Repair Cost of Tractors and Agricultural Machines in Family Farms

The mechanization cost in agriculture institute between 20% and 30% of the total production cost. The repair cost of agriculture machines is the second important element of the operation cost of the machines. The paper presents problems related to the calculation of the repair costs and analysis of selected family farms in Poland. The paper argues that there is no precise method for the calculation of the repair costs. The variation of factors influencing the costs, such as exploitation conditions, machines quality or prices relations; causes that the coefficients used in the calculations are not universal and differ between different countries.
