12、1 1 Scope and field of application This International Standard lays down track widths for agricultural tractors and machinery, as a guideline for the manufacturers of these products. It applies to the principal driven axle(s) of agricultural tractors and to machinery, including self-propelled machin

13、ery, used in fields for row-crops. It does not apply to tractors of special types, to walking-tractors to single-axle motor-driven machines, to two-wheeled propulsion units, or to agricultural machinery of special types. 2 References ISO789-1, Agricultural tractors Test procedures Part1: Power tests

14、. 3 Definitions of track The following definitions are taken from ISO789-1. 3.1 track (tread) of wheeled tractor the distance at ground level between the median planes of the wheels on the same axle, with the tractor stationary and with the wheels in position for travelling in a straight line. The t

15、rack may be thus defined for both front and rear wheels. When there are twin wheels, the track is the distance between two planes each being the median plane of the pairs of wheels 3.2 track of tracklaying tractors the distance between the median planes of the tracks NOTEThe median plane of the whee

16、l or track assembly is equidistant from the two planes containing the peripheries of the rims or the track plates respectively at their outer edge. 4 Track widths The preferred track widths are the following: 1500 25mm 1800 25mm 2000 25mm NOTEIt is not envisaged that the tracks of all machines will

17、be capable of being set to all three widths.2 blankBS6508:1984 BSI 12-1999 Publication referred to See national foreword.BS6508:1984 ISO4004:1983 BSI 389 Chiswick High Road London W4 4AL BSIBritishStandardsInstitution BSI is the independent national body responsible for preparing BritishStandards.
