The Lester F. Larsen Tractor Test and Power Museum is a historical facility located on the East Campus of the University of Nebraska–Lincoln in Lincoln, Nebraska, United States. The museum was established in 1980 and is dedicated to preserving and documenting the history of Nebraska's tractor test law (dating from 1919) which began as a law to protect others from irresponsible tractor companies failing to keep the best interest of the farmer in mind. Today it remains the only tractor testing museum in the world. It is also still the only complete tractor test laboratory in the world.
