The present work was carried out in experimental areas of the Los Palacios Base Scientific and Technological Unit in the province of Pinar del Río. The mechanized transplanting process of rice was investigated, with the objective of increasing productivity through the efficient use of the components of the shift time of the ERP-60 transplanter. The results obtained indicate that an increase in productivity per hour of exploitation time of 0.382 ha/h is achieved, equivalent to 3.0 ha per 8-hour shift. [ABSTRACT FROM AUTHOR]

In Cuba, the rice harvest is an operation that is carried out with the help of agricultural machinery, which represents strong investments. For this reason, the dynamics of the production process requires that the harvesting machines be in perfect technical condition during this period, because of that it is necessary to properly organize and plan the maintenance and repair system to ensure the increase of productivity efficiently. In the present work, the main results and experiences obtained in the research carried out during the mechanized harvesting of rice in Los Palacios Agribusiness Company of Grains in Pinar del Río Province, are stated. That was made to serve as a basis for decision making during the harvest of this precious grain; if one takes into consideration the large number of harvesters of different models that have been introduced in the country in recent years.

The research was carried out in the conditions of harvest and repair of "Sierra Maestra", Agricultural Base Business Unit (UEBA) in New Holland L-521, L-624, L-626 rice harvesters, in the daily technical maintenance operations, every 30 h periods, with the objective of estimating their maintainability. Through mathematical analysis, average time of daily and periodic technical maintenance every 30 h was determined. In the research, the estimation of maintainability for real operation conditions is made for the first time. Among the most significant results is that for the harvesters evaluated, the maintainability curve shows that there is between 95.8 and 97% probability that the daily technical maintenance will be carried out in two hours; while in technical maintenance every 30 h the probability is between 74 and7 8% in the same period of time.

The rice is at the moment the most automated cultivation in Cuba reaching a level of 97 %, and its economic importance resides in the demand of this cereal for our population's consumption. The technological properties of the machines croppers of rice characterize, the quality of the execution of the technological processes during the realization of the crop. For what should be increased the agricultural yields, to improve the use and to increase the effectiveness of the agricultural machinery for the sake of reaching the biggest results at the smallest cost. The research offers the determination of the main technological parameters and of operation of the one combined of rice New Holland that influence in the time of shift during the realization of the crop in the Rice Enterprise "Los Palacios" of the Pinar del Río province, Cuba.
