History of Society of Automotive Engineers Agricultural Tractor Test Code

This paper outlines some of the history involved in the development of the SAE/ASAE Agricultural Tractor Test Code, along with some thoughts for the future. Much credit should be given to the men of the tractor industry, the Nebraska tractor test group and the technical societies for their vision and leadership. This work has enabled us to arrive at the position of creditability with respect to tractor power performance that we have with our customers. The integrity and dedication we have within our tractor industry, which includes all phases; namely, the companies, the technical societies and the Nebraska Tractor Test Laboratory, the writers feel confident we will continue to meet and solve the problems arising in the future.
