dc.descriptionThe objective of this work was to evaluate the operational costs of mechanized harvest of coffee in two passes of the harvester. The work was carried out in the Capetinga Farm, Boa Esperança City, State of Minas Gerais, Brazil. The experiments were made with two passes of the harvester, defined according to the green grain index. In the first pass, with average of 30% green grains, velocity was fixed around 0.45 m s -1, and vibration varied at 10.85, 12.50 14.17 and 15 Hz (treatments T1, T2, T3 and T4). In the second pass, carried out in the same plots of the first pass, with average of 10% green grains, vibration was fixed in 16.67 Hz, and velocity varied at 0.60, 0.72, 0.29 and 0.45 m s -1 (treatments T1, T2, T3 and T4). It was utilized a completely randomized design with four replications, in plots with 40 plants per line, in average. For the analysis of harvest costs, the mechanized harvest was compared with the manual one. The total cost reduction of the mechanized harvest is 62.36% in relation to the manual harvest, with the operational speed 0.45 m s -1 in the two passes.
