VALDES-HERNANDEZ, Pedro A. et al. Energy Costs of Belarus 510 Tractor and JF-50 Forage Chopper. Rev Cie Téc Agr [online]. 2019, vol.28, n.3, e01.  Epub 29-Abr-2019. ISSN 2071-0054.

This investigation is part of the studies carried out by the Faculty of Technical Sciences, the Agricultural Mechanization Center (CEMA) of the Agrarian University of Havana (UNAH) and the Institute of Animal Science (ICA), on the evaluation of agricultural assemblies for the production of animal feed. It was developed with the objective of determining the energy costs of the Russian BELARUS 510 Tractor and of the Brazilian JF-50 forage chopper. It is determined that the total energy costs depend, to a greater extent, on the energy sequestered in fuel (ESc), with a value of 103,73 MJ/h and 53% as the highest value. The energy sequestered in lubricants and filters (ESl) represented the lowest dependency with a value of 5,19 MJh, being 2,65% the lowest value. Total hourly energy costs (EST) amount to 195,48 MJ/h and energy costs total per unit mass processed (ESt) to 365 MJ/t.

Palavras-chave : costs; sequestered energy; fuel.
