Larsen Tractor Test & Power Museum

The Lester F. Larsen Tractor Test and Power Museum is a museum dedicated to preserving and documenting the history of Nebraska's tractor test law, operated by the University of Nebraska–Lincoln in Lincoln, Nebraska, United States. The Nebraska Tractor Test Law, passed in 1919 and administered by the university, requires performance testing on every tractor with forty horsepower or more sold in the state. The facility, initially established as the Nebraska Tractor Test Laboratory, was renamed for longtime chief engineer Lester F. Larsen when it was converted into a museum in 1998. It is the only tractor testing museum and the only complete tractor test laboratory in the world.
