The results showed that significant linear relations exist between the power and the price of new tractors and combine harvesters. The average price per h.p. of EU-15 combines was 28 % larger than this of Russian machines and the price of EU-tractors was 73 % larger than the price of Belarus tractors. Regression relations between the age or summarized working time and the price of second hand 80 – 100 hp tractors in Germany were also investigated and revealed a logarithmic relation of the price.
