Drawbar is one of the important power outlet in agricultural tractors. It is the amount of useful power available at the drawbar for pulling implements, trailers, or other loads. In order to have a uniform practice in evaluating the drawbar power a need was felt to formulate this standard. This standard was first published in 1987. Subsequently, the standard was revised in 1995 deriving assistance from ISO 789-9: 1990 ‘Agricultural tractor — Test procedures — Power test for drawbar’.
2
The second revision of the standard incorporates the following modifications:
a) Definitions of wheelbase, rated engine speed, specific fuel consumption, and dynamic radius index have been incorporated directly into the standard, which were earlier referenced from IS 5994 : 1987 ‘Test code for agriculture tractors’
3
b) Following test requirements have been included:
i) Throttle lever shall be fully open during all tests unless specified otherwise.
ii) In case advance gearbox technology used, the tests shall be conducted in consultation with manufacturer.
iii) Upper limit of atmospheric temperature of 35 °C has been provided rather than range (25 ± 10 °C) for conducting tests.
