PEREZ-OLMO, Claudio B. et al. Behavior of Operating Indicators of Massey Fergunson 5650 Grain Harvester. Rev Cie Téc Agr [online]. 2018, vol.27, n.4, e08. ISSN 2071-0054.

Due to the high cost of Massey Fergunson 5650 grain harvesters, proper use of these machines is necessary. In Ciego de Ávila Province, with many areas dedicated to the cultivation of grains, these machines have a wide use. The work consisted of evaluating the balance of shift time of the harvesters, technical availability coefficient, the most frequent failures and productivity and agricultural yield of the fields. The coefficient of technical availability 0.82, still has the potential to improve the use of machines and it is possible to take technical and organizational measures. The most frequent faults were in the cutting system and in the harvest system. The productivity of the harvesters with an average of 1.6 t / h was low considering the potential of these machines. The main causes of this poor performance are given by low effective use of shift time (average 69%), low agricultural yields (average of 1.15 t / ha) and inadequate state of the fields for harvesting.

Palavras-chave : Productivity; reliability; time balance; technical availability coefficient.
