The Nebraska Tractor Test Laboratory (NTTL) at the University of Nebraska-Lincoln has played a key role in advancing agricultural machinery standards and helping producers make informed equipment decisions since 1920. Over the years, it has become a globally recognized center for independent tractor performance testing.
Located on the university's East Campus, the laboratory evaluates tractors and agricultural equipment for power output, fuel efficiency, safety, sound levels and hydraulic performance. Its testing process combines advanced engineering, specialized instrumentation and detailed data analysis.
The laboratory has tested more than 2,300 tractor models, with results made publicly available to help producers compare equipment performance and select machines that best fit their operations. The reports are also widely used to assess efficiency and operating costs.
According to laboratory director Eric Smith, "You can see what will give you the best return on your inputs for fuel, diesel and diesel exhaust fluid (injected into diesel tractor exhaust to reduce harmful emissions)."
The laboratory's influence extends beyond Nebraska, with manufacturers, agricultural organizations and producers around the world relying on its test data. More than 373,000 tractor test reports were downloaded in the past year from countries including Brazil, Italy, Ukraine, Kuwait and India.
Manufacturers use the laboratory's independent evaluations to compare their products against competing equipment. The data includes measurements such as power take-off performance, pulling power, hydraulic flow, sound levels and three-point hitch capabilities.
As agricultural equipment continues to evolve, the laboratory is adapting to technologies such as automation, advanced electronics and electrification. Researchers are working to ensure testing methods remain relevant for modern machinery and future innovations.
The laboratory also provides hands-on learning opportunities for engineering students. Through participation in equipment testing, instrumentation and data collection, students gain practical experience working on real-world agricultural engineering projects.
Its reputation for excellence dates back to 1920, when Nebraska established mandatory tractor testing to address concerns about equipment reliability. Today, organizations such as the OECD continue to draw on the laboratory's expertise when developing international tractor standards.
Beyond its technical contributions, the laboratory highlights the longstanding connection between farmers and their equipment. For many producers, tractors represent both productivity and a lifetime of work on the land.
