Abstract : It would be of benefit to users of agricultural vehicles to have available computer models to compare the performance of different machines. Such models are already widely available to prospective purchasers of military vehicles. The main difficulty in developing similar models for agricultural vehicles is the wide variety of operations which are carried out on farms. One important area, however, where such models can be developed are for heavy draught operations such as ploughing, cultivating, sub-soiling etc. This paper describes models of varying complexity which can be used to predict the power output or workrate of a tractor on such operations. The simpler models need only a programmable calculator, but the more user-friendly versions would require a microcomputer. The programs can be used to compare the workrates of tractors of different design and these results can then be used in linear programs of the general farm management system to determine the effects on overall profitability.
