DE LA ROSA-ANDINO, Alain Ariel et al. Evaluation of Aggregates Formed with Tractor YTO x1204, Harrows and Land Plane. Rev Cie Téc Agr [online]. 2022, vol.31, n.2  Epub 13-Mayo-2022. ISSN 2071-0054.

The present work was developed with the objective of analyzing work efficiency indicators of agricultural aggregates formed with a YTO x1204 tractor, harrows and a land plane, in order to establish them partially for the future planning of agricultural works in the Agroindustrial Company of Grains “Fernando Echenique” from Granma Province. To carry out the research, Cuban standards were used as well as instructions and methodologies referred on specialized literature. The results showed that most of the values ​​of the efficiency indicators of these agricultural groups are below the technical possibilities. However, the utilization coefficient of the working width (εβ) for the land plane, the utilization coefficient of the working speed (εV) of the 52-disc heavy harrow and the utilization coefficient of work shift (τ ) of the three aggregates are classified as acceptable. It is concluded that the magnitudes of real productivity (Wr) obtained behaved below the real possibilities of the set with magnitudes of 14.65; 17.71 and 29.1 ha shift-1, respectively, which is due to violations of the kinematic parameters during work.

Palabras clave : Working Width; Working Speed; Working Depth; Shift Time and Productivity.
