Maintainability of New Holland Rice Harvesters in "Los Palacios" Company, Cuba.

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.
