Abstract
The purpose of this study is: (1) to determine the reliability of power indexes in making estimates of horsepower of engines; (2) to determine the reliability of speed indexes in making estimates of operating speed of engines; (3) to determine the reliability of fuel consumption indexes in making estimates of fuel economy of engines.
Performance data for this study were taken from the Nebraska Tractor Test reports and from unpublished Tractor Test data. The tractors used in this analysis were selected from the 1965 Nebraska Tractor Test Summary Sheet. The models were selected on the basis of four-cycle, normally aspirated, current models tested at the Tractor Testing Laboratory and marketed in the United States, excluding tractors under 10 bhp and those with power-absorbing devices in the drive line.The tractors were subdivided into populations by fuel type.The populations include 51 gasoline, 48 diesel, and 24 propane models. Calculations were made using the data given on the individual test reports for the selected tractors.
