Drawbarisone ofthe importantpoweroutletin agricultural tractors. In orderto have a uniform practice in evaluating the drawbar power a need was felt to formulate this standard. This standardwasfirst publishedin 1987. In orderto align the test procedurewith latestISO Standard this standard hasbeen revised. In preparationofthis standard. assistance has been derived from ISO 789-9 :1990, Agricultural. Tractor- Test procedures- Powertestfor drawbarissued bythe International Organization for Standardization(ISO). This revision incorporatesamongotherthe following: a) Generallayoutofthe standard; b) Definition of the terms such as tractor mass, rated engine speed, drawbar power~ maximumdrawbarpull, SFC and dynamic radiusindex; c) Permissibletolerancesfor the measurementlimit, d) Running..in and preliminaryadjustment, e) Specificationoffuel to be used for testing, f) Ambientair temperature20°± ISoC, g) Methodfor measurementoffuel consumption,and h) Statementofpowerrating.
