Subtopic: Power efficiencies and measurement, engine performance curves
Question Statement:
Under standard OECD and BIS Tractor Test Codes, which of the following performance tests are MANDATORY for official tractor type approval?
Options:
(A) Main PTO power and fuel consumption test
(B) Drawbar power and wheel slip test on concrete test track
(C) Hydraulic lift capacity and relief valve pressure test
(D) High-speed desert endurance run exceeding $100\text{ km/h}$
Answer Key:
A, B, C
Step-by-Step Solution & Explanation
OECD / BIS standard test codes mandate tests for PTO power and fuel consumption, drawbar power and slip on a standardized concrete track, hydraulic lift capacity at hitch points, braking, and noise levels. High-speed racing tests are not part of tractor test codes.
