- W2183799254 abstract "Tractors are the source of mobile power for the agricultural industry, and it is important to remember that power means rate of work. In step with progress in the tech nology of design and production, it is pertinent to occasionally appraise the cost of power supply to farming. This may be expressed by three values. Firstly, the purchase cost, that is, the capital cost per unit of potential power. Secondly, the oper ating cost: in which overall efficiency (and thus fuel used per acre worked) is a major item. Thirdly, the cost per unit weight: since tractors are essen tially processed raw materials and weight is a factor affecting tractive efficiency. The data presented in this paper is the result of analyses of the rela tionship between cost and perfor mance which were carried out in the 1962 and 1966 seasons for one region of this continent, namely, Southern Ontario. The three considerations enumerated above were developed as five parameters, as follows: 1. capital cost per pto horsepower, 2. capital cost per drawbar horsepower, 3. rela tive engine efficiency, 4. tractor con version efficiency, and 5. capital cost per unit weight. In each year, cal culations were made for all the trac tors offered in the region for which University of Nebraska Test data were available; that is, 61 tractors in 1962 and 79 tractors in 1966. Although the results of this survey relate quantitatively to Southern Ontario, the relative values obtained should be indicative of the situation in similar areas and modified only by differences in transportation costs from the point of manufacture. Southern Ontario is a highly mechan ized area of diversified agricultural production, and the results of this analysis may be regarded as repre sentative of fully mechanized regions" @default.
