n1160 LPRINT TAB(40); ‘REAR TRACK WIDTH B0=’;\n1390 W2 = SQR(H0 * H0 + L0 * L0): S1 = S/2 + B0/2\n1530 F2 = 2 * ATN(- L0/D3 + SQR((L0/D3) ^ 2 – (D2/D3) + 1))\n1590 X(1, 5) = D3\n1660 Y(1, 5) = -L3\n*\nif applicable’;\n(2) in the Explanatory notes to Annex IX, explanatory note (1) is replaced by the following:\n‘(1)\nUnless 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.’.",
