Historical Sketch Of Tractor Testing, Nebraska Tractor Test Lab
Nebraska Tractor Tests
A historical sketch of Tractor Testing at the University of Nebraska-Lincoln. Lester F. Larsen. Engineer in charge since 1947, visits with George S. Round, Professor of Agricultural Communications at the University about individuals who made contributions to the successful program. He also reports on 1,155 tests conducted up to January I, 1974, and contrasts tractors of 1974 with those of 20, 30 or more years ago . Testing fee schedules are reviewed in a self-supporting project favorably known round the world.
