The goal of the work is to find and describe the effect of the shape and size of the land on the energy intensity of an agricultural operation. This effect is expressed by means of coefficient KS that is determined by a theoretical calculation; the correctness of the algorithm is confirmed by coefficient KSP determined by a field-laboratory measurement. Both coefficients are determined for seven different lands and the results are compared mutually. The results are also indicated for the calculation of fuel consumption and machine performance with respect to the land size and shape. With the help of these relations, a graph was set up for the dependence of the performance (ha/h) and consumption (l/ha), (l/h) on the KS coefficient during ploughing.Keywords:
