The '''Nebraska Tractor Test Laboratory''' (NTTL) is a program operated by the [[University of Nebraska]] in accordance with Nebraska law to test the performance of agricultural equipment that is to be sold in the United States for compliance with [[OECD]] standards. The NTTL has operated since 1920 as the common standard reference for tractor performance in the United States.
==History==
Impetus for the Nebraska Tractor Test Act of 1919, or Nebraska Tractor Law, came from a Nebraska farmer, Wilmot F. Crozier, who had been disappointed with the performance of several tractors he had bought. One had been marketed as a Ford tractor, but the [[Ford Tractor Company]] of the time was completely unrelated to the [[Ford Motor Company]], and its products were of poor quality. The new law was enacted to address problems of false advertising of tractor features and capabilities, requiring that all agricultural tractors sold in Nebraska must have their performance verified by three engineers. The laboratory was established in 1920 at the [[University of Nebraska]] as a central location for tractor testing.<ref name="pripps fr 7">{{cite book |last1=Pripps |first1=Robert N. |title=The Field Guide to Classic Farm Tractors |date=2020 |publisher=Motorbooks |isbn=978-0-7603-6844-2 |page=7}}</ref> The first tractor to be tested at the NTTL was a [[Waterloo Boy]], which passed the test.<ref name="histneb1">{{cite web |title=Tractor Testing in Nebraska |url=https://history.nebraska.gov/publications/tractor-testing-nebraska |website=History Nebraska |access-date=29 August 2021}}</ref><ref name="brown1">{{cite web |last1=Brown |first1=Candace |title=Nebraska Tractor Test |url=https://www.antiquepower.com/normal-blog/2015/10/05/nebraska-tractor-test |website=Antique Power |publisher=Erfel Publishing |access-date=29 August 2021 |date=October 5, 2015}}</ref>
All tractors sold in Nebraska had to be tested at the NTTL. In consequence, the Nebraska Tractor Test became a standard reference for tractors sold in North America.<ref name="unl1">{{cite web |title=The Story of the Larsen Tractor Museum |url=https://tractormuseum.unl.edu/story-larsen-tractor-museum |website=Lester F.

As [[power take-off]]s became available the tests included those features, and gradually expanded to include operating convenience, fuel consumption, and operator comfort.<ref name="brown1"/>
