VALDES HERNANDEZ, Pedro Antonio; CRESPO TORRES, Pascual Daniel  and  GOMEZ AGUILA, María Victoria. Operation Indicators of the Unit Tractor MF 275-KUHN MC 90S TWIN Forage Corn Harvester. Rev Cie Téc Agr [online]. 2021, vol.30, n.3  Epub July 01, 2021. ISSN 2071-0054.

The objective of the research carried out was to determine the operating indicators of the unit MF 275 tractor, UHN MC 90S TWIN corn (Zea mayz) forage harvester and the trailer, belonging to “La Ceibana” Farm in Trujillo State. In this work it was obtained that the operating time of the trial corresponds to 82 h and the clean time 17.77 h representing 21.7%, which means a consumption of unproductive time of 78% and a coefficient of use of the time of exploitation of 22%, so there is a reserve for improving the efficiency of the forage corn harvesting process. A productivity per hour of clean time of 5 868.84 kg / h was obtained and a productivity per hour of exploitation time of 1 271.42 kg / h, which is in accordance with the technical characteristics of the machine. Average values are obtained for each control shift, in the case of the mass of 5 487.37 kg, a speed of 3.13 km / h and a fuel consumption of 50.24 L, which yields a value of 12.56 L / h of operation, which is within the working range for this type of agricultural set, with coefficients of variation below of 15.7%, which means a low dispersion of the data obtained and there was a normal distribution of the data obtained.

Keywords : Operation Times; Productivity; Coefficients.
