GODOY-LOPEZ, Allen et al. Improvement of the Design and Evaluation of the Conventional Grain Planter "GUAJIRO AM 2010-1-5T". Rev Cie Téc Agr [online]. 2019, vol.28, n.4, e05.  Epub 01-Dez-2019. ISSN 2071-0054.

The development of agricultural production requires the use of machinery to increase productivity and quality of work, a problem that is becoming more pressing in short-cycle crops (corn and beans), creating two possible scenarios, the acquisition of machinery or the improvement of the existing ones. On this last scenario, in recent years, the Ministry of Agriculture of Cuba (MINAG) has been projecting. For this reason the present work has as objective to redesign the grain seeder "Guajiro AM 2010-1-5T"for its improvement. To fulfill this objective, the machine was redesigned fundamentally for grain transmission and distribution systems, for which the resistance analysis by the finite element method (MEF) and its operation were made, through the help of the specialized softwaresMechanical Desktop 2008 and SolidWorks 2010. Later, a prototype was built which was tested in static and working conditions during the planting of corn and beans. Finally, the cost sheet was prepared and the economic feasibility of its development was determined. The main results showed that the design variant developed is capable of meeting the requirements of resistance, performance and safety necessary for these machines, in addition to meeting the quality requirements during the planting of beans and corn. The economic analysis showed the feasibility of its improvement, with an economic effectiveness of $14,340.25 (Cuban peso).
