y Ashley Washburn, '02 Farm equipment has changed dramatically since the University <strong>of</strong> Nebraska–Lincoln Tractor Test Laboratory poured its first concrete track in 1956. That one replaced the original track made <strong>of</strong> compacted soil. In the summer <strong>of</strong> 2007, the aging track was demolished and replaced with a new one that can better accommodate modern tractors, which are wider, heavier and faster than their predecessors. <strong>The</strong> new track is made from a special concrete blend that is 12 percent stronger than the concrete used for airport runways, said Roger Hoy, pr<strong>of</strong>essor <strong>of</strong> agricultural engineering and director <strong>of</strong> the lab. 14. Spring20.0.8 <strong>The</strong> track also is wider and thicker than the original 22 feet wide, compared to 15, and nine inches thick instead <strong>of</strong> seven. <strong>The</strong> new track also features banked edges that will allow the lab to test tractors that travel at higher speeds. <strong>The</strong>se advancements will make it possible for the lab to test a wider variety <strong>of</strong> tractors. For example, Hoy said, his staff was able to test a Case IH tractor that would have been too wide and heavy to fit on the old track. In the past, the team would have tested that machine at the Lincoln Airport. Construction on the track began shortly after Memorial Day and concluded in August. HWS Consulting Group, the Lincoln engineering firm that designed the original track, also designed the new one. Another Lincoln company, TCW Construction, built the new track. Hoy said he hoped the track would last another 50 years. “We tried to anticipate what needs we would have in the future,” he said. UNL is the only university in the United States to have a tractor test lab, which was formed because a state senator purchased a tractor and was unhappy with its performance. Wilmot Crozier introduced a bill in the 1918 Legislature requiring any tractor sold in Nebraska to be tested to ensure it performed as the manufacturer claimed. Thus, the Tractor Test Lab opened in 1919. Nebraska is still the only state to have such a law, Hoy said, but almost all models are evaluated at the lab anyway. <strong>The</strong> lab also is the <strong>of</strong>ficial U.S. testing site for the Organization for Economic Cooperation and Development, which regulates tractor standards worldwide. On average, the lab tests 25 tractors annually. <strong>The</strong> lab’s operation and maintenance costs, including construction <strong>of</strong> the new track, are funded through manufacturers’ fees. Ed Heys <strong>of</strong> the Association <strong>of</strong> Equipment Manufacturers said the lab is one <strong>of</strong> the finest <strong>of</strong> its kind in the world, and added; “<strong>The</strong>ir future looks bright—and busy.”
