Long-term Cost Analysis of Mid-performance Harvesters in Czech Conditions
Original language description
The harvester technology is increasingly used in Central and Eastern Europe, yet is still costly and thus has be used efficiently. This study focused on the analysis of the development of operational costs of two mid-performance harvesters (JD770D and JD1070D) over a ten-year period, from 2006 to 2017. The costs were aggregated into four categories: depreciation, services, material, and personnel costs) and were analysed annually. The Harvesters were used in thinning under different conditions, which has to be considered when interpreting our results. The mean stem size processed by the JD770D was 0,11 m3 under bark (u.b.) and it harvested 16,793 m3 u.b. per year of timber operating for 3,166 machine hours (MH) per year. The mean costs per m3 u.b. of produced timber ranged from 6,6 to 10,2 euro/m3 u.b. The JD1070D was harvesting trees with a mean stem size of 0,29 m3 u.b. and it harvested 26,837 m3 u.b. per year on average, with an operational time of 3,067 MH. The mean costs per m3 u.b. of produced
