Which of the following standard test procedures are mandatory components of the OECD Standard Code 2 / Nebraska Tractor Test for official tractor certification?
Options:
(A) PTO power and fuel consumption test across varying loads and speeds
(B) Drawbar pull, power, and travel reduction (wheel slip) test on a standardized concrete test track
(C) Hydraulic lift capacity test at the hitch points and on a standardized frame across the full lift range
(D) Measurement of operator station noise level under maximum load
Answer Key:
A, B, C, D
Step-by-Step Solution & Explanation
All four testing procedures are core requirements of the OECD Code 2 / Nebraska Tractor Test standards:
- PTO test (rated speed, maximum power, varying torque)
- Drawbar test on concrete track (drawbar power, slip, fuel economy)
- Hydraulic power and lift capacity test
- Acoustic noise measurement at the operator's ear level (ROPS cab/open station).
