A decision related to the selection of the optimum agricultural tractor is considered by farmers as crucial, having a decisive influence on the economic effect of the farm. This is due to the need to adjust the technical and operating parameters of the tractor to the possessed machines. The paper proposes a method to support the decision of selecting an agricultural tractor that uses fuzzy logic, which allows taking into account the measurable and immeasurable criteria. Based on the theory of fuzzy sets, a procedure of ranking these criteria was suggested. The obtained ratio D c decision clearly hierarchizes the considered alternative tractors.
