Using Tractor Test Data for Selecting Farm Tractors
The Nebraska Tractor Test Laboratory (NTTL) at the University of Nebraska is the official U.S. tractor testing station for the Organization for Economic Cooperation and Development. This laboratory has the responsibility for testing all models of tractors sold in the state of Nebraska, and it publishes the results of all tests it conducts. It also tests tractors manufactured in the United States and sold in international markets.

Predicting Tractor Diesel Fuel Consumption
Ability to predict tractor fuel consumption is very useful for budgeting and management. The objective of this factsheet is to develop relationships using field measurements and Nebraska Tractor Test Laboratory results to estimate tractor fuel consumption. Using these equations, farmers can estimate and compare the fuel consumption for different operating and loading conditions.
