Answer 1

Correct option is (a) Hitch between tractor and the pulling load

Explanation: Drawbar pull is determined by means of suitable dynamometer, inserted at the hitch between the tractor and the pulling load. For drawbar testing, the load on the back of the tractor has to be varied and hence a loading car is used.
